OBJECTIVE: Hybrid operative thrombectomy (HOT) is a novel technique for the treatment of acute iliofemoral deep venous thrombosis (IFDVT) and is an alternative to percutaneous techniques (PTs) that use thrombolytics. In this study, we compare perioperative and intermediate outcomes of HOT vs PT as interventions for early thrombus removal. METHODS: From July 2008 to May 2015, there were 71 consecutive patients who were treated with either PT (n = 31) or HOT (n = 40) for acute or subacute single-limb IFDVT...

OBJECTIVE: During endovascular aneurysm repair (EVAR), severely tortuous aortoiliac anatomy can alter the deployment and conformability of the endograft. The accuracy of treatment length measurements is commonly recognized to be affected by severe tortuosity. However, the exact mechanism of the postintervention length discrepancy is poorly understood. The objective of this study was to determine the mechanism of how severe aortoiliac tortuosity influences the endograft and native aorta during EVAR and its impact on the distal sealing zone...

BACKGROUND: The structural limitations of currently available laser-cut nitinol stents in the highly diseased arterial system of the lower extremity are well described. These devices are frequently used in long-segment occlusions, at the adductor hiatus, and across the knee into the popliteal artery and tibial-peroneal trunk despite concerns related to the high mobility of the knee joint and the potential for external stent compression, fractures, and occlusion. The Supera stent (Abbott Vascular, Santa Clara, Calif) was developed to provide superior radial strength, fracture resistance, and flexibility compared with laser-cut nitinol stents...

BACKGROUND: Percutaneous femoral vascular access is frequently used for aortic endovascular procedures, with a local access complication rate of 5% to 16%. Fenestrated endovascular aneurysm repair (FEVAR) has recently emerged as a new technique for the repair of short-neck and juxtarenal abdominal aortic aneurysms. The safety and effectiveness of percutaneous access for FEVAR has not been established to date. METHODS: Since United States Food and Drug Administration approval of the Zenith fenestrated aortic endograft (Cook Medical, Bloomington, Ind), 94 patients (60 Zenith fenestrated, 6 p-Branch, and 28 custom-made devices) have undergone FEVAR...

OBJECTIVE: This study evaluated changes in aortic neck diameter after endovascular aneurysm repair (EVAR) using a balloon-expandable stent (BES) endograft compared with a commercially available self-expanding stent (SES) endograft. We hypothesized that forces applied to the aortic neck by SES endografts may induce aortic neck enlargement over time and that such enlargement may not occur in aneurysm patients treated with a device that does not use a proximal SES. METHODS: This was a retrospective quantitative computed tomography (CT) image analysis of patients treated with the Nellix (Endologix, Irvine, Calif) BES (n = 49) or the Endurant II (Medtronic, Minneapolis, Minn) SES (n = 56) endograft from 2008 to 2010...
