Clinical Report: Reconstruction of Lower Extremity Vascular Injuries Utilizing Autologous Vein Grafts with a Parallel Connection Technique

Overview

This study evaluates the parallel connection method for reconstructing lower extremity vascular injuries using autologous vein grafts. Results indicate lower thrombosis and amputation rates compared to direct autogenous vein grafting, although with longer operative times.

Background

Lower extremity vascular injuries are critical conditions that can lead to severe complications, including limb amputation. Autologous venous grafting is the standard approach for vascular reconstruction, yet challenges arise when the caliber of the donor vein does not match the recipient vessel. The parallel connection technique aims to address these challenges and improve surgical outcomes.

Data Highlights

Key Findings

• The parallel connection method resulted in a thrombosis rate of 5.88% compared to 53.85% for direct autogenous vein grafting (P < 0.05).
• Amputation rates were 0% in the parallel connection group versus 38.46% in the direct graft group (P < 0.05).
• For venous reconstruction, the thrombosis rate was 7.69% in the parallel connection group compared to 57.14% in the direct group (P < 0.05).
• The procedure time was significantly longer for the parallel connection method (P < 0.05).
• No pseudoaneurysm, stenosis, or thromboembolism was observed in the target vessels during follow-up (23–60 months).

Clinical Implications

Clinicians should consider the longer operative time associated with the parallel connection method.

Conclusion

The parallel connection method demonstrates differences in outcomes in vascular injury reconstruction compared to direct autogenous vein grafting.
