Parent vessel occlusion for P2 dissecting aneurysms of the posterior cerebral artery.

AbstractBACKGROUND:
Dissecting aneurysms of the PCA are difficult to treat with preservation of the parent arteries. We report the clinical and angiographic outcome for 8 patients with dissecting aneurysms located at the P2 segment of the PCA.
METHODS:
In the past 5 years, 8 patients, 2 female and 6 male, presented to our institution with P2 dissecting aneurysms of the PCA and were treated endovascularly. The age of our patients ranged from 4 to 58 years, with a mean age of 34.4. Of the 8 patients, 5 had subarachnoid and/or intracerebral hemorrhage upon presentation. Two patients with P2 dissecting aneurysms presented with mild hemiparesis and hypoesthesia; 1 patient with a large dissecting aneurysm complained of headaches.
RESULTS:
Eight patients with P2 aneurysms of the PCA underwent PVO. Parent vessel occlusions were performed with detachable coils. No patient developed neurologic deficits.
CONCLUSION:
P2 dissecting aneurysms can be treated with PVO in the cases in which selective embolization of the aneurismal sac with detachable platinum coils or surgical clipping cannot be achieved.
