CROTI, Ulisses Alexandre et al. Computed tomography in late evaluation of surgical treatment of pulmonary veins total anomalous connection. Rev Bras Cir Cardiovasc [online]. 2011, vol.26, n.4, pp. 532-543. ISSN 0102-7638. http://dx.doi.org/10.5935/1678-9741.20110042.
OBJECTIVE: To evaluate if the findings of multislice computed tomography (MSCT) are associated with clinical and laboratory tests routinely used in the late follow-up of children undergoing surgical treatment of total anomalous pulmonary venous connection (TAPVC). METHODS: From January 2002 to December 2007, 12 patients operated due to CATVP were evaluated with history, physical examination, chest X-ray, electrocardiogram, echocardiography and MSCT. Specific changes observed in each one of these tests were identified and compared with MSCT qualitative findings. RESULTS: Eleven patients were in functional class I (NYHA), three had nonspecific murmurs, and three were below the 15th percentile of weight and height. Two had pulmonary field abnormalities and three had a slight increase of the cardiac area in the X-ray examination. In the electrocardiogram, one patient had right ventricular overload and one had junctional rhythm. All echocardiograms were within the normal range, except for one patient with stenosis between the superior vena cava and right atrium. MSCT was completely normal in four patients, three had compression of the pulmonary veins and four had significant caliber reduction, which correlated with the other findings. Thus, MSCT showed a sensitivity of 87.5%, specificity of 0.75%, positive predictive value of 87.5%, negative predictive value of 75% and accuracy of 83.3% to demonstrate anatomic changes compared to changes in the physical examination or other additional tests. CONCLUSION: MSTC may provide valuable information and complement the diagnosis of possible anatomical and functional changes in the late follow-up of patients undergoing surgical repair of TAPVC.
