Endovascular-Vascular Course for Residents-Making Sense of AVM Surgery

Video Transcription

Video Summary

In this video, Dr. Spetzler discusses his experience and strategies for surgically treating arteriovenous malformations (AVMs). He explains that AVM surgery is more challenging to understand and plan for than aneurysm surgery. To better understand AVM surgery, he has developed a system based on his experience with over 670 cases. He categorizes AVMs into seven types based on their location in the brain, such as frontal lobe, temporal lobe, etc. Within each type, he further breaks them down into subtypes based on the surface the AVM resides on. For example, the frontal lobe has lateral, medial, basal, sylvian, and paramedian surfaces. He emphasizes the importance of understanding the anatomy, developing strategic battle plans, and recognizing the enemy in each case. He also outlines the eight steps for AVM resection, starting with exposure and ending with resection, and provides tips and tricks for each step. He encourages surgeons to study angiographic and radiographic anatomy to avoid surprises during surgery. He concludes by urging surgeons to be courageous and not shy away from AVM surgery, despite the potential risks and complications.
