Abstract

Background: The number of anastomosed arteries and veins in replantation surgery of the hand is one of the most important factors in determining survival rate.
Objective: To evaluate the surgical and functional outcomes of replantation after injuries in the hand with different ratios of the repaired arteries and veins.
Patients and Methods: Twenty-one patients underwent replantation and revascularization procedures for hands and fingers amputation from April 2021 to the end of October 2021 in the Department of Plastic Surgery at Zagazig University Hospitals. According to arterial/venous (AV) ratio in optimizing replantation they were grouped into 3 groups, group I AV ration < 1 vein, group II: AV ration = 1 vein, group III: AV ration > 1 vein and they were followed up for more than six months
Results: There were a statistically significant increase in total active range of motion (TAM) degree among Group III compared to Group I and II. Regarding Chen criteria, there was a statistical significant increase in frequency of class I among Group III compared to Group I and Group II. There was a statistically significant –ve correlation between A/V ratio and TAM degree among the studied cases. Also, there was a statistical significant +ve correlation between A/V ratio and Chen criteria, two-point discrimination (2PD), and Q dash among the studied cases.
Conclusion: All hand surgeons should be able to perform digital replantation. A successful vessel anastomosis ensures the viability of the replanted portion of the body.
