Literature data on the association between the incidence of ruptured abdominal aorta and seasons are contradictory. The influence of climatic factors on the rupture of abdominal aorta is geographically dependent. The aim of this research was the investigation of the connection between the incidence of ruptured abdominal aorta and seasons at the territory of the southern Serbia. In this retrospective study, 59 consecutive patients, who were hospitalized in the Vascular Surgery Clinic, Clinical Center Niš, between 2008 and 2011, were involved, having the rupture of the infrarenal segment of the abdominal aorta. The incidence of the ruptured aneurysm of the abdominal aorta was analyzed with regard to calendar years, seasons and months. There was no significant connection between calendar year (χ2 test=3,836, p=0,28), seasons (χ2 test=3,4, p=0,334) and months (χ2test =11,109, p=0,434) and the incidence of the disease. According to the results of this study, it can be concluded that the incidence of ruptured abdominal aortic aneurysm in the southern Serbia is not related to seasons and months during the year.
