Endovascular techniques with coil embolization have been used in certain visceral aneurysm cases, often resulting in sacrifice of the involved visceral vessel and end-organ thrombosis. We describe two cases in which stent grafts were used to treat these aneurysms, allowing preservation of visceral artery and end-organ flow while completely excluding the(More)
BACKGROUND Adipose tissue is a readily available source of multipotent adult stem cells for use in tissue engineering/regenerative medicine. Various growth factors have been used to stimulate acquisition of endothelial characteristics by adipose-derived stem cells (ASC). Herein we study the effects of endothelial cell growth supplement (ECGS) and(More)
May-Thurner syndrome is a rare clinical entity involving venous obstruction of the left lower extremity. Obstruction occurs secondary to compression of the left common iliac vein between the right common iliac artery and the underlying vertebral body. Current management largely involves endovascular therapy. A review was conducted of six studies containing(More)
Infrainguinal occlusive disease is a complex problem necessitating the cooperation of both medical and surgical therapies to aid limb salvage and alleviate symptoms. Endovascular therapies are varied, with no treatment clearly outweighing the other in terms of efficacy and durability. Angioplasty for focal stenosis has gained ground as the treatment of(More)
OBJECTIVE Successful endovascular aortic aneurysm repair depends on exclusion and spontaneous thrombosis of the aneurysm sac. The need for chronic postoperative anticoagulation therapy could limit the applicability of this technology with delay or prevention of sac thrombosis resulting in endoleak formation and altered remodeling of the aneurysm sac. The(More)
The treatment of external carotid artery stenosis has been described with a variety of operative interventions. We present a patient who presented with amaurosis fugax and a critical left external carotid artery stenosis with known left internal carotid artery occlusion. We treated this stenosis with angioplasty and stenting rather than endarterectomy. Our(More)
