BACKGROUND: The endovascular aneurysm repair (EVAR) is becoming the preferred method to treat an aortic aneurysm with its better short-term postoperative mortality and morbidity rates in comparison with the open repair. A main drawback of this method is the need to use a nephrotoxic iodinated contrast medium to visualize the aorta and its side branches. CASE REPORT: An 83-year-old man with an asymptomatic infrarenal aortic aneurysm of a 51-mm diameter accompanied by a 42-mm aneurysm of the left common iliac artery was treated with combined fenestrated EVAR (FEVAR) and iliac side branch stent graft (ISBG) under guidance of image fusion (IF) without the intraoperative use of iodinated contrast agent...

BACKGROUND: Carotid stent and/or angioplasty (CAS) via the transfemoral route with distal protection carries twice the risk of stroke and/or death when compared with carotid endarterectomy (CEA) in multiple randomized trials. Potential causes for this include disadvantaged aortic arch anatomy and the need to traverse the lesion to place a distal protection device. This report describes the technique and our experience with direct CAS using flow reversal for embolic protection. METHODS: University of California at Los Angeles (UCLA) division of Vascular and Endovascular surgery was a participant in the multi-institutional Roadster Trial of high-risk patients...

Antiphospholipid antibody syndrome (APS) is usually a disease of young adults. In elderly stroke patients APS was not associated with progressive intracerebral stenosis in the past. Here, we report a 65-year-old patient who presented with recurrent ischemic strokes associated with progressive stenosis of the right middle cerebral artery. Antiphospholipid antibodies were detected and treatment with plasma exchange, tapered steroids, and anticoagulants was successful. This case demonstrates that APS should be considered also in elderly stroke patients...

Esophagectomy with extended lymphadenectomy and gastric conduit reconstruction is a radical procedure for the treatment of esophageal cancer that is associated with a high morbidity rate. Gastric conduit necrosis is a fatal complication that occurs in 2% of patients. Conventionally, two-stage salvage surgery consisting of removal of the necrotic gastric conduit followed by reconstruction has been performed; however, this procedure has a high morbidity rate. We describe a 61-year-old man who underwent minimally invasive esophagectomy complicated by slowly progressive gastric conduit necrosis associated with complete neck drainage and a stable overall condition...

Flow-diverting stents, including the Pipeline embolization device (PED) and Silk, have been beneficial in the treatment of aneurysms previously unable to be approached via endovascular techniques. Recurrent aneurysms for which stent-assisted embolization has failed are a therapeutic challenge, given the existing intraluminal construct with continued blood flow into the aneurysm. We report our experience using flow-diverting stents in the repair of 25 aneurysms for which stent-assisted embolization had failed...

We describe a case of iatrogenic carotid injury with secondary carotid-cavernous fistula (CCF) treated with a silk flow diverter stent placed within the injured internal carotid artery and coils placed within the cavernous sinus. Flow diverters may offer a simple and potentially safe vessel-sparing option in this rare complication of transsphenoidal surgery. The management options are discussed and the relevant literature is reviewed.
