Summary
A rare anatomical variation, a double vertebral artery originating from the subclavian artery, was identified in one cadaver. This finding has potential implications for clinical and surgical procedures.
Area of Science:
- Anatomical studies
- Vascular anatomy
- Human morphology
Background:
- The vertebral artery is a critical component of the cerebral circulation.
- Anatomical variations in the origin and course of the vertebral artery can impact surgical approaches and diagnostic interpretations.
Purpose of the Study:
- To document and describe a specific anatomical variation: a double vertebral artery originating from the subclavian artery.
- To highlight the potential clinical and surgical significance of this variation.
Main Methods:
- Gross anatomical dissection of 80 human cadavers.
- Detailed observation and description of vascular anomalies.
Main Results:
- A single instance of a double vertebral artery arising from the first part of the right subclavian artery was identified.
- The specific course and characteristics of this anomalous vessel were documented.
Conclusions:
- This case report details a rare anatomical variation of the vertebral artery.
- Understanding such variations is crucial for neurovascular surgery and the interpretation of imaging studies.
