Objective: Different surgical techniques are applied for the treatment of aortic coarctation. Extended end-to-end anastomosis and subclavian flap aortoplasty are frequently preferred procedures. The aim of this single-center study was to analyze and evaluate the results of two different surgical procedures in infants who underwent aortic coarctation repair.

Material and Method: Surgical repair results of 72 patients who underwent extended end-to-end anastomosis and subclavian flap aortoplasty were evaluated retrospectively. The study was designed as nonrandomized, crosssectional. Extended end-to-end anastomosis (group 1) was performed in 41 (56.9%) patients and subclavian flap repair (group 2) in 31 (43.1%) patients.

Results: Sixty-one,six percent of the total of 72 patients were male (44 boys/28 girls).The median age of the patients was 46 days (6 – 330 days) and their mean body weight was 4193±1436 grams.All patients were followed up for an average of 13.7 months (1-45 months) postoperatively.In the postoperative follow-up, balloon angioplasty was performed in 1 (2.4%) patient in group 1 and in 2 (6.5%) patients in group 2 due to recoarctation.Recoarctation repair was performed in one patient in group 1, due to the persistence of the gradient.The most common postoperative complications were pneumonia (8.3%) and chylothorax (4.2%).There was no significant difference between the groups in terms of postoperative mechanical ventilation time, length of stay in the intensive care unit, and length of hospital stay.A significant negative correlation was found between the body weights of the patients, mechanical ventilation duration, and length of stay in the intensive care unit (r= -0.36, p= 0.002, r= -0.24, p= 0.037,respectively).

Conclusion: Extended end-to-end anastomosis and subclavian flap aortoplasty are effective procedures for aortic coarctation repair.
