[A technic of limited gastric coronary vein embolization under direct vision for treatment of portal hypertension].

Venous embolism of the gastro-cardiac area for the purpose of controlling hemorrhage, as suggested at Liu Xiougong in 1984, was adopted widely by some institutes in our country with a satisfactory outcome although some complications did happen. Forty cases of portal hypertension was treated in this institute since May 1985 with coronary vein embolism plus splenectomy under direct vision. Based on modified Liu's technique and animal experiment, the authors practiced limited gastric coronary vein embolism in 20 cases with a satisfactory result. This procedure may not only block the veins where bleeding may incidentally occur, but also cut off the communications between the veins of the lower esophagus, the fundus of the stomach and the adjacent venous system to minimize the possibility of postoperative complications. The mechanism of blockade and technique of this procedure were described and the ways to prevent complications presented in detail.
