The IntellaMap Orion (Boston Scientific) is a 64-electrode basket catheter allowing for ultrahigh-density mapping of complex cardiac arrhythmias. We report the case of a basket catheter vascular entrapment, requiring surgical removal.

Background: The donor artery after a long-standing arteriovenous fistula (AVF) for hemodialysis usually evolves exceptionally toward a true aneurysmal degeneration (AD). The purpose of this article was to describe true brachial artery AD in end-stage renal disease patients after AVF creation, as well as its influencing factors and treatment strategies.

Methods: We present a retrospective, observational, single-center study realized in Caen University Hospital's Vascular Surgery Department from May 1996 to November 2015.

Intimal sarcoma is a rare and aggressive vascular pathology. The literature describes about 140 cases. Because of late diagnosis, the median survival time is only a few months.

Objective: This study evaluated, in a contemporary prospective series, the safety and efficacy of femoral endarterectomy using the eversion technique and compared our results with results obtained in the literature for the standard endarterectomy with patch closure.

Methods: Between 2010 and 2012, 121 patients (76% male; mean age, 68.7 years; diabetes, 28%; renal insufficiency, 20%) underwent 147 consecutive femoral bifurcation endarterectomies using the eversion technique, associating or not inflow or outflow concomitant revascularization.

Background: To evaluate the feasibility of early ambulation in patients treated for peripheral occlusive lesions by femoral percutaneous access, without the use of closure systems and the application to ambulatory practice.

Methods: This single-center observational exploratory study was undertaken among 99 consecutive patients between August 1-December 31, 2011 (mean age: 72 years; 72 men) who were treated by percutaneous femoral route for peripheral arterial lesions. All the patients had a manual compression then pressure bandage.

Type B aortic dissections complicated by pain, malperfusion, or aneurysm expansion mandate surgical intervention. Success of this therapy is predicated on exclusion and thrombosis of the false lumen of the aneurysm. This report presents a case in which cessation of flow was achieved using a covered stent graft to close a renal reentry tear after a previous closing and overstenting of the main tear.

We report the case of a 26-year-old woman who presented with embolic stroke from left common carotid artery compression by a gigantic clavicular osteochondroma. To our knowledge, this is the only such case described in the literature. The other particularity of this case is the delayed appearance of this childhood tumor.

Background: Long-term results of transluminal angioplasty (TLA) of the prevertebral subclavian artery (PVSA) are not well known. The aim of this work was to present a retrospective analysis of a consecutive series of 81 TLAs of the PVSA, with a mean follow-up of approximately 7 years (82 months).

Material And Methods: From January 1984 to May 2007, 81 TLAs of PVSA were consecutively performed in 72 patients (64% men; median age = 56.

Background And Aims: Angiotensin-converting enzyme insertion/deletion (rs4340) and angiotensin II type 1 receptor A1166C (rs5186) gene polymorphisms may be involved in coronary heart disease (CHD). This study was designed to evaluate potential relationships between these polymorphisms and the risk of long-term all-cause mortality and major adverse cardiovascular events (MACE) in patients requiring revascularization for atherothrombotic disease (ATD) lesions.

Method: This prospective observational study concerned patients referred for supra-aortic vessel disease (SVD), CHD, peripheral artery occlusive disease (PAOD) or visceral artery disease (VAD).

A case of persistent proatlantal artery (PA) is described in a 60-year-old woman who presented with cerebellar ataxia, homonymous hemianopia, and aphasia. Both Doppler scan and magnetic resonance angiography (MRA) showed agenesis of both vertebral arteries, 80% stenosis of the left internal carotid artery (ICA), and an anastomotic vessel between the left external carotid artery (ECA) and the left vertebral artery (LVA) with a tight stenosis at the origin. It was thought to be a type II PA.

Background: Ascending aortic aneurysms with normal sized sinotubular junction are generally treated by resection of the dilated aorta and replacement with tubular graft. Aortic resection and direct end-to-end anastomosis has been applied to repair aortic coarctation, interrupted aortic arch, and traumatic aortic rupture. No data exist regarding the long-term durability of this approach in ascending aortic aneurysms.
