기저동맥 분지부 동맥류에 대한 치료 전략

Abstract

Objective :To suggest therapeutic strategies of basilar apex aneurysms.

Methods :56 cases of basilar apexaneurysms were treated at our hospital from January 1990 to May 2011. Theywere comprised of 18 male and 38 female patients aging from 35 to 81 years old (Mean age :58.4 years old). 29 cases were treated surgically and 27 cases were treated by endovascular approach. The clinical recordswere reviewed retrospectively.

Results &Conclusion :Basilar apex aneurysm continues to be a treatment challenge because of anatomic characteristics. Though the surgical clipping is the definitive treatment of cerebral aneurysms, endovascular coiling has showed less severe complications, such as brain stem infraction than surgical clipping andmortality and morbidity of endovascular coiling cases was lower relaively than that of surgical cases in our series. Nonetheless, not all basilar apex aneurysms are amenable to endovascular approach. Neurosurgeons must be familiar with both surgical and endovascular approach and select one of them adequately.
