Article Synopsis
  • The study explores the safety and effectiveness of using carbon dioxide (CO) as a contrast agent for endovascular abdominal aortic aneurysm repair (EVAR), comparing it to the traditional iodinated contrast medium (ICM).
  • Data was retrospectively analyzed from patients undergoing both CO and ICM guided EVAR procedures, finding a 100% technical success rate in both groups but observing higher radiation exposure in the CO group.
  • The results indicate that CO can be used safely for EVAR without relying on ICM, showing similarly low rates of kidney injury but necessitating caution due to increased radiation exposure.

Background: Despite promising early results, midterm failures of the Nellix endovascular aneurysm sealing (EVAS) system (Endologix Inc, Irvine, Calif) have been reported at higher than expected rates. The management of proximal endoleaks and migration differs from those after conventional endovascular aortic aneurysm repair (EVAR) owing to the peculiar design of the Nellix device. In the present study, we report a monocentric experience in the management of EVAS complications using various techniques.

Objective: Plaque stability is of utmost importance for stroke prevention in the perioperative period (within 24 hours) following carotid artery stenting (CAS). Although carotid plaque is entrapped between stent struts after stent deployment, postdilation can cause a scissoring effect on the plaque, increasing the risk of postprocedural embolic events due to plaque prolapse. Maximum carotid plaque dilation before stent deployment may reduce this risk.

Objective: The objective of this study was to evaluate the results of the off-label use of the Nellix endograft (Endologix, Irvine, Calif) for the treatment of short-neck aneurysms and juxtarenal aortic aneurysms (JAAs) compared with the outcomes of patients with infrarenal abdominal aortic aneurysms treated in accordance with the manufacturer's instructions for use.

Methods: Data available from patients treated with the Nellix endograft from September 2013 to January 2016 were reviewed to create a case-control analysis (1:2). Fourteen elective patients with a short-neck aneurysm or JAA (<10 mm) and mild aortic neck angulation (<35 degrees) were included.

Purpose: To report midterm outcomes of the Nellix Endovascular Aneurysm Sealing (EVAS) System in the treatment of abdominal aortic aneurysm (AAA).

Methods: Between September 2013 and July 2014, 64 AAA patients (mean age 76.6±6.
