Secondary Clinical Deterioration after Successful Embolization of a Spinal Dural Arteriovenous Fistula: a Plea for Prophylactic Anticoagulation

摘要

We present a case of delayed aggravation of initially-resolved symptoms in a patient after successfid embolization of a T5 spinal dural arteriovenous (AV) fistula with N-butyl cyanoacr-ylate. The symptoms were attributed to venous thrombosis and resolved with systemic anticoagulation after five days of treatment. Although the most adequate treatment for preventing venous thrombosis after spinal dural AV fistula is not known, we describe this patient as a case for more aggressive prophylactic anticoagulation measures in the immediate post-embolization time period.
