Özet
Objectives: This study aimed to provide a detailed account of the mid-term outcomes of the modified Brock procedure, a recently implemented procedure for patients with cyanotic congenital cardiac disease in our institution, with a particular focus on the clinical follow-up data. Patients and methods: A total of 14 patients (7 males, 7 females; median age 4.5 years; range, 1 to 14.5 years) underwent the modified Brock procedure between January 2014 and January 2024. Relevant information was collected retrospectively, with a focus on the sizes of the pulmonary arteries. Results: The preoperative median oxygen saturation and McGoon ratio were 71.5% (69.5 to 72.5%) and 1.35 (1.2 to 1.4), respectively. The postoperative course was uneventful. The median follow-up was seven years, and there was only one mortality two months after the operation. The complete repair was done in four patients during follow-up, with a median of 17.5 months after the initial procedure. The median McGoon ratio was 2 (1.9 to 2.125) in these patients. The postoperative median oxygen saturation was 93% (86.25 to 94.25%) and the median McGoon ratio was 1.6 (1.5 to 1.7) in patients awaiting complete repair surgery. Conclusion: We concluded that the modified Brock procedure, when implemented with meticulous technique, is a viable choice in both short- and mid-term follow-up for palliative repair in patients with pulmonary artery anatomical constraints that preclude complete repair.
