Transvenous treatment of cranial dural arteriovenous fistulas with hydrogel coated coils Academic Article uri icon


  • Intracranial dural arteriovenous fistulas (DAVF) with cortical venous reflux may become symptomatic due to venous congestion or intracranial hemorrhage. Venous congestion in the orbit can also occur resulting in proptosis, chemosis, double vision and progressive visual loss. The transvenous approach has been used for selective disconnection of the venous drainage to eliminate the venous congestion and future risk of intracranial bleeding and/or neurological deficit. Hydrogel coated coils (HydroCoil®) expand after contact with blood causing the coils to swell up to five to 11 times a standard 10-system bare platinum coil. Due to this property, HydroCoils could have an advantage over platinum coils in the transvenous approach to embolization of DAVFs. Ten patients with symptomatic cranial DAVF underwent a transvenous embolization using HydroCoils as the only embolic agent …
