Abstract
Aim To report on patients who underwent surgical treatment of arteriovenous malformations (AVMs) at our institution.
Methods This retrospective single-center case series enrolled the patients who underwent surgical treatment of
pial AVM at the Department of Neurosurgery, University
Hospital Brno, between 2005 and 2019. The data are summarized as descriptive statistics presenting basic characteristics in all the patients and in sex or age subgroups.
Results Fifty patients were enrolled. The majority of AVMs
were of Spetzler-Martin grade II (n=27; 54%), localized supratentorialy (n=43; 86%), and half of AVMs were ruptured.
A total resection was performed in 48 patients (96%), and
a good overall outcome was achieved in 44 patients (88%).
Surgery-associated morbidity was 2%, and the mortality
rate was 0% due to meticulous selection of patients for
surgical treatment.
Conclusion Microsurgery is an appropriate method of
treatment for S-M grade I-III pial AVMs. Microsurgery may
be used to treat the majority of small-nidus AVMs with a
low mortality and morbidity, when precisely planned and
performed by an expert vascular team. The meticulous selection of patients for surgical treatment is crucial.
