Nitinol overdose-rescue of acute limb ischemia caused by stenting of the common iliac, external iliac, common femoral, superficial femoral, and popliteal arteries in an actively smoking patient with claudication.

Intermittent claudication (IC) from peripheral arterial disease is typically managed with pharmacologic interventions and lifestyle changes. However, despite societal guidelines, initial endovascular interventions are being used more frequently with an increased incidence of complications, resulting in rapid disease progression to critical and acute limb-threatening ischemia (ALI). The present report describes the case of a patient who developed ALI after treatment of IC at another facility, with malpositioned bilateral common iliac stents, continuous stent extension into the popliteal artery, and acute occlusion of the entirety of the right lower extremity vasculature.

Endovascular Revascularization Incorporating Infrapopliteal Coronary Drug-Eluting Stents Improves Clinical Outcomes in Patients with Critical Limb Ischemia and Tissue Loss.

Background: Critical limb ischemia (CLI) involving infrapopliteal arterial atherosclerosis and tissue loss remains a formidable clinical scenario with significant morbidity and mortality. Despite level IA evidence, tibial revascularization with coronary drug-eluting stents (DES) remains a seldom-used technique in the United States due, in part, to lack of a Food and Drug Administration-approved indication and dedicated stent technology for infrapopliteal application. Furthermore, follow-up data beyond 1 year remain scarce, and further evidence for improvement in clinical outcomes using this technique is needed.

Covered Stent Treatment of a Chronically Thrombosed Popliteal Artery Aneurysm in the Setting of Critical Limb Ischemia following Multiple Failed Bypass Operations.

Endovascular salvage of failed surgical bypasses has been scantly reported for treatment of infrainguinal occlusive disease. Although catheter-directed thrombolysis and/or mechanical thromboembolectomy have been the mainstay of endovascular salvage of previous bypass grafts, native vessel recanalization remains seldom attempted. Herein, we present a unique approach to native vessel recanalization of a chronically thrombosed popliteal artery aneurysm for nonhealing distal ulceration.

An institution-wide algorithm for direct-stick embolization of peripheral venous malformations.

Objective: No standardized therapeutic algorithm or embolic agent of choice has yet been identified for management of congenital peripheral venous malformations (VMs). Treatment options and reported outcomes therefore vary widely. Herein, we present an institution-wide algorithm for management of symptomatic congenital peripheral VMs using a single embolotherapeutic modality.

Transcatheter embolization of persistent embryonic veins in venous malformation syndromes.

Persistent embryonic veins represent a major source of venous hypertension and morbidity in venous malformation syndromes, such as Klippel-Trénaunay syndrome and congenital lipomatous overgrowth, vascular malformations, epidermal nevus, and skeletal deformities syndrome. Surgical stripping and phlebectomy are the most commonly reported alternatives to compression therapy for refractory cases. These techniques, although effective in those patients who meet the necessary anatomic criteria, can be associated with bleeding, wound-related complications, and recurrence.

Endovascular Reconstruction for Chronic Infrarenal Aortoiliac Occlusive Disease.

According to the 2007 TransAtlantic Inter-Society Consensus (TASC II) guidelines, surgery is the preferred treatment for extensive (TASC II type C and D) aortoiliac occlusive disease (AIOD). Recent studies, however, have shown that endovascular management can be an effective first-line treatment option for TASC II type C and D categories. While endovascular therapy is now commonly performed in patients with TASC II type D lesions, very few studies have investigated the feasibility and effectiveness of extending endovascular therapy to the most severe subcategory of TASC II D lesions, chronic infrarenal aortoiliac occlusion (CIAO).

Transcervical Carotid Stent Placement in the Setting of a Hostile Neck and a Type III Aortic Arch.

Previous radical neck dissection and neck irradiation pose considerable operative risks in patients requiring carotid endarterectomy for symptomatic carotid disease. Carotid stenting is an acceptable alternative for these patients but carries a higher risk of cerebrovascular accidents especially in patients with type III aortic arch anatomy. Herein, we present a technically challenging case of a patient with an irradiated neck and a history of radical neck dissection who presented with a symptomatic high-grade left internal carotid artery stenosis in the setting of a type III aortic arch.

Palliative Endovascular Techniques for Management of Peripheral Vascular Blowout Syndrome in End-Stage Malignancies.

Vascular blowout syndrome (VBOS) secondary to neoplastic erosion is a dreadful complication of advanced stage malignancies that can compromise quality of life and overall prognosis in a fragile patient population. Endovascular therapy can offer minimally invasive, life-saving maneuvers both acutely and prophylactically. Four patients with end-stage malignancies eroding into various peripheral vascular beds with impending, threatened, and acute VBOS underwent successful endovascular management.

Stent-Assisted Coil Embolization of a Symptomatic Renal Artery Aneurysm at a Bifurcation Point.

Background: Symptomatic renal artery aneurysms at bifurcation points present challenging clinical scenarios rarely amenable to endovascular repair due to concerns regarding parenchymal loss following intervention. Herein, we add to the scant body of literature describing successful endovascular repair of a saccular, symptomatic renal artery aneurysm situated at a bifurcation point.

Methods: A 52-year-old woman with a 2.

Outcomes after Distal Pancreatectomy for Trauma in the Modern Era.

Multiple stump closure techniques after distal pancreatectomy (DP) for trauma have been described, and all are associated with a significant fistula rate. With increasing emphasis on abbreviated laparotomy, stapled pancreatectomy has become more common. This study describes the outcomes of patients with different closure techniques of the pancreatic stump after resection following pancreatic trauma.
