RESUMEN

OBJECTIVE: Venous thoracic outlet syndrome (vTOS) is caused by compression of the subclavian vein at the costoclavicular space, which may lead to vein thrombosis. Current treatment includes thoracic outlet decompression with or without venolysis. However, given its relatively low prevalence, the existing literature is limited. Here, we report our single-institution experience in the treatment of vTOS. METHODS: We performed a retrospective review of all patients who underwent rib resection for vTOS at our institution from 2007 to 2022. Demographic, procedural details, and perioperative and long-term outcomes were reviewed. RESULTS: A total of 76 patients were identified. The mean age was 36 years. Swelling was the most common symptom (93%), followed by pain (6.6%). Ninety percent of patients had associated deep vein thrombosis, with 99% of these patients starting anticoagulation preoperatively. A total of 91% of patients underwent rib resection via the infraclavicular approach, 2% via the paraclavicular approach (due to a neurogenic component), and 7% via the transaxillary approach. Eighty-three percent of patients had endovascular intervention before or at the time of the rib resection, with catheter-directed thrombolysis (87%), followed by angioplasty (71%) and rheolytic thrombectomy (57%) being the most common interventions. The median time from endovascular intervention to rib resection was 14 days, with 25% at the same admission. The median postoperative stay was 3 days (2-5 days). There was no perioperative mortality or nerve injury. Fourteen percent of patients had postoperative complications, with bleeding complications (12%) being the most common. Waiting more than 30 days between initial endovascular intervention and rib resection was not associated with decreased risk of bleeding complications. Patients were seen postoperatively at 1-month (physical examination) and 6-month (duplex) intervals or for any new or recurrent symptoms. Twenty-two percent of our overall patient population underwent reintervention, most commonly angioplasty (21%). At last follow-up, 97% of subclavian veins were patent, and 93% of patients were symptom free. CONCLUSIONS: Over the last decade, we have transitioned to an infraclavicular approach for isolated vTOS, with low perioperative morbidity and good patency rates. These results support the adoption of the infraclavicular approach with adjunct endovascular techniques as a safe and efficacious treatment of vTOS.

RESUMEN

We present a case of venous thoracic outlet syndrome involving upper extremity venous thrombosis confirmed by hyperabduction during balloon inflation in the subclavian vein. This provocative test provides clear evidence of extrinsic venous compression, confirming venous thoracic outlet syndrome.

RESUMEN

BACKGROUND: We evaluated the impact of completion intraoperative venography on clinical outcomes for axillosubclavian vein (AxSCV) thrombosis owing to venous thoracic outlet syndrome (vTOS). METHODS: We performed a retrospective, single-center review of all patients with vTOS treated with first rib resection (FRR) and intraoperative venography from 2011 to 2023. We reviewed intraoperative venographic films to classify findings and collected demographics, clinical and perioperative variables, and clinical outcomes. Primary end points were symptomatic relief and primary patency at 3 months and 1 year. Secondary end points were time free from symptoms, reintervention rate, perioperative complications, and mortality. RESULTS: Fifty-one AxSCVs (49 patients; mean age, 31.3 ± 12.6 years; 52.9% female) were treated for vTOS with FRR and external venolysis followed by completion intraoperative venography with a mean follow up of 15.5 ± 13.5 months. Before FRR, 32 underwent catheter-directed thrombolysis (62.7%). Completion intraoperative venography identified 16 patients with no stenosis (group 1, 31.3%), 17 with no stenosis after angioplasty (group 2, 33.3%), 10 with residual stenosis after angioplasty (group 3, 19.7%), and 8 with complete occlusion (group 4, 15.7%). The overall symptomatic relief was 44 of 51 (86.3%) and did not differ between venographic classifications (group 1, 14 of 16; group 2, 13 of 17; group 3, 10 of 10; and group 4, 7 of 8; log-rank test, P = .5). The overall 3-month and 1-year primary patency was 42 of 43 (97.7%) and 32 of 33 (97.0%), respectively (group 1, 16 of 16 and 9 of 9; group 2, 16 of 17 and 12 of 13; group 3, 10 of 10, 5 of 5; group 4, primary patency not obtained). There was one asymptomatic rethrombosis that resolved with anticoagulation, and three patients underwent reintervention with venous angioplasty for significant symptom recurrence an average 2.89 ± 1.7 months after FRR. CONCLUSIONS: Our single-center retrospective study demonstrates that FRR with completion intraoperative venography has excellent symptomatic relief and short- and mid-term patency despite residual venous stenosis and complete occlusion. Although completion intraoperative venographic classification did not correlate with adverse outcomes, this protocol yielded excellent results and provides important clinical data for postoperative management. Our results also support a conservative approach to AxSCV occlusion identified after FRR.

RESUMEN

OBJECTIVE: Surgical decompression via transaxillary first rib resection (TFRR) is often performed in patients presenting with venous thoracic outlet syndrome (VTOS). We aimed to evaluate the outcomes of TFRR based on chronicity of completely occluded axillosubclavian veins in VTOS. METHODS: We performed a retrospective institutional review of all patients who underwent TFRR for VTOS and had a completely occluded axillosubclavian vein between 2003 and 2022. Patients were categorized into three groups based on the time of inciting VTOS event to TFRR acuity of their venous occlusion: <4 weeks, 4 to 12 weeks, and >12 weeks. We evaluated the association of TFRR timing with 1-year outcomes, including patency and symptomatic improvement. We used the χ2 test to compare baseline characteristics and postoperative outcomes. RESULTS: Overall, 103 patients underwent TFRR for VTOS with a completely occluded axillosubclavian vein (median age, 30.0 years; 42.7% female; 8.8% non-White), of whom 28 had occlusion at <4 weeks, 36 had occlusion at 4 to 12 weeks, and 39 had occlusion at >12 weeks. Postoperative venogram performed 2 to 3 weeks after TFRR demonstrated that 78.6% in the <4 weeks group, 72.2% in the 4- to 12-weeks group, and 61.5% in the >12 weeks group had some degree of recanalization (P = .76). Postoperative balloon angioplasty was successfully performed in 60 patients with stenosed or occluded axillosubclavian vein at the time of postoperative venogram. At the 10- to 14-month follow-up, 79.2% of the <4 weeks group, 73.3% of the 4- to 12-weeks group, and 73.3% of the >12 weeks group had patent axillosubclavian veins based on duplex ultrasound examination (P = .86). Among patients who underwent postoperative balloon angioplasty, 80.0%, 85.0% and 100% in the <4 weeks, 4- to 12-weeks, and >12 weeks groups respectively demonstrated patency at 10 to 14 months (P = .31). Symptomatic improvement was reported in 95.7% in the <4 weeks group, 96.7% in the 4- to 12-weeks group, and 93.5% in the >12 weeks group (P = .84). CONCLUSIONS: TFRR offers excellent postoperative outcomes for patients with symptomatic VTOS, even in cases of completely occluded axillosubclavian veins, regardless of the chronicity of the occlusion. By 14 months, 95.2% of patients experienced symptomatic improvement, and 75% attained venous patency.

RESUMEN

Venous thoracic outlet syndrome (vTOS) is an esoteric condition that presents in young, healthy adults. Treatment includes catheter-directed thrombolysis, followed by first-rib resection for decompression of the thoracic outlet. Various techniques for first-rib resection have been described with successful outcomes. The infraclavicular approach is well-suited to treat the most medial structures that are anatomically relevant for vTOS. A narrative review was conducted to specifically examine the literature on infraclavicular exposure for vTOS. The technique for this operation is described, as well as the advantages and disadvantages of this approach. The infraclavicular approach is a reasonable choice for definitive treatment of uncomplicated vTOS.

RESUMEN

Venous thoracic outlet syndrome (vTOS) is an increasingly recognized diagnosis in young patients in which the subclavian vein is compressed within the costoclavicular space. With repetitive compression, thrombosis can develop and has been referred to as "effort thrombosis" or the Paget-Schroetter syndrome. Here, we present a 16-year-old boy with vTOS who presented with acute ischemic stroke (AIS) in the hand knob region of precentral gyrus due to paradoxical embolus in the setting of atrial septal defect.

RESUMEN

BACKGROUND: Current management of axillosubclavian deep venous thrombosis (DVT) often uses thrombolysis for the DVT, prompt first rib removal, and occasional venoplasty or stenting. Our institution has increasingly used anticoagulation alone followed by interval first rib resection. We sought to analyze the effectiveness of this simplified technique. METHODS: Between September 2012 and April 2021, 27 patients were identified within the institution's electronic medical record as having undergone first rib resection for upper extremity DVT. Seven of these patients had undergone preoperative thrombolysis before referral and were excluded. Among the remaining 20 patients, preoperative clinic charts were evaluated for age, venous segment involvement, contralateral limb involvement, presence of documented hypercoagulable state, duration of preoperative and postoperative anticoagulation, and postoperative outcomes. RESULTS: Of the 20 patients (mean age, 26.2 years; 13 males) presenting with acute axillosubclavian DVT, all patients had right (n = 8) or left (n = 12) arm swelling. Five patients had extremity pain and four had extremity discoloration. Ten had axillosubclavian vein involvement, 9 had subclavian vein involvement, and 1 had axillary vein involvement. Two patients were on oral contraceptives and no patients had any other diagnosed hypercoagulable conditions. The mean duration of preoperative and postoperative anticoagulation was 3.2 ± 2.6 months and 2.1 ± 2.1 months, respectively. Nineteen patients underwent supraclavicular first rib resection and 1 patient underwent transaxillary resection. Twelve patients (60%) demonstrated complete DVT resolution by venous duplex examination during the postoperative period and 8 patients (40%) demonstrated partial recanalization/chronic DVT. Complications included one hemothorax and one thoracic duct injury. All 20 patients remain asymptomatic without arm swelling, with a mean follow-up of 55.1 ± 34.7 months. CONCLUSIONS: Among patients presenting with acute axillosubclavian DVT, anticoagulation alone followed by interval first rib resection proved to be successful in providing symptomatic relief in the short to medium term. By eliminating the need for preoperative thrombolysis and postoperative venograms, this potentially cost-saving algorithm simplifies our management for acute venous thoracic outlet syndrome while maintaining good clinical outcomes. Because this study only analyzed our management algorithm's effectiveness in the short to medium term, the long-term effectiveness of this treatment will need to be demonstrated.

RESUMEN

Approximately 3% of all patients presenting with Thoracic Outlet Syndrome have a venous etiology (vTOS), which is considered "effort thrombosis". These patients will present with symptomatic deep venous thrombosis or focal subclavian vein (SCV) stenosis. Endovascular management of vTOS occurs in several phases: diagnostic, preoperative therapeutic intervention before decompression, postoperative interventions after decompression, and delayed interventions in the follow-up after decompression. In the diagnostic phase, dynamic SCV venography can establish functional vTOS. Approximately 4,000 patients have been treated for vTOS and reported in the literature since 1970. Declotting of the SCV was followed by surgical decompression in 53% of patients, while in the remainder, surgical decompression alone (18%), endovascular intervention alone (15%), or conservative therapy with anticoagulation (15%) was performed. The initial intervention was predominantly catheter-directed thrombolysis, with <10% of cases undergoing concomitant balloon angioplasty. 93% of cases were successful. In the postoperative phase, balloon angioplasty was performed to correct residual intrinsic SCV disease after vTOS decompression in under 15% of cases. Stents were rarely deployed. Symptom relief was reported as 94 ± 12% (mean ± SD) and 90 ± 23%, respectively for declotting with decompression and declotting alone. In the delayed phase, balloon angioplasty was performed in under 15% of cases to re-establish patency.

RESUMEN

Paget-Schroetter syndrome is the primary thrombotic event associated with venous thoracic outlet syndrome. It needs to be suspected when encountering localized brachial swelling and a dilated vein in patients with a history of upper limb exercise.

RESUMEN

INTRODUCTION AND IMPORTANCE: The thoracic outlet syndrome is characterized by compression of the brachial plexus or subclavian vessels due to anatomical alterations of the thoracic cavity. Vascular presentation is rare and includes thromboembolism and edema in the upper limb, and the diagnosis is often elusive due to its rarity. In this case, we describe a vascular thoracic outlet syndrome presentation whose diagnosis through angiography was achieved after a mechanical thrombectomy. CASE PRESENTATION: We report a 43-year-old female patient with pain in the right upper limb, accompanied by edema and mild violet discoloration, without risk factors for hypercoagulability, with D-dimer levels within normal values. Mechanical thrombectomy with AngioJET was performed via an endovascular approach, with the extraction of multiple clots, confirming the presence of thoracic outlet syndrome as the underlying cause of the current condition. CLINICAL DISCUSSION AND CONCLUSIONS: Venous thoracic outlet syndrome is a challenging entity to diagnose; however, it should be considered in cases of deep vein thrombosis of the subclavian vein and confirmed by angiography after a thrombectomy.

RESUMEN

Venous compression syndromes have been described, yet the role of sex is poorly understood. Although iliac vein compression has been discussed more often with the advent of newer technologies, research has fallen short on defining epidemiology, best practices for evaluation and treatment, and differences in responses to treatment between men and females. The authors report on iliac vein compression, nonthrombotic renal vein compression, and other venous compression syndromes in females. Literature searches of PubMed were performed using the following keywords: females/females and May Thurner, venous stenting, venous outcomes, deep venous disease, deep venous compression, venous stenting, renal vein compression, renal vein surgery/stent, popliteal vein entrapment, venous thoracic vein entrapment, and popliteal vein entrapment. The articles prompted the authors to research further as the referenced articles were reviewed. Sex representation has not been addressed adequately in the research of venous compression syndromes, making the discussion of best treatment options and long-term outcomes difficult. More specific understanding of epidemiology and response to interventions will only come from research that addresses these issues directly, understanding that some of these syndromes occur rarely.

RESUMEN

Thoracic outlet syndrome (TOS) involves the compression of neurovascular structures in the thoracic outlet. TOS subtypes, including neurogenic (nTOS), venous (vTOS), and arterial (aTOS) are characterized by distinct clinical presentations and diagnostic considerations. This review explores the incidence, diagnostic challenges, and management of TOS with a focus on the innovative approach of Robotic First Rib Resection (R-FRR). Traditional management of TOS includes conservative measures and surgical interventions, with various open surgical approaches carrying risks of complications. R-FRR, a minimally invasive technique, offers advantages such as improved exposure, reduced injury risk to neurovascular structures, and shorter hospital stays. A comprehensive literature review was conducted to assess the outcomes of R-FRR for TOS. Data from 12 selected studies involving 397 patients with nTOS, vTOS, and aTOS were reviewed. The results indicate that R-FRR is associated with favorable intraoperative outcomes including minimal blood loss and low conversion rates to traditional approaches. Postoperatively, patients experienced decreased pain, improved function, and low complication rates. These findings support R-FRR as a safe and effective option for medically refractory TOS.

RESUMEN

OBJECTIVE: Currently, there is no consensus on the optimal management of Paget-Schroetter syndrome (PSS). The objective was to summarise the current evidence for management of PSS with explicit attention to the clinical outcomes of different management strategies. DATA SOURCES: The Cochrane, PubMed, and Embase databases were searched for reports published between January 1990 and December 2021. REVIEW METHODS: A systematic review and meta-analysis was conducted following PRISMA 2020 guidelines. The primary endpoint was the proportion of symptom free patients at last follow up. Secondary outcomes were success of initial treatment, recurrence of thrombosis or persistent occlusion, and patency at last follow up. Meta-analyses of the primary endpoint were performed for non-comparative and comparative reports. The quality of evidence was assessed using the GRADE approach. RESULTS: Sixty reports were included (2 653 patients), with overall moderate quality. The proportions of symptom free patients in non-comparative analysis were: anticoagulation (AC), 0.54; catheter directed thrombolysis (CDT) + AC, 0.71; AC + first rib resection (FRR), 0.80; and CDT + FRR, 0.96. Pooled analysis of comparative reports confirmed the superiority of CDT + FRR compared with AC (OR 13.89, 95% CI 1.08 - 179.04; p = .040, I2 87%, very low certainty of evidence), AC + FRR (OR 2.29, 95% CI 1.21 - 4.35; p = .010, I2 0%, very low certainty of evidence), and CDT + AC (OR 8.44, 95% CI 1.12 - 59.53; p = .030, I2 63%, very low certainty of evidence). Secondary endpoints were in favour of CDT + FRR. CONCLUSION: Non-operative management of PSS with AC alone results in persistent symptoms in 46% of patients, while 96% of patients managed with CDT + FFR were symptom free at end of follow up. Superiority of CDT + FRR compared with AC, CDT + AC, and AC + FRR was confirmed by meta-analysis. The overall quality of included reports was moderate, and the level of certainty was very low.

RESUMEN

The subclavian vein is typically used in cardiovascular implantable electronic device (CIED) implantations. External stress on the subclavian vein can lead to lead-related complications. There are several causes of this stress, such as frequent upper extremity movements or external injury. Venous thoracic outlet syndrome (TOS) can also become the cause of external lead stress. However, the diagnosis of venous TOS can be challenging because subclavian venography can appear normal at first glance. We present a unique case of a device infection in a patient with venous TOS. A careful observation of the imaging studies is vital for diagnosing venous TOS and a leadless pacemaker implantation could be an alternative therapeutic option.

RESUMEN

McCleery syndrome is a rare form of venous thoracic outlet syndrome characterized by intermittent obstruction of the subclavian vein (SCV) without thrombosis. In 2022, two patients presented to our clinic with McCleery syndrome after living with venous symptoms for over one year. Duplex scans of both patients revealed compression of the SCV on abduction. A first rib resection and anterior scalenectomy were performed to decompress the SCV. At two weeks post-op, a follow-up venogram revealed widely patent, unobstructed SCVs in both patients.

RESUMEN

Upper extremity deep vein thrombosis (UEDVT) is responsible for 4 to 10% of all deep vein thrombosis (DVT). Untreated UEDVT can lead to significant disability secondary to the postthrombotic syndrome. To date, there are no randomized trials specifically comparing different therapeutic strategies. Ultimately, optimal management of UEDVT depends on the underlying etiology, patient symptoms, and degree of thrombosis, with supporting evidence primarily extrapolated from lower extremity DVT data. This article will review the classification, presentation, and diagnosis of both primary and secondary UEDVT. In addition, it will discuss updates in clinical guidelines, anticoagulation, endovascular and surgical treatment strategies.

RESUMEN

BACKGROUND: Clinicians trained in point-of-care ultrasound (POCUS) use the tool to enhance diagnostic capabilities at the bedside, often excluding or diagnosing conditions that are suspected based on the history and physical examination. Thoracic outlet syndrome (TOS) involves compression of arteries and nerves between the clavicle and first rib causing pain and paresthesia in the affected limbs. To our knowledge, use of POCUS to diagnose TOS in the literature has not been described. CASE REPORT: A 46-year-old man presented with left upper extremity (LUE) edema, pain, and paresthesia, which was progressive over 3 weeks. Examination of the LUE revealed diffuse swelling without erythema and a left radial pulse present on Doppler only. A subsequent POCUS examination of the LUE was performed to exclude a deep vein thrombosis, and enlarged and turbulent veins distal to the internal jugular vein were found, which suggested venous compression external to the veins. Additional imaging confirmed narrowing of the subclavian vein and a diagnosis of venous thoracic outlet syndrome (vTOS) was made. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Failure to promptly diagnose and treat TOS can lead to long-term chronic upper extremity pain and even permanent disability. Diagnosis of vascular TOS is often made using computed tomography to identify impinged vessels, although color Doppler sonography can be an excellent choice for initial imaging in patients with suspected vTOS. Although POCUS is being used increasingly as a diagnostic tool and for procedural guidance, our case represents a novel application of POCUS in the diagnosis of vTOS.

RESUMEN

Analgesia for first rib resection can be challenging with short- and long-term consequences for patients such as acute distress, difficulty participating in physiotherapy and chronic pain. We report utilising an erector spinae plane block with a continuous infusion catheter as analgesia for a transaxillary first rib removal in a patient with venous thoracic outlet syndrome (Paget-Schroetter syndrome). We could find no reports of erector spinae plane block in transaxillary rib resection, and a limited number of reports using a paravertebral approach to analgesia for this procedure. In our case, an erector spinae plane block provided effective analgesia, allowing the patient to participate freely in postoperative physiotherapy; no complications of erector spinae plane block were encountered. Further research into the safety and efficacy of erector spinae plane block for first rib resection is warranted.

RESUMEN

PURPOSE: In Paget-Schroetter Syndrome (PSS), subclavian vein thrombosis is caused by external compression of the subclavian vein at the costoclavicular junction. Paget-Schroetter Syndrome can be treated nonoperatively, surgically, or with a combination of treatments. Nonoperative management consists, in most cases, of anticoagulation (AC) or catheter-directed thrombolysis (CDT). With surgical management, decompression of the subclavian vein is performed by resection of the first rib. No prospective randomized trials are available to determine whether nonoperative or surgical management is superior. We report our long-term outcomes of both nonoperative and surgically treated patients. MATERIALS AND METHODS: We retrospectively analyzed all patients with PSS who were treated between January 1990 and December 2015. Patients were divided based on primary nonoperative or primary surgical therapy. Long-term outcomes regarding functional outcomes were assessed by questionnaires using the "Disability of the Arm, Shoulder, and Hand" (DASH) questionnaire, a modified Villalta score, and a disease-specific question regarding lifestyle changes. RESULTS: In total, 91 patients (95 limbs) were included. Seventy patients (73 limbs) were treated nonoperatively and 21 patients (22 limbs) surgically. Questionnaires were returned by 67 patients (70 limbs). The mean follow-up was 184 months (range, 43-459 months). All functional outcomes were better in the surgical group compared with the nonoperatively treated group (DASH general 3.11 vs 9.86; DASH work 0.35 vs 11.47; DASH sport 5.85 vs 17.98, and modified Villalta score 1.11 vs 3.20 points). Surgically treated patients were more likely to be able to continue their original lifestyle and sports activities (84% vs 40%, p=0.005). Patients with recurrence of thrombosis or the need for surgical intervention after primary nonoperative management reported worse functional outcomes. CONCLUSION: Surgical management of PSS with immediate CDT followed by first rib resection leads to excellent functional outcomes with low risk of complications. The results of nonoperative management in our non-matched retrospective comparative series were satisfactory, but resulted in worse functional outcomes and more patients needing to adjust their lifestyle compared with surgically treated patients. CLINICAL IMPACT: Patients with Paget-Schroetter Syndrome and their attending physicians are burdened by the lack of evidence concerning the optimal treatment of this entity. Case series comparing the outcomes of non-operative treatment with surgical treatment are scarce and often not focussed on functional outcomes. Data from this series can aid in the shared decision making after diagnosis of Paget-Schroetter Syndrome. Functional outcomes of non-operative management can be satisfying although high demand patient who are not willing to alter their daily activities are probably better off with surgical management.

RESUMEN

Current methodologies of diagnosing and managing venous thoracic outlet syndrome (vTOS) remain controversial, as pertinent studies using modern advancements in medicine are limited. We present a case in which we innovatively used a modified Wright's test during venography coupled with intravascular ultrasound, which allowed us to definitively determine the etiology of a vTOS. (Level of Difficulty: Intermediate.).
