应用彩色多普勒影像技术设计轴型皮瓣

THE DESIGN OF AXIAL PATTERN FLAP WITH COLOR DOPPLER FLOW IMAGING TECHNIQUE

目的 利用彩色多普勒影像技术设计轴型皮瓣 ,克服既往设计时血管不能直观显像的缺陷。方法 选用不同部位的轴型皮瓣 10例 ,术前在传统设计方法的基础上 ,采用高分辨彩色多普勒检测轴型皮瓣供血动脉的起止点、长度等 ,根据检测结果再次设计皮瓣并转移覆盖创面。结果 除 1例未能完成手术外 ,其余 9例成活良好。结论 该方法具有能直观和准确诊断轴型皮瓣血管的起止点、走向等优点 。

Objective To study the effect of color doppler flow imaging(CDFI) technique in the design of axial pattern flap. Methods From April 1996 to June 1999, 10 patients with residul wound were adopted in this study. Among them, there were seven males and three females, the area of wounds ranged from 6 cm×8 cm to 15 cm ×20 cm. Before operation, the axial pattern flaps were designed by traditional method, then CDFI technique with high frequency(5.0 ～7.5 MHz) was used for examining the major supply artery of the flap. At last, the modified flaps were transferred to cover the wounds. Results All the patients except one case completed the operation successfully. The cosmetic and function of the flaps were excellent. Conclusion CDFI is a simple, direct and accurate method for detecting the supply artery of axial pattern flap. This technique should be popularized to avoid the blindness of flap design.
