Abstract:
Objective To investigate the causes,consequences and management of injuries to the draining veins after embolization of brain arteriovenous malformations(BAVMs)with ?-n-butyl cyanoacrylate (NBCA).Methods The angiographic imaging data of 189 BAVMs patients who underwent NBCA embolization were studied retrospectively.The status of the draining veins before and after NBCA embolization was observed and compared.The intracerebral hemorrhage(ICH)complications and their relation to their angiographic features were analyzed.Results Twenty-three patients out of 189 patients showed injuries to the draining venous system,including 10 low-grade injury,6 moderate injury,and 7 high- grade injury.Six patients suffered from ICH after embolization,of whom 4 patients were due to injuries of the draining veins(2 moderate and 2 high-grade).In the 3 months follow-up evaluation of 4 patients with ICH, one died,one was in vegetative state,and the other two patients suffered from residual severe or minor (1 patient for each)permanent neurological deficits.Conclusion Our findings suggest that injury of the draining veins is the major cause of ICH and may lead to serious consequences after embolization of BAVMs with NBCA.
