Pulmonary pressure is one of the most important parameters in the postoperative follow-up of patients who have undergone the Glenn procedure. Platelet activation markers, which are inexpensive and easily accessible blood count parameters, have been shown to be associated with the aetiology and pathogenesis of primary pulmonary artery hypertension. We examined the relationship between platelet activation markers and pulmonary pressures in the early postoperative period of patients who underwent the Glenn procedure.
Eighty-five patients who underwent the Glenn procedure in our clinic between January 2011 and March 2020 were included in the study retrospectively. Fifty-one patients were male and 34 were female, and age varied from 4 to 416 months, with a mean of 28.64 ± 51 months.
Patients with increased pulmonary blood flow on palliation before Glenn surgery had higher mean platelet volume values. However, no correlation was found between pulmonary pressures and platelet activation markers in the early postoperative period.
There was not similar study evaluating platelet activation markers in the paediatric age group before and after postoperative Glenn surgery in the literature. Therefore, even if platelet activation markers provide information about the pulmonary bed, they may be misleading due to other reasons that trigger bleeding and inflammatory processes in the early postoperative period.
