          Abstract

          A pulmonary artery aneurysm is an uncommon anomaly. The clinical manifestations are mostly nonspecific, and management is controversial. We report a case of a 67-year-old woman with a main pulmonary artery aneurysm who did not take surgical intervention. Subsequently, there was no increase in size for 3 years.

          Progressive dilatation of the main pulmonary artery is a characteristic of pulmonary arterial hypertension and is not related to changes in pressure.

          Bart Boerrigter, Gert-Jan Mauritz, J. Marcus … (2010)
          Pulmonary artery (PA) dilatation is one of the consequences of pulmonary arterial hypertension (PAH) and is used for noninvasive detection. However, it is unclear how the size of the PA behaves over time and whether it is related to pressure changes. The aim of this study was to evaluate PA size during follow-up in treated patients with PAH and whether it reflects pulmonary vascular hemodynamics. Fifty-one patients with PAH who underwent at least two right-sided heart catheterizations (RHCs) together with cardiac MRI (CMR) were included in this study. Another 18 patients who had normal pressure at RHC were included for comparison at baseline. From RHC, we derived PA pressures and cardiac output. From the CMR images we derived PA diameter (PAD) and the ratio of the PAD and ascending aorta diameter. The PAD was significantly larger in patients with PAH than in patients without PAH (P 1 had a positive predictive value of 92% for PAH. Mean follow-up time was 942 days, and there was a significant dilatation during this period (P < .001). The change of the PAD did not correlate with the changes in pressure or cardiac output. A moderate correlation with follow-up time was found (r = 0.56; P < .001). A dilatated PA is useful for identifying patients with PAH. However, during patient follow-up, progressive dilatation of the PA is independent of the change in PA pressure and cardiac output and might become independent from hemodynamics.

            Congenital and acquired pulmonary artery anomalies in the adult: radiologic overview.

            Eva Castañer, Xavier Gallardo, Jordi Rimola … (2015)
            Various congenital and acquired anomalies may affect the pulmonary arteries in adult patients. Congenital anomalies (proximal interruption, anomalous origin of the left pulmonary artery [pulmonary artery sling], and idiopathic dilatation of the pulmonary trunk) are usually found incidentally at chest radiography or computed tomography (CT). Acquired anomalies include diffuse or focal enlargement of the arteries because of pulmonary hypertension, aneurysm, and intravascular pulmonary metastasis; decreased arterial diameter because of bronchial carcinoma, mediastinal fibrosis, and Takayasu arteritis; and intraluminal filling defects due to pulmonary thromboembolism and pulmonary artery sarcoma. An awareness of the radiologic manifestations of the disease entities and potential pulmonary artery complications secondary to infection or vasculitis may enable an early diagnosis. CT angiography is becoming the standard method for evaluating patients in whom the presence of pulmonary embolism is suspected. CT assessment of the extent of heart effects in patients with pulmonary hypertension and pulmonary embolism is particularly important because such effects largely determine the prognosis.

              Pulmonary artery aneurysm: review and case report.

              M D Botney, Adrian Feijoo, J Mateo … (1995)
              Aneurysms involving the main pulmonary artery and its branches are rare. Clinical experience is limited and current knowledge is mainly derived from autopsy findings. This case report describes a patient with a pulmonary artery aneurysm associated with a previous, partially corrected stenotic pulmonary valve. The patient presented with symptoms suggestive of aneurysm dissection three decades after commissurotomy. The diagnostic approach and therapeutic intervention are emphasized with a review of the literature.
