Differential patterns of atherosclerotic disease in patients with unilateral hemiparesis resulting from poliomyelitis: Case reports demonstrating the possible effect of hemodynamics

The relative importance of hereditary and mechanical factors in the pathogenesis of aneurysms remains as controversial today as it was two decades ago. The cases of two patients with unilateral paresis resulting from poliomyelitis who presented with abdominal aortic aneurysms are reported. In addition, each patient had iliofemoral aneurysms contralateral to and iliofemoral occlusive disease ipsilateral to, their affected extremity. The two cases detailed within this report suggest that hemodynamic forces may alter the pattern of disease in arteries affected by arteriosclerosis.
