Case ReportsBilateral supratentorial epidural hematomas: a rare complication in adolescent spine surgery.
A 14-year-old girl presented with a rare case of spontaneous bilateral supratentorial epidural hematomas which developed rapidly following cervical surgery. The hematomas presumably resulted from dural dynamics changes secondary to cerebrospinal fluid loss and intracranial hypotension. ⋯ Spontaneous intracranial epidural hematoma is an extremely rare complication, but should be considered as a possible complication of spine surgery, especially in adolescents complicated by delayed consciousness and breathing restoration from anesthesia. This case report expands the presently known clinical spectrum of this uncommon complication.

Case ReportsSupra-diaphragmatic pituitary adenoma removed through the trans-tuberculum sellae approach. Case report.
A 59-year-old woman presented with a rare supra-diaphragmatic pituitary adenoma manifesting as a mass lesion. Her baseline data and the response of anterior pituitary hormones to the provocation test were within the normal range. ⋯ Her postoperative course was uneventful and the histological diagnosis was pituitary adenoma located in the suprasellar region. The trans-tuberculum sellae approach is a less invasive method to remove pituitary adenoma located in the suprasellar region.

Retrospective analysis of hinge technique for head trauma or stroke.
Hinge technique is a new method for cerebral decompression that allows the bone flap to move outward in response to brain swelling and essentially allows reconstruction of the cranial vault as a minor procedure under local anesthesia. This retrospective study assessed outcomes following the use of this new decompressive technique. During an approximately 7-year period (June 2004 to March 2011), 58 patients who had suffered head trauma or stroke underwent cerebral decompression using the hinge technique or conventional decompressive craniectomy. ⋯ Six patients in the decompressive craniectomy group and none of the patients in the hinge technique group developed bone flap infection (p = 0.02). The bone flap was removed in two cases in the hinge technique group due to low cerebral perfusion pressure as well as elevated intracranial pressure (ICP). The hinge technique with ICP monitoring was effective and safe for management for head trauma or stroke and was not associated with bone flap infection.

Clinical TrialWatertight dural closure constructed with DuraSeal TM for bypass surgery.
Superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis is a common procedure for the treatment of cerebral ischemia and is useful for cerebral aneurysms and tumors. The STA has to pass through the dura and the dura cannot be sutured tightly around the STA to prevent vessel narrowing, so subcutaneous cerebrospinal fluid (CSF) collection is common. This study analyzed the feasibility of using a synthetic dural sealant in the STA-MCA anastomosis to establish watertight closure. ⋯ Only two patients developed subcutaneous CSF collection, which was managed conservatively. The patency of the anastomosis was proven by magnetic resonance angiography in all cases, and no ischemic complication suggesting chemical spasm of the STA due to the sealant occurred. With DuraSeal(TM), watertight dural closure can be obtained easily and safely in bypass surgery.

Clinical TrialSpinal cord stimulation for the treatment of abnormal posture and gait disorder in patients with Parkinson's disease.
Patients with advanced Parkinson's disease (PD) often present with axial symptoms, including abnormal posture, postural instability, and gait disorder. Although spinal cord stimulation (SCS) is effective for pain, little is known about the effect of SCS on motor function in PD patients. The present study investigated the effect of SCS on posture and gait in 15 PD patients, 5 men and 10 women aged 63-79 years (mean 71.1 years), with low back pain and leg pain who received SCS. ⋯ Timed 10-Meter Walk tests also demonstrated that patient gait was significantly improved at 3 months and 12 months after surgery. Most advanced stage PD patients suffer considerable pain that causes abnormal posture and gait disturbance. SCS is expected to lead to both amelioration of pain and improvement of motor function in such patients.
