Abstract
Objective To explore the surgical techniques for rare blood blister - like aneurysm (BBA) in the superior segment of clinoid process of internal carotid artery. Method The clinical data of seven cases of BBAs were studied. The separation of pia mater of the frontal pole was performed. The parent artery was blocked temporarily during the surgery. Sculpture type was adopted to directly dissociate the continuation part between the aneurysm neck and parent artery to get a small space enough for incarceration of aneurysm without exposure of the entire aneurysm. One incarceration of the lesser curvature - like aneurysm clip was specially performed to temporarily isolate the parent artery in the case of avulsion of aneurysm neck,to incarcerate the aneurysm root including the continuous part of parent artery wall in a nonfilling state. Results There were 6 cases of complete recovery after operation, 1 case of large area infarction of hemicerebrum after 2 weeks of operation resulting in hemiplegia and dementia Conclusions Special surgical techniques could reduce the surgical risk for BBA and improve curative rate.
