Abstract:
Hie medical records of 2 case∗ of spinal dural arteriovenous fistula (SDAVF) treated in the hybrid operating room were analyzed retrospective])- and die relevant literatures were reviewed to evaluate the clinical value of intraoperative 9pinal digital subtraction angiography (SDSA) combined with image fusion technology. Both case9 were diagnosed by spinal angiograms before operation. Both fistulas were accurately found at thoracic level and surgically disconnected in the hybrid operating room. The modified Aminoff- Loguc scores (mALS) was used to evaluate the spinal function. Intraoperative SDSAs were performed immcdiaicly after disconnections, and the fistulas were showed to be completely disappeared. The duration of intraoperative SDSAs and Image fusion for fistula localization were 70 and 60minutes respectively. No SDSA-redated complications happened. "Hie clinical symptoms of both patients improved variously during 12-14 months of follow-up. The decreasing of mALS were 6 and 5 points respectively. Our experience indicated that intraoperative SDSA combining image fusion technology was helpful for precisely localizing the fistulas of SDAVF,making their surgeries less invasive and the surgical disconnections more reliable.
