Abstract

Anatomical variations of aortic arch branching patterns: an evaluation using digital subtraction angiography

Abstract

Abstract Background: Anatomical variations in the aortic arch branching pattern are crucial for planning surgical and endovascular procedures. These variations, often detected incidentally during radiological studies, can influence the approach and success rate of interventions. Objective: To retrospectively analyze the variations in the aortic arch branching patterns using digital subtraction angiography (DSA) and compare the findings with existing literature. Methods: A retrospective analysis was conducted on 221 patients who underwent arcus aortography with DSA for neurovascular pathologies at the University of Ümraniye Education and Research Hospital from January 2020 to November 2022. Patients with previous thoracic-vascular surgery were excluded. The aortic arch findings were categorized according to established classifications. Results: Six distinct aortic arch branching patterns were identified among the 221 patients. The most common type was the normal or classical form (Type 1) found in 78.3% of the patients. Type 2, where the left common carotid artery originates from the brachiocephalic trunk, was observed in 19.9% of the cases. Type 3, characterized by the left vertebral artery originating directly from the aortic arch, was seen in 0.9% of the patients. Other types, including right aortic arch with aberrant right subclavian artery, were less common. Type 3 variations were more prevalent among females, while other variations showed no significant gender difference. Conclusion: Variations in the aortic arch branching patterns are common and generally asymptomatic but have significant implications for surgical and interventional procedures. Recognizing these variations is essential for improving procedural success rates and reducing complications in neurovascular interventions.
