Cortical versus Pial Venous Drainage in Dural Arteriovenous Fistula
directly related with intracerebral hemorrhage in dural arteriovenous fistula (DAVF) because the cortical vein anatomically exists in the subarachnoid space [1]. Hemorrhage is the most serious event in cranial DAVF. Cortical venous reflux (CVR) has been known as a prognostic risk factor for hemorrhage in cranial DAVF [2]. Hemorrhage risk is related to lesion location, sex and cortical venous re...

متن کاملEvaluation of Venous Drainage Patterns for Skull Base Meningioma Surgery
The evaluation of venous drainage patterns prior to surgery for skull base meningioma is important owing to their deep location and the vulnerability of surrounding vascular structures. In recent years, the microsurgical skull base approach has matured as a surgical technique, making it an important option for reducing complications related to skull base meningioma surgery. In addition, knowled...
متن کاملAnomalous pulmonary venous drainage.
Cases of drainage of the pulmonary veins into the right side of the heart have been well summarized by Brody (1942). He reported 38 cases of complete, and 68 cases of partial, drainage of the pulmonary veins into the right atrium or its tributaries.
