This study was done to evaluate the clinical implications and results of a prospective protocol using 64-row computed tomographic angiography (CTA) for diagnosis and pre-treatment planning in pulmonary sequestration (PS).
Forty-five patients with suspected PS were referred for CTA examination. The accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of measures used to detect PS were determined by patient-based and aberrant systemic artery-based evaluations. The location, the size and the number of aberrant systemic arteries, and the feasibility of endovascular treatment were analysed. The capability of CTA to provide a working view and the accuracy of measurements in choosing a coil were also assessed.
Digital subtraction angiography and/or surgery revealed PS in 38 patients, and 7 patients had no PS. The patient-based evaluation yielded an accuracy of 97.8 %, sensitivity of 97.4 %, specificity of 100 %, PPV of 100 % and NPV of 87.5 %, in the detection of PS. CTA clearly depicted the PS in all 38 patients, and the aberrant systemic artery was accurately demonstrated in 37 out of 38 patients where endovascular treatment was possible. Working views for endovascular treatment were found in all patients with PS, and the choice of coil was correct in 37 out of 38 patients using CTA.
64-row CTA appears to be effective in terms of supporting accurate diagnosis and pre-treatment planning in PS. CTA is not only able to provide clear visualisation of aberrant systemic arteries but also provides detailed images of abnormal lung parenchyma and the airways.
