The　objective　of　this　study　is　to　acquire　CT　images　of　the　celiac　artery　by　64-multi-slice　spiral　CT　angiography　(64-MSCTA)　in　gastric　cancer　patients　to　facilitate　gastric　cancer　surgery.　Preoperative　64-MSCTA　was　performed　to　observe　the　origin,　course　and　anatomical　variations　of　the　celiac　artery　and　vascular　calcifications　in　102　gastric　cancer　patients.　(1)　The　celiac　trunk　mostly　arose　at　the　level　between　the　12th　thoracic　vertebra　and　the　1st　lumbar　vertebra;　the　mean　inferior　angle　with　the　abdominal　aorta　was　63.5A　degrees　(14A　degrees-159A　degrees),　the　mean　length　was　36.29　mm　(5.80-73.58　mm),　and　its　course　showed　many　styles.　(2)　Of　102　gastric　cancer　patients,　34　patients　(33.33　%)　were　observed　with　celiac　artery　variations　of　whom　there　were　27　patients　with　anatomical　variations　of　the　hepatic　artery,　3　patients　with　anatomical　variation　of　the　left　gastric　artery　and　1　patient　with　anatomical　variation　of　the　splenic　artery;　in　1　patient,　the　celiac　trunk　and　the　superior　mesenteric　artery　originated　from　a　common　trunk.　In　other　cases,　it　was　observed　with　another　variation.　(3)　The　abdominal　aortic　calcified　plaque　was　observed　in　48　patients　(47.1　%),　and　among　them,　34　patients　were　more　than　60　years　old,　and　the　existence　of　the　abdominal　aortic　calcified　plaque　was　related　to　age,　significantly　(P　＜　0.01).　The　64-MSCTA　largely　improves　our　understanding　of　the　origin,　course　and　anatomical　variations　of　the　celiac　artery　and　vascular　calcifications　in　individual　patient　with　gastric　cancer.　It　is　recommended　that　the　64-MSCTA　of　the　celiac　artery　should　be　classified　as　a　routine　preoperative　procedure　in　gastric　cancer　patients.
