Endovascular surgery for arterial occlusive disease and aneurysms is a minimally invasive technique used to treat problems in the blood vessels. This approach is preferred because it involves smaller incisions and generally leads to quicker recovery times compared to traditional open surgery.

For arterial occlusive disease, where arteries are narrowed or blocked, the procedure often starts with a small incision, usually in the groin or arm. A thin tube called a catheter is inserted and guided through the blood vessels to the affected area. Doctors may use techniques like balloon angioplasty, where a small balloon is inflated to open the artery, or they may place a stent—a small mesh tube—to keep the artery open.

In the case of aneurysms, which are bulges in a blood vessel that can be dangerous if they rupture, endovascular surgery involves placing a stent-graft. This is a combination of a stent and a graft that is inserted through a catheter. Once in place, it reinforces the artery wall and helps prevent the aneurysm from growing or bursting.

The procedures typically take about one to three hours and are performed under local anesthesia or sedation. Patients often experience less pain and a shorter hospital stay, with many being able to return home the same day or within a day.

Overall, endovascular surgery is effective and has a lower risk of complications compared to traditional methods.
