Prevalence of Renal Masses Suspected of Malignancy and Adrenal Incidentalomas in Patients With Abdominal Aortic Aneurysm.

Abstract

The aim of our study was to assess the prevalence of renal masses suspected of malignancy and adrenal incidentalomas in patients with abdominal aortic aneurysm based on the computed tomography angiography (CTA). In the retrospective cross-sectional study, the CTA scans of patients with abdominal aortic aneurysms and thoraco-abdominal aortic aneurysms type II-IV were assessed. Patients with thoraco-abdominal aortic aneurysms type I and V and history of abdominal aortic surgery were excluded from the study. Study group comprised 937 patients with a median age of 73.0 years, 83.8% of whom were male. CTA revealed renal tumors in 11 patients (1.2% of the study population) with a median size of 26 mm (interquartile range 20-50). Adrenal incidentalomas were found in 61 patients (6.5% of the study population). In 20 patients (2.1%) adrenal lesions were found bilaterally. In the described cohort, the renal and adrenal tumors were relatively common findings among patients with abdominal aortic aneurysm and thoraco-abdominal aortic aneurysms type II-IV. Both anaesthesiologists and surgeons should be vigilant about the possibility of such coexistence in order to provide the patients with the best possible perioperative care and an optimal surgical modality.
