We present a case of type I truncus arteriosus communis characterized by the horizontal origin of the main pulmonary artery from the common trunk and by a winding course up to a total length of 11.5 cm to the point of bifurcation of the pulmonary artery. Other than cyanosis the patient had a normal clinical history, which was followed for 20 years. The length of the main pulmonary artery could be related to the lower site of the incomplete septation of the common trunk, and it seems that hemodynamic factors contributed to this unusual configuration.
我们报告一例I型共同动脉干病例，其特征为肺动脉主干从共同动脉干水平发出，并呈迂曲走行，直至肺动脉分叉处全长达11.5 cm。除发绀外，患者临床病史正常，随访20年。肺动脉主干的长度可能与共同动脉干不完全分隔的较低位置有关，血流动力学因素似乎促成了这种异常形态。
