This study evaluated the clinical outcomes following venous ligation for the treatment of @entity2457 ( @entity2457 ) with leptomeningeal or cortical venous drainage. The authors conducted a single-centre, retrospective study of 15 @entity1 with @entity2457 treated consecutively between 1990 and 2000. There were eight female @entity1 of mean age 60 years (range 36-71). Eight @entity1 presented with @entity548 , two with mass affect, two with @entity10 , one with @entity410 and two @entity1 were asymptomatic. Four @entity292 were located in the petrosal region, three at the torcula, three in the transverse sigmoid region, three in the parasagittal region and two at the foramen magnum. Leptomeningeal or cortical veins drained all @entity2457 . Eight @entity1 underwent preoperative embolization of the arterial feeders. @entity1211 resulted in obliteration of all @entity292 confirmed by direct visualization of the thrombosed veins and/or radiographic follow up. Mean follow up period was 37 months with a range of 1-112 months. All symptomatic @entity1 improved and there was no surgical morbidity. These results indicated that venous ligation to obliterate @entity2457 with leptomeningeal or cortical drainage is safe and effective. With appropriate neuroradiological diagnosis and preoperative neuroendovascular intervention, this technique resulted in obliteration of @entity2457 in 15 @entity1 without significant morbidity.
