Cerebral CT angiography findings A single-center observational study.

Abstract

Introduction: This study aims to review the indications for CT angiography and the findings found at Alcívar Hospital, encouraging the study and understanding of the complex cerebral vascular system.

Methodology: A descriptive study was conducted, in which the findings were presented in tables and graphs. An atlas was created with images obtained from volumetric reconstructions.

Results: 190 CT angiography records were analyzed. The most common CT findings were anatomical variants (28.9%), aneurysms (4.7%), and arteriovenous malformations (3.2%). Vertebral artery hypoplasia (14.2%), posterior cerebral artery of fetal origin (10.5%), vertebral agenesis (3.2%), and agenesis of the A1 segment of the anterior cerebral artery (3.2%) were the most frequently found anatomical variants.

Conclusions: The results obtained correspond to those of similar studies. Although cerebral circulation is complex, it is possible to understand it and perform an efficient evaluation to safeguard patient integrity.
