Intra-operative ultrasound for spinal dural arteriovenous fistulas: A simple technique for surgical reassurance.

BACKGROUND

Spinal dural arteriovenous fistulas (DAVFs) are the most common vascular malformations of the spine. Whilst surgical disconnection remains the mainstay of treatment, intraoperative localisation and verification of complete disconnection of the DAVF can be challenging.

OBJECTIVE

To describe the utility of intraoperative ultrasound (IOUS) as a simple, cost-effective, and user-friendly adjunct to ensure surgical success.

CONCLUSION

Used in conjunction with established methods, IOUS provides real-time surgical reassurance and helps confirm the complete disconnection of the DAVF.
