RESUMEN

Venous aneurysms of the external jugular vein are rare vascular anomalies due to the low pressure in the venous circulation i.e. the superior vena cava. A review of the literature reveals that external jugular vein aneurysms are reported rarely but the exact incidence of such aneurysms is not known. The presentation of external jugular vein aneurysms can vary widely but generally, they present as a soft cervical mass which gradually increases in size. These aneurysms pose a diagnostic and management challenge for the clinician as their clinical spectrum ranges from being asymptomatic, to cosmetic concerns or they can potentially cause thrombosis, embolism, or thrombophlebitis. Diagnosis is confirmed via Color Doppler ultrasound and computerized tomogram angiography. We present the clinical features and diagnosis of a saccular external jugular vein pseudoaneurysm in a 58-year-old female, which was most likely to be congenital and was diagnosed using computerized tomogram angiography.

RESUMEN

Neurological long Covid (NLC) is a major post-acute sequela of SARS-CoV-2 infection, affecting up to 10% of infected patients. The clinical presentation of patients with NLC is varied, but general NLC symptoms have been noted to closely mimic symptoms of cerebral venous outflow disorders (CVD). Here we review key literature and discuss evidence supporting this comparison. We also aimed to describe the similarity between CVD symptomatology and neuro-NLC symptoms from two perspectives: a Twitter-distributed survey for long covid sufferers to estimate nature and frequency of neurological symptoms, and through a small cohort of patients with long covid who underwent CVD work up per our standard workflow. Over 700 patients responded, and we argue that there is a close symptom overlap with those of CVD. CVD workup in a series of 6 patients with neurological long COVID symptoms showed jugular vein stenosis by CT venography and varying degrees of increased intracranial pressure. Finally, we discuss the potential pathogenic association between vascular inflammation, associated with COVID-19 infection, venous outflow congestion, and its potential involvement in NLC.

RESUMEN

OBJECTIVE: The arterial wall not only moves in the radial direction to expand circumferentially but also moves in the axial (longitudinal) direction in a predictable bidirectional pattern during a normal cardiac cycle. While common carotid artery (CCA) longitudinal wall motion (CALM) has been described previously, there is a lack of evidence-based method standardization to align practices for human measurement. The purpose of this study was to evaluate whether different scanning planes impact CALM outcomes in healthy males and females to provide clarity on data collection strategies. METHODS: Thirty-one healthy adults (16 females, 23 ± 3 y of age) underwent ultrasound scanning of the right CCA in the anterior, lateral, and posterior imaging planes. CALM was evaluated using a custom speckle-tracking algorithm and was analyzed as segmental motion outcomes (anterograde, retrograde, maximum displacement and radial-axial path length). RESULTS: No differences in any CALM outcome were observed between imaging planes (p > 0.05), and equivalence testing indicated that retrograde CALM displacement was similar between anterior and posterior distal walls (p = 0.04). We observed no differences (p > 0.05) in CALM outcomes between the proximal (free-wall, adjacent to the internal jugular vein [IJV]) and distal wall in the posterior imaging plane. Qualitatively, it was more difficult to successfully track vascular tissue between the IJV and CCA due to the thin wall components and highly mobile wall in the radial direction. CONCLUSION: In the absence of clear differences between scanning planes, we recommend standardizing acquisition in the lateral plane and avoiding the IJV free-wall when evaluating CALM in humans.

RESUMEN

Background: Central venous catheterization by anesthesiologists carries risks such as accidental arterial puncture. This case report highlights a rare subclavian artery aneurysm (SAA) detected during ultrasound-guided internal jugular vein (IJV) access, emphasizing the importance of recognizing anatomical variations. Case: An 88-year-old female with hypertension and atrial fibrillation was scheduled for lumbar laminectomy and posterior fusion. Preoperative evaluation revealed right lower lobe atelectasis and mild aortic sclerosis. During ultrasonography for right IJV catheterization, two vessels of different diameters were observed on the common carotid artery's (CCA's) lateral side. The larger vessel disappeared at the upper neck level, showing arterial pulsation on Color Doppler. Postoperative neck computed tomography confirmed a right SAA and a 5-mm saccular aneurysm in the left intracranial artery. The patient had no vascular disease, trauma, or relevant family histories. Conclusions: Anesthesiologists should be aware of anatomical variations during IJV catheterization. Ultrasound with Doppler is crucial for accurate artery identification.

RESUMEN

Central venous catheter (CVC) placement is a routine procedure in ICUs but can be associated with various complications, including misplacement and thrombosis. We present a rare case of parotid gland enlargement due to catheter-related thrombosis of the external jugular vein following ultrasound-guided placement through the subclavian vein in an 84-year-old woman. This case was managed with systemic anticoagulation and catheter removal. It emphasizes the importance of confirming correct CVC tip positioning and highlights the need for a post-procedure chest X-ray.

RESUMEN

BACKGROUND: External Jugular Thrombophlebitis (EJT) is a rare clinical phenomenon with few reports in the literature, especially in the pediatric population. This is a report of an unusual case of right-sided EJT in a pediatric patient secondary to acute pharyngitis with sinusitis most prominent on the left side. CASE PRESENTATION: A 13-year-old presented to the emergency department with worsening upper respiratory infectious (URI) symptoms and facial swelling, cough, throat pain, and emesis. The patient had traveled to Switzerland and received amoxicillin for strep throat 6 weeks before this hospitalization. Physical examination revealed nasal purulence, allodynia over the right side of the face without overlying erythema, and oropharyngeal exudate. CT scan revealed left-sided predominate sinusitis and right external jugular vein thrombosis. Blood cultures confirmed the presence of group A streptococcus infection. Treatment included IV antibiotics, non-steroidal anti-inflammatory drugs (NSAIDs), IV steroids, and anticoagulation. Follow-up imaging demonstrated improvement in thrombosis, cellulitis, and sinus disease. The patient was discharged on antibiotics for 6 weeks and anticoagulation for 10 weeks. Follow-up imaging at 6 months revealed no EJT, and medications were discontinued. CONCLUSIONS: EJT is a rare condition, and to our knowledge, no reports of EJT with sinusitis most pronounced on the contralateral side have been published. Physicians will benefit from noting clinical signs of EJT such as facial edema, headache, erythema, and palpable neck mass, especially if these symptoms occur with URI symptoms refractory to treatment. The use of anticoagulation is controversial for internal jugular vein thrombosis, and while no guidelines for EJT exist, anticoagulation is likely not necessary save for severe complications.

RESUMEN

BACKGROUND: The internal jugular vein (IJV) plays a major role in collecting venous blood from the cranium, face, and neck. Preserving or reconstructing at least one IJV during bilateral radical neck dissection (RND) allows preventing severe complications. The aim of this report was to present a variant of IJV reconstruction in bilateral radical neck dissection. CASE SUMMARY: A 55-year-old male complained for a gingival mass for about 2 months, which was approximately 4 × 2 cm in size with a surface ulceration, located in the anterior mandibular area. There were bilateral cervical adenopathy. The computed tomography (CT) scan revealed mandibular bone destruction with surrounding soft tissue masse, multiple enlarged lymph nodes around bilateral submandibular space and bilateral carotid sheath, with obvious necrosis in the center. The preoperative diagnosis was mandibular gingiva squamous cell carcinoma (SCC), staged T4aN2bM0. Under general anesthesia, the patient underwent bilateral RND with sacrifice of right IJV and reconstruction of left IJV by anastomosis of IJV to the ipsilateral EJV using the common facial vein as a communicating way, followed by an expanded resection of mandibular gingiva SCC via marginal mandibulectomy, left anterolateral thigh (ALT) free flap reconstruction of the resulting defects, and tracheotomy. The patient's post-operative course was uneventfully. CONCLUSION: In our case report, the immediate IJV reconstruction by the W method was performed without compromising oncologic principles and was found feasible, safe and effective to prevent the occurrence of severe postoperative complications related to bilateral RND with sacrifice of both IJV.

RESUMEN

Chronic kidney disease has become a significant global health issue, with some individuals progressing to endstage renal disease (ESRD) and requiring renal replacement therapy. For ESRD patients undergoing haemodialysis, the first step is to establish vascular access. In emergency situations, inserting a haemodialysis catheter (HDC) into the central vein is often the most appropriate approach; the right internal jugular vein (IJV) is considered the optimal site for catheterisation. However, catheter placement in the right IJV can sometimes lead to inadvertent entry into an abnormal position. Herein, we present a unique case in which the tip of the HDC was noted to have misplaced into the left IJV due to the patient's multiple central venous stenosis (CVS). This case highlights the clinical manifestation of HDC misplacement, with CVS being the underlying cause. Therefore, healthcare providers should pay adequate attention to CVS.

RESUMEN

Neurofibromatosis Type 1 (NF1) is a rare autosomal dominant disorder that has a wide array of clinical manifestations. NF1 Vasculopathies constitute 0.4% to 6.4% of the findings and they often develop in the arterial circulation while venous involvement is rare. We present a case of a 73-year-old male with NF1 with an incidental finding of right neck swelling for 2 months. Different radiological modalities were performed, identifying the lesion as an internal jugular vein aneurysm. The patient was managed conservatively as he was asymptomatic in relation to the swelling. NF1 venous vasculopathies are rare but they have detrimental consequences such as rupture and severe hemorrhage in view of the fragility of the aneurysmal wall and the infiltration of the neurofibroma into the vessel. Hence, high clinical suspicion and selective imaging and follow-up is advisable for physicians.

RESUMEN

Aneurysms of the external jugular vein (EJV) are uncommon vascular malformations. Due to their rarity, it is currently unclear what the risk of complications are and whether surgical management should be offered. The risks associated with the surgery need to be balanced with the risk of complications from the malformation. We present the case of a young woman who presented with a painful erythematous neck swelling who was found to have an aneurysm of the EJV with thrombophlebitis. This was successfully treated with surgical excision. We discuss current evidence for treatment of neck vein aneurysms and pitfalls.

RESUMEN

In spite of expanding research, idiopathic intracranial hypertension (IIH) and its spectrum conditions remain challenging to treat. The failure to develop effective treatment strategies is largely due to poor agreement on a coherent disease pathogenesis model. Herein we provide a hypothesis of a unifying model centered around the internal jugular veins (IJV) to explain the development of IIH, which contends the following: (1) the IJV are prone to both physiological and pathological compression throughout their course, including compression near C1 and the styloid process, dynamic muscular/carotid compression from C3 to C6, and lymphatic compression; (2) severe dynamic IJV stenosis with developments of large cervical gradients is common in IIH-spectrum patients and significantly impacts intracranial venous and cerebrospinal fluid (CSF) pressures; (3) pre-existing IJV stenosis may be exacerbated by infectious/inflammatory etiologies that induce retromandibular cervical lymphatic hypertrophy; (4) extra-jugular venous collaterals dilate with chronic use but are insufficient resulting in impaired aggregate cerebral venous outflow; (5) poor IJV outflow initiates, or in conjunction with other factors, contributes to intracranial venous hypertension and congestion leading to higher CSF pressures and intracranial pressure (ICP); (6) glymphatic congestion occurs but is insufficient to compensate and this pathway becomes overwhelmed; and (7) elevated intracranial CSF pressures triggers extramural venous sinus stenosis in susceptible individuals that amplifies ICP elevation producing severe clinical manifestations. Future studies must focus on establishing norms for dynamic cerebral venous outflow and IJV physiology in the absence of disease so that we may better understand and define the diseased state.

RESUMEN

Background: Insertion of electrode catheters into the coronary sinus (CS) through the right internal jugular vein (RIJV) carries risks of pneumothorax and severe hematoma formation. This study was performed to compare the safety and feasibility of catheterization through the left cubital superficial vein versus the RIJV. Methods: This prospective nonrandomized study involved consecutive patients who underwent catheter ablation from September 2021 to February 2023. Blind puncture techniques were used in the left cubital vein group; ultrasound-guided insertion was performed in the RIJV group. The success rates of sheath insertion and CS catheterization, the procedure and fluoroscopy times of CS cannulation, and complications were compared between groups. Results: The left cubital vein group comprised 152 patients, and the RIJV group comprised 58 patients. The sheath insertion success rate was significantly lower in the cubital vein group than in the RIJV group (84.9% vs 100%, respectively; p = .0008). In the cubital vein group, blind puncture attempts failed in 20 patients; three patients developed guidewire-induced venous injury. One arterial puncture occurred in the RIJV group. After successful sheath insertion, no significant differences were observed in the CS cannulation success rate (97% vs 100%, p = .55), procedure time (median [range], 93 [51-174] vs 74 [44-129] s; p = .19), or fluoroscopy time (median [range], 66 [36-134] vs 48 [30-92] s; p = .17). No serious complications requiring procedural discontinuation occurred. Conclusion: The left cubital vein approach is practical, offering a viable alternative to the RIJV approach.

RESUMEN

The use of anticoagulants in Lemierre's syndrome is not well-defined, lacking clear evidence for their efficacy. This report describes a patient with complete occlusion of the internal jugular vein by a thrombus who did not develop expected complications due to the formation of collateral venous channels.

RESUMEN

PURPOSE: Orbital venous malformations (VM) pose challenges in complete resection due to indistinct borders and bleeding proclivity. Current methods for aiding surgical excision of distensible orbital venous malformations are inadequate. We investigated whether external neck compression could facilitate intraoperative distension of venous orbital lesions during surgical excision in patients diagnosed with VM. METHODS: Eighteen patients (8 males and 10 females) diagnosed with distensible venous anomalies were enrolled. Neck compression technology, was employed to distend the lesions before puncture embolization using n-butyl-2-cyanoacrylate glue under general anesthesia. The surgical process, along with preoperative to postoperative changes in ocular symptoms, were recorded. RESULTS: The average surgical duration was 95 min. A mean of 3.41 ml surgical glue was used for embolization. The compression belt maintained pressure at 35-40 mmHg. Total lesion resection was achieved in 12 patients, with 6 patients undergoing subtotal removal not requiring supplementary surgery. Symptoms were entirely alleviated in 17 patients, and signs of distensible lesions during the Valsalva maneuver were absent. One patient underwent secondary surgery for residual eyelid lesions. Minor complications included mild ocular movement restriction, residual subcutaneous induration, transiently increased orbital pressure, and lower lid ectropion in four, three, four, and one patient, respectively. Three patients experienced a mild post-operative visual acuity decrease, although none experienced vision loss. CONCLUSIONS: Direct orbital embolization aided by a jugular vein compression device is safe and demonstrates satisfactory outcomes in orbital varicose vein treatment.

RESUMEN

OBJECTIVES: This report presents a rare anatomical variation, double fenestration of the External jugular vein on the right side. MATERIALS AND METHODS: During the routine dissection of a male cadaver aged 60 years, we observed a unilateral large double fenestration of the External jugular vein on the right side. RESULTS: After its formation from the posterior division of the retromandibular and posterior auricular veins, External jugular vein descended in the posterior triangle of neck. Here, it divided into medial, intermediate, and lateral veins that united again before draining into the subclavian vein. Lateral vein was the largest (7.2 cm) and intermediate and medial veins were measuring 6.4 cm each. Two large fenestrations, measuring 5.8 cm each, arranged like a "double bubble" were seen in the External jugular vein extending from fourth to sixth cervical (C4 to C6) vertebrae. The medial branch of supraclavicular nerve was seen passing superficial to the distal part of External jugular vein. On the left side, the course of External jugular vein showed a standard pattern. CONCLUSION: Surgeons must be acquainted with the varied anatomy of the superficial neck veins to prevent major bleeding during operative procedures, including carotid endarterectomy, flap operations, & central venous catheterisation.

RESUMEN

The external jugular vein (EJV) has been commonly used for clinical procedures in veterinary medicine, while the internal jugular vein (IJV) has been used mainly for research. Limited literature regarding anatomical variants in both EJV and IJV is available. The objectives of this descriptive retrospective study were to identify the number of dogs with variations of the jugular veins in canine patients undergoing CT of the head and neck and characterize these variations. Of 1000 dogs, 193 dogs (19.3%) had anatomical variations. Six types of anatomical variations were identified. The most common Type I was the absence of the linguofacial vein (72.0%, n = 139), with the lingual, facial, and maxillary veins entering the EJV at a common branching point. Type II described a variable course of the EJV and IJV, which in some dogs resulted in the absence of the EJV (14.0%, n = 27). Type III was a variable anastomotic loop formed by the linguofacial or maxillary vein cranial or at the junction of the EJV (4.2%, n = 8). In Type IV, the EJV was either suspected to be aplastic or markedly reduced in diameter compared with the contralateral side just distal to its formation (3.6%, n = 7). Type V was found in only six dogs (3.1%) with unilateral differences in the diameter of the IJV. Six of 193 dogs had a combination of more than one variation (Type VI, 3.1%). Type I was significantly observed more frequently in meso- and dolichocephalic breeds. Type II was significantly observed more frequently in brachycephalic breeds.

RESUMEN

Rationale: Knowledge of the venous systems of the neck is important in microvascular anastomosis as well as to avoid unintended bleeding during neck dissection. Patient Concerns: We present three rare variations of the jugular system of the neck which could have complicated neck dissection. Diagnosis: The first case is of a posterior tributary from an internal jugular vein (IJV). The second case is an IJV with increased diameter of 3 cm and the third case is an aneurysm of the external jugular vein. Treatment: Careful dissection was carried out to avoid complications and to preserve the vessels for microvascular anastomosis. Outcome: No complications were encountered intraoperatively and post-operatively. Take-away Lessons: Variations from normal anatomy should be dealt with caution to avoid complications and to perform surgery precisely and efficiently.

RESUMEN

Background and aims: Prompt assessments and quick replacement of intravascular fluid are critical steps to resuscitate hypovolemic patients. Intravascular volume assessment by direct central venous pressure (CVP) measurement is an invasive, time-consuming, and labor-intensive procedure. Nowadays, bedside ultrasound-guided volume assessment of the internal jugular vein (IJV) or inferior vena cava (IVC) is commonly employed as a proxy for direct CVP.Therefore, we examined the strength of association between CVP and collapsibility index (CI) of the IJV and IVC for evaluating the volume status of critically ill patients. Methods: Bedside USG-guided A-P diameter and cross-sectional area of the right IJV and IVC were measured, and their corresponding collapsibility indices were deduced. The results of the IJV and IVC indices were correlated with CVP. Results: About 60 out of 70 enrolled patients were analyzed. The baseline clinical parameters of patients are shown in Table 1. For CSA and AP diameter, the correlations between CVP and IJV-CI at 0° were r = -0.107 (p = 0.001) and r = -0.092 (p = 0.001). Correlations between CVP and IJV-CI at 30° for CSA and diameter, however, were (r = -0.109, p = 0.001) and (r = -0.117, p = 0.001), respectively. Table 2 depicts the correlation between CVP and IVC-CI r = -0.503, p = 0.001 for CSA and r = -0.452, p = 0.001 for diameter. Conclusion: The IVC and IJV collapsibility indices can be used in place of invasive CVP monitoring to assess fluid status in critically ill patients.

RESUMEN

Lemierre's syndrome, a rare complication of oropharyngeal infections, is characterized by septic thrombophlebitis primarily affecting the internal jugular vein, which can lead to septicemia, thrombotic obstruction, and potential dissemination to distant sites. We present the case of a 54-year-old male with a history of chronic smoking and newly diagnosed laryngeal carcinoma, complicated by Lemierre's syndrome. Initial symptoms included odynophagia, dyspnea, and cervical swelling, with subsequent diagnosis confirming thrombosis of the internal jugular vein via ultrasound, CT, and MRI. Treatment included broad-spectrum antibiotics and anticoagulation, followed by oncological management for the carcinoma. This case underscores the diagnostic challenge posed by concurrent malignancy and highlights the critical role of early recognition and comprehensive treatment involving antibiotics, anticoagulation, and oncological therapy. Multidisciplinary collaboration is crucial for optimizing outcomes in complex cases like this, emphasizing the need for heightened clinical suspicion and prompt intervention involving proper imaging diagnosis, appropriate antibiotic coverage, and timely microbiological recognition for adjustment of antimicrobial therapy.
