[Endovascular embolization of the gastric veins in portal hypertension complicated by esophagogastric hemorrhages].

Through a period from 1981 to 1996 127 roentgen-endovascular embolization of gastric veins were carried out in 95 patients for portal hypertension complicated by esophagogastric bleeding or in its threatening relapse. Group 1 consisted of 73 patients, to whom endovascular treatment was carried out urgently at the background of continuing hemorrhage, in 52 patients--it was delayed and in 21 patients in the nearest posthemorrhagic period. In 73 patients bleeding resulting from embolization was stopped. In the earliest postembolization period recurrence of hemorrhage developed in 6 patients, thus initial hemostatic effect of embolization made up 91.8%, and survival rate--74% (54 from 73 patients of the 1-st group were discharged from the clinic). Group 2 consisted of 22 patients to whom embolization of gastric veins was carried out as an elective procedure. There were bleedings in the anamnesis in the patients of the latter group, and varicose veins of the esophagus with trophic disturbances in esophageal mucosa manifested real treat of the hemorrhage. The survival rate in this group of patients made up 95.5%. The analysis of the results of elective endovascular embolization of gastric veins revealed more favourable results in the nearest postembolization period, than in urgent procedures. Far off results of embolization of gastric veins were followed up in 61 patients (43 patients of the 1st group and 18 patients of the 2nd group). Index of survival up to 6 months made up 87.8%, up to 12 months--80.5%, up to 3 years--57.5% and up to 6 years--19.6%. Hemostatic effect up to 6 months made up 100%, to 12 months--84.6%, to 3 years--54.9%, to 6 years--15.6%.
