Transection of the pulmonary artery is a surgical procedure primarily performed in newborns who present with specific cardiac and great vessel anomalies. This intervention serves as a palliative measure, providing temporary relief until a more comprehensive surgical repair can be executed. The procedure is indicated when there exists an alternative vascular connection to the lungs, which facilitates the flow of deoxygenated blood into the lungs, allowing for the return of oxygenated blood back to the heart. The surgical approach involves making an incision in the chest to gain access to the heart and the pulmonary artery. Following this, cardiopulmonary bypass is initiated to maintain circulation and oxygenation during the procedure. The main pulmonary artery, also referred to as the trunk, is clamped both above and below the designated incision site, allowing for the transection of the artery. After the transection, the distal and proximal stumps of the pulmonary artery are meticulously repaired using sutures. Finally, chest tubes are inserted to facilitate drainage, and the chest incision is subsequently closed to complete the procedure.
