Figure 1. a-d.

Computed tomography (CT) image and angiographies of a 69-year-old woman who complained of hemoptysis. A coronal-reformatted image of CT angiography (a) demonstrating the ectopic left bronchial artery (arrowheads) originated from the thyrocervical trunk. Selective angiography of the ectopic left bronchial artery (b) showed hypertrophied vessels (black arrowheads) and shunt to the pulmonary vein (arrow). Note that the microcatheter (white arrowhead) in the culprit artery had advanced deep enough to perform safe embolization. After catheterization of the orthotopic right bronchial artery, selective angiography (c) presented the bronchial artery hypertrophy (arrowheads) and abnormal lung staining (arrow). Celiac angiography (d) demonstrated the hypertrophied esophageal branch (arrowheads) of left gastric artery associated with abnormal lung staining (arrow). The patient was successfully treated using transradial embolotherapy.
