Using Interventional Radiology to Treat Stroke

We provide immediate evaluation and treatment of all stroke emergencies 24 hours a day, seven days a week, in our Biplane Interventional Radiology Suite. Advanced endovascular stroke treatment is less invasive than traditional surgery and provides an expanded time window for treating patients. Certain endovascular treatments can greatly benefit patients if performed within 24 hours after symptoms begin.

For more information on Interventional Radiology procedures, please call 941-745-7217.

Advanced Stroke Treatments

Treatments we provide include:

Mechanical Thrombectomy for Acute Stroke

For large blood clots, a thrombectomy is performed using a device called a stent retriever to remove the clot. A catheter is inserted into an artery in the groin and guided to the blocked artery in the brain. The stent retriever then opens and grabs the clot, allowing doctors to remove it.

Carotid Angioplasty/Stenting

Angioplasty is a procedure to open narrowed or blocked blood vessels to restore blood flow. A tiny balloon is temporarily inserted in the clogged artery and inflated to widen the area. This is often combined with stenting to help decrease the chance of the artery clogging again.

Cerebral Angiography

This test provides images of blood vessels in and around the brain. It enables physicians to detect abnormalities such as arteriovenous malformations (AVMs) and aneurysms.

Carotid Artery Endarterectomy

If you have carotid artery disease, an endarterectomy can help prevent a stroke from occurring. When plaque builds up in the carotid artery, it can reduce blood flow to the brain. During this procedure, the artery is opened or cleaned to improve blood flow.

Spinal Arteriovenous Malformation Treatment

AVM is a rare and abnormal tangling of the blood vessels at the end of the spinal cord. To treat AVM, physicians use a combination of embolization (closing off blood vessels) and microsurgery.

Intra-arterial T-PA for Acute Stroke

During this procedure, a thin, flexible catheter is inserted into an artery in the groin. It is then guided up to the blood clot in the brain so the clot can be removed.
