Abstract

Flow diversion is a novel treatment for brain aneurysms that works by redirecting blood flow away from the aneurysm. By placing a stent in the parent vessel that covers more of the opening to the aneurysm with mesh than traditional stents, blood flow is redirected away from entering the aneurysm. The blood within the aneurysm then stagnates and undergoes thrombosis. Over time, a new endothelium develops across the neck, thereby reconstructing the parent vessel and curing the aneurysm. There are several known rare complications associated with this treatment modality and a growing understanding of how to avoid them. For one, ischemic events can occur and are related to either thromboembolism or perforator vessel occlusion. Also, hemorrhagic events can occur unpredictably at distant sites, or even from the target aneurysm. Finally, aneurysm persistence following treatment is an infrequent event but can occur and place patients at risk for future aneurysm rupture. Flow diversion is an effective method to treat many types of brain aneurysms, and a focus on complication avoidance is necessary to make it an even safer option for patients.
