Influence of the angioarchitectonics of supratentorial brain arteriovenous malformations on cognitive functions and quality of life
Abstract
AIM OF THE STUDY is to assess the influence of unruptured brain AVM’s angioarchitecture on cognitive functions and quality of life.
MATERIALS AND METHODS. Cognitive functions and quality of life in 40 patients with unruptured supratentorial AVMs and 50 normal controls were assessed. Results of neuropsychological testing were correlated with anatomy of AVMs.
RESULTS. Cognitive impairment was found more than in 30% of brain AVM cases. Predictors of cognitive impairment are follow: diameter of AVM > 3 cm, participation of 2 and more sources of blood supply, deep drainage and venous outflow disruption. Assessment by SF-36 questionnaire found increase of anxiety and decrease of quality of life in patients with AVM. Venous obstructions and involvement of ECA branches are negative prognostic factors for cognitive impairment.
CONCLUSION. Medium/large size AVM and existence of deep drainage or venous obstacles are predictors for cognitive impairment in patients with unruptured AVM’s. Presence of AVM decreases quality of life by restriction of activity and high level of anxiety.
