摘要
目的比较灰阶血流成像(B-flow)与CDFI在穿支皮瓣术前定位中的价值。方法选取在我院接受皮瓣移植术的患者30例,术前分别应用CDFI和B-flow检测皮瓣供区的穿支血管,定位并标记最优穿支的穿出点;术中分别测量CDFI、B-flow定位穿刺点到术中确定穿出点的距离(AC值、BC值),比较二者检查耗时及显示穿支血管数目,以及AC值与BC值的差异。结果B-flow的检查耗时少于CDFI检测耗时[(6.700±1.207)min vs.(10.333±1.398)min],检测穿支血管数量多于CDFI所测[(3,1)vs.(2,0)],BC值小于AC值[(4.233±1.194)mm vs.(5.667±1.917)mm],差异均有统计学意义(均P<0.05)。结论B-flow对穿支血管的检测优于CDFI,且其定位更加准确。
Objective To compare the value of B-mode blood flow imaging(B-flow)and CDFI in preoperative localization of perforator flaps.Methods A total of 30 patients who underwent flap transplantation in our hospital was enrolled.CDFI and B-flow were used to detect the number of perforator vessels in the donor area of the flap before surgery,and the outlet point of the optimal perforator was located and marked.The distance from the puncture point to the outlet point was recorded as AC value of CDFI and BC value of B-flow,respectively during surgery.The examination time and the number of perforators of CDFI and B-flow and the difference between AC value and BC value were compared.Results The examination time of B-flow was less than that of CDFI[(6.700±1.207)min vs.(10.333±1.398)min].The number of perforators detected by B-flow was more than that of CDFI[(3,1)vs.(2,0)].And the BC value was less than the AC value[(4.233±1.194)mm vs.(5.667±1.917)mm].All the differences were statistically significant(all P<0.05).Conclusion B-flow is more effective than CDFI in detecting perforator vessels,and the localization of perforator vessels is more accurate.
