Surgical Treatment of Venous Varix Associated with a Cerebral Developmental Venous Anomaly

Venous varix occurring with a developmental venous anomaly is a rare disease entity that may be found incidentally by conventional cerebral angiography. Developmental venous anomaly (DVA) without venous varix has a normal physiology, and thus, in most cases treatment is not necessary. Although most varices with venous anomalies are known to be clinically silent but if hemorrhage from increased venous pressure or occurs, then a critical intracranial hemorrhage (ICH) may follow. But there is no guideline about conservative and surgical treatment. The authors present their surgical experience of 35-year-old man with a large venous varix occurring with DVA and rationale for surgical treatment.
