Although the entity is widely reported, the literature mostly consists of case reports. 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). ・感染. The term sinking skin flap syndrome assumes that the herniation in this setting results from the combined effects of brain gravity and CSF depletion in patients who have undergone decompressive craniectomy [10, 11]. 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. A diagnosis of syndrome of the trephined or “sinking skin flap syndrome were considered in them, and all of them improved after cranioplasty. 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. We considered that the cause of brain edema and cerebral hemorrhage immediately after cranioplasty could be from reperfusion, the deterioration of autoregulation, SSFS, negative pressure by subgaleal drain, venous stasis, vascular damage because of. 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. [] Although it is very rare, sinking skin flap syndrome may lead to paradoxical brain herniation, which is. 55 Sakamoto S, Eguchi K, Kiura Y, Arita K, Kurisu K CT perfusion imaging in the syndrome of the sinking skin flap before and after cranioplasty. However, several groups reported higher complication rates in early CP. 沈没皮膚フラップ症候群（SSFS）、またはトレフィン酸症の症候群は、頭蓋骨の大きな骨欠損の存在から生じる病的状態です。. 2021, Anesthesia and Critical Care. We present a 33-year-old man who experienced hemiparesis in the upright position after craniectomy. Sakamoto et al. Schorl, M. 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. (38%). Independent of the consequences of the original aetiology that necessitated the craniectomy, the bone defect alone may be the cause of the symptoms, called 'trephined syndrome' or 'sinking skin flap s 1. 9) Following. The sinking flap syndrome (SFS) is one of the complications of decompressive craniectomy (DC). 9). 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. Skip to search form Skip to main content Skip to account menu. Infrequently, neurologic deteriorations accompanied by sunken scalp may occur after DC. Introduction. The sinking skin flap syndrome is a set of neurological manifestations occurring weeks or even months after a large craniectomy performed for different reasons: severe head trauma as in the case. The “syndrome of the trephined” or “sinking skin flap syndrome” is a rare complication of a craniectomy characterized by postoperative neurological deterioration caused by cortical dysfunction of the area below the craniotomy that improves after cranioplasty. Therefore, the scalp contraction may not.
