【摘要】：目的研究CT血管造影(CTA)与彩色多普勒超声成像技术,对足趾供区血管情况进行术前评估的临床意义。材料和方法(1)术前采用彩色多普勒成像技术,检测25例手指缺损患者供区双足背动脉、第一跖背动脉的走行、起始内径大小情况及与皮肤的距离。(2)25例手指缺损患者术前行双足CT血管造影检查,应用计算机软件初步建立三维数字化模型,将供区血管走行、毗邻精准定位,标测、量化血管起始内径。结果25例患者足部第一跖背动脉均能在彩色多普勒和CTA检测中显现。术前两种检测方法所得血管走向、充盈情况与术中一致。第一跖背动脉起始内径平均值差异有统计学意义(P0.05),而皮下距离所得平均值差异无统计学意义(P0.05)。25例再造指均顺利成活。结论CTA与彩色多普勒成像技术相结合用于足趾移植再造拇指术前检查,能准确反映供区血管的解剖学结构特点并提供个体化的、清晰的足部血供图像,对拇手指再造术术前评估足部供区血供具有重要的临床价值。
[Abstract]:Objective to study the clinical significance of CT angiography (CTAA) and color Doppler ultrasound (CDFI) in preoperative evaluation of vascular status in the toe donor area. Materials and methods before operation, color Doppler imaging technique was used to detect the movement of the first dorsal metatarsal artery and the bilateral dorsal foot artery in the donor area of 25 patients with finger defect. The size of the initial inner diameter and the distance to the skin. 25 patients with finger defect were examined by bipedal CT angiography before operation. The three-dimensional digital model was established by computer software. The donor vessels were located and mapped accurately. The initial diameter of blood vessels was quantified. Results the first dorsal metatarsal artery could be detected by color Doppler and CTA in 25 patients. The blood vessel orientation obtained by the two methods before operation was consistent with that of intraoperative filling. There was significant difference in the initial diameter of the first dorsal metatarsal artery (P0.05), but there was no significant difference in the subcutaneous distance between the two groups. Conclusion CTA combined with color Doppler imaging can accurately reflect the anatomical features of donor vessels and provide individualized and clear images of blood supply to the foot for thumb reconstruction after toe transplantation. It is of important clinical value to evaluate the blood supply of foot region before thumb and finger reconstruction.
