Ruptured cerebral arteriovenous malformations: Outcomes analysis after microsurgery
Abstract
Our study aimed to evaluate the functional outcome and the risk of postoperative remnant in patients with rAVM after microsurgical treatment. This is a retrospective of 139 consecutive patients operated for a rAVM between 2002 and 2012 in our institution. The age at diagnosis and the WFNS score were recorded for each patient before treatment. All patients were re-evaluated 3 months after treatment using mRS scale. Conventional angiography was performed in the first 2 postoperative weeks and then a year later to detect any remnant or recurrence. The mean age at diagnosis was 30.8 years (range 4-69 SD: ±5) and 44 patients had an age at diagnosis <18yo. The mRS score 3 months after treatment was ≤2 in 104 patients (83%). Predictive factors of good functional outcome were age at diagnosis <25yo, initial WFNS score≤2, SPM grade≤2 and absence of acute hydrocephalus (p<0.05). Complete obliteration was obtained in 123 patients (89.5%) after the first microsurgical treatment. Early postoperative conventional angiography revealed a rAVM remnant in 16 patients (10.5%). Late conventional angiography showed a recurrence in 6 patients (4.5%). All of them were <18yo. Predictive factors of postoperative rAVM remnant were an initial WFNS score>...Continue Reading
