[Application of hybrid operating room in the treatment of spinal dural arteriovenous fistulas].

ABSTRACT

Objective: To explore the experience in the treatment of spinal dural arteriovenous fistulas with application of hybrid operating room. Method: A retrospective analysis was performed among 22 patients with spinal dural arteriovenous fistulas admitted to Department of Neurosurgery of Tianjin Medical University General Hospital who received operation in the hybrid operating room from March 2011 to February 2016. Modified Aminoff-Logue scores (ALS) for myelopathy was used to evaluate the spinal function.All the 22 patients were followed up 6-12 months after the operation. Result: All the patients were diagnosed by spinal digital subtraction angiography (DSA). The modified ALS pre-operation and post-operation 6 months were (4.7±1.8) and (2.0±1.5), respectively, with significant difference (P<0.01). There were 15 cases with mild dysfunction, 6 cases with moderate dysfunction, severe dysfunction in 1 case before operation.Fifteen cases were cured, 4 cases improved, 1 case had no change after 6 months follow-up.The improvement rate was 95.45%. Conclusion: The application of hybrid operating room in the treatment of spinal dural arteriovenous fistulas achieves good outcome and provides a convenient and effective approach, which embodies the idea of precision medicine.
