CTA联合CDFI在股前外穿支皮瓣修复软组织损伤中的应用

Application of CTA Combined with CDFI in the Repair of Soft Tissue Injury with Anterior Thigh Perforator Flap

探讨CT血管成像(CTA)联合彩色多普勒血流成像(CDFI)在股前外穿支皮瓣修复上下肢软组织损伤中的应用。选取拟进行股前外穿支皮瓣(ALTPF)移植的患者58例,将其分为CTA组和CDFI组,每组各29例。术前,分别应用CTA、CDFI进行皮瓣设计和骨前外穿支定位,观察受试者修复情况。结果发现,CTA组和CDFI组皮瓣皮温均有1例较高,其他温度均处于正常范围,无血管危险出现,全部存活;CTA组与CDFI组旋股外侧动脉降支的平均流速和最大流速均无显著差异(P>0.05)。CDFI与CTA均可应用于股前外穿支皮瓣,满足受损上下肢软组织重建手术。

This article explored the application of CT angiography(CTA) imaging combined with color Doppler flow imaging(CDFI) in the repair of soft tissue injuries of the upper and lower extremities with external perforator flaps. Fifty-eight patients planned to undergo anterolateral thigh perforator flap(ALTPF) transplantation were selected in this hospital and divided into CTA group and CDFI group, each with 29 cases. CTA and CDFI were used for skin grafting before surgery. The flap design and the positioning of the anterior and outer perforating branches of the bone, observe the repair of the subjects. The results showed that the skin temperature of the flaps in the CTA group and the CDFI group was higher in 1 case, and the other temperatures were in the normal range. There was no risk of blood vessels and all survived;the average flow velocity and the maximum value of the descending branch of the lateral femoral circumflex artery in the CTA group and the CDFI group. There was no significant difference in flow rate(P>0.05). Both CDFI and CTA can be applied to the anterior thigh and outer perforator flap to meet the needs of reconstructing soft tissues in the upper and lower limbs.
