Perfil de anormalidades cerebrovasculares detectadas no Hospital Geral de Palmas - TO

Abstract

Cerebrovascular diseases are significant causes of morbidity and mortality. Understanding their population profile allows health services to take precautions regarding prevention, diagnosis and management. The aim of this study is to identify the profile of encephalic vascular anomalies in patients at a reference hospital in the state of Tocantins (HGP). 140 arteriographic reports performed at HGP in 2019 were analyzed, identifying the types, respective frequencies and morphological characteristics of each anomaly. Data were analyzed by Binomial and Chi-Square test for expected distribution analysis (α=5%). A total of 194 cerebrovascular diseases were found: aneurysms (70.7%; χ2=410.723; GL=5; p<0.001), vasospasms (14.9%), stenosis (7.5%) and arteriovenous malformations (4.8%) , which predominated in the Willis Polygon region (59.9%; B=75,000; SE=6.837; p=0.008). The most frequent aneurysms were observed in the vessels: carotid (39.4%), communicating (30.3%), and cerebral (20.5%). The distribution and predominance of aneurysms analyzed were topographically compatible with the consensual literature data, as well as its greater predominance in females. The main cerebrovascular findings were aneurysms, vasospasms and stenosis, predominantly affecting the Polygon of Willis and adjacent regions, especially in the carotid and cerebral arteries.
