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.

We studied the incidence of spontaneous infarct related artery recanalization and it's effect on LV function in 120 patients with acute myocardial infarction by angiography within 1 month after onset of acute MI between Nov. 1983 to Sep. 1988. The total occlusion rate of the infarct related artery in 34 cases catheterized from 1st day to 7th day was 55.8%, that of 33 cases from 8th day to 14th day 51.5%, that of 32 cases from 15th day to 21th day 40.7% and that of 21 cases from 21th day to 30th day was 47.7%. These results suggest that spontaneous recanalization of infarct related artery has mainly occurred within 24 hours after acute MI. LV ejection fraction among those patients who showed spontaneous recanalization(n=59) was not significantly superior to those with persistent occlusion of the infarct related artery. Both anterior and inferior MI patients showed no difference in LV function as regard to whether they showed recanalization or persistent occlusion. Although early spontaneous reperfusion of the infarct related artery is not uncommon in acute MI, LV function was not influnced by the spontaneous recanalization at least until 1 month after MI.
