Hypothesis
Does the persistent median artery contribute to the development of carpal tunnel syndrome?
Conclusion
The persistent median artery should be considered a differential diagnosis for carpal tunnel syndrome, and ultrasonography is a reliable method to predict carpal tunnel anatomy.
Supporting Evidence
- Median artery thrombosis showed statistical differences based on sex, electroneuromyography findings, profession, and total duration of symptoms.
- Ultrasonography is a reliable method to predict carpal tunnel anatomy.
- Late onset of symptoms could influence artery thrombosis and worsen symptoms.
Takeaway
Some people have a special artery in their wrist that can cause problems with their hand. Doctors can use special pictures to see if this artery is causing trouble.
Methodology
A retrospective study reviewing medical records of patients with carpal tunnel syndrome associated with persistent median artery who underwent decompression surgery.
Potential Biases
Potential bias due to the retrospective nature of the study and exclusion of certain patient groups.
Limitations
The study had a small sample size and did not include patients who underwent surgery at the same time since the onset of symptoms.
Participant Demographics
Mean age was 41 years, with 17 females and 8 males; 24 patients were right-handed.
