摘要
目的探讨胃十二指肠动脉的超声表现和探查方法及其在临床应用的意义。方法观察200例正常人的胃十二指肠动脉,注意其与肝总动脉的关系、毗邻关系、在胰腺内的走行、回声特点、内径正常值、超声所能探及的长度范围。50人进行了彩色多普勒探查。结果仰卧位、左侧卧位及饮水充盈胃窦三种方法联合应用,使胃十二指肠动脉的总显示率为97.5%(195/200),且图像清晰。胃十二指肠动脉起于肝总动脉,经门静脉的前方向下走行于胰腺包膜下或实质内,呈典型的动脉回声图像,内径值为(0.34±0.07)cm,超声所能探查的长度为(2.93±0.55)cm,血流速度(71±6)cm/s。结论多种体位和方法联合应用,以及耐心细致地扫查,胃十二指肠动脉的显示可以达到满意的效果,获得正常声像图。
Objective To investigate normal ultrasonography of the gastroduodenal artery and the ultrasonic examination method and its value in clinical application.Methods Two hundred normal volunteers were examined by two-dimensional ultrasonography. Its relation to common hepatic artery, the adjacent relationships in anatomy, the trace in the pancreas, the sonographic feature, the normal inner diameter and the length that could be detected by two-dimensional ultrasonography were observed .Color Doppler were applied on 50 volunteers too.Results Different body positions(supine position, left lateral position )and drinking water were applied to make the image clear and the visualization rate of the gastroduodenal artery up to 97.5%.The gastroduodenal artery was origined from the common hepatic artery, it was of typical features of arterial type which passed by the anterior of the portal vein and descended under the peplos or in the parenchyma of the pancreas .The inner diameter was 0.34±0.07cm,the length that could be detected was 2.93±0.55cm,and the range of the velocity was 71±6cm/s.Conclusion Conjunction of various body positions and different maneuvers can improve the visualization rate of gastroduodenal artery up to a satisfied effect and provide clear normal sonograms of the artery.
