Stent News and Research

A stent is a small mesh tube that’s used to treat narrowed or weakened arteries in the body.

You may have a stent placed in an artery as part of a procedure called angioplasty (AN-jee-oh-plas-tee). Angioplasty can restore blood flow through narrowed or blocked arteries. Stents help prevent arteries from becoming narrowed or blocked again in the months or years after treatment with angioplasty. You may also have a stent placed in a weakened artery to improve blood flow and to help prevent the artery from bursting.

Stents are usually made of metal mesh, but sometimes they’re made of fabric. Fabric stents, also called stent grafts, are used in larger arteries. Some stents are coated with medicines that are slowly and continuously released into the artery. These medicines help prevent the artery from becoming blocked again.

Loyola surgeon performs minimally invasive emergency procedure to repair AAA

Jack Kory of Mokena, Il. was eating his breakfast oatmeal when he suddenly felt the worst pain in his life. The searing pain came on suddenly in his stomach and spread to his knees. It was caused by an abdominal aortic aneurysm (AAA) that had suddenly burst, causing massive internal bleeding. Traditionally, few patients have survived such ruptures. But Loyola University Medical Center vascular surgeon Dr. Richard Hershberger was able to repair Kory's aneurysm with a minimally invasive emergency procedure.
