Preoperative evaluation of the aberrant artery in intralobar pulmonary sequestration using multidetector computed tomography angiography.

Intralobar pulmonary sequestration is a rare congenital malformation of the lung, and identification of the aberrant artery from the systemic circulation to the sequestered lung is crucial in definitive surgery. Nowadays, various noninvasive imaging modalities such as helical computed tomography, magnetic resonance imaging, and color Doppler sonography have been developed. Among them, multidetector computed tomography angiography, which allows simultaneous imaging of the aberrant artery and venous drainage, has the potential to become the first-line examination in the preoperative assessment of pulmonary sequestration. In this article, we describe 2 cases of intralobar pulmonary sequestration, in which multidetector computed tomography angiography was useful in the preoperative management and surgery was successfully performed.
