China's research found that coronary vein anatomical variations that affect bleeding esophageal varices an important factor, reflux is an important sign of bleeding. For the Study of portal hypertension in patients with coronary vein anatomical variation, reflux and clinical significance, Wu and Jiang, and other direct and indirect portal imaging, ultrasound and Doppler pressure observed 200 cases of portal hypertension in patients with coronary vein anatomy, portal pressure And blood flow. The results showed that portal hypertension in patients with single coronary vein of 79.46 percent, double-coronary vein accounted for 20.54 percent, opening at the portal vein, spleen and portal vein splenic vein Interchange were 62.33 percent, 27.35 percent and 8.07 percent, bleeding and broken flow of Bleeding in patients with coronary vein after opening at the main portal vein, refractory ascites no bleeding in the majority of splenic vein; indirect portal imaging showed Ⅱ, Ⅲ level, portal vein thrombosis in patients with active bleeding and coronary vein show rates were 26.19 percent, 56.64 percent , 100% and 100%, bleeding quiescent and non-bleeding intractable ascites, respectively 47.79 percent and 19.05 percent.
