The greatest risk of crisis life bleeding than esophageal and gastric variceal bleeding in portal hypertension. The two parts of upper gastrointestinal hemorrhage is fierce, large amount of bleeding, if not timely rescue life is in danger at any time. As early as 10 years ago, we started to study the treatment of esophageal variceal hemorrhage of the static problem first carried out esophageal variceal ligation treatment and carried out a series of clinical and basic research, the treatment effect is greatly improved, greatly reduce the mortality of bleeding. For some ligation in the treatment of recurrent problems we have carried out in-depth study on the the recurrence and lower esophagus and esophageal venous wall wear surface proliferation of small blood vessels, based on the above theory, we carried out the new treatment to prevent the recurrence of esophageal varices in the prevention of recurrence of esophageal varices, laser induced esophageal mucosal fibrosis animal Physical and clinical trials. After a follow-up study in recent years, the method of preventing the recurrence of esophageal varices with satisfactory effect, especially the long-term effect is more prominent. Therefore, it can be said that the treatment of esophageal varices has basically been solved.
Now the most difficult is the gastric varices. As early as 5 years ago, we began to study gastric varices, first of all to prick treatment and surgical treatment of gastric varices set, but the effect is not satisfactory, the main problem is the recurrence of bleeding or severe illness can not tolerate surgery. We carry out nearly two or three years of gastric varices group tissue glue (hardener) injection in the treatment of varicose vein vascular sclerosis group to stop bleeding, good hemostatic effect. But there are a few patients with pulmonary embolism complications by three-dimensional imaging. We found that some patients with gastric varices of gastric bypass -- kidney and when can the tissue glue injection into the inferior vena cava through this channel, the pulmonary artery due to pulmonary embolism. We have tried, in the monitoring of DSA catheter implantation for gastric renal shunt - ring channel plugging, and gastric varices Hardening treatment. At present we have completed 5 cases, no complications of ectopic embolism. There are other ways to block, we are also exploring.
