A spinal cordectomy is a treatment option for several disorders of the spinal cord like post-traumatic syringomyelia, spinal cord tumor and myelomeningocele. We have done a systematic analysis of all reported cases of spinal cordectomy to investigate the possible outcomes and complications. A PubMed search was performed for literature published from 1949 to 2015 with search words "spinal cordectomy", "spinal cord transection" and "cordectomy for malignant spinal cord tumors" to select articles containing information about the indication, outcome and complication of spinal cordectomy performed for diverse etiologies...

OBJECTIVE The anterior temporal artery (ATA) supplies an area of the brain that, if sacrificed, does not cause a noticeable loss of function. Therefore, the ATA may be used as a donor in intracranial-intracranial (IC-IC) bypass procedures. The capacities of the ATA as a donor have not been studied previously. In this study, the authors assessed the feasibility of using the ATA as a donor for revascularization of different segments of the distal middle cerebral artery (MCA). METHODS The ATA was studied in 15 cadaveric specimens (8 heads, excluding 1 side)...

BACKGROUND: Arachnopathy following meningitis has been described in the setting of chronic spinal arachnoiditis and more recently as shunt-related progressive myelopathy due to meningeal thickening. CASE DESCRIPTION: We describe an atypical case of a patient who presented with chronic arachnopathy 5 decades after an episode of meningitis. We also review the literature concerning arachnopathies occurring in the context of early childhood meningitis. Although our case bore clinical and radiologic similarities to chronic spinal arachnoiditis and shunt-related progressive myelopathy, time to symptom onset, intraoperative findings, pathophysiology, and surgical outcome set it apart from both conditions...

BACKGROUND: Trigeminal neuralgia is a common entity which is managed by neurosurgeons in day to day practice. Up-till now many treatment options have been adopted for it but micro-vascular decompression is much impressive in terms of pain control and recurrence rate in all of them. The objective of study was known the efficacy of micro vascular decompression for idiopathic trigeminal neuralgia by using muscle patch in terms of immediate pain relief. METHODS: This descriptive study was carried out in Neurosurgery Department lady reading hospital, Peshawar from January 2010 to December 2012...

Intradural disc herniation is a very rare condition, and multiple intradural disc herniations have not been reported to date. The latter may be confused with intradural extramedullary (IDEM) spinal tumors. Here, we report a case of multiple intradural disc herniations masquerading as multiple IDEM tumors and review the relevant literature. We retrospectively reviewed the patient's medical chart, reviewed the intraoperative microscopic findings, and reviewed of PubMed articles on intradural disc herniation. The masses considered to be IDEM tumors were confirmed to be multiple intradural disc herniations...

BACKGROUND: The tortuous vertebrobasilar artery (TVBA) often causes neurovascular conflicts in patients with trigeminal neuralgia (TN) and hemifacial spasm (HFS). Implementation of microvascular decompression (MVD) in these circumstances is hindered due to stiffness of the enlarged and dilated arteries and is often accompanied by poor outcomes. The surgical strategy in cases of trigeminal neuralgia and hemifacial spasm associated with the TVBA should be clarified in order to achieve good outcomes...

BACKGROUND: Trigeminal Neuralgia (TGN) is the most frequently diagnosed type of facial pain. In idiopathic type of TGN it is caused by the neuro-vascular conflict involving trigeminal nerve. Microvascular decompression (MVD) aims at addressing this basic pathology in the idiopathic type of TGN. This study was conducted to determine the outcome and complications of patients with idiopathic TGN undergoing MVD. METHODS: In a descriptive case series patients with idiopathic TGN undergoing MVD were included in consecutive manner...

BACKGROUND: Arachnoiditis ossificans (AO) is a rare disorder that was differentiated from leptomeningeal calcification by Kaufman and Dunsmore in 1971. It generally presents with progressive lower extremity myelopathy. Though the underlying etiology has yet to be fully described, it has been associated with various predisposing factors including vascular malformations, previous intradural surgery, myelograms, and adhesive arachnoiditis. Associated conditions include syringomyelia and arachnoid cyst...

PURPOSE: Syringomyelia is a misleading disease since the problem always lies elsewhere. Arachnoiditis, because it is radiographically difficult to discern, is an especially insidious cause. To better guide selection from among surgical treatment options for syringomyelia, we reviewed our case series of patients without Chiari malformation or spinal injury. METHODS: Excluding syringomyelia due to Chiari malformation, spinal cord injury, and tumors, 32 patients (mean age 44 years) were operated on between 1995 and 2013 and followed up for a mean of 53...

The purpose of this study was to investigate the behavior of platelets (rolling and adhesion) in cerebral microvessels of angiotensin II type-2 receptor-knockout (AT2RKO) mice after transient bilateral carotid artery occlusion using intravital fluorescence microscopy. Twenty AT2RKO mice, consisting of 11 mice in the sham group and 9 mice in the ischemia reperfusion group (reperfusion after 15 min of bilateral, total carotid artery occlusion) were used in this study. The hole traversed the bone and dura mater, but arachnoid, pia mater, and cerebral parenchyma were preserved...

PURPOSE: Spinal surgery in a previously irradiated field carries increased risk of perioperative complications, such as delayed wound healing or wound infection. In addition, adhesion around the dura mater is often observed clinically. Therefore, similar to radiation-induced fibrosis--a major late-stage radiation injury in other tissue--epidural fibrosis is anticipated to occur after spinal radiation. In this study, we performed histopathologic assessment of postirradiation changes in the spinal dura mater and peridural tissue in mice...

INTRODUCTION: Cerebral arteries innervated by several systems contribute to the control of cerebral blood flow. Subarachnoid hemorrhage causes acutely developed vasospasm by various mechanical and neurochemical mechanisms, cranial parasympathetic nerve ischemia, and related stellate ganglion overdischarges. Dilatatory sensory fibers of cranial parasympathetic nerves and vasospastic fibers of stellate ganglions have a vasoregulatory effect on the cerebral arteries The aim of this study is to investigate the effect of sympathectomy on vasospasm of the middle cerebral artery...

Epidural blood patching is an effective treatment for postdural puncture headache but has potential risks. Arachnoiditis is a very rare disabling condition and few cases have been described following an epidural blood patch. We present a case of chronic adhesive arachnoiditis in a parturient treated with a repeat epidural blood patch. A healthy 29-year-old woman had an accidental dural puncture following epidural insertion during labour. Initial treatment of postdural puncture headache with an epidural blood patch was ineffective and was therefore repeated...

BACKGROUND: Postoperative subdural fluid collection sometimes occurs after clipping of cerebral aneurysms. Arachnoid plasty is used to prevent such postoperative complications; however, the optimal materials for arachnoid plasty remain unclear. In this study, we aimed to clarify the optimal materials for arachnoid plasty and report our experience of arachnoid plasty after clipping of unruptured aneurysms. METHODS: In an in vitro experiment, adhesive strengths of three materials permitted for use in the intradural space, such as collagen sheets, gelatin sponge, and oxidized cellulose sheets, were measured by assessing their water pressure resistance...

BACKGROUND: Arachnoid cysts and meningeal membranes are among the differential diagnostic considerations of extra-medullary causes of thoracic myelopathy. In this case series of 7 patients, we present compressive meningeal membranes mimicking dorsal arachnoid cyst. The propensity of the meningeal membranes for the dorsal aspect of upper thoracic spine may reflect derangements of the septum posticum. OBJECTIVE: To provide the spectrum of imaging appearances and clinical presentations of pathology of the septum posticum to improve imaging utilization and to better guide treatment planning...

BACKGROUND: Peritumoral edema (PTE) in skull base meningiomas correlates to the absence of an arachnoid plane and difference in outcome. In vestibular schwannomas (VS), PTE and its significance for microsurgery and outcome have never been systematically evaluated. OBJECTIVE: To evaluate whether PTE correlates with tumor characteristics, the presence of an arachnoid plane, and outcome. METHODS: A retrospective study of the institutional database...
