Abstract
This study evaluated angiographic and clinical results in patients with a dural arteriovenous fistula (DAVF) who underwent percutaneous transvenous embolization. Retrospective chart analysis and radiographic studies were performed in 23 patients (aged 11-70 yrs) with a DAVF treated with percutaneous transvenous embolization in the past five years. Lesions were located in the anterior cranial fossa, cerebellar tentorium, transverse-sigmoid sinus and cavernous sinus. All procedures were analyzed with regard to presentation, delivery, angiographical and clinical outcome. Data for 23 patients (age range, 11-70 yrs, mean age 49.5yrs) with DAVFs (cavernous sinus[ CS], n=17; transverse-sigmoid sinus, n=3; anterior cranial fossa, n=2; cerebellar tentorium, n=1) were retrospectively reviewed. The DAVFs were treated with coils or a combination with Onyx via different transvenous approaches, in 28 procedures. Cerebral angiography was performed to confirm the treatment. The mean clinical follow-up period was 22.1 months. Transvenous treatment of intracranial DAVFs can be safe and effective if various transvenous approaches are attempted. Percutaneous transvenous embolization with detachable platinum coils or a combination with Onyx is effective in the treatment of DAVFs.
Highlights
This study evaluated angiographic and clinical results in patients with a dural arteriovenous fistula (DAVF) who underwent percutaneous transvenous embolization
This study presents our experience of different transvenous embolization techniques for the treatment of intracranial DAVFs and transvenous administration of Onyx
Twenty-one DAVFs were completely embolized with detachable platinum coils or a combination with Onyx
Summary
This study evaluated angiographic and clinical results in patients with a dural arteriovenous fistula (DAVF) who underwent percutaneous transvenous embolization. Data for 23 patients (age range, 11-70 yrs, mean age 49.5yrs) with DAVFs (cavernous sinus[CS], n=17; transverse-sigmoid sinus, n=3; anterior cranial fossa, n=2; cerebellar tentorium, n=1) were retrospectively reviewed. The DAVFs were treated with coils or a combination with Onyx via different transvenous approaches, in 28 procedures. Percutaneous transvenous embolization with detachable platinum coils or a combination with Onyx is effective in the treatment of DAVFs. DAVFs represent 10 to 15% of intracranial arteriovenous malformations . DAVFs with retrograde cortical drainage often require an anatomic cure They can be treated with different modalities, such as endovascular procedures with transvenous and transarterial , surgery , gam- 1,11,17,19-25,33,35,37,42,43,49-57. Clinical follow-up periods for this group ranged from two to 36 months (mean, 13 months)
