We appreciate the comments by Bervini and Morgan regarding our publication “Microsurgical resection of Spetzler–Martin grades 1 and 2 unruptured brain arteriovenous malformations results in lower long-term morbidity and loss of quality-adjusted life-years (QALY) than conservative management- Results of a single group series”. They challenge our somewhat-simplified conclusion that at present a benefit of microsurgical treatment of Spetzler–Martin (SM) grade 1 and 2 arteriovenous malformation (AVMs) can be accepted with certainty while this is not the case for SM grades 3 and 4. They argue that, despite its high morbidity, microsurgical treatment mortality for unruptured SM grade 3 AVM is likely lower than the long-term mortality resulting from the natural history. …
