| 目的 比较B-flow和彩色多普勒血流显像(CDFI)在穿支皮瓣术前定位中的价值。方法 选取30例于本院接受皮瓣移植术的患者,术前分别用CDFI和B-flow检测皮瓣供区的穿支血管；比较两者检查耗时及显示穿支血管数目的优劣。并根据穿支血管的内径、走行、峰值流速、RI等指标选择最优穿支血管,术前分别用CDFI和B-flow定位并标记最优穿支的穿出点,术中分别测量其到术中确定穿出点的距离,分别计为AC值和BC值,比较AC值与BC值的差异。结果 ①B-flow检查耗时小于CDFI耗时(t=12.721,P<0.05)。②B-flow检测穿支血管优于CDFI(Z =-3.528,P<0.05)。③BC值小于AC值(t=3.328,P＜0.05)。 |

| Abstract: |
| Objective To compare the value of B-flow and color dopplor flow image(CDFI) in preoperative localization of perforator flap. Methods Of 30 patients who underwent flap transplantation in our hospital, CDFI and B-flow were used to detect the number of perforator vessels in the donor site of the flap before surgery. The times taken using CDFI and B-flow to detect perforating vessels were recorded before surgery, and the differences between the two modes were compared. The differences between CDFI and B-flow used to detect the number of perforator vessels in the flap donor area were compared; According to the inner diameter, path, peak systolic velocity (PSV), resistance index (RI) and other indicators of the perforator vessels, the optimal perforator vessels were selected. CDFI and B-flow were used to locate and mark the optimal perforator vessel point for the perforator flap before surgery. During the operation, the distance to the actual puncture point was measured separately and counted as the AC value and BC value to compare the difference between AC and BC. Results ① B-flow takes less time than CDFI (t=12.721, P<0.05).②B-flow was better than CDFI in detecting perforator vessels (Z =-3.528,P<0.05).③The BC value was lower than the AC value (t=3.328, P <0.05). |
