Iliofemoral Vein Stenting in a Patient with Pelvic Metastasis.

We report a case of an 81-year-old woman with extensive pelvic lymphadenopathy that caused severe stenosis and occlusion of the right common and external iliac veins and proximal common femoral vein. Pelvic lymphadenopathy resulted from the recurrence of a previous right ovarian epithelial tumor. The patient had severe right lower extremity edema, consistent with severe venous insufficiency. She was treated with high-pressure balloon angioplasty (12-14 mm in diameter) and four self-expanding stents (14-10 mm diameter, 80-40 mm length). The postoperative response was dramatic to a near-complete resolution of the edema. The venous clinical severity scores were 10 and 2 at presentation and 6 months after the follow-up, respectively. Balloon angioplasty and stenting are safe and effective methods for providing symptomatic relief for lower extremity venous insufficiency in patients with extensive and unresectable pelvic masses.

Management of traumatic subclavian artery injuries in a high-volume vascular surgery center in Iran.

Introduction: Subclavian artery injury is an uncommon vascular trauma with potential morbidity and mortality. Management of subclavian artery trauma requires open and endovascular techniques and timely and efficacious decision is mandatory. We retrospectively reviewed traumatic subclavian artery injuries in a high-volume vascular surgery center in Iran. Methods: In a retrospective study, we assessed subclavian artery injuries during 6 years in ShohadaTajrish Medical Center. Background characteristics, type of incision, type of operation and outcome of patients were evaluated. Results: A total of 14 patients had subclavian artery injury (mean age 29.9 ± 13.4 years, 92.9% male). Trauma was in left and right sides in eight (57.1%) and six patients (42.9%) respectively. Arteriorrhaphy, interposition and ligation of injured artery was done in 7 (50.0%), 3 (21.4%) and 4 (28.6%) patients respectively. Associated nerve injury was present in six patients (42.9%). Endovascular proximal control was obtained in six patients (42.9%) prior to vascular exposure. Time of patient referral did not have significant association with shock or type of operation (P > 0.05). Conclusion: Although traumatic subclavian artery injuries are rare, its vascular exposures and reconstructions are of potential clinical concern. Endovascular interventions can facilitate proximal control. In addition, endovascular repair by covered stent is an alternative to open surgery.

Iliac vein aneurysms: a comprehensive review.

Introduction: Iliac vein aneurysm is a rare clinical entity. Iliac venous tract is the least commonlocation for venous aneurysms. There are a few cases of common, external and internal iliac veinaneurysms in the literature. However, undiagnosed and ruptured iliac venous aneurysms couldhave hazardous consequences. Herein, we reviewed all literature cases of iliac vein aneurysms.Their potential diagnostic and therapeutic challenges are discussed. Literature Review: Following a systematic search, 50 cases of iliac venous aneurysms wereidentified. We used MEDLINE [1900-March 2018] and EMBASE [until March 2018]. MeSHterms of iliac vein/veins/venous, hypogastric, inferior vena cava and aneurysm/aneurysms wereused. Fifty patients with venous aneurysms located in common, external or internal iliac veinswere found in our systematic search. Seventeen patients were female (35.4%) and 31 patients weremale (64.6%). The age range was 13 to 70 years of age. The aneurysm was located in right side in17 patients (34%). It was located in left side in 29 patients (58%) and it was bilateral in 4 patients(8%). The aneurysm was located in common, external and internal iliac veins in 15 (30%), 31(62%) and 4 (8%) patients respectively. The aneurysm was due to a previous arteriovenousfistula (AVF) in 19 patients (38%) and of them, 16 patients (32%) had a history of AVF resultingfrom a previous trauma. 29 patients (59.2%) underwent open surgical treatment. Five patients(10.2%) underwent endovascular treatment. One patient (2.0%) underwent hybrid treatment.Conservative treatment was used in 14 patients (28.6%). Conclusion: Iliac vein aneurysms are extremely rare. Its diagnosis necessitates precise clinicalsuspicion and the treatment is based on patients' clinical scenario and radiological features. Bothopen and endovascular techniques could be feasible. Iliac vein aneurysms are more commonin men. Left sided aneurysms are more common. The most common anatomic location isexternal iliac vein. The most common cause of iliac aneurysms is dilatation of vein secondary toa traumatic AVF.
