Some stroke patients may benefit from cerebral angioplasty and stent placement

The remaining two groups of patients were ineligible for IVT and received either revascularization treatment or received no further therapy. Of the 31 patients who underwent angioplasty and stent placement, 14 (45.2 percent) achieved a favorable outcome. Of the 25 patients who received no therapy, two (8 percent) had a favorable outcome.

To perform the revascularization procedure, the physicians used an imaging technique called digital subtraction angiography to visualize the blood vessels and a guide wire to maneuver a balloon-tipped catheter to the location of the blockage in the middle cerebral artery. Once the balloon was inflated, deflated and withdrawn, a stent was inserted to help the artery remain open. Patients with a favorable three-month outcome following the procedure were able to live independently and perform normal daily activities.

"We demonstrated that in patients with middle cerebral artery blockage after IVT failure or for whom IVT is contraindicated, revascularization with stents is superior to providing no further therapy," Dr. Roubec said.
