RESUMEN

Ruptured vertebral artery dissecting aneurysms(VADA) carry a poor prognosis owing to the high rates of rebleeding, stroke, and mortality without appropriate treatment. Various endovascular techniques are employed to treat these aneurysms. Deconstructive techniques, involving internal trapping with coils, often achieve complete angiographic occlusion at higher rates; however, they carry a risk of medullary infarction. Reconstructive techniques using neck-bridge stents preserve the parent vessel and reduce perioperative morbidity. Nevertheless, these techniques are associated with a higher rate of aneurysmal rebleeding or recurrence. Optimal treatment modalities should be chosen based on the anatomical characteristics of the aneurysm and the trade-off between risks and benefits.

RESUMEN

BACKGROUND: Prompt diagnosis and treatment of vertebral artery dissection (VAD) is critical for preventing stroke. The use of emboli detection studies (EDS) using Doppler ultrasonography is an emerging method that has been proposed to predict stroke risk and guide subsequent treatment. Limited data exists on the predictive value of this emerging modality in the posterior circulation. This study aims to assess the predictive value of emboli detection studies (EDS) in forecasting inpatient stroke in VAD patients and identify associated risk factors. Patients were recruited between January 2009 and January 2018. METHODS: We performed a retrospective analysis of 104 consecutive patients with VAD who underwent EDS at our institution. Patients underwent transcranial ultrasonography for detection of microemboli and were followed clinically and radiographically thereafter for evidence of stroke. RESULTS: A total of 104 patients with spontaneous (58 %), traumatic (39 %) or iatrogenic (4 %) VAD were included in our analysis. Stroke occurred more frequently in patients with spontaneous VAD compared to traumatic VAD (p < 0.001). Microemboli were detected in 17 patients (16 %), including 18.3 % of spontaneous VAD, 12.5 % of traumatic VAD, and 25 % of iatrogenic VAD. 61 patients (59 %) suffered a posterior circulation stroke, however there was no significant association between detection of microemboli and stroke events (60 % of patients without microemboli vs. 53 % of patients with ≥ 1 HITS during EDS; p = 0.6). Similarly, no microemboli were detected in any of the patients who went on to develop a delayed stroke. CONCLUSIONS: In our single-institution retrospective analysis of patients with VAD, the detection of microemboli on EDS was not associated with stroke nor was it predictive of delayed stroke. Additionally, patients with spontaneous VAD may be at higher risk for stroke compared to traumatic VAD.

RESUMEN

Cervical arterial dissection (CAD) is a common cause of stroke in young people which can be classified as either spontaneous or traumatic. The primary initial symptoms are headache, neck pain, and dizziness. Recently, a 57-year-old woman experienced a severe headache after using a cervical neck traction device. Radiological examination of the head and neck revealed right vertebral artery dissection, which emphasizes the importance of recognizing that using cervical neck traction devices increases the risk of traumatic vertebral artery dissection.

RESUMEN

Cervicocerebral artery dissection stands out as a significant contributor to ischemic stroke in young adults. Several studies have shown that arterial tortuosity is associated with dissection. We searched Pubmed and Embase to identify studies on the association between arterial tortuosity and cervicocerebral artery dissection, and to perform a review on the epidemiology of cervicocerebral artery tortuosity and dissection, pathophysiology, measurement of vessels tortuosity, strength of association between tortuosity and dissection, clinical manifestation and management strategies. The prevalence of tortuosity in dissected cervical arteries was reported to be around 22%-65% while it is only around 8%-22% in non-dissected arteries. In tortuous cervical arteries elastin and tunica media degradation, increased wall stiffness, changes in hemodynamics as well as arterial wall inflammation might be associated with dissection. Arterial tortuosity index and vertebrobasilar artery deviation is used to measure the level of vessel tortuosity. Studies have shown an independent association between these two measurements and cervicocerebral artery dissection. Different anatomical variants of tortuosity such as loops, coils and kinks may have a different level of association with cervicocerebral artery dissection. Symptomatic patients with extracranial cervical artery dissection are often treated with anticoagulant or antiplatelet agents, while patients with intracranial arterial dissection were often treated with antiplatelets only due to concerns of developing subarachnoid hemorrhage. Patients with recurrent ischemia, compromised cerebral blood flow or contraindications for antithrombotic agents are usually treated with open surgery or endovascular technique. Those with subarachnoid hemorrhage and intracranial artery dissection are often managed with surgical intervention due to high risk of re-hemorrhage.

RESUMEN

If severe cervical spinal cord injury or severe cervical vertebral fracture, subluxation or luxation is confirmed, 20-40% of the cases have vertebral artery dissection or occlusion. These can be asymptomatic, but can cause additional neurological damage in addition to cervical myelon and cervical nerve root symptoms. Vertebral artery dissection can be caused by direct injuries, stab wounds or gunshot wounds. Indirect vertebral artery dissection can occur at the same time as subluxation, luxation, or complex fractures of the cervical vertebra. CTA is the examination procedure of choice. In many cases, digital subtaction angiography examination and, if necessary, neurointerventional treatment must precede open neurosurgery. In our report, in the first patient, complete luxation of the C.VI vertebra caused unilateral vertebral artery 2-segment dissection-occlusion, while in our second patient, a stab injury caused direct vertebral artery compression and dissection. The occlusion of the vertebral artery did not cause neurological symptoms in any of the cases. In both of our cases, parent vessel occlusion was performed at the level of the vertebral artery injury before the neurosurgical operation.

RESUMEN

CLINICAL ISSUE: Craniocervical dissections are among the most common causes of stroke in people aged under 50 years, which is why it is essential to clarify, diagnose, and treat them as quickly as possible. Dissections usually occur spontaneously due to bleeding into the vessel wall. The affected segments are usually the motion segments of the internal cerebral artery (C1 segment) and the vertebral artery (V3 segment). Clinically, there is head and/or neck pain and neurologic symptoms, which can vary according to the localization of the dissection. PRACTICAL RECOMMENDATIONS: Pathognomonic is the detection of an intramural hematoma due to bleeding into the vessel wall. This can best be detected by magnetic resonance imaging (MRI) in native, fat-saturated T1 sequences (black-blood sequence). In addition, contrast-enhanced angiography should be performed using MRI or, alternatively, computed tomography (CT). As there is an increased risk of embolic or hemodynamically induced strokes, prophylactic treatment should be initiated immediately; it remains a case-by-case decision whether antiplatelet agents or oral anticoagulants are chosen for this purpose.

RESUMEN

OBJECTIVE: A retrospective study of cases of endovascular treatment of dissection of the vertebral artery with subarachnoid hemorrhage was conducted. MATERIAL AND METHODS: Data were 11 cases of vertebral artery dissecting aneurysm (VADA) among 291 consecutive subarachnoid hemorrhage patients who underwent clipping or endovascular treatment at Ota Memorial Hospital. Classified into 4 patterns based on the location of the dissection and posterior inferior cerebellar artery (PICA): pre-PICA, post-PICA, involved PICA, and non-PICA. And one of the cases had bilateral vertebral artery dissection, and computational fluid dynamics analysis was included in the study. RESULTS: Ruptured VADA occurred in 11 of the 291 patients (3.8%). Endovascular treatment was performed in 8 of these 11 patients. Postoperative diffusion-weighted imaging detected no high-intensity lesions and no postoperative ischemic complications or rebleeding occurred in any patient. In a case of bilateral VADA, computational fluid dynamics analysis of very low or high wall shear stress at the dissection, low aneurysm formation indicator, and high oscillatory shear index may be considered rupture factors. CONCLUSIONS: Treatment strategies for each branching pattern of PICA can prevent rupture and avoid ischemic complications. And prediction of the rupture side is important in patients with bilateral dissection to consider the appropriate treatment and timing.

RESUMEN

OBJECTIVE: High-resolution magnetic resonance imaging (HR-MRI) can provide valuable insights into the evaluation of vascular pathological conditions, and 3D digital subtraction angiography (3D-DSA) offers clear visualization of the vascular morphology and hemodynamics. This study aimed to investigate the potential of a multimodal method to treat unruptured vertebral artery dissection aneurysms (u-VADAs) by fusing image data from HR-MRI and 3D-DSA. METHODS: This observational study enrolled 5 patients diagnosed with u-VADAs, who were scheduled for interventional treatment. The image data of HR-MRI and 3D-DSA were merged by geometry software, resulting in a multimodal model. Quantified values of aneurysm wall enhancement (AWE), wall shear stress (WSS), neck velocity, inflow volume, intra-stent flow velocity (ISvelocity), and intra-aneurysmal velocity (IAvelocity) were calculated from the multimodal method. RESULTS: We found the actual lengths of u-VADAs in the multimodal model were longer than the 3D-DSA model. We formulated surgical plannings based on the WSS, IA velocity, and neck velocity. The post-operative value of IAvelocity, neck velocity, and follow-up quantified values of AWE were decreased compared with the pre-operative condition. After that, u-VADAs were complete occlusion in four patients and near-complete occlusion in one patient during the 6th-month follow-up after surgery. CONCLUSION: The multidimensional method combining HR-MRI with 3D-DSA may provide more valuable information for treating VADAs, with the potential to develop effective surgical planning.

RESUMEN

Introduction: Spontaneous cervical artery dissection (sCAD) is a rare vasculopathy whose trigger is still unknown. We hypothesized that autoimmunity against components of the vascular wall might play a critical role in sCAD and examined anti-collagen type I antibodies in patients with sCAD, acute ischemic stroke, patients with thromboendarterectomy, and controls. Methods: Fifty-seven patients with sCAD (age 45.7 ± 10.2 years, female 18 (31.6%)) were prospectively enrolled in four German stroke centers. Blood samples were collected at baseline, at day 10 ± 3, and after 6 ± 1 months. Patients with ischemic stroke not related to CAD (n=54, age 56.7 ± 13.7 years, female 15 (27.8%)), healthy probands (n=80, age 57.4 ± 12.9 years, female 56 (70%)), and patients undergoing thromboendarterectomy of the carotid artery (n=9, age 70.7 ± 9.3 years, female 2 (22.2%)) served as controls. Anti-collagen type I antibodies were determined by enzyme-linked immunosorbent assays (ELISAs). Results: Patients with acute sCAD had higher serum levels of anti-collagen type I antibodies (33.9 ± 24.6 µg/ml) than probands (18.5 ± 11.0 µg/ml; p <0.001) but lower levels than patients with ischemic stroke not related to sCAD (47.8 ± 28.4 µg/ml; p=0.003). In patients with sCAD, serum levels of anti-collagen type I antibodies were similar in the acute, subacute, and chronic phase. Levels of anti-collagen type I antibodies significantly correlated with circulating collagen type I (rho=0.207, p=0.003). Conclusion: Anti-collagen type I antibodies seem not to represent a trigger for acute sCAD or ischemic stroke but may rather be linked to the metabolism and turnover of collagen type I.

RESUMEN

BACKGROUND: Cervical artery dissection (CAD) is a relevant etiology of transient ischemic attacks and strokes. Several trials explored the significance of specific antithrombotic treatments, i.e. oral anticoagulation (OAC) versus antiplatelet treatment (APT), on recurrent ischemic complications and clinical outcomes. As overall incidence rates of complications were low there is still controversy which antithrombotic treatment should be used. However, up to now there has been no systematic investigation among CAD-patients with ischemic stroke specifically comparing clinical course and outcome of patients with anterior versus posterior CAD. METHODS: We performed an individual participant data analysis of patients with CAD and ischemic stroke. Over a five-year period we pooled data from three sites (i.e. West China Hospital, Chengdu, China as well as Erlangen and Giessen University Hospitals, Germany) and enrolled patients with CAD-associated ischemic stroke. Patient demographics, clinical and in-hospital measures as well as radiological data were retrieved from institutional databases. Clinical follow-up was over 6 months and included data on recurrent ischemic strokes and hemorrhages as well as clinical functional outcome assessed by the modified Rankin Scale dichotomized into favourable (mRS=0-2) and unfavourable. RESULTS: A total of 203 patients with CAD were included of which n=112 had anterior and n=91 had posterior CAD. Patients with posterior CAD were younger (46.0 vs. 41.0 y; p<0.001) than patients with anterior CAD and showed less often arterial hypertension. (42.0 % vs. 28.6 %; p<0.048). Antithrombotic treatment with APT and OAC was similarily distributed among patients with anterior and posterior CAD and not significantly differently related to ischemic or hemorrhagic complications during follow-up (all p=n.s.). Main difference between Chinese and German patients were mode of antithrombotic treatment consisting predominantly of APT in China compared to OAC in Germany. Functional outcome overall was good, yet worse in patients with anterior CAD compared to posterior CAD (80.2 % favorable in anterior CAD vs. 92.2 % in posterior CAD (p=0.014). CONCLUSION: This study provides evidence that anterior and posterior CAD show baseline imbalances regarding age and comorbidity which may affect clinical outcome. There are no signals of superiority or harm of any specific mode of antithrombotic treatment nor relevant discrepancies in clinical outcome among Chinese and German CAD-associated stroke patients.

RESUMEN

BACKGROUND AND PURPOSE: The value of long-term serial imaging of dissecting pseudoaneurysm (dPSA) is poorly characterized. This study investigated the long-term radiographic evolution of dPSA. METHODS: We performed a query in our institutional craniocervical artery dissection registry to identify cases with spontaneous dPSA who had at least one year of follow-up with serial angiographic imaging. We performed Wilcoxon rank-sum pairwise comparison test to determine if there was a significant change in the aneurysm size over time. RESULTS: This observational cohort study included 76 patients (46 females; 64 dPSA in the internal carotid artery [ICA] and 12 in the vertebral artery [VA]) with a median age of 49.5 years (range 24-77). The initial median dPSA size was 8 mm (interquantile range(iqr) = 5.88-11mm), and the final median dPSA size was 7 mm (iqr = 4-11 mm). Most patients had either no change or reduction in dPSA size in the serial follow-up, with no significant change over time. All the patients had favorable outcomes at the last follow-up, and most patients were symptom-free from dPSA (92 %). Two patients (2.6%) experienced recurrent ischemic strokes in the same territory as the initial ischemic stroke without any change in dPSA size. CONCLUSION: Further serial scans for dPSA after one year may be deferred in the absence of interim clinical symptoms as most dPSA either remains stable or decreases in size. Recurrent stroke, although a rare event, was not associated with an increase in dPSA size.

RESUMEN

BACKGROUND: It is uncertain whether antiplatelets or anticoagulants are more effective in preventing early recurrent stroke in patients with cervical artery dissection. Following the publication of the observational Antithrombotic for STOP-CAD (Stroke Prevention in Cervical Artery Dissection) study, which has more than doubled available data, we performed an updated systematic review and meta-analysis comparing antiplatelets versus anticoagulation in cervical artery dissection. METHODS: The systematic review was registered in PROSPERO (CRD42023468063). We searched 5 databases using a combination of keywords that encompass different antiplatelets and anticoagulants, as well as cervical artery dissection. We included relevant randomized trials and included observational studies of dissection unrelated to major trauma. Where studies were sufficiently similar, we performed meta-analyses for efficacy (ischemic stroke) and safety (major hemorrhage, symptomatic intracranial hemorrhage, and death) outcomes using relative risks. RESULTS: We identified 11 studies (2 randomized trials and 9 observational studies) that met the inclusion criteria. These included 5039 patients (30% [1512] treated with anticoagulation and 70% [3527]) treated with antiplatelets]. In meta-analysis, anticoagulation was associated with a lower ischemic stroke risk (relative risk, 0.63 [95% CI, 0.43 to 0.94]; P=0.02; I2=0%) but higher major bleeding risk (relative risk, 2.25 [95% CI, 1.07 to 4.72]; P=0.03, I2=0%). The risks of death and symptomatic intracranial hemorrhage were similar between the 2 treatments. Effect sizes were larger in randomized trials. There are insufficient data on the efficacy and safety of dual antiplatelet therapy or direct oral anticoagulants. CONCLUSIONS: In this study of patients with cervical artery dissection, anticoagulation was superior to antiplatelet therapy in reducing ischemic stroke but carried a higher major bleeding risk. This argues for an individualized therapeutic approach incorporating the net clinical benefit of ischemic stroke reduction and bleeding risks. Large randomized clinical trials are required to clarify optimal antithrombotic strategies for management of cervical artery dissection.

RESUMEN

Vertebral artery dissection is a rare pathology that can cause ischemic stroke in young people. Cervical massage, especially improper pulling manipulation, is a cause of vertebral artery dissection. We present a case of 32-year-old woman who developed acute multiple posterior circulation ischemic cerebral infarctions as a result of left vertebral artery V4 segment dissection after receiving neck massage. She underwent emergency vertebral artery stent implantation at the site of the dissection. Symptoms were relieved the day after treatment. The patient recovered without adverse complications or endovascular restenosis in the following year.

RESUMEN

Cervical artery dissection (CeAD) is the primary cause of ischemic stroke in young adults. Monogenic heritable connective tissue diseases account for fewer than 5% of cases of CeAD. The remaining sporadic cases have known risk factors. The clinical, radiological, and histological characteristics of systemic vasculopathy and undifferentiated connective tissue dysplasia are present in up to 70% of individuals with sporadic CeAD. Genome-wide association studies identified CeAD-associated genetic variants in the non-coding genomic regions that may impact the gene transcription and RNA processing. However, global gene expression profile analysis has not yet been carried out for CeAD patients. We conducted bulk RNA sequencing and differential gene expression analysis to investigate the expression profile of protein-coding genes in the peripheral blood of 19 CeAD patients and 18 healthy volunteers. This was followed by functional annotation, heatmap clustering, reports on gene-disease associations and protein-protein interactions, as well as gene set enrichment analysis. We found potential correlations between CeAD and the dysregulation of genes linked to nucleolar stress, senescence-associated secretory phenotype, mitochondrial malfunction, and epithelial-mesenchymal plasticity.

RESUMEN

Importance: Cervical artery dissection is the most common cause of stroke in younger adults. To date, there is no conclusive evidence on which antithrombotic therapy should be used to treat patients. Objective: To perform an individual patient data meta-analysis of randomized clinical trials comparing anticoagulants and antiplatelets in prevention of stroke after cervical artery dissection. Data Sources: PubMed.gov, Cochrane database, Embase, and ClinicalTrials.gov were searched from inception to August 1, 2023. Study Selection: Randomized clinical trials that investigated the effectiveness and safety of antithrombotic treatment (antiplatelets vs anticoagulation) in patients with cervical artery dissection were included in the meta-analysis. The primary end point was required to include a composite of (1) any stroke, (2) death, or (3) major bleeding (extracranial or intracranial) at 90 days of follow-up. Data Extraction/Synthesis: Two independent investigators performed a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and inconsistencies were resolved by a principal investigator. Main Outcomes and Measures: The primary outcome was a composite of (1) ischemic stroke, (2) death, or (3) major bleeding (extracranial or intracranial) at 90 days of follow-up. The components of the composite outcome were also secondary outcomes. Subgroup analyses based on baseline characteristics with a putative association with the outcome were performed. Logistic regression was performed using the maximum penalized likelihood method including interaction in the subgroup analyses. Results: Two randomized clinical trials, Cervical Artery Dissection in Stroke Study and Cervical Artery Dissection in Stroke Study and the Biomarkers and Antithrombotic Treatment in Cervical Artery Dissection, were identified, of which all participants were eligible. A total of 444 patients were included in the intention-to-treat population and 370 patients were included in the per-protocol population. Baseline characteristics were balanced. There were fewer primary end points in those randomized to anticoagulation vs antiplatelet therapy (3 of 218 [1.4%] vs 10 of 226 [4.4%]; odds ratio [OR], 0.33 [95% CI, 0.08-1.05]; P = .06), but the finding was not statistically significant. In comparison with aspirin, anticoagulation was associated with fewer strokes (1 of 218 [0.5%] vs 10 of 226 [4.0%]; OR, 0.14 [95% CI, 0.02-0.61]; P = .01) and more bleeding events (2 vs 0). Conclusions and Relevance: This individual patient data meta-analysis of 2 currently available randomized clinical trial data found no significant difference between anticoagulants and antiplatelets in preventing early recurrent events.

RESUMEN

OBJECTIVE: Flow diverter device (FDD) has emerged as the reconstruction technique for treating ruptured dissecting vertebral artery Aneurysms (VADA), but data on feasibility regarding re-rupture risk and timing of Aneurysm obliteration following FDD treatment is still limited. Therefore, this study aimed to evaluate the safety and efficacy of FDD in the treatment of VADAs presenting with subarachnoid hemorrhage (SAH). METHODS: We retrospectively reviewed patients with ruptured VADA presenting with subarachnoid hemorrhage who underwent FDD placement at our institution between 2015 and 2023. Patient demographic data, Aneurysm configuration, and occlusion status were analyzed. RESULTS: Thirteen patients with SAH from VADA rupture underwent FDD implantation. The average size of the largest diameter of the Aneurysm was 11.2 mm (range 6.5-21 mm). Eight of 13 (61.5 %) patients had their Aneurysms completely obliterated within 2 weeks after the procedure. The small dissecting Aneurysm (d = 0.636, p = 0.002) and degree of intra-Aneurysmal contrast stasis (d = 0.524, p = 0.026) were associated with rapid Aneurysm occlusion, according to the Somer's d coefficient. There were no ischemic or hemorrhagic complications at the average clinical follow-up of 28.4 months (range 5-67 months) and average angiographic follow-up of 20.1 months (range 3-60 months). A favorable outcome (mRS 0-2) was achieved in 12 patients (92.3 %). CONCLUSIONS: FDD is safe and effective for the reconstruction of acutely ruptured VADAs. In addition, our study emphasizes that small dissecting Aneurysms tend to be rapidly obliterated after flow diversion, which eliminates the risk of re-rupture during the acute phase of subarachnoid hemorrhage.

RESUMEN

BACKGROUND: Vertebral artery dissections (VADs) may extend from the extracranial to the intracranial vasculature (e+iVAD). We evaluated how the characteristics of e+iVAD differed from those of intracranial VAD (iVAD). METHODS AND RESULTS: From 2002 to 2019, among consecutive patients with cervicocephalic dissection, those with iVAD and e+iVAD were included, and their clinical characteristics were compared. In patients with unruptured dissections, a composite clinical outcome of subsequent ischemic events, subsequent hemorrhagic stroke, or mortality was evaluated. High-resolution magnetic resonance images were analyzed to evaluate intracranial remodeling index. Among 347 patients, 51 (14.7%) had e+iVAD and 296 (85.3%) had iVAD. The hemorrhagic presentation occurred solely in iVAD (0.0% versus 19.3%), whereas e+iVAD exhibited higher ischemic presentation (84.3% versus 27.4%; P<0.001). e+iVAD predominantly presented steno-occlusive morphology (88.2% versus 27.7%) compared with dilatation patterns (11.8% versus 72.3%; P<0.001) of iVAD. The ischemic presentation was significantly associated with e+iVAD (iVAD as a reference; adjusted odds ratio, 3.97 [95% CI, 1.67-9.45]; P=0.002]). Patients with unruptured VAD showed no differences in the rate of composite clinical outcome between the groups (log-rank, P=0.996). e+iVAD had a lower intracranial remodeling index (1.4±0.3 versus 1.6±0.4; P<0.032) and a shorter distance from dural entry to the maximal dissecting segment (6.9±8.4 versus 15.7±7.4; P<0.001). CONCLUSIONS: e+iVAD is associated with lower rates of hemorrhages and higher rates of ischemia than iVAD at the time of admission. This may be explained by a lower intracranial remodeling index and less deep intrusion of the dissecting segment into the intracranial space.

RESUMEN

INTRODUCTION: Vertebral artery injury (VAI) following blunt trauma can lead to acute or delayed life-threatening posterior fossa ischemic stroke. Its management raises controversial issues and is still open to debate. MATERIAL & METHOD: We report the case of a 48-year-old male who presented a life-threatening posterior circulation ischemic stroke, secondary to a vertebral artery dissection caused by a cervical spine fracture. This case was successfully managed through intravenous thrombolysis and endovascular thrombectomy followed by antiplatelet therapy and an anterior cervical discectomy and fusion. At the one-year follow-up, the patient had no persisting deficit and was back working as a policeman. CONCLUSION: Rapid management of patients with dramatic clinical presentation can lead to full recovery. Implications include a systematic screening of blunt trauma VAI through computed tomography angiography when dealing with high-risk cervical spine fractures; patients harboring both a cervical spine fracture and a VAI must be transferred to a tertiary referral hospital able to deal both with strokes and cervical spine surgery to ensure responsiveness in case of stroke.

RESUMEN

Spontaneous spine epidural haematoma is a rare occurrence, with an incidence of 0.1/100 000 inhabitants/year. The anterior location of the haematoma is very uncommon since the dural sac is firmly attached to the posterior longitudinal ligament. Vertebral artery dissection as its underlying cause is an exceptionally rare event, with only two documented cases.This article presents the case of young woman who arrived at the emergency room with a spinal ventral epidural haematoma extending from C2 to T10, caused by a non-traumatic dissecting aneurysm of the right vertebral artery at V2-V3 segment. Since the patient was tetraparetic, she underwent emergent laminectomy, and the vertebral artery dissection was subsequently treated endovascularly with stenting.Vertebral artery dissection with subsequent perivascular haemorrhage is a possible cause of spontaneous spine epidural haematoma, particularly when located ventrally in the cervical and/or high thoracic column. Hence the importance of a thorough investigation of the vertebral artery integrity.
