Reverse Distal Transverse Palmar Arch in Distal Digital Replantation

Area of Science:

• Microsurgery
• Vascular Surgery
• Reconstructive Surgery

Background:

• Distal finger replantation is a complex microsurgical procedure.
• Small vessel size and length limitations often necessitate venous grafts.
• A novel technique is presented to overcome these limitations.

Purpose of the Study:

• To describe and evaluate a new technique for digital replantation anastomosis.
• To eliminate the need for interpositional venous grafts in fingertip replantation.
• To assess the efficacy and outcomes of the reverse distal transverse palmar arch technique.

Main Methods:

• The reverse distal transverse palmar arch technique was applied in 11 distal digital replantations.
• Arterial anastomosis was performed using this technique in 10 cases.
• A retrospective review analyzed technical aspects and clinical outcomes.

Main Results:

• An overall success rate of 91% was achieved, with 10 out of 11 replanted digits surviving.
• Replanted digits showed near-normal range of motion, good aesthetics, and protective sensation.
• Patients reported satisfaction and returned to work, with an average hospital stay of 5 days.

Conclusions:

• The reverse distal transverse palmar arch technique is a reliable method for digital replantation.
• This technique allows for tension-free arterial repair without requiring vein grafts.
• It offers a valuable alternative for cases needing increased vessel length in fingertip replantation.
