Reconstruct the distal blood supply of multiple segments of severed finger body by arterial bridge transfer / 中华显微外科杂志

ABSTRACT

Objective:To investigate the surgical method and therapeutic effect of reconstruction of distal blood supply of multiple segments of severed finger body by ortho phalanx artery bridge transfer.Methods:Between November, 2005 and February, 2019, 7 finger body was replanted in 7 cases with 3 segments. Due to the short middle finger body and severe bruising, the power could not pass through the middle section after the proximal finger artery anastomosis. For the long section of blood supply, in order to prevent the skin and blood vessels from separating too much and causing the middle internal artery to separate from the phalanx, after anastomosis of the middle artery, the blood supply was provided by anastomosis with the distal phalanx artery by means of the adjacent phalanx artery bridge. Four cases with vascular pedicle grafts. The skin was sewn into tube in 3 cases, and separate fingers between 3.5 and 6.0 months after operation. Four cases of posterior artery recalcitration and 3 cases of direct adjacent artery transposition. The appearance, sensation and total motion of finger joints were observed and the satisfaction of patients was investigated to evaluate the therapeutic effect.Results:Seven patients with replantation finger were all alive after operation, and the follow-up time was 5 to 40 months respectively. The total range of motion of flexion and extension of finger joints was 100°-170°, and the TPD of finger pulp was 7-12 mm, with an average of 9.6 mm. According to Michigan's functional questionnaire, 7 patients were satisfied with the overall appearance and function of their opponents. According to the evaluation standard of the replantation function of the broken finger of the Chinese Medical Association, 3 cases were excellent and 4 cases were good.Conclusion:It is a simple and effective way to reconstruct the blood supply of multi-segment severed fingers by means of adjacent finger artery bridge transfer.
