1) In most cases the esophageal anastomosed branches and the cardiac branches of the coronary vein of the stomach are given off from the arc of the vein. Anatomically, and not taking into account the direction of the blood flow there, the esophageal anastomosed branches form on their further course the veins around the lower esophagus to be anastomosed with the lower submucosal venous plexus of the esophagus. This venous plexus is anastomosed with the middle and upper submucosal veins of the esophagus and communicates with certain branches of the Vena cava through the thoracic esophageal veins. The veins around the lower esophagus are never anastomosed direct with V. longitudinalis and other veins as examined in those 50 normal dead bodies. The cardiac branches are also anastomosed with the lower submucosal venous plexus of the esophagus.
2) In cases in which the portal system is normal again, the Vv. gastricae breves are anastomosed with the lower submucosal venous plexus of the esophagus. In portal hypertension the Vv. gastricae breves frequently serve as an important route by which the blood is sent into the esophageal varices. It must be noted that the Vv. gastrcae breves cannot be completely removed by splenectomy alone in some cases.
3) Investigation in 18 cases has shown that the arc of the coronary vein of the stomach is in no close proximity of the stomach branches of the vagus, and that our technique used for blood flow interruption has no serious effect on the nerve.
4) Examination in 20 cases has proved that the V. longitudinalis has no valves in it.
