2018 AANS Annual Scientific Meeting-Planning Microsurgical Treatment of AVMS

Video Transcription

Video Summary

In this video, Francisco Gonzalez Llanos from Spain discusses the planning of microsurgical treatment for AVMs (arteriovenous malformations). He emphasizes the importance of preparing for worst-case scenarios and mastering all potential complications before surgery. While microsurgery is one treatment option, observation, embolization, and radiosurgery are also available. Llanos presents two cases, one where surgery was chosen over endovascular treatment, and another where a combination of embolization and radiosurgery was used. He highlights the importance of understanding the natural history of AVMs and identifies bleeding risk factors such as arterial and venous aneurysms, size, and location. Llanos also discusses the importance of assessing preoperative studies, including angiography, CT, CTA, and MRI. He concludes by discussing the complications related to feeding arteries, venous drainage, and the nidus of AVMs, highlighting the need for careful vessel control during surgery. The video ends with a brief discussion on the challenges of large AVM surgeries and the potential for staging the surgery if necessary.
