Sinking skin flap syndrome, resulting from decompressive craniectomy, is defined as a series of neurologic symptoms with skin depression at the site of cranial defect. Following an inner ellipse of the previous DC-surgery scar could contribute in most cases to the preservation of the vascular perfusion even if an incision outside of the ellipse might be needed in certain settings such as sinking skin flap syndrome (SSFS). Sinking skin flap syndrome (SSFS) or paradoxical herniation (PH) is a rare complication and sporadically occurs in patients after DC. It results from an intracerebral hypotension and requires the replacement of the cranial flap. Sinking Skin Flap Syndrome, a Rare Complication of Craniectomy J Belg Soc Radiol. The sinking flap syndrome (SFS) is one of the complications of decompressive craniectomy (DC). The neuro-intensive care team should be prepared to diagnose and treat a spectrum of decompressive craniectomy complications including: cerebral contusions, infections, seizures, intra- and extra-axial hemorrhages and fluid collections, sinking skin flap syndrome or syndrome of the trephined, paradoxical herniation, and external brain. The first case of sinking skin flap syndrome was reported by Yamamura et al. Neurologic. However, several groups reported higher complication rates in early CP. Europe PMC is an archive of life sciences journal literature. Its pathophysiology remains debatable, however cranioplasty may decrease the symptoms of SSFS by reducing the direct effect of atmospheric pressure on the brain and allowing the. Although changes in cerebrospinal fluid (CSF) hydrodynamics, cerebral blood flow and brain metabolism have been described as partial aspects of the pathophysiology, a. With increasing numbers. The purpose of our work was to identify radiological signs and imaging biomarkers of the ST. Thieme E-Books & E-Journals. Sinking skin flap syndrome, paradoxical herniation (more on these below). 7. It seems logical that longer times-to-cranioplasty would promote the neurologic compromise associated with the syndrome of the sinking skin flap [4, 11, 13, 14]. Zusammenfassung. Patients with SSF syndrome had a smaller surface of craniectomy (76. Sinking skin flap syndrome in the multi-trauma patient: a paradoxical management to TBI post craniectomy. The prevalence and characteristics of SSF syndrome after hemicraniectomy for malignant infarction of the. Full-text review yielded 11 articles discussing SoT and reconstructive techniques or. The neurological status of the patient can occasionally be strongly related to posture. Upright computed tomography (CT) before cranioplasty showed a remarkable shift of the brain compared to supine CT. We report a case of syndrome of the trephined that. The neuro-intensive care team should be prepared to diagnose. This kind of herniation with an uncommon mesencephalon compression is one of the most serious sinking skin flap syndrome (SSFS). The aim of the procedure was to improve cosmesis and protect the brain and avoid sinking skin flap syndrome which is a rare complication of decompressive craniectomy characterized by a sunken skin flap, neurological deterioration, and paradoxical herniation of the brain. A 77-year-old male patient with an acute subdural hematoma was treated using a hemicraniectomy. Background and Purpose— “Sinking skin flap” (SSF) syndrome is a rare complication after large craniectomy that may progress to “paradoxical” herniation as a consequence of atmospheric pressure exceeding intracranial pressure. Europe PMC is an archive of life sciences journal literature. We report a case of the patient who underwent an autologous cranioplasty to treat SSFS that developed intracerebral hemorrhage infarction. Sinking skin flap syndrome is defined by a series of neurological symptoms with skin depression at the site of cranial defect.
