Background: Patients with femoral vein occlusion rapidly develop collateral flow through the deep femoral vein, an embryonic collateral. In contrast, iliac vein collateralization is sparser and functionally poorer. It is not uncommon to have femoral vein occlusions associated with iliac vein obstruction, even though the femoral vein occlusion is often more readily apparent on venograms and duplex scans, whereas the iliac vein obstruction may remain occult. We examined whether percutaneous stent correction of iliac vein obstruction associated with femoral vein occlusions would yield symptomatic relief.
Objective: The purpose of this study was to review preoperative and postoperative duplex scans and postoperative venograms in patients with subclavian vein thrombosis who underwent first rib resection and scalenectomy (FRRS) during 2005 to 2013.
Objective: The aim of this study was to assess the management and outcomes of arteriovenous malformations (AVMs) with a dominant outflow vein (DOV) treated with retrograde venous embolization.
Objective: Superficial venous reflux disease has been treated with endovenous ablation techniques for more than 15 years. Thrombi discovered in the postoperative period are referred to as endovenous heat-induced thrombi (EHIT). In spite of the few studies of the ultrasound differentiation between EHIT and deep vein thrombi (DVT), there remains a paucity of literature regarding the evaluation of ultrasound examination and pathologic differentiation.
Objective: Activation of proteolytic mechanisms at the cell surface through the activity of urokinase-type plasminogen activator (uPA) bound to its receptor, uPAR, is an important process in wound healing. The soluble forms of uPAR (suPAR and its fragments I, II, and III) have nonproteolytic functions that include chemotaxis, adhesion, and proliferation, which also have a role in wound healing. The aim of this study was to determine whether suPAR and its cleaved fragments are present in venous ulcers and whether their levels are associated with healing.
Objective: We conducted a systematic review of the literature about quality-of-life (QOL) scales in chronic venous disorders (CVDs) comprising leg ulcers to identify the respective advantages and deficits of existing tools.
Background: Inferior vena cava (IVC) filter placement is performed to mitigate the risk of pulmonary embolism (PE) when anticoagulation is contraindicated or ineffective. Technical advances now allow catheter-based filter retrieval. Many believe the benefits of retrieval are self-evident, yet retrieval carries an inherent complication risk and cost. The purpose of this study was to quantitatively weigh the risks and benefits of IVC filter retrieval using formal decision analysis.
Objective: Greater flexibility and smaller sizes for introducer sheaths in the newest stent grafts increase the feasibility of endovascular aneurysm repair but raise concerns about long-term limb patency. The aim of the study was to determine the incidence of and predictive factors for limb occlusion after use of the Endurant stent graft (Medtronic Inc, Minneapolis, Minn) for abdominal aortic aneurysm.
Objective: The objective of this study was to report long-term results of early endovascular aortic aneurysm repair after percutaneous coronary intervention (PCI).
Objective: Management of type II endoleaks after endovascular aneurysm repair can be problematic. This study reports our experience with a relatively novel strategy to treat this complication, transcaval coil embolization (TCCE) of the aneurysm sac.
Objective: This study determined the incidence, the surgical details, and the outcome of late open conversion after failed endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm.
Objective: The effect of stent graft fixation type on renal function after endovascular aneurysm repair (EVAR) remains controversial. This systematic review and meta-analysis was conducted to determine whether suprarenal (SR) or infrarenal (IR) fixation influences the risk of renal complications after EVAR.
Objective: Kissing stents (KS) are commonly used to treat aortoiliac occlusive disease, but patency results are often lower than those of isolated stents. The Covered Endovascular Reconstruction of the Aortic Bifurcation (CERAB) technique was recently introduced to reconstruct the aortic bifurcation in a more anatomical and physiological fashion. The aim of this study is to compare the geometrical consequences of various stent configurations in vitro.
Objective: The purpose of this study was to assess the efficiency of bare-metal stenting of the thoracoabdominal aorta in a human ex vivo model of acute type B aortic dissection and the impact of this approach on the patency of the visceral and renal arteries.
Objective: Despite wide use, high initial success, and acceptable durability of endovascular therapy (EVT) for femoropopliteal (FP) lesions, the frequency of 30-day perioperative complications (POCs) and their effect on clinical outcomes have not been systematically evaluated, which is the subject of this study.
