Sinking skin flap syndrome in a patient with giant thrombosed posterior cerebral artery aneurysm: A case report

Abstract

Sinking skin flap syndrome is a rare complication following decompressive craniectomy. The pathogenesis is based on disturbed cerebral autoregulation and as a consequence dicreased CBF and cerebral metabolism. This results in neurologic disturbances, i. e. mental changes and focal deficits. The authors present the patient who developed the motor trephine syndrome after decompressive craniectomy following complicated giant posterior cerebral artery aneurysm clipping.
