Abstract

PURPOSE To detect pathologies in coronary arteries by computed tomography angiography (CTA) in survivors of childhood Hodgkin's lymphoma who have been treated with radiotherapy and/or cardiotoxic agents. PATIENTS AND METHODS Patients with HL who have been in remission for at least 2 years after completion of therapy were included. CBC, lipid profile, urine analysis, brain natriuretic peptide, troponin-T, creatinine kinase-myocardial band, ECG, telecardiography, echocardiography, and CTA of the patients were performed. Cardiac vascular abnormalities were noted. Results A total of 119 patients were included in the study. In 19 patients (16%), we found coronary artery abnormalities. There was a significant difference between the patients who received mediastinal radiotherapy and those who did not (P = .02). By multivariate analysis, in patients receiving mediastinal radiotherapy the risk of developing a coronary artery abnormality was found to increase 6.8 times compared with patients who did not receive mediastinal radiotherapy (P = .009). Stent implantation was performed in a 28-year-old patient because of critical stenosis in right coronary. In two patients some irregularities were detected both in CTA and conventional angiography, and they remained in close follow-up. A 22-year-old patient whose CTA showed critical stenosis in his left anterior descending artery refused the conventional angiography. CONCLUSION To our knowledge, this is the first large study using CTA for detection of coronary abnormalities in patients treated for HL in pediatric age group. Coronary CTA is a minimally invasive tool for early diagnosis of coronary artery disease in patients who were treated with mediastinal radiotherapy and/or cardiotoxic chemotherapy.
