Treatment of BBAs is currently challenging and remains difficult despite improvement of microsurgical technique and advancement in endovascular technologies. Therapeutic options are reconstructive and deconstructive open surgeries or endovascular procedures. However, there is a lack of consensus about optimal treatment. We report a case of 38-year old woman with subarachnoid hemorrhage due to a ruptured BBA successfully treated with placement of an endovascular flow-diverting stent.
