“…Little is known about endobag rupture during EVAS and the potential effects of polymer to the body. One comparable case is previously published, 14 showing a patient who underwent an EVAS procedure for an anastomotic aneurysm resulting in rupture and displacement of polymer material causing peripheral ischemia and renal and visceral occlusion. After removal of the filling material by open surgery, the patient completely recovered.…”

“…5 Furthermore, the need for secondary interventions after EVAR poses a further challenge. [4][5][6] The most common indication for any reintervention after EVAR is the persistent perfusion of the aneurysm sac, which is called an endoleak (EL). 7,8 If EL can be detected after EVAR, the risk of a fatal rupture increases.…”

Background Endovascular aortic aneurysm repair (EVAR) has become the standard procedure for treating infrarenal abdominal aortic aneurysms (AAA). Various associated complications can lead to open conversion (OC). Thorough follow-up after the procedure is mandatory for the early detection of complications. Persisting perfusion of the aneurysm, a so-called endoleak (EL), paired with structural instability because of aortic wall atrophy and impaired cell functionality induced by EVAR, results in a high risk for aortic rupture. Purpose The goal of this study was to detect the risk factors for elective and urgent OC as a result of EVAR-induced pathophysiological changes inside the aortic wall. Research Design Retrospective data analysis was performed on all open aortic repairs from January 2016 to December 2020. Data Collection and Analysis Fifty patients were identified as treated by OC for failure of an infrarenal EVAR. The patients were divided into two subgroups, here depending on the urgency of surgery. Statistical analysis of patient characteristics and outcomes was performed. Results The most common indications for OC were various types of EL (74%), resulting in an aortic rupture in 15 patients. Patients with insufficient or absent follow-up were treated more frequently in an emergency setting (16% vs. 63%). The mortality rate was higher in cases of emergency OC (3% vs. 26%). Conclusions Particularly in cases of insufficient or absent follow-up, complications such as EL pose an enormous risk for fatal aortic rupture.

Endovascular treatment of a type IA endoleak was conducted using a Nellix chimney graft technique for an expanding abdominal aortic aneurysm in an 84-year-old man. During the procedure, a polymer leak occurred from one of the endobags. Postoperatively, the patient developed hemodynamic instability and a swollen leg on the side of the leaking endobag, resulting in a fatal outcome. (J Vasc Surg 2019;69:1936-9.)
