Rupture of a Cervical Arteriovenous Fistula Associated with Neurofibromatosis Type 1. A Case Report.
We present a case report of a ruptured arteriovenous fistula (AVF) associated with neurofibromatosis type 1 (NF1). A 39-year-old man with NF1 suddenly developed a huge hematoma in the right neck region. Right vertebral and right extracarotid angiograms disclosed dilated, tortuous vessels and blood pooling. Therefore, superselective embolization using polyvinyl alcohol (PVA) particles and microcoils was performed to obliterate the AVF.
