OBJECTIVE: To evaluate dilatation of visceral arteries secondary to anomalies and collateral circulation.DESIGN: Case report.SETTING: Department of Vascular Surgery, University Hospital.PATIENTS: Two patients with secondary visceral aneurysms were reported. First patient (case 1) had a mid-aortic dysplastic syndrome with multiple aneurysms of the celiac trunk and right renal artery. Other patient (- case 2) presented an inferior pancreaticoduodenal artery aneurysm associated with proximal common hepatic artery occlusion.INTERVENTIONS: The case 1 was submitted to aortic and left renal artery angioplasty (PTFEE), while in the case 2 the resection of aneurysm was performed.RESULTS: Both patients had complete resolution of symptoms and are alive today.CONCLUSIONS: Clinical observations confirmed the development of visceral artery aneurysms secondary to arterial hypertension and collateral circulation.
