目的 研究肝 胃动脉 (hepatogastricartery ,HGA)的DSA表现特征 ,探讨其在肝癌经导管动脉内化疗栓塞 (transcatheterarterialchemoembolization ,TACE)术中的意义。方法 回顾分析 10 0 0例肝动脉DSA造影片 ,将起源于肝固有动脉 (properhepaticartery,PHA)以远各级肝动脉的胃及十二指肠的供血动脉命名为HGA ,并根据其走行方向及分布范围的不同 ,进一步将其分为胃右动脉 (rightgastricartery ,RGA)、迷走胃左动脉 (aberrantleftgastricartery ,AbLGA )、迷走胃十二指肠动脉 (aberrantgastroduodenalartery ,AbGDA)、迷走胃网膜右动脉 (aberrantrightgastroepiploicartery ,AbRGEA)、十二指肠上动脉 (superiorduodenalartery ,SDA)及其他不易明确命名的HGA等。分别统计其发生率 ,描述其起源、走行、分支、分布等解剖学特征。结果 10 0 0例中 ,740例存在 1支以上的HGA ,占 74%,共显示839支HGA ,其中RGA 6 82支 (81 2 9%,6 82 / 839) ,AbLGA 84支 (10 0 1%,84/ 839) ,SDA 45支 (5 36 %,45 / 839) ,AbGDA 2 1支 (2 5 0 %,2 1/ 839) ,AbRGEA 1支 (0 12 %,1/ 839) ,其他HGA 6支 (0 72 %,6 / 839)。839支HGA中 ,起源于PHA 412支 (4 9 11%,412 / 839) ,起源于肝左动脉 (lefthepaticartery,LHA) 314支(37
Objective To study the DSA features of hepatogastric arterial (HGA) and explore its significance in transcatheter arterial chemoembolization (TACE). Methods A retrospective analysis of 1000 cases of hepatic arterial DSA was performed. Hepatic and duodenal feeding arteries originated from the hepatic artery (PHA) at all levels were designated as HGA, and their directions of travel were The range of distribution is further divided into right gastric artery (RGA), left aortic left gastric artery (AbLGA), avarant gastroduodenal artery (AbGDA), and right aortic gastroepiploic arteries (aberrantright gastroepiploic arteries). (AbRGEA), superior duodenal artery (SDA), and other HGAs that are not easily named. The incidence rate was calculated separately, and the anatomical features such as its origin, running, branching, and distribution were described. Results Of the 100 cases, 740 cases had more than one HGA, accounting for 74%, showing a total of 839 HGAs, of which RGA was 6 82 (81 2 9%, 6 82 / 839), and AbLGA was 84 (10 0 1 %, 84/ 839), SDA 45 (536%, 45/839), AbGDA 2 1 (25%, 2 1/839), AbRGEA 1 (0 12%, 1/839), others HGA 6 (0 72%, 6 / 839). Among 839 HGAs, 412 originated from PHA (4 9 11%, 412/839) and 314 from left hepatic artery (LHA).
