Finally, we present our obser-vations on a small group of subjects presenting with asymp-tomatic sinking skin flaps, in a further effort to highlight pos-sible factors influencing the physiopathology of the syn-drome. The radiologist must be vigilant regarding the appearance of. ST is also known as “sinking skin flap syndrome” and typically occurs in the weeks to months following operation. On the basis of these data, we propose a classificationSinking skin flap syndrome, also known as syndrome of the trephined, occurs in decompressive craniectomy patients. Sinking skin flap syndrome is defined as neurologic deficits with concave deformity and relaxation of the skin flap which tends to develop several weeks to. This results in displacement of the brain across various intracranial boundaries. ” Syndrome of the trephined had an overall frequency of 10 % (43/425) following DC [25, 27, 38, 101, 103]. Teaching point: Sinking skin flap syndrome is a medical emergency that rarely complicates large craniectomy. The syndrome has also been called the “syndrome of the sinking skin flap” by Yamaura and Makino. 「外減圧後の合併症」.

After that, sinking skin flap syndrome has been reported fairly in the literature. [ 2] The spectrum of symptoms resulting from this syndrome can range from seizures, headache, neurospsychiatric disturbance, focal weakness, midbrain syndromes, [ 3] and Parkinsonian symptoms. We report our experience in a consecutive series of 43 patients diagnosed with SFS and propose a classification. The shrinkage and displacement of the brain structure is caused by the differences in intracranial pressure and exter- nal atmospheric pressure. This usually. Management is largely conservative. The procedure is thought to convert cranium from a closed to an open box, hence altering the basic pathophysiology. Cranioplasty is mostly required to treat the sinking skin flap syndrome to achieve further neurological improvement 1). Sinking skin flap syndrome or “syndrome of the trephined” is a rare complication after a large craniectomy, with a sunken skin above the bone defect with neurological symptoms such as severe headache, mental changes, focal deficits, or seizures. Therefore, in a patient with decompressive craniectomy, lumbar drainage or shunt surgery carries a risk to cause sinking skin flap syndrome (SSFS) or trephined syndrome, progressing to paradoxical. The inhibition of function in a portion of the brain at a distance from the original site of injury is known as “diaschisis. Cranioplasty is an in evitable operation conducted after decompressive craniectomy (DC). The problem was considered to have been asymptomatic sinking skin flap syndrome (SSFS). In addition he became aphasic when seated and the symptoms subsided on lying down. By convention, ST refers to the development of those symptoms that are reversible after cranioplasty . Eventually, in some cases, a significant difference between atmospheric and intra cranial. Alteration in normal anatomy and pathophysiology can result in wide variety of symptoms including altered mental status, hemodynamic instability, and dysautonomias. The characteristic phenomenon would be described as “the syndrome of the sinking skin flap, ” considering that neurological deterioration may be due solely to effect of concave deformity of the skin flap upon the underlying brain tissue. Without early identification and. Sinking skin flap syndrome (SSFS) is a rare complication of decompressive craniectomy (DC) and causes a wide range of neurological deficits. Knowing that the mechanism of SSSF has been speculated to be the result of the.

The pathophysiology of this phenomenon is not completely clear, but is felt to be related to the conversion of a closed system to an open system. It consists of a sunken scalp above the bone defect with neurological symptoms. This results in displacement of the brain across various intracranial boundaries. Sinking skin flap syndrome, also known as “syndrome of the trephined,” is an uncommon complication after decompressive craniectomy. Retrospective analysis found that those patients with sinking skin flap syndrome had significantly smaller surface craniectomy, tended to be older in age, and had a larger infarct volume. Remarkably, the brain parenchyma was more often still above. We report a unique case presenting with these complications immediately after decompressive craniectomy for severe traumatic brain injury. This is a complication that occurs in patients with large cranial defects following a DC. 2) A known cause is local in-folding of the scalp or scarring at the craniectomy site between the overlying skin and dura, which exerts direct pressure on the brain.
