Angiomegaly and arterial aneurysms.

Angiomegaly is characterized by an alteration in the elastic component of arterial and venous vessels determining their elongation and tortuousness. This involves an increased risk of thromboembolism and aneurysmal degeneration in affected subjects, even if they have been asymptomatic for a long time. The aim of this study is to demonstrate the correlation between angiomegaly and aneurysmal disease. A total of 163 patients suffering from a peripheral arterial aneurysm were included, 74 of these with an iliac aneurysm, 41 with a femoral aneurysm and 48 suffering from popliteal aneurysm. All patients were examined by color Doppler ultrasonography (CDU) and angio-CT with contrast medium. Eighteen cases of arteriomegaly were diagnosed, and the prevalence in the examined population was 11%. This study demonstrates the close association existing between aneurysms in peripheral arteries and arteriomegaly. Peripheral arterial aneurysms in association with arteriomegaly involve an increased risk of complications like thrombosis, embolism and rupture. The showed familiarity in the arteriomegaly incidence leads to predisposition of screening programs, using CDU, among relatives of patients affected by arteriomegaly and/or peripheral arterial aneurysms.
