Endovascular therapy of a large vertebral artery aneurysm using stent and coils

Background: Endovascular therapy is becoming an increasingly popular treatm ent for cerebral aneurysms. Total angiographic occlusion of small-necked an eurysms (<4 mm) can be obtained in a high percentage of cases. The endovasc ular treatment of wide-necked or fusiform aneurysms remains a challenge wit h complete angiographic occlusion reported in <15% of cases. Case Report: W e describe the combined use of a flexible coronary stent and platinum coils to treat a wide-necked aneurysm of the distal left vertebral artery, in a patient with Grade IV subarachnoid hemorrhage. Results: The procedure was t echnically successful as the parent artery was protected by the stent while coils were deposited in the aneurysm lumen. Although angiographic aneurysm occlusion was incomplete, the dome was packed with coils. No further hemor rhage has occurred. Conclusion: Combined endovascular stent and coil therap y is a promising technique for the treatment of wide-necked cerebral aneury sms.
