Bi-Plane Angiography

Fort Sanders Regional was the first facility in the area to combine CT and bi-plane angiography with a full-time neurointerventional radiologist to provide our region with new, minimally invasive options for treating stroke, aneurysms and other vascular diseases in the brain. With this system, neurointerventional radiology procedures can be performed that would previously require surgery and an extended hospital stay or would have been unavailable to certain patients.

Bi-plane technology improves imaging and resolution, creating comprehensive 3-dimensional views of the blood vessels in the brain. Having a more precise picture of an abnormality makes it easier to diagnose and repair. A team of specialized technologists and nurses work to assist the performing radiologist with each procedure and all of our technologists are certified by the American Registry of Radiologic Technologists. Micro-catheters are inserted through the groin and then guided to the area of treatment to either administer medications, coil aneurysms or retrieve clots. These new procedures often have very short hospitalization, all while keeping radiation exposure to a safe minimum and without major surgery.

Bi-plane procedures include:

  • Merci clot retrieval for stroke
  • Coiling treatment for aneurysm
  • Arteriovenous Malformation (AVM) treatment
  • Angioplasty and stenting
  • Merci clot retrieval and Intra-arterial tPA

For patients who arrive in the emergency room after three hours, thrombolytics can be administered directly into the clot through a small catheter in the blocked artery. A corkscrew device, called the Merci clot retriever, can be inserted through a catheter to remove a clot in large arteries in the brain.

There is a time limitation for this treatment. Patients must get to the emergency room within 6 hours of symptom onset in order to receive intra-arterial tPA and the Merci clot retriever. 

Coiling Procedure for Aneurysms

With Fort Sanders’ new bi-plane angiography system, aneurysms can better visualized, accessed, and repaired using a revolutionary coiling procedure. A neurointerventional radiologist (a physician with expertise in both neurovascular disease and imaging) is required to perform this procedure. Fewer than 300 physicians of this specialty exist in the United States.

With the less invasive coiling technique, aneurysms are repaired using tiny metal coils which are fed through a small catheter from an artery in the leg to the brain. The coils are made of soft platinum wire and clot the aneurysm from within. The artery heals across the coils, forming a new layer of tissue.

In some cases, because of an aneurysm’s location or the patient’s medical condition, coiling may not be the best treatment. Traditional neurosurgery may be recommended. Fort Sanders Regional’s neurointerventional radiologist and neurosurgeons work together to determine the best treatment option for each patient.

Arteriovenous Malformation (AVM) Treatment

AVMs are rare congenital defects in the arteries and veins of the brain. These can bleed can cause strokes but can also be treated using similar techniques as listed above with bi-plane technology.

Angioplasty-Stenting for Narrowed and Obstructed Arteries

Some blockages inside the brain may cause stroke and cannot be treated with traditional surgery. Bi-plane technology may assist these patients.
