Abstract：Objective To analyze the diag nosis and microsurgery for patients with perimedullary arteriovenous fistulas (PMAVF). Methods Clinical data of 10 PMAVF patients undergoing microsurgery were analyzed retrospectively. Application value of CTA in PMAVF and the influence of microsurgery on spinal cord function were analyzed. Results The CTA results were identical with DSA results in 8 patients, and the CTA was same to DSA in determining the fistulas of PMAVF. There was 1 patient with negative CTA examination result, who was definitly diagnosed with PMAVF by DSA. One patient received only DSA examination before surgery. Postoperative spinal DSA reexamination showed that no fistula recanalization occurred in all the patients. All the patients were followed up for 6 month to 2 years and the spinal function was improved in 7, stable in 2 and aggravated in 1 patient. The Aminoff-Logue Scoring 6 months after surgery was significantly superior to preoperation (P< 0.05). Conclusions Microsurgery is an effective method for PMAVF. The early diagnosis and treatment could improve the lower limb motor and sphincter functions.
