【摘要】 目的 應用彩色多普勒血流成像技術（CDFI）對下肢皮瓣移植術前供區血管進行檢測，掌握血管的來源走行、分布規律、體表的定位及血流動力學特點，為皮瓣設計提供依據。 方法 2005年1月-2009年7月，采用CDFI技術對38例下肢皮瓣內深部動脈干及其肌皮穿支動脈血管的數目、內徑、走行方向及分布范圍等形態學表現進行檢測和血流動力學定量分析。 結果 檢出供區皮瓣內深部動脈干38條，肌皮穿支動脈72條。手術所見與此一致。38例皮瓣全部成活。 結論 CDFI顯像客觀，簡便易行，判斷血管走行及功能可靠，能夠準確測定下肢血管穿出部位和血管內徑，對臨床皮瓣設計，具有重要參考價值。【Abstract】 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.
