Abstract:
Objective To evaluate the ability of multi-slice spiral CT angiography(MSCTA)in showing the celiac trunk and its degree branches,and the value of MSCTA in preoperative evaluation of laparoscopic-assisted gastrectomy for advanced gastric carcinoma.Methods A total of 25 consecutive patients scheduled for laparoscopic-assisted gastrectomy with D2 lymph node dissection were evaluated by MSCT,CT angiography(CTA)were reconstructed separately using a volume rendering algorithm(VR).The space anatomy characteristics of celiac artery and its degree branches were evaluated according to the CTA results,and with anatomy information,laparoscopic-assisted gastrectomy with D2 lymph node dissection was processed with references to anatomy.Results In all the 25 cases,the left gastric artery and gastroduodenal artery were accurately identified on MSCTA.In 12 of them,the right gastric artery was accurately identified.The origin of the spleen artery is relatively constant.Laparoscopic-assisted gastrectomy with D2 lymph node dissection was successfully completed without conversion to open surgery in all the cases.The reconstructed celiac trunk and branches are identical with anatomy.Conclusions Three-dimensional CTA using MSCT clearly reveals the anatomy of celiac artery and their space structure.It plays an important role in guiding lymph node dissection during laparoscopic-assisted gastrectomy for advanced gastric carcinoma.
