Crossed pulmonary arteries associated with persistent truncus arteriosus and right aortic arch on the three-dimensional computed tomographic imaging/Uc boyutlu bilgisayarli tomografik goruntulemede persistan trunkus arteriyozus ve sag aortik arku ile iliskili caprazlasan pulmoner arterler.

A 33-year-old gravida 2, para 1 woman was referred to our pediatric cardiology unit at the 19th week of gestation with suspicion of cardiac anomaly. Fetal echocardiography revealed type 1 truncus arteriosus anc right aortic arch. A female infant weighing 3200 gram was delivered a 38th week of gestation. Her cardiac pathology was confirmed by postna tal echocardiography. Moreover, we suspected crossed pulmonary arter ies, because the pulmonary bifurcation was not shown by two-dimen sional echocardiography. A three dimensional (3D) contrast-enhanced 64-multislice computed tomography (MSCT) revealed crossed pulmonan arteries. The main pulmonary artery arose from the posterior aspect o the truncus and the ostium of the left pulmonary artery was lying to the right and superior to the right pulmonary artery (Fig. 1, 2).



Crossed pulmonary arteries are a rare cardiac abnormality that often associates with congenital heart disease such as ventricular septal defect, right aortic arch, interrupted aortic arch and truncus arteriosus and chromosomal abnormalities such as chromosome 22q11 deletion. Detection of crossed pulmonary arteries may be an important marker to the diagnosis of cardiac and chromosomal abnormalities. The failure of imaging bifurcation of the pulmonary arteries on echocardiography might be a clue for the diagnosis of crossed pulmonary arteries.
