Preoperative Sizing to Lower In-Stent Restenosis in Peripheral Arterial Occlusive Disease.

Background: The primary treatment for lower-extremity peripheral arterial occlusive disease (PAOD) is angioplasty stenting. Its main complication is in-stent restenosis. Poor selection of stent dimensions has been identified as a factor contributing to early in-stent restenosis.

Ultrasound-guided Angioplasty of Arteriovenous Fistulas for Hemodialysis: Benefits and Limitations.

Background: Ultrasound-guided percutaneous angioplasty of arteriovenous fistulas (AVFs) makes it possible to avoid contrast agents and X-rays, to optimize the puncture site and to locate some stenoses on the fistulography, but is it really useful? Our objective is to report the results of our experience.

Methods: Between November 2012 and November 2017, all the patients treated according to this method in our center were collected retrospectively. The surgical indications were an insufficient maturation of the AVF, an increase in the venous pressure, an inadequate outflow, difficulties in puncture, a prolonged bleeding time, a flow drop, or an aneurysmal evolution.

Influence of the contralateral carotid artery on carotid surgery outcome.

Background: Any obstacle in the contralateral artery has long been considered a high risk for carotid surgery. Here, we report the results of a monocentric, continuous, consecutive, prospective series and present a review of the literature.

Methods: All carotid endarterectomies performed under locoregional anesthesia in our department between 2003 and 2010 were recorded in a prospective database (n = 1,212).

Celiacomesenteric trunk: a variation that must be known before aortic surgery.

The celiac trunk and the mesenteric arteries may present variations with different clinical significance. A celiacomesenteric trunk was discovered in a patient with mesenteric ischemia and a history of aortic bypass without inferior mesenteric artery reimplantation. Despite thrombectomies and digestive resections, the patient died.
