胫后动脉穿支皮瓣与吻合皮下静脉的带蒂皮瓣对四肢皮肤 及软组织缺损的应用效果对比.

Objective: To compare the application effect of the posterior tibial artery perforator flap and the pedicled skin flap anastomosing subcutaneous veins on skin and soft tissue defects in the limbs. Methods: 68 patients with limb skin and soft tissue defects admitted to our hospital from March 2017 to March 2022 were selected as the study subjects, with 34 cases in each group. All patients underwent flap repair surgery, while the matched group received treatment with the posterior tibial artery perforator flap, while the observation group received treatment with a pedicle skin flap anastomosing the subcutaneous vein. Compare the clinical efficacy, intraoperative bleeding volume, surgical time, hospital stay, wound healing time, postoperative pain level, and sensory function recovery between the two groups of patients. Finally, conduct a one-year follow-up of the two groups of patients to compare their incidence of complications and secondary repair within one year. Results: The total response rate was higher in the observation group than in the matched group (P<0.05); There was no difference in intraoperative bleeding volume, surgical time, and postoperative VAS score between the two groups of patients. The observation group had lower hospital stay and wound healing time than the matched group(P<0.05); There was no difference in the number of patients with postoperative sensory function recovery at S3, S2, S1, and SO levels between the two groups (P>0.05). The number of patients with postoperative sensory function recovery at S4 level in the observation group was higher than that in the matched group (P<0.05); The rate of postoperative complications and the rate of postoperative secondary repair in the observation group were significantly lower than that in the matched group (P<0.05). Conclusion: Compared with the repair of skin and soft tissue defects in the limbs using the posterior tibial artery perforator flap, the repair of pedicle skin flap with subcutaneous vein anastomosis can further improve the treatment effect, shorten the hospitalization time of patients, promote wound healing, improve postoperative sensory function recovery level, reduce the incidence of long-term complications and secondary repair rate, and is worthy of clinical application and promotion [ABSTRACT FROM AUTHOR]
