Spinal arteriovenous lesions (SAVLs), arteriovenous fistulas (AVFs) and arteriovenous malformations (AVMs), are rare and can devastatingly impair spinal cord function. This study aimed to evaluate clinical outcomes after microsurgical treatment with the aid of intraoperative indocyanine green video-angiography (ICG-VA) in a large series of patients with SAVLs. We retrospectively reviewed the cases of 95 consecutive patients with 105 SAVLs (77 spinal AVFs, 28 spinal AVMs) who had been treated surgically during 2010-2016 in two hospitals by the same experienced surgeon. All patients had undergone magnetic resonance imaging and digital subtraction angiography preoperatively and were assessed using the modified Aminoff and Logue Scale (mALS). All lesions were resected or occluded using ICG-VA. No ICG-VA-related complications occurred. Compared with AVF, patients with AVM tended to be younger (p < 0.001) and were at higher risk of an associated aneurysm (p = 0.021), hemorrhage (p < 0.001), pain (p < 0.001) and abrupt onset (p < 0.001). SAVLs were most common in the lower thoracic region (45.71%), and their most common clinical presentation was paresthesia (89.52%). At a mean follow-up of 33.3 months, mALS indicated significant improvement in patients with spinal AVFs (p < 0.001) and AVMs (p = 0.002) compared with their status preoperatively. An improved, stable clinical status was noted at the last follow-up in 93.51% of those with AVFs and 89.28% of those with AVMs. Thus, microsurgical treatment of SAVLs produced a lasting positive clinical outcome in a large cohort of consecutive patients. ICG-VA proved to be an efficient intraoperative tool during resection of these lesions, especially in patients with an AVF. (C) 2017 Published by Elsevier Ltd.
