Post-market European & Asian Registry to Evaluate the Minos™ Stent-Graft and Delivery System in Abdominal Aortic Aneurysm Treatment (PEARL)

A Prospective Multi-centre Observational Real-world Post-market European & Asian Registry With Low-profile Minos™ Abdominal Aortic Stent Graft

The Minos™ Abdominal Aortic Stent-Graft and Delivery System is a medical device designed to treat abdominal aortic aneurysms using a minimally invasive procedure. The device is placed inside the aorta through blood vessels, usually accessed through small incisions in the groin. The goal of this observational study is to collect short-, medium- to long-term safety and performance data of the Minos™ stent-graft in everyday medical practice (real-world settings). The aim is to study about 200 patients worldwide and at least 30 patients in European hospitals.

Incidence of type I and type III endoleaks from 30 days to 5 years post-procedure
Délai: From 30 days post-implantation until end of follow up at 5 years
