Purpose: To evaluate the safety and feasibility of using drug-eluting balloons (DEBs) in the treatment of infrainguinal bypass graft stenoses.
Purpose: To report long-term outcomes of endovascular therapy (EVT) for aortoiliac bifurcation lesions.
Purpose: To compare the patency rates and clinical outcomes of balloon angioplasty vs. nitinol stent placement for patients with short (≤150 mm) as compared to long (>150 mm) femoropopliteal (FP) occlusive lesions.
Purpose To assess the extent of early recoil in patients with critical limb ischemia (CLI) undergoing conventional tibial balloon angioplasty.
Purpose: To evaluate the performance of the Turbo Elite laser catheter in combination with the Turbo-Booster guiding catheter for the treatment of femoropopliteal in-stent restenosis (ISR).
Purpose To report outcomes of a multicenter, nonrandomized study evaluating the safety and effectiveness of a guidewire-mounted mechanical recanalization device with a rotating distal tip (TruePath) in facilitating the crossing of infrainguinal chronic total occlusions (CTOs).
Purpose: To present a systematic safety evaluation of the CrossBoss blunt microdissection catheter for crossing peripheral chronic total occlusions (CTOs).
Purpose: To compare complication rates of a collagen-based vascular closure device (VCD) in patients with vs. without significant peripheral artery disease (PAD).
Purpose: To evaluate endovascular repair of type II and III thoracoabdominal aortic aneurysms (TAAA) using the Multilayer Flow Modulator (MFM) in patients with contraindications for open surgery and fenestrated stent-grafts.
Purpose: To scrutinize registry data on thoracoabdominal repairs performed using the Multilayer Flow Modulator (MFM) outside the indications for use (IFU) and analyze the adverse outcomes.
Endovascular aortic aneurysm repair (EVAR) is widely accepted as a less-invasive alternative to traditional open surgery in patients with an infrarenal abdominal aortic aneurysm. However, type II endoleaks continue to be the most common complications observed after EVAR, occurring in 19%–23% of patients (1,2). Type-II endoleaks are caused by retrograde collateral blood flow into the aneurysm sac from patent aortic side branches such as the inferior mesenteric artery (IMA), lumbar arteries, or median sacral artery (3). Type II endoleaks can be classified as simple or complex. Simple endoleaks have only one artery in communication with the aneurysm sac, whereas complex endoleaks have multiple communicating arteries (3). Persistent flow in the IMA is responsible for 45%–85% of all type II endoleaks after EVAR (4,5). Baum and colleagues (6) demonstrated that retrograde blood flow in the IMA transmits nearly systemic pressures to the aneurysm sac. Persistent pressurization of the aneurysm sac is significantly associated with aneurysm sac growth, repeated secondary intervention, conversion to open repair, and even aneurysm rupture (2,7,8).
Flow diverters provide a noninvasive way of treating aneurysms that are otherwise difficult to treat with other endovascular techniques. Even though flow diverters are widely applied, their exact mechanism of action remains unknown. Notwithstanding the term flow diverter, which implies that the primary mode of action is diversion of flow from the aneurysm (1–4), it remains unclear whether change in intraaneurysmal flow, tissue growth across the neck, or both processes are dominant predictors of long-term occlusion. Ongoing uncertainty regarding the exact healing mechanism associated with flow diverters has myriad consequences, including but not limited to impeding our ability to develop next-generation devices. The objective of our study was to characterize the progression of healing across aneurysm necks following treatment with a flow diverter in a rabbit model.
Background: Statins stabilize atherosclerotic plaque, decrease mortality after surgical procedures, and are linked to anti-inflammatory effects. The objective of this study was to evaluate preoperative administration of statins and longitudinal limb salvage after lower extremity endovascular revascularization and lower extremity open surgery.
