Paget-Schroetter Syndrome (PSS) is a form of upper extremity deep vein thrombosis (DVT) caused by the external compression of the subclavian vein at the thoracic outlet. Here we describe a complex PSS case in a 43-year-old female who experienced multiple recurrent DVTs and a right-sided hemothorax following two continuous aspiration thrombectomy procedures and a first rib resection. Rapid and complete symptom resolution was achieved with the InThrill Thrombectomy System (Inari Medical), a novel, thrombolytic-free, percutaneous mechanical thrombectomy device that removed all recurrent acute and subacute thrombus in a single session without significant blood loss.

Intravascular lipomas (IVL) located in the superior vena cava (SVS) are rare benign primary venous tumors with less than 15 cases reported in the literature. We report a case of a 64-year-old woman with IVL of the SVC extending to the right brachiocephalic vein. She was treated successfully using a hybrid procedure which involved endovascular control of the right subclavian vein and surgical approach via median sternotomy followed by mass resection and use of pericardial patch for vein defect closure.

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.

Purpose: Traditional treatment of axillary-subclavian venous thrombosis is resource intensive due to the need for advanced nursing care and increased utilization of intensive care units for thrombolysis procedures. We recently encountered this in the management of 2 patients with effort-induced upper extremity venous thrombosis following COVID-19 infection and offer a treatment paradigm for consideration. Case Reports: A 30-year-old presented with 2 weeks of left upper extremity symptoms following COVID-19 infection. Duplex ultrasound demonstrated axillary-subclavian venous thrombosis and venogram confirmed total occlusion of the axillary and subclavian veins with profuse collaterals around the occlusion. Suction thrombectomy was performed successfully and veins remained patent at 6 month follow up. The patient declined first rib resection and stopped lifting weights. A 16-year-old presented with 4 days of right arm symptoms 1 month after testing positive for COVID-19. Duplex ultrasound revealed acute axillary and subclavian vein thrombosis and she underwent successful thrombectomy followed by balloon angioplasty with improvement in symptoms. Conclusion: The pandemic has strained health care resources such that the treatment of non-life-threatening conditions must be triaged to conserve resources. While axillary-subclavian venous occlusion is usually not life-threatening, timely treatment leads to decreased morbidity and better outcomes. Percutaneous aspiration and thrombectomy without adjunctive thrombolysis may be of benefit in reducing healthcare resource utilization while still achieving good outcomes during the COVID pandemic and beyond.

Objectives: The incidence and prevalence of iatrogenic vascular trauma in the United States is staggering. This has led to the advent and implementation of more efficient and effective vascular repair methods. Although open surgical repair may still be considered gold standard, new endovascular solutions have emerged as other viable options. When using an endovascular approach, proper stent sizing is vital to a successful repair. Methods: We present a case of a traumatic injury and pseudoaneurysm formation at the confluence of the right internal jugular and right subclavian veins during a central line placement. This iatrogenic pseudoaneurysm was treated with endovascular placement of side-by-side stents. A mathematical formula, which we have designated "Matteo's law," was utilized to select properly sized stent grafts to reconstruct the confluence and prevent infolding and endoleaks. Results: After deployment of kissing stents at the confluence of the right internal jugular and right subclavian veins, a venogram was performed, which demonstrated successful exclusion of the pseudoaneurysm and no endoleaks. Clinical follow-up confirms continued wide open flow through the reconstructed venous confluence at 8 months post-procedure. Conclusion: In reconstruction of a venous confluence, selection of properly sized stent grafts is paramount to preventing infolding and endoleaks. Matteo's law states that the circumference of the native receiving vessel must equal the sum of the circumferences of both kissing stent grafts, subtracting the redundant material where the 2 stents interface.

Venous compression syndromes occur due to extrinsic compression causing complications of venous hypertension or venous thrombosis. This review focuses on 4 venous compression syndromes involving the left common iliac vein, subclavian vein, left renal vein, and popliteal vein. Clinical presentation, diagnostic methods, and management options are reviewed. When properly diagnosed and treated, long-term consequences can be avoided. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 67-year-old man with end-stage failure on hemodialysis and with recurrent symptomatic thoracic central vein obstruction (TCVO). Topics mention including application of double chimney techniques using the interwoven self-expanding nitinol stents to treat nonmalignant TCVO, endovascular intervention with balloon angioplasty and venoplasty procedure.

Objective: To evaluate the diagnostic role of venous and arterial duplex scanning in neurogenic thoracic outlet syndrome (NTOS). Methods: Retrospective review of patients who underwent duplex ultrasonography prior to first rib resection and scalenectomy (FRRS) for NTOS from 2005 to 2013. Abnormal scans included ipsilateral compression (IC) with abduction of the symptomatic extremity (>50% change in subclavian vessel flow), contralateral (asymptomatic side) compression (CC) or bilateral compression (BC). Results: A total of 143 patients (76% female, average age 34, range 13-59) underwent bilateral preoperative duplex scanning. Ipsilateral compression was seen in 44 (31%), CC in 12 (8%), and BC in 14 (10%). Seventy-three (51%) patients demonstrated no compression. Patients with IC more often experienced intraoperative pneumothoraces (49% vs. 25%, P < .05) and had positive Adson tests (86% vs. 61%, P < .02). Conclusion: Compression of the subclavian vein or artery on duplex ultrasonography can assist in NTOS diagnosis. Ipsilateral compression on abduction often correlates with Adson testing.

Objectives: Patients presenting with swelling of the upper extremity without thrombosis have McCleery syndrome or intermittent compression of the subclavian vein. The purpose of this study was to determine outcomes in these patients who underwent first rib resection and scalenectomy (FRRS). Methods: Using a prospectively maintained database from 2003 to 2011, patients were retrospectively reviewed for presentation, diagnosis, treatment, and clinical outcomes. Results: Of the patients presenting with venous thoracic outlet syndrome, 19 (11%; 13 F/6 M; mean age 26 [10-44]) presented with intermittent arm swelling, of which 3 were identified as having chronic thrombus. A total of 20 FRRS operations were performed. Conclusions: First rib resection and scalenectomy is effective in relieving symptoms in patients with McCleery syndrome. These patients do not generally need a postoperative venogram unless they experience continuing symptoms. In patients with chronic thrombus, routine postoperative venography at 2 weeks is indicated. Patients can present with intermittent compression if an acute episode of deep vein thrombosis is not aggressively treated. [ABSTRACT FROM AUTHOR]

Objectives: We reviewed our strategies during the last decade for deep vein thrombosis (DVT) of the upper extremity due to thoracic outlet syndrome (TOS) and the lower extremity. Methods: Between 1998 and 2011, we treated 31 patients with 18 subclavian DVTs and 13 iliac DVTs. Management included catheter-directed thrombolysis compared to mechanical thrombolysis (MT; post 2006). Prior to 2006, patients with TOS were treated with total excision of the first rib compared to excision of the anterior half of the rib. Patients were followed up with serial duplex ultrasounds. Results: There was no major morbidity and no mortality in these 31 patients. Three patients developed recurrent DVT but maintained patency after further treatment. Conclusion: Use of MT has led to shorter treatment duration and length of hospital stay. Limiting first rib resection to the anterior half of the rib shortened operative time. Patients requiring stents had excellent long-term patency rates. [ABSTRACT FROM AUTHOR]

To assess the role of postoperative venography in patients treated with first rib resection and scalenectomy (FRRS) for effort thrombosis, a retrospective review was done to evaluate long-term venous patency in 84 patients treated at the Johns Hopkins Medical Institutions. Patients undergo venography 2 weeks postoperatively. If there is >50% stenosis, the subclavian vein is dilated and the patient receives anticoagulation. If the vein is occluded, patients are maintained on anticoagulation. Of the 85 patients, 21 patients had patent veins, 47 patients had stenotic veins, and 16 patients had chronically occluded veins. In follow-up, symptomatic restenosis was seen in 3 patients and those veins were redilated. Two other patients had late occlusions at 23 and 63 months and received anticoagulation and redilatation, respectively. Using venography to guide postoperative management, 79 of 84 patients had patent veins many years postoperatively. Long-term patency, as seen by duplex scan, was achieved in nearly all patients using this protocol. [ABSTRACT FROM PUBLISHER]

A 54-year-old male presented to the vascular service for an urgent inpatient consultation. During an infusaport removal, the catheter was accidentally disconnected and lost intravascularly within the left subclavian vein, with the tip still in the right ventricle. We report on a novel technique for removing such intravascular foreign bodies (FBs), which will add a valuable technical option to our existing armamentarium regarding intracorporeal FB removal.
