Since 1986, intraoperative coronary venography was performed on 24 patients before and after undergoing portoazygos disconnection for portal hypertension. Before the disconnection the portal vein was found to be communicated with cardial and esophageal veins by two pathways, i.e. from the esophageal branches of the coronary vein to the esophageal varices, and from the gastric branches of the coronary vein to the esophageal varices by way of the gastric intramural venula. The portal blood flow was postulated to be hepatofugal because the portal trunk could not be seen on the venography. Coronary venography done after the disconnection found no pericardial and esophageal varices but the portal vein with hepatoportal blood flow. The authors come to the conclusion that the operation has the advantage of both complete disconnection between the portal vein and the cardio-esophageal varices, thus preventing the varices bleeding, and increasing hepatic blood flow.
自1986年以来，对24例门静脉高压症患者在进行门奇静脉断流术前后进行了术中冠状静脉造影。断流术前发现门静脉通过两条途径与心静脉和食管静脉相通，即从冠状静脉的食管支至食管静脉曲张，以及从冠状静脉的胃支经胃壁内小静脉至食管静脉曲张。由于静脉造影未见门静脉主干，推测门静脉血流为离肝血流。断流术后进行的冠状静脉造影显示无心包和食管静脉曲张，但门静脉有肝门静脉血流。作者得出结论，该手术具有门静脉与心-食管静脉曲张完全断流的优点，从而防止静脉曲张出血，并增加肝血流。
