摘要
目的应用彩色多普勒血流成像技术(CDFI)对下肢皮瓣移植术前供区血管进行检测,掌握血管的来源走行、分布规律、体表的定位及血流动力学特点,为皮瓣设计提供依据。方法 2005年1月-2009年7月,采用CDFI技术对38例下肢皮瓣内深部动脉干及其肌皮穿支动脉血管的数目、内径、走行方向及分布范围等形态学表现进行检测和血流动力学定量分析。结果检出供区皮瓣内深部动脉干38条,肌皮穿支动脉72条。手术所见与此一致。38例皮瓣全部成活。结论 CDFI显像客观,简便易行,判断血管走行及功能可靠,能够准确测定下肢血管穿出部位和血管内径,对临床皮瓣设计,具有重要参考价值。
Objective The color Doppler ultrasound was used to assess the design of lower limbs flaps and to understand the vessel distribution of the skin flaps,so as to provide basis for design of skin flap.Methods Between January 2005 and July 2009,38 patients were enrolled in this study and the blood supply of their lower limbs prepared to design skin flap was analyzed by color Doppler flow imaging ( CDFI),and the vascular diameter and blood stream distribution were observed respectively.The quality of the blood vessel and its flowing dynamics were measured.Results Before operation,the blood vessel in donor areas had been completely found(100% ),and then the artery was verified by operation.For the skin flap in the donor areas,38 branches of arteries were deep,72 branches were shallow.The quality of the blood vessels by the color Doppler flow imaging was consistent with the results of operation.Conclusion The color Doppler flow imaging could show the quality of the blood vessels inside the donor area accurately.It is a premier choice for lower limb vascular examination for the design of skin flap.
