Endovascular-Vascular Course for Residents-Treatment of Cranial and Spinal Dural Arteriovenous Fistula

Video Transcription

Video Summary

The video content is a presentation on the thought process, treatment options, and techniques for dural arteriovenous fistulas. The presenter discusses the classification of dural fistulas based on the location of the pathology, whether in the dura or the sinus, the presence of cortical venous reflux, and the level of connection with the sinus. Type 1 fistulas, which have a direct connection from the artery to the sinus without venous reflux, are rarely treated. Treatment for type 2 fistulas involves disconnecting the pathology where there is venous reflux, either through embolization or surgery. Type 3 fistulas have preserved sinuses, and treatment requires disconnecting all the arteries from the vein. The presenter also discusses spinal dural fistulas, emphasizing the importance of understanding intercostal artery anatomy and proper identification of the level of pathology. Treatment involves blocking the connection between the intercostal artery and the interdural sleeve. The video includes examples of different treatment cases using techniques such as glue injection and onyx embolization.
