Abstract

Blood blister-like aneurysms (BLAs) are rare lesions, associated with diffuse subarachnoid hemorrhage (SAH). BLAs tend to rebleed quickly after first bleeding and must be treated as an emergency. Acute treatment is challenging using surgical and endovascular approaches due to the fragile aneurysm wall and small sac. Flow-diverter stents (FDSs) may offer a new option for the treatment of difficult small aneurysms. We describe a case of a ruptured BLA on the anterior communicating artery (AComA) treated in the acute phase of SAH by endovascular exclusion of the AComA with deployment of two FDSs in the A1/A2 junctions of both anterior cerebral arteries (ACAs). A 61-year-old man was admitted for diffuse SAH with a focal interhemispheric hematoma. Angiography revealed multiple arterial wall irregularities on the AComA and both ACAs. We performed an endovascular shunt of the AComA by deploying two FDSs in both A1/A2 junctions. Immediate control injections confirmed flow diversion in the A1/A2 segments of the ACAs with decreased blood flow in the AComA. The patient's course in hospital was uneventful. A three-month follow-up angiogram confirmed complete exclusion of the aneurysms, complete exclusion of the AComA, and patency of the tw...Continue Reading
