Botal's Duct [Ductus Arteriosus (Botalli), Bna; L. Botallo, 1530-1600, Italy. Surgeon And Anato]

Batalla ducts (Ductuses Arteriosi, translated into Russian as “vascular duct”), named after the Italian Lodovico Batalla, are anatomical formations that are a narrow canal connecting the pulmonary artery (coming from the left ventricle) and the aorta (coming from the right ventricle). It is one of two large arterial ducts present in the fetus in the first weeks of life, which remains open after birth. The function of Bpa is to control arterial circulation during fetal life and after birth to help newborns pass through the first stage of development.

Congenital anomalies of the batal ducts lead to various disorders of the cardiovascular system. They can cause health problems in both adults and children. The Battalian ducts are of great importance in the treatment of congenital heart disease (CHD) in children and adults.

The tubal ducts sometimes close after birth, but sometimes they may remain open. Thus, the phenomenon of the “remaining battle” may arise. In such cases, blood may flow through the right ventricle, which can ultimately lead to pulmonary hypertension or congenital heart disease. In some cases, Bpa can block the pulmonary arteries, leading to arterial thrombosis. However, in most cases, the batal canals close by the first months of life. The causes of Bpa dysfunction and obstructive abnormalities are rarely the same.

Under certain conditions, the batallae may remain partially closed, but their role can be significant. Sometimes it is a minor structural factor, while in other cases there is significant pulmonary obstruction
