Sinking Skin Flap Syndrome as a Post-craniectomy Complication after Malignant Middle Cerebral Artery Infarct: a Case Report
摘要
One of the possible, though rare, complications of surgical decompressive craniectomy is the sinking skin flap (SSF) syndrome. This occurs in a wide variety of neurovascular, neurosurgical or neuro-traumatic conditions. Though symptoms are non-specific, this condition could be potentially fatal if not promptly identified and managed. We report a case of a 59-year-old Caucasian man admitted with a malignant middle cerebral artery (MCA) infarct who subsequently had decompressive hemicraniectomy. Following worsening consciousness and neurologic deficit associated with sunken skin 3 weeks after decompressive hemicraniectomy, an urgent repeat CT imaging revealed an SSF syndrome. A protective 3-dimensional-printed helmet, elevated bed at about 30° and an elective autologous cranioplasty improved his outcome. This is a rare case of further neurologic complication in a patient with malignant MCA infarct with decompressive hemicraniectomy. This case highlights the high suspicion index of this non-specific, potentially life-threatening condition in a patient with large territory stroke treated by hemicraniectomy.
