Endovascular Aneurysm Repair Devices: Advancing Minimally Invasive Vascular Care
Endovascular Aneurysm Repair (EVAR) devices have revolutionized the treatment of abdominal aortic aneurysms (AAA) and other vascular abnormalities. Traditionally, open surgical repair was the primary approach, involving large incisions and extended recovery periods. EVAR offers a minimally invasive alternative, significantly reducing surgical trauma, hospital stay, and overall patient risk.
These devices primarily consist of stent grafts—flexible, fabric-covered metallic frameworks designed to reinforce weakened sections of blood vessels. During the procedure, a catheter is inserted through small incisions in the femoral arteries and guided to the site of the aneurysm. Once in place, the stent graft expands to form a new lumen, effectively redirecting blood flow and preventing aneurysm rupture.
One of the key advantages of EVAR devices is their adaptability. Modern stent grafts come in various sizes and configurations, including modular and fenestrated designs. Modular devices allow surgeons to customize the…
