title: [Clinical significance of multi-slice spiral CT angiography in radical resection of gastric cancer].
abstract: OBJECTIVE
  To explore the clinical significance of preoperative abdominal multi-slice spiral CT angiography (MSCTA) in radical resection of gastric cancer.
  
  
  METHODS
  One hundred and three patients with gastric cancer were divided into two groups according to their desires. Group I( included 57 patients who underwent preoperative MSCTA and group II( included 46 patients who underwent surgery without preoperative MSCTA. All these patients were operated by the same surgical team.
  
  
  RESULTS
  Six patients(10.5%) with abnormal gastric artery in group I( were discovered. The diagnostic concordance rate between MSCTA and intraoperative findings was 100% in group I( in the locations and alignments of main perigastric vessels and their relationship with cancer lesions. Operative time in group I( was shorter than that in group II( [(206 ± 23) min vs. (257 ± 32) min, P=0.044]. Operative time [(190 ± 50) min] of patients with abnormal gastric artery of group I( was shorter than that [(255 ± 62) min] of patients with abnormal gastric artery discovered during operation of group II( (P=0.048). However there were no differences in blood loss, extent of lymph node dissection, complication rate, length of hospital stay, and hospitalization cost between the two groups(P>0.05).
  
  
  CONCLUSIONS
  Preoperative MSCTA is beneficial to the evaluation of vascular structure of the cancer and the adjacent tissues, which may reduce postoperative complications.
