Abstract:
Objective To offer the theoretical evidence for clinical application,we observed the changes of angiographic appearances and local pathological changes before and after embolizing the left gastric artery with mitomycin C gelatin microspheres (MMC-MS).Methods Catheter was delivered into the left gastric arteries via femoral artery and then infused MMC-MS.The angiographic appearances and local pathological changes were observed immediately,and then with follow up of 6～8h,24h,72h,1w,2w and 4w. Results The minute arterioles of tunia mucosa and tela submucosa were mainly embolized inducing edema and focal necrosis.With the degradation of MMC-MS,the damage of gastric tissue was alleviated but turned normal after 4 weeks.The results of DSA showed that no recanalization of the embolized vessels occurred after one week of emboliatdion but revealed one recanalization after two weeks and two in four weeks.Conclusions The damage of tissue induced by embolizing the left gastric artery with MMC-MS can be recovered.The application of the MMC-MS is feasible.
