METHODS Two groups were compared: 30 patients who underwent surgery and embolization versus 41 patients who underwent surgery only. Both groups were categorized by Spetzler-Martin grade and evaluated with the Glasgow Outcome Scale at various intervals. The long-term follow-up in months was, for surgery only, mean of 35 and range of 4 to 59, and for surgery and embolization, mean of 10 and range of 1 to 19). RESULTS The arteriovenous malformations in the surgery and embolization group had a larger average greatest diameter (4.2 +/- 1.5 cm versus 3.4 +/- 1.8 cm) and were of higher Spetzler-Martin grade (89\% versus 68\% grade III-V). No significant difference in the preoperative or immediate postoperative (less than 24 hours) Glasgow Outcome Scale was identified between the two groups. At I week after surgery, the surgery and embolization group displayed a significantly better outcome evaluation (70\% versus 41\% with Glasgow Outcome Scale score of 5). The long-term evaluation continued to favor the surgery and embolization patients (86\% versus 66\% with Glasgow Outcome Scale score of 5). CONCLUSION Preoperative N-butyl cyanoacrylate embolization improves postsurgical outcome.}, issn = {0195-6108}, URL = {https://www.ajnr.org/content/16/9/1801}, eprint = {https://www.ajnr.org/content/16/9/1801.full.pdf}, journal = {American Journal of Neuroradiology} }
