Nineteen children had unilateral dilatation of the internal mammary artery associated with an intrathoracic lesion on the same side. Dilatation of one internal mammary artery to a calibre more than twice that of the artery on the other side is a sign of an intrathoracic pathological finding on the same side. However, when the arteries have the same calibre an intrathoracic pathological process is not excluded. Dilatation occurs independently of the vascular supply of the pathological process by systemic collaterals. A share in the collateral supply from the pulmonary circulation is specially characteristic.
19名儿童出现单侧乳内动脉扩张，且同侧胸腔内有病变。一侧乳内动脉扩张至管径超过另一侧动脉两倍以上是同侧胸腔内有病理发现的征象。然而，当双侧动脉管径相同时，也不能排除胸腔内存在病理过程。乳内动脉扩张独立于病理过程的体循环侧支血管供应。特别典型的是肺循环参与侧支供血。
