Patient's question:
My friend's child has been crying non-stop recently. When they went to the hospital for a check-up, the attending doctor said the child has developed complete pulmonary venous anomalous connection in children. However, none of us understand what this medical history means or what the cause is. Can complete pulmonary venous anomalous connection in children be treated?Doctor's answer:
The etiology of this disease occurs in the early stage of embryonic development. The pulmonary vascular bed is connected to the total venous system and the umbilical vitelline vein system. Subsequently, the right main vein is derived to the superior vena cava, without a fused vein, and the left main vein is derived to the left superior vena cava. The coronary sinus and the umbilical vitelline vein system originate from the inferior vena cava, the ductus venosus, the portal vein, etc., and have no direct connection with the primitive heart on the 25th to 27th day of pregnancy. In subsequent development, the pulmonary veins are not included. The bronchial veins remain attached.
