Abstract:
Objective:To compare the clinical value of CTA and CDU in perforator flap of peroneal artery.Methods:From February 2013 to October 2016, 47 patients who suffered with soft tissue defects and were hospitalised in the Department of Orthopaedics, the 920th Hospital of Joint Logistic Support Force of Chinese PLA were retrospectively reviewed and evaluated. All the defects were reconstructed by the perforator flap of peroneal artery. All patients received preoperative CTA and CDU scans before surgery. Appropriate perforator vessels were selected and the locating points in body surface and external diameters of the perforator vessels were recorded and compared with intraoperative findings. SPSS 22.0 statistical software was used for data analysis. P<0.05 was considered statistically significant. Results:The intraoperative coincidence rate of the proposed perforator vessels was 97.87% for CDU and 95.74% for CTA, with no significant difference between the 2 groups( P>0.05). It was found that the preoperative CTA and CDU measurements were consistent with the actual intraoperative measurements, and there was no significant difference between the 2 groups( P>0.05). For CTA combined with CDU, an intraoperative coincidence rate was 100% in the location of peroneal perforating vessels. All flaps were followed-up for 1 to 18(mean 13.5) months. All the flaps survived well with good texture and appearance without complication. Conclusion:CDU and CTA are reliable and useful in preoperative vascular evaluation of peroneal perforator flap, and both can be used in a complementary or combined manner.
