Summary
The caliber-persistent labial artery is a benign vascular anomaly. High-resolution ultrasonography is preferred for diagnosis to avoid risky biopsies and potential bleeding.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
Background:
- The caliber-persistent labial artery is a rare vascular anomaly.
- It involves an arterial branch entering submucosal tissue without diameter reduction.
Observation:
- Most lesions are benign and asymptomatic.
- Treatment is typically reserved for complications or patient preference.
Findings:
- High-resolution and color Doppler ultrasonography are preferred noninvasive diagnostic tools.
- These methods allow direct visualization, precise measurement, and blood flow assessment.
Implications:
- Invasive procedures like excisional biopsy or surgical extirpation carry significant bleeding risks.
- Ultrasonography enables safe and accurate diagnosis, guiding conservative management.
