Abstract

Background

The Pipeline embolization device has been used successfully to treat intracranial aneurysms with difficult morphologies. However, the need for dual antiplatelet therapy has limited its use after subarachnoid hemorrhage.

Case report

A 42-year-old woman with a ruptured dissecting aneurysm of her dominant vertebral artery (V4) was successfully treated by Pipeline embolization with preservation of flow through a covered posterior inferior cerebellar artery. This strategy preserved endovascular access for the treatment of severe posterior circulation vasospasm. She was a non-responder to thienopyridine agents and was thus maintained on aspirin and heparin, which was transitioned to warfarin following ventricular drain removal. The aneurysm remains angiographically obliterated at 6 months. Despite a moribund presentation and an extended hospitalization, she has made a remarkable neurological recovery.

Conclusions

Pipeline embolization may be used to treat a ruptured dissecting aneurysm in selected cases where parent vessel preservation is paramount.
