【摘要】：目的探讨动脉插管造影CTA活体显影股前外侧穿支皮瓣穿支血管的可行性。方法选取拟定切取股前外侧穿支皮瓣移植患者15例。实验组运用选择性动脉插管技术将导管置入旋股外侧动脉开口处,证实导管达到预定位置并固定可靠后将患者转移至CT室。经导管注入造影剂20 ml,同时手动触发CT扫描。选取普通CTA作为对照组。将两组获得的二维图像以CT-DICOM输入到Mimics17.0软件,收集两组旋股外侧动脉主干及其分支的解剖学参数。采用SPSS22.0统计软件对数据进行统计处理,P值≤0.05认为差异有统计学意义。结果本组15例患者中,1例患者导管脱落至股深动脉,予以排除。其余14例患者中,旋股外侧动脉起源于股动脉3例(占21.43%),起源于股深动脉11例(占78.57%)。实验组旋股外侧动脉及其分支内径大于对照组。实验组升支、横支及降支长度均大于对照组,升支、横支及降支的末端最小内径均小于对照组。实验组显影穿支数目多于对照组。结论动脉插管造影CTA可清楚的显示旋股外侧动脉分支及其穿支,效果优于普通CTA。
[Abstract]:Objective to investigate the feasibility of CTA angiography in the perforating branch of anterolateral femoral perforator flap. Methods Fifteen patients with anterolateral femoral perforator flap were selected. In the experimental group, the catheter was placed into the opening of lateral circumflex femoral artery by selective arterial catheterization, and the catheter was confirmed to reach the predetermined position and fixed reliably, then the patient was transferred to the CT room. Contrast agent 20 ml was injected through catheter and CT scan was triggered manually. General CTA was selected as control group. The two groups of 2D images were inputted into Mimics 17.0 software by CT-DICOM to collect the anatomical parameters of the lateral femoral circumflex artery trunk and its branches. SPSS 22.0 statistical software was used to process the data (P 鈮，
