Orifice of Pulmonary Veins

Orifices of the pulmonary veins or Ostia venarum

Pulmonary veins are vessels that carry blood from the lungs to the heart. They begin in the lungs and open into the right atrium, which is the lower part of the heart.

Endovascular angiosurgery of the pulmonary veins currently consists of the following techniques: percutaneous “sclero-thrombectomy” access to the pulmonary veins by performing both minimally invasive and reconstructive interventions on the left septal trunk; low-traumatic access to the pulmonary venous systems in the system of pulmonary-arterial hemodynamics; reconstruction of the pulmonary vein system in conditions of low surgical aggression using minimally invasive endovascular techniques. The use of new instruments that make it possible to perform catheter intervention involves the application of an artificial apparatus to create a single blood flow through the vessels of the pulmonary circulation. Catheter interventions on large veins of the pulmonary circulation and pulmonary arteries are performed under short-term intravenous anesthesia while maintaining
