Renal cysts in abdominal aortic aneurysm diagnosed by Doppler ultrasound

Abstract

Introduction: The relation between the presence of renal cysts and abdominal aortic aneurysm is a question to be clarified, and there is no literature on the subject.

Objective: To estimate the relation between the presence of renal cysts and abdominal aortic aneurysm in patients treated at the National Institute of Angiology and Vascular Surgery.

Methods: A descriptive longitudinal study was conducted in the period 2021-2022 in patients with a clinical and ultrasound diagnosis of abdominal aortic aneurysm. The universe was made up of patients who attended the Doppler Ultrasound Department with a clinical diagnosis of abdominal aortic aneurysm. The sample consisted of 152 patients. The Chi-square test and the risk estimation method were used to calculate the odds ratio.

Results: The mean age was 70.1 ± 5.6 years; males predominated, with 27 cases with cysts out of a total of 41; abdominal pain was the most frequent clinical manifestation (99 cases); and the cardiovascular risk factor that occurred the most was smoking (97 patients). The predominant ultrasound characteristics were: infrarenal artery aneurysm (107 cases) and very small diameter with 17 cases and odds ratio of 4.53; it was considered risky, as it was the bilateral intake of the iliac arteries, with an odds ratio of 7.56 (5 cases).

Conclusions: The presence of abdominal aortic aneurysm is independent of whether or not renal cysts are present. These two pathologies were only related in terms of bilateral intake and very small diameter of the aneurysm
