Summary
An unusual origin of the ulnar artery from the axillary artery was found during an upper extremity angiogram. This anatomical variation highlights the importance of understanding arterial patterns to prevent complications during medical procedures.
Area of Science:
- Anatomy
- Vascular Surgery
- Radiology
Background:
- Anatomical variations in the upper extremity vasculature can impact surgical and diagnostic procedures.
- The ulnar artery typically arises from the brachial artery, a continuation of the axillary artery.
Purpose of the Study:
- To report a rare case of axillary origin of the ulnar artery.
- To emphasize the clinical significance of recognizing vascular anomalies in the upper limb.
Main Methods:
- Angiographic examination of the upper extremity vasculature.
- Detailed anatomical description of the observed arterial variant.
Main Results:
- A unique origin of the ulnar artery directly from the axillary artery was identified.
- The anomalous origin occurred at the level of the anterior and posterior circumflex humeral arteries.
- No other vascular anomalies were noted in the examined extremity.
Conclusions:
- Awareness of the axillary origin of the ulnar artery is crucial for clinicians.
- Recognition of such anatomical variations can mitigate risks during invasive procedures of the upper limb.
- This case underscores the importance of thorough pre-procedural vascular assessment.
