Clinical effect analysis of palmar venous anastomosis in fingertip replantation

Objective To investigate the feasibility and clinical effect of palmar venous anastomosis in fingertip replantation. Methods From October, 2008 to May, 2017, the clinical data of 15 patients with 24 finger replantation were retrospectively analyzed by outpatient, telephone and WeChat followed-up. One artery was anastomosed for revascularization with or without nerve repair, and 1 palmar venous anastomosis was performed to reestablish the outflow system. The finger nerve was sutured randomly according to the injury. Results The patients were followed-up for 18-65 (mean, 39.9) months. Except for 1 replantation finger with rotation avulsed injury failed, the remaining 14 cases with 23 fingers survived completely. Excellent restoration of finger motion was observed during the follow-up. The mean regained static 2-point discrimination sensation was 3.6 (2.8-4.0) mm. All patients were satisfied with the treatment effect. Conclusion Successful palmar venous anastomosis can improve the survival rate of replanted fingertips, simplify postoperative care, reduce postoperative complications, and improve the treatment effect.
