【摘要】：目的采用彩色多普勒超声检查观察健康志愿者腹壁下动脉的血管走行及血流动力学参数,探讨彩色多普勒超声检查在腹壁下动脉穿支皮瓣移植术术前皮瓣定位及设计中的应用价值。方法健康志愿者150例,根据年龄分为20~29岁组、30~39岁组、40~49岁组、50~59岁组、60~69岁组,每组各30例(60条血管)。采用彩色多普勒超声检查观察腹壁下动脉血管走行和发出穿支情况,测量主干长度(L)、起始处管径D1、脐水平处管径D2及收缩期峰值流速(PSV)、舒张期流速(EDV)、搏动指数(PI)、阻力指数(RI)。结果 150例受检者的300条腹壁下动脉均在彩色多普勒超声图像中清晰显示。283条腹壁下动脉起自髂外动脉,17条发自股动脉。腹壁下动脉发出后自腹股沟韧带中点处向内上行,在腹直肌外缘后方穿腹横筋膜耻骨联合上方入腹直肌鞘内,于腹直肌与腹直肌后鞘间上升至脐上方,在脐上一个腱划水平与腹壁上动脉形成终末吻合支。腹壁下动脉走行过程中测及穿支(3.85±0.87)支,设定血管口径≥0.5 mm为可用穿支,每位受检者每侧可用穿支为(1.96±0.91)支。各年龄组间腹壁下动脉L、D1、D2、PSV、PI相比,P均0.05。结论彩色多普勒超声检查可获得正常人腹壁下动脉及其穿支血管走行情况和血流动力学参数,为腹壁下动脉穿支皮瓣移植术术前皮瓣定位及设计提供参考。
[Abstract]:Objective to observe the blood flow and hemodynamic parameters of the inferior abdominal artery in healthy volunteers by color Doppler ultrasound (CDFI). To evaluate the value of color Doppler ultrasonography in the localization and design of the skin flap before transplantation of the perforating branch of the inferior abdominal artery. Methods 150 healthy volunteers were divided into 20: 29 years old group, 30 ~ 39 years old group, 40 ~ 49 years old group, 50 ~ 59 years old group, 60 ~ 69 years old group. In each group, there were 30 cases with 60 vessels in each group. The blood vessels of inferior abdominal artery were observed by color Doppler ultrasound, and the perforating branches of the inferior abdominal artery were observed. The length of the main trunk was measured, the diameter D _ 1 at the beginning, the diameter D _ 2 at the level of the umbilical cord and the peak systolic velocity of PSV, the diastolic velocity of EDV, the pulsatility index (Pi), the resistance index (RI). Results the 300 inferior abdominal arteries of 150 subjects were all in color Doppler ultrasound. The images clearly showed that .283 inferior abdominal arteries originated from 17 femoral arteries from the external iliac artery. The inferior abdominal artery ascended inward from the midpoint of the inguinal ligament. After the external margin of the rectus abdominis, the inferior symphysis of the ventral transverse fascia entered into the sheath of the rectus abdominis and rose to the top of the umbilical cord between the rectus abdominis and the posterior sheath of the rectus abdominis. The inferior abdominal artery was measured and perforated by 3.85 卤0.87 branches. The perforating branch was set as the perforating branch with diameter 鈮，
