What data has led to an increasing tendency toward coiling ruptured posterior circulation aneurysms?
A meta-analysis revealed that the mortality from coiling of a basilar bifurcation aneurysm was 0.9%, and the risk of permanent complications was 5.4%. More recently, with regard to treatment of posterior circulation aneurysms, the mortality and morbidity in 112 ruptured aneurysms was 3.7% and 9.4%, respectively. These data have led to an increasing tendency toward coiling ruptured posterior circulation aneurysms.
