Endovascular Abdominal Aneurysm Repair and Impact of Systematic Preoperative Embolization of Collateral Arteries: Endoleak Analysis and Long-term Follow-up

Abstract

Preoperative collateral embolization seems to be a valid method of reducing the incidence of type II endoleak, improving the long-term outcome.

Characteristics and Risk Factors for Type 2 Endoleak in an East Asian Population From a Japanese Multicenter Database

“…12 Because the key to T2EL ceasing is thrombus formation within residual aneurysm sac, many reports have focused on the parameters that affect thrombus formation: from antiplatelet therapy and anticoagulation 27-30 to metabolic syndrome, 31 smoking, 6,10 anatomy of the aortic branches, 17,32 and preoperative embolization of the aortic branches. 33, 34 The current literature, however, lacks information about ethnic differences in T2EL.…”

Identification of Predictive CT Angiographic Factors in the Development of High-Risk Type 2 Endoleaks after Endovascular Aneurysm Repair in Patients with Infrarenal Aortic Aneurysms

“…What do these results mean for the endovascular treatment of patients with an AAA? Systematic preoperative embolization of all aortic side branches in the region of the aneurysm reduces the number and size of type 2 endoleaks after EVAR [33,34]. On the other hand this means another intervention that is technically demanding, time-consuming, and has a certain risk of complications [35].…”

Long-term Outcomes of a Telementoring Program for Distant Teaching of Endovascular Aneurysm Repair

“…Indications for EVAR were (1) saccular or fusiform aneurysms with a ≥50-mm diameter or rapid progression (>5 mm/y); (2) a proximal neck ≥10 mm long, ≤30 mm in diameter, and with <60° angulation; (3) at least one 6.5-mm-diameter external iliac artery; and (4) a maximum 20-mm-diameter distal landing zone. 7 After the telementoring period, 86 patients (mean age 71 years; 77 men) underwent EVAR procedures carried out at the secondary care center from November 2003 to July 2011 and were monitored in an ongoing assessment protocol. The AAA eligibility criteria for EVAR were the same as during the telementoring period.…”
