Vascular Disease/Aortic Aneurysm/Peripheral and Carotid Artery Disease
- Vascular Stenting
- Aortic Stent Grafting
Angioplasty—with or without vascular stenting—is a minimally invasive procedure performed to improve blood flow in the body’s arteries and veins.
In an angioplasty procedure, imaging techniques are used to guide a balloon-tipped catheter (a long, thin plastic tube) into an artery or vein and advance it to where the vessel is narrow or blocked. The balloon is then inflated to open the vessel, deflated and removed.
During angioplasty, a small wire mesh tube called a stent may be permanently placed in the newly opened artery or vein to help it remain open. There are two types of stents: bare stents (wire mesh) and covered stents (also commonly called stent grafts).
Aortic Stent Grafting
An increasing number of patients are benefiting from the endovascular repair of abdominal aortic aneurysm. Improvements in device design now enable less invasive aortic stent grafting in patients who were previously candidates for open aneurysm repair. Recent clinical studies show endovascular aneurysm repair patients have lower perioperative mortality, less operative blood loss and lower transfusion requirements compared with patients undergoing open surgery. Because patients can return home the following day, length of hospital stay is dramatically reduced.
