Early postoperative administration of low-molecular-weight heparin (LMWH) to prevent thromboembolic events in patients with chronic subdural hematoma (CSDH) is controversial. Our goal was to investigate impact of early postoperative LMWH administration on recurrence rate of CSDHs. ⋯ Our data provide preliminary evidence that early postoperative administration of LWMH does not increase risk of clinically relevant recurrence of CSDHs.

The goal of treatment for spinal arteriovenous lesions is to completely obliterate the shunt. In our institution, intraoperative digital subtraction angiography and intraarterial injection of contrast agent have been used to accurately identify the site of arteriovenous shunts. We describe the intraoperative digital subtraction angiography and intraarterial dye injection procedures and how they may improve surgical outcomes. ⋯ Intraoperative digital subtraction angiography and intraarterial dye injection are useful tools for management of spinal arteriovenous lesions.

Intracranial hemangiopericytoma is a rare tumor with high recurrence rate. We analyzed adverse factors for recurrence and survival of patients with hemangiopericytoma. ⋯ This study revealed risk factors for PFS and overall survival to predict outcomes and determine treatments. GTR was attempted as frequently as possible, and PRT was recommended for patients with non-GTR or recurrence to improve tumor control.

Traditional endoscopic anterior cranial base resection involves the total removal of the ethmoidal cells, including the middle and superior turbinates. This is associated with increased volume of the nasal cavity postoperatively, with increased crusting and permanent change of the nasal airflow. Here we provide a step-by-step description of the technique and evaluate the feasibility of the superior ethmoidal approach for anterior cranial base resection with maximum exposure of the anterior cranial base while keeping the middle turbinates, uncinate processes, and ostiomeatal complexes intact. ⋯ The endoscopic superior ethmoidal approach for anterior cranial base resection is a feasible and safe approach that maximizes preservation of the nasal structures while providing optimal access to the anterior skull base. It can be used in pathologies that involve the anterior cranial base and do not involve the nasal structures.

A new sling technique in cervical radiculopathy due to vertebral artery loop compression : Case Report.
A 52-year-old woman had a 20-month history of progressive radiating pain in the left arm and numbness on C7 dermatome. ⋯ The patient's radiculopathic symptoms were improved and especially the aggravated pain by left head rotation subsided dramatically.
