MRI in guidance for sclerotherapy of gastric varices and evaluation on early treatment response

Objective To explore the value of MRI in guidance for sclerotherapy of gastric varices bleeding under gastroscopy evaluation on its early treatment response.Methods Totally 73cases of gastric varices bleeding who received sclerotherapy under gastroscopy were collected.The extent of gastric varices and the blood supply as well as drainage pathways were estimated with MRI.According to MRI,the dosage of curing agent of sclerotherapy was calculated.After sclerotherapy,MR was performed again.Volume of gastric varicose veins and diameter of left gastric vein before and after treatment were compared.Curative evaluated under gastroscopy and MRI were compared.Results MRI could comprehensively assessed the extent and volume of gastric varicose vein before treatment,including blood supply and drainage pathways. MRI showed that the volume of gastric varicose veins and diameter of left gastric vein reduced after sclerotherapy(both P 0.01).Between MRI and gastroscopy,the judgments invalid were consistent,but effective and significant effect were significantly different(P0.01).Conclusion Assessment of gastric varices before sclerotherapy with MRI is helpful to choose reasonable treatment for patients having higher risks for hemorrhage.MRI can observe immediate curative of sclerotherapy,which is more intuitive and comprehensive than gastroscopy.
