Thoracic aortic coarctation with asbestos-induced pleural fibrosis presenting as lower limb claudication

Abstract

Asbestos exposure is a well-documented cause of pulmonary diseases. However, its systemic effects, particularly on the cardiovascular system, are less understood. We expose a case that highlights an unusual cardiovascular manifestation in a patient with a history of pleural asbestosis compressing the aorta and clinically manifested as lower limb claudication. A 65-year-old individual presented with bilateral short-distance lower extremity claudication. The patient’s clinical presentation prompted advanced imaging studies, including CT angiography, to assess the extent of vascular involvement. The imaging confirmed the presence of substantial calcification and narrowing of the thoracic aorta. The patient had a documented history of pleural asbestosis. This case underscores the potential for asbestos-related diseases to extend beyond pulmonary manifestations, affecting cardiovascular health. The observed aortic calcification and coarctation represent an atypical progression of asbestosis related pathology.
