Abstract:
The dissecting aneurysms of the posterior cerebral circulation arise most commonly from the vertebral artery and occasionally extend to the posterior inferior cerebellar artery(PICA). The dissecting aneurysm localized in the PICA without involving the vertebral artery is rare. We present a PICA dissecting aneurysm that had kaleidoscopic clinical course of bleeding, occlusion, and recanalization before the surgery. The patient had serial follow-up angiograms based on significant changes of clinical status. The patient successfully underwent microsurgical trapping with clips for the dissecting aneurysm and showed neurological improvement.
