Objective:To study the clinical effects of CTA and Doppler ultrasound positioning method for repairing perforating artery leg soft tissue defect in the anterolateral thigh flap. Methods:In our hospital from July 2014 to July 2016, 180 cases of leg soft tissue defect were randomly divided into non traumatic vascular imaging group(Computed Tomography, angiography, CTA), Doppler ultrasound blood flow detector group and combination group(CTA+intraoperative Doppler ultrasound blood flow detector) group, 60 cases in each, were repaired by the anterolateral thigh flap, the effect was compared between the three groups. Results:The coincidence rate of the diagnosis of perforating arteries in the combined group was 100%(60/60), which was higher than that of the Doppler ultrasonic blood flow detector group and the CTA group 78.33%(47/60), 76.67%(46/60), and the difference between the two groups was statistically significant (P<0.05).The combined group complication rate was 3.33% (2/60), significantly higher than that of Doppler ultrasound blood flow detector group and CTA group 15% (9/60), 13.33% (8/60), there was a statistical significance between the groups (P<0.05).The combined group had a satisfaction and Barthel score of 96.7±1.8, 68.7±2.1, which was significantly higher than that of Doppler ultrasound blood flow detector group and CTA group, there was a statistical significance between the groups (P<0.05). Conclusion:The coincidence rate of perforating artery with Doppler ultrasound blood flow detector in CTA and operation is the highest, and the anterolateral thigh perforator flap is the best for repairing small leg soft tissue defect. It can be used as a clinical optimized scheme. |
