Abstract:
Objective:To explore the effect of dorsal branch flap of digital artery for repairing local soft tissue defect of fingers on hemodynamics and cicatrix of affected finger.Methods:One hundred patients with local soft tissue defect of fingers who were operated in the Central Hospital of Enshi Tujia and Miao Autonomous Prefecture from June 2017 to June 2020 were selected and 46 patients were treated with bridging repair of dorsal branch flap of digital artery (digital artery group) and 54 patients were treated with superficial branch of radial artery wrist crease flap repairing surgery (radial artery group). The superior rate of surgery, surgical related indexes and the total incidence of postoperative complications were compared between the two groups. The changes of hemodynamics index, postoperative flap repair scores visual analog scale (VAS) scores and Vancouver Scar Scale Score (VSS) scores were compared between the two groups.Results:The superior rate of surgery between the two groups had no significant difference ( P>0.05). The two-point discrimination in the digital artery group was less than that in the radial artery group: (5.09 ± 1.27) mm vs. (6.71 ± 1.46) mm; and the healing time and hospitalization time in the digital artery group were shorter than those in the radial artery group: (17.69 ± 2.42) d vs. (19.83 ± 2.11) d, (10.18 ± 1.46) d vs. (11.97 ± 1.52) d, there were statistical differences ( P<0.05). The operation time, first stage healing rate, tactile, cold, heat and pain recovery rate between the two groups had no significant differences ( P>0.05). After operation for 3 d, the blood flow velocity (BFV), relative value of blood perfusion volume (BPR) in the digital artery group were higher than those in the radial artery group: (36.89 ± 2.10) cm/s vs. (35.02 ± 2.07) cm/s, (65.28 ± 4.61)% vs. (62.34 ± 4.58)%, there were statistical differences ( P<0.05). After operation for 1 week, the flap repair scores in the digital artery group was higher than that in the radial artery group: (12.34 ± 1.61) scores vs. (11.01 ± 1.58) scores; and the VAS and VSS scores in the digital artery group were lower than those in the radial artery group: (2.68 ± 0.34) scores vs. (2.89 ± 0.38) scores, (4.05 ± 0.65) scores vs. (4.52 ± 0.62) scores, there were statistical differences ( P<0.05). There was no significant difference in the incidence of postoperative complications between the two groups ( P>0.05). Conclusions:Dorsal branch flap of digital artery for repairing local soft tissue defect of fingers can contribute to the hemodynamic recovery of the affected finger, relieve the degree of postoperative pain, promote postoperative recovery, and reduce the severity of cicatrix.
