INTRODUCTION Isolated aortic coarctation performed through a left thoracotomy resection and end-to-end anastomosis results in low mortality and morbidity rates. Recoarctation and late hypertension are among the most important complications after such repairs. In this study, we reviewed the results of children who underwent left-side thoracotomy to correct an isolated aortic coarctation. METHOD A consecutive sample of 90 patients who underwent resection and extended end-to-end anastomosis through a left-side thoracotomy in our centre between 2011 and 2021 was retrospectively analysed. The patients' preoperative characteristics, operative data, and post-operative early and long-term results were examined. RESULTS All patients underwent resection and extended end-to-end anastomosis. A pulmonary artery band was applied simultaneously to three (3.3%) patients, and an aberrant right subclavian artery division was applied to one (1.1%) patient. The mean cross-clamp time was 29.13 ± 6.97 minutes. Two (2.2%) patients required reoperation in the early period. Mortality was observed in one (1.1%) patient in the early period. Eight (8.8%) patients developed recoarctation, of whom four (4.4%) underwent reoperation and four (4.4%) underwent balloon angioplasty. Twenty-two (26.8%) patients received follow-up antihypertensive treatment. The mean follow-up period was 41.3 ± 22.8 months. No mortality was observed in the late period. CONCLUSION Isolated coarctation is successfully treated with left-side thoracotomy resection and an extended end-to-end anastomosis technique with low mortality, morbidity, and low long-term recoarctation rates. Long-term follow-up is required due to the risks of early and late post-operative recoarctation, which requires reintervention.
