A case of endovascular embolization of BA-SCA saccular aneurysm associated with SCA fusiform aneurysm

A 52-year-old male who complained of a headache was admitted to our hospital. A left basilar artery-superior cerebral artery (BA-SCA) saccular aneurysm and a left distal SCA fusiform aneurysm were detected. As the high position BA-SCA aneurysm was difficult to treat with direct surgery, coil embolization was selected. By inserting a microcatheter into the left SCA, we were able to examine the collateral flows of the distal SCA (occlusion test). After the occlusion test, the BA-SCA aneurysm was totally embolized with detachable coils including the orifice of the left SCA. Using these strategies, we were able to safely treat both aneurysms after the collateral flow of the distal SCA was evaluated by endovascular surgery.
