A Case of Pulmonary Artery Aneurysm with Pulmonary Hypertension

ABSTRACT

Clinical experiences of pulmonary artery aneurysm are distinctly rare and current knowledge is mainly derived from autopsy findings. Pulmonary artery aneurysms are associated with congenital heart disease, most frequently patient ductus arteriosus, followed in decreasing order by ventricular septal defect, atrial septal defect. In the remaining cases, such aneurysms are associated mainly with secondary acquired lesions, such as Behcet's disease, bacterial endocarditis, syphilis, tuberculosis, atherosclerosis, vasculitis, hypertension, trauma. Angiography was the gold standard for diagnosing pulmonary artery aneurysms, but MRI imaging has been potentially useful diagnostic modality in demonstrating aneurysm and other fine pathologic processes with high resolution. Surgery was main, but there are no firm guidelines for optimal treatment of pulmonary artery aneurysm. We experienced a case of pulmonary artery aneurysm with pulmonary hypertension in a 58 year-old female and observed for 2 years. The aneurysmal size was 5.19 cm initially and inreased to 5.5cm for two years, accompanying by pulmonary hypertension. We report this case of pulmonary artery aneurysm with a brief review of literature.
