Abstract

Objective: Mechanical damage resulting from aortic dissection creates a thrombus in the false lumen, in which platelets are involved. Platelet index is useful for the function and activation of platelets. The aim of this study was to show the clinical relevance of the platelet index of aortic dissection.

Methods: A total of 88 patients diagnosed with aortic dissection were included in this retrospective study. Demographic data and hemogram and biochemistry results of the patients were determined. Patients were divided into two groups: deceased and surviving patients. The data obtained were compared with 30-day mortality. The primary outcome was the relationship of platelet index with mortality.

Results: A total of 88 patients, 22 of whom were female (25.0%), diagnosed with aortic dissection, were included in the study. It was determined that 27 (30.7%) of the patients were mortal. The mean age of the entire patient group was 58±13 years. According to the DeBakey classification of aortic dissection of the patients, the percentages of the 1-2-3 type were determined as 61.4, 8.0, and 30.7%, respectively. Platelet index was not found to be directly related to mortality. Increase in age, decrease in bicarbonate value, and presence of diabetes mellitus were associated with mortality.

Conclusion: Although there were no significant changes in platelet index in aortic dissection, neutrophil/lymphocyte ratio and platelet/lymphocyte ratio were found to be high in line with the literature. In particular, the presence of advanced age diabetes mellitus and decrease in bicarbonate are associated with mortality.
