Summary
Microvascular repair of radial and ulnar arteries shows high early patency (86.1%) but a significant drop to 68.4% by 5.4 months. Arterial patency stabilizes after 90 days post-surgery.
Area of Science:
- Vascular Surgery
- Microsurgery
- Radiology
Background:
- Primary microvascular repair is crucial for limb salvage.
- Assessing long-term patency after arterial repair is essential for functional outcomes.
Purpose of the Study:
- To evaluate early and delayed patency rates after microvascular repair of radial and ulnar arteries.
- To identify factors influencing arterial patency post-repair.
Main Methods:
- Nuclear angiograms were performed within 1 week and at follow-up intervals (up to 2 years) on 36 patients.
- Survival analysis was used to assess patency trends over time.
- Patient demographics, injury characteristics, and surgical details were analyzed for correlation with patency.
Main Results:
- Early patency rate was 86.1% within the first week post-repair.
- Delayed patency decreased to 68.4% at an average follow-up of 5.4 months.
- Patency declined significantly in the first 90 days, then stabilized. No significant impact of age, sex, injury level, tourniquet time, or suture diameter was observed.
Conclusions:
- Microvascular arterial repair demonstrates good initial success, but sustained patency requires monitoring, especially within the first 90 days.
- Factors like partial vessel lacerations and non-smoking may positively influence long-term patency, though not statistically significant in this cohort.
