Abstract

Background: Fingertip replantation is technically challenging. Venous congestion is one of the most common causes of replantation failure. Therefore, various venous drainage procedures and salvage techniques have been used in venous congestion. Negative-pressure wound therapy has proven beneficial in limb injuries, yet limited studies of fingertip replantation exist. This study aims to analyze risk factors in fingertip replantation and to evaluate the feasibility and clinical benefits of negative-pressure wound therapy compared with other salvage techniques.

Methods: From January of 2015 to December of 2019, 27 patients (27 digits) who experienced fingertip amputation over Tamai zone I or II underwent replantation. Salvage negative-pressure wound therapy was applied for venous congestion postoperatively. Replantation data were collected for further analysis.

Results: The overall survival rate of digit replantation with salvage negative-pressure wound therapy was 92.6 percent (25 of 27). The blood transfusion rate was 11.1 percent (three of 27). The average hospitalization time was 8.04 ± 1.43 days and the median duration of negative-pressure wound therapy was 6 days (range, 4 to 8 days; interquartile range, 2 days). There is no significant difference between the survival and failure groups for all risk factors evaluated.

Conclusion: Negative-pressure wound therapy is a simple and effective salvage option to relieve venous congestion in fingertip replantation with a satisfactory survival rate, low blood transfusion rate, and short inpatient stay.

Clinical question/level of evidence: Therapeutic, IV.
