Endovascular Intervention at Memorial Cardiac and Vascular Institute

Angioplasty and Stenting

Endovascular intervention involves angioplasty and stenting of blood vessels throughout the body, since arteriosclerosis tends to be a widespread condition affecting peripheral as well as coronary arteries. These procedures are performed by interventional radiologists, interventional neuroradiologists, interventional cardiologists and specially trained vascular surgeons, usually working together as a team.

Memorial Cardiac and Vascular Institute has a very active program of carotid artery stenting for the prevention of stroke that utilizes a newly approved intravascular filtering device in conjunction with angioplasty and stenting. We also are a regional training center for teaching this procedure. Our Brain Attack Program is a Joint Commission-certified stroke program and is available 24 hours a day, 7 days a week.

A major component of acute stroke treatment by our Brain Attack Team is neurovascular intervention by highly skilled specialists. Intravascular administration of clot-dissolving drugs in the earliest minutes and hours of a stroke can be critical in preventing serious brain injury and neurological impairment, similar to intervention during a heart attack.

Angioplasty and stenting of the arteries that supply blood to the legs helps treat a circulatory condition called "intermittent claudication", due to peripheral vascular disease (PVD), which causes dull, cramping pain in the hips, thighs or calf muscles while walking, and occasionally while at rest. Rotoblator techniques that shave large quantities of plaque are often used as part of these procedures. Deep vein thrombosis of the legs is sometimes treated by interventional procedures. Vascular intervention also may be used in the arteries that supply blood to the kidneys to treat some forms of kidney disease and to treat uncontrolled high blood pressure.

We have a very active aortic stent graft program for nonsurgical treatment of abdominal aortic aneurysms (weakened areas of the wall of the aorta). Stent grafts are devices that are inserted into the abdominal aorta by endovascular interventional techniques performed by a team of experts.

Embolization therapy is a type of procedure used by our interventional radiologists to treat a variety of conditions. Various substances can be passed through a catheter to seal bleeding arteries or starve tissue of its blood supply and create an effect similar to surgical removal. Chemotherapy drugs can be delivered through this method, as well.

This therapeutic approach has been used to:

  • Resolve hemorrhage in the upper or lower gastrointestinal tract
  • Control traumatic arterial hemorrhage
  • Treat benign and malignant tumors
  • Treat uterine fibroids to avoid hysterectomy
  • Reduce vascular malformations

Memorial Cardiac and Vascular Institute is one of only a few centers that offer advanced, neurointerventional procedures to treat complex cerebrovascular conditions, such as cerebral aneurysms and vascular malformations. In addition, our vascular surgeons have a long track record of excellence in performing such surgical procedures as carotid endarterectomy, abdominal aortic aneurysm repair and peripheral artery bypass.
