Characteristics and endovascular treatment of aneurysms of posterior cerebral artery
Background : Aneurysms of the posterior cerebral artery (PCA) are a
distinct rarity and present with some peculiar morphologic features and
specific clinical findings. These aneurysms can be managed
endovascularly with good results. Objective : To evaluate the clinical
features and endovascular management of PCA aneurysms. Material and
Methods : Between 2000 and 2008, we treated 24 patients (14 male and 10
female; mean age: 36 years) with PCA aneurysms. Clinical presentations,
radiologic images, and endovascular management were reviewed. Results :
There were 11 saccular aneurysms, including 4 giant or large aneurysms,
and 13 dissecting aneurysms, including 11 giant or large aneurysms. Of
the 24 patients, 13 presented with hemorrhage and 6 with neurologic
deficits. Five patients presented with headaches without any neurologic
deficits. Parent vessel occlusion was performed in 12 patients,
selective coil embolization was performed in 11 patients, and 1 patient
conservatively. Eighteen patients had a good recovery, 5 had a moderate
disability (one with 1 visual deficit after the treatment) related to
hemorrhage, vasospasm, or infarction before aneurysm trapping, and 1
patient died because of rebleeding. The conservatively treated patient
made a good recovery. Conclusion : PCA aneurysms have specific clinical
characteristics compared with aneurysms located elsewhere. Endovascular
technique can achieve good outcomes despite the aneurysmal site and
size
