ObjectiveTo summarize the experience in microsurgical resection of cervical spinal cord arteriovenous malformation (AVM).MethodsSix patients undergoing microsurgical resection of cervical intramedullary AVM in the Third Affiliated Hospital of Sun Yat-sen University, China, between March 2005 and March 2015 were reviewed retrospectively, and their clinical manifestations, imaging data, surgical treatment, and results of long-term follow-up were analyzed.ResultsOf the 6 patients who underwent AVM resection, 2 had compact AVMs and 4 had diffuse AVMs. All 6 patients were reexamined with spinal magnetic resonance imaging within 48 hours after surgery, and 1 patient was examined with digital subtraction angiography. The average patient age was 40.7 ± 10.4 years (range, 29-60 years). Three patients had chronic onset, of whom 2 developed sensory disturbances and 1 had muscle weakness. The other 3 patients had acute onset, including 1 with sudden quadriplegia, 1 with idiopathic severe headache and altered consciousness, and 1 with idiopathic neck pain. The average duration of follow-up was 48.5 ± 38.9 months (range, 15-119 months). One patient experienced complete recovery, and the other 5 patients showed improvement. No patient exhibited deterioration.ConclusionMicrosurgical resection of cervical intramedullary AVMs has obtained satisfactory clinical results. Preoperative magnetic resonance angiography, computed tomography angiography, and digital subtraction angiography are useful for evaluating the angioarchitecture, which is key to the success of surgery. Intraoperative indocyanine green fluorescence angiography is an important aid in the surgical treatment of spinal AVMs.Copyright © 2016 Elsevier Inc. All rights reserved.
