A new polyvinyl alcohol hydrogel vascular model (KEZLEX) for microvascular anastomosis training
Date of publication: 23-Nov-2010
Background:Microvascular anastomosis is a challenging neurosurgical technique that requires extensive training for one to master it. We developed a new vascular model (KEZLEX, Ono and Co., Ltd., Tokyo, Japan) as a non-animal, realistic tool for practicing microvascular anastomosis under realistic circumstances.
Magnetic resonance findings in sellar and suprasellar tuberculoma with hemorrhage
Date of publication: 20-Nov-2010
Background:Tuberculosis is endemic in many counteries like India. It can infect any site in the central nervous system. However, islolated involvement of the sellar and suprasellar region is rare. Sellar tuberculoma with hemorrhage is even more rare. We present magnetic resonance (MR) findings in case of sellar and suprasellar tuberculoma with hemorrhage.
Adhesion of rhomboid lip to lower cranial nerves as special consideration in microvascular decompression for hemifacial spasm: Report of two cases
Date of publication: 18-Nov-2010
BackgroundAlthough the rhomboid lip is a well-known structure constructing the foramen of Luschka, less attention has been directed to the structure for posterior fossa microsurgeries. The authors report two cases of the hemifacial spasm (HFS) with a large rhomboid lip, focusing on the importance of the structure during microvascular decompression.
Prophylactic retrievable inferior vena cava filters in spinal cord injured patients
Date of publication: 30-Oct-2010
Background:Pulmonary embolus (PE) secondary to deep vein thrombosis (DVT) continues to be a major source of morbidity and mortality in trauma populations. Patients with cervical spinal cord injury (SCI) are particularly susceptible to developing this complication. Non-invasive methods of preventing SCI, such as lower extremity compression devices and anticoagulation, do not confer complete protection against DVT. Retrievable inferior vena cava filters (IVCFs) offer the advantage of both providing protection against PE and avoidance of long-term complications such as DVT, if removed in a timely fashion. Our goals in this study were to identify complications related to IVCF insertion and also to determine if prophylactic insertion of IVCF is effective in preventing PE in spinal cord injured patients.
Research-retreat-recovery: A potential model for organization and completion of research projects. Experience from a neurosurgery department in a developing country
Date of publication: 30-Oct-2010
Background:In the current era of biomedical research, it is imperative that every research study at an institution is properly organized, and frequently audited to streamline efforts and maintain standards. Recently, a research retreat was organized by the Section of Neurosurgery at Aga Khan University Hospital, Karachi, Pakistan, and following that a recovery team was made with the aim of recovering “lost in translation” research projects. In the realm of our experience, the current model is being proposed as a means for organization of departmental research.
Use of sodium fluorescein in skull base tumors
Date of publication: 30-Oct-2010
Objective:The authors present this study using sodium fluorescein (SF) to enhance skull base tumors by performing a quantitative digital analysis of tumor enhancement. The purpose of this study is to observe the grade of SF enhancement by the tumors.
Is sagittal sinus resection in falcine meningiomas a factor of bad surgical outcome?
Date of publication: 25-Oct-2010
Objective:Meningiomas arising purely from the falx below the longitudinal sinus represents a surgical challenge for the neurosurgeon. The authors discuss the new aspects of surgical details that may avoid complications and determine the prognosis.
Delayed cerebral radiation necrosis following treatment for a plasmacytoma of the skull
Date of publication: 25-Oct-2010
Background:Cerebral radiation necrosis is a relatively common complication of radiation therapy for intracranial malignancies which can also rarely be encountered after radiation of extracranial lesions of the head and neck. We present the first reported case of cerebral radiation necrosis in a patient who underwent radiation therapy for a plasmacytoma of the skull.
