ABSTRACT
Objectives:
Brain arteriovenous malformations (AVMs) represent high-flow vascular lesions made up of a complex network of feeding arteries and draining veins interposed by a nidus and without a capillary bed. The management of the AVMs represents a challenge, and the optimal treatment should be considered based on the particularities of each AVM. This paper aims to provide outcome data for the cohort of patients with AVMs that underwent surgical treatment.Methods:
A retrospective review of patients who presented with AVMs between 2001 and 2019 was conducted. Patients were included if they underwent surgery, preoperative and postoperative angiographic studies were available.Results:
91 patients were included. The SM grade was 1 in 16 cases (17,6%), 2 in 27 patients (29.7%), 3 in 29 patients (31,9%), 4 in 12 cases (13.2%) and grade 5 in 7 cases (7.7%). In 58 (63.7%) cases the AVMs were ruptured. Complete microsurgical resection was achieved in 82 cases (90.1%). Unruptured AVM (87.9% vs. 63.8% for ruptured AVMs; p = 0.015), low-grade AVM (86% vs. 60.4% for grade III-V AVMs; p = 0.006) and cortical location (79.5% vs. 30.8% for deep AVM; p < 0.0001) were the factors associated with a good outcome on mRS scale.Conclusions:
Microsurgical resection is the curative treatment for AVMs and offers a good functional outcome if selection criteria are met.Palabras clave
