Sinking skin flap syndrome is a rare syndrome leading to increased intracranial pressure, known to neurosurgeons, yet uncommon and hardly ever reported in trauma patients. ” In the presented case, these neurologic deficits may be a consequence of reduced cerebral blood flow 1 and a disturbed metabolism due to direct cortical compression of the sinking cranioplasty and the secondary diaschisis at different. 127. 3. Nonetheless, full healing of the skin flap was evidentSinking Skin Flap Syndrome. 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. Sinking skin flap syndrome, paradoxical herniation (more on these below). Introduction: The "Motor Trephine Syndrome (MTS)" also known as the "Sunken brain and Scalp Flap Syndrome" or the "Sinking Skin Flap Syndrome (SSFS)" or the "Syndrome of the trephined" is an unusual syndrome in which neurological deterioration occurs following removal of a large skull bone flap. Although changes in cerebrospinal fluid (CSF) hydrodynamics, cerebral blood flow and brain metabolism have been described as partial aspects of the pathophysiology, a. These 2 syndromes illustrate the paradigm shift of the indications for cranioplasty, which have evolved from cosmetic. Teaching point: Sinking skin flap syndrome is a medical emergency that rarely complicates large craniectomy. Sinking skin flap syndrome (SSFS) is a rare neurological complication in patients with traumatic haemorrhage, stroke or cerebral oedema who undergo decompressive craniectomy to relieve increased intracranial pressure. (38%). . AU Sarov M, Guichard JP, Chibarro S. Disabling neurologic deficits, as well as the impairment of. It results from the pressure difference between the atmospheric pressure and the intracranial pressure causing the brain to shift inward at the craniectomy site. If the defect is closed by a prosthetic covering then it is known as a cranioplasty. Although frequently presenting with aspecific. Sinking skin flap syndrome (SSFS) or "syndrome of the trephined" is a rare complication that can occur after decompressive craniectomy. Zusammenfassung. or. Clinical presentation May range from asymptomatic or mono symptomat. The prevalence and characteristics of SSF syndrome after hemicraniectomy for malignant infarction of the. Europe PMC is an archive of life sciences journal literature. Stroke. In the present case, sensorimotor paresis promptly reversed after cranioplastic repair and MR brain perfusion. Europe PMC is an archive of life sciences journal literature. No. Europe PMC is an archive of life sciences journal literature. Brain tumor. Sinking skin flap syndrome (SSFS) or "syndrome of the trephined" is a rare complication that can occur after decompressive craniectomy. Syndrome of the trephined (ST) is a post-craniectomy complication. Syndrome of the trephined (sinking skin flap syndrome) with and without paradoxical herniation: a series of case reports and review. 「外減圧後の合併症」. This results in displacement of the brain across various intracranial boundaries. Besides, the traditional managements reducing the intracranial pressure for herniation may exacerbate paradoxical herniation, therefore, timely diagnosis and correct treatments are significantly important. Sinking skin flap syndrome (SSFS) is a condition unique to patients who have undergone craniectomy [2]. Sinking skin flap syndrome, or syndrome of trephined, seems as a DC-related complication in the first several weeks and months after DC.
