Multidetector-row computed tomography angiography for the diagnosis of anomalous pulmonary venous drainage: an initial experiment* Angiotomografia com múltiplos detectores no diagnóstico de drenagem venosa pulmonar anômala: experiência inicial

OBJECTIVE: We aimed to determine if multidetector-row computed tomography angiography is an effective and non-invasive method for diagnosing anomalous pulmonary venous drainage. MATERIALS AND METHODS: We performed a retrospective review of 2905 cases from July 2003 to November 2007 in which cardiac multidetector-row computed tomography was used. Of the cases, 393 evaluated congenital cardiopathy, with the others (2512) evaluating the coronary arteries. RESULTS: Anomalous pulmonary venous drainage was found in 21 cases, with 7 (33.3%) from total anomalous pulmonary venous drainage (3 supracardiac, 3 infracardiac and 1 cardiac), and 14 (66.7%) from partial anomalous pulmonary venous drainage. CONCLUSION: Multidetector-row computed tomography angiography can be useful for diagnosing the described anomalies because of its non-invasiveness, and its ability to evaluate intraand extra-cardiac structures. The technique allows a thorough study of the thoracic anatomy and contributes to surgical conduct, consequently improving patient prognosis, in particular by allowing the diagnosis of clinically unsuspected malformations.
