Acquired Pulmonary Stenosis

چکیده
Acquired pulmonary stenosis refers to narrowing of the right ventricular outflow tract or main pulmonary artery which has developed after birth. It may arise from external pressure or from an intrinsic pathological process, and is generally regarded as a rare condition because few cases have been reported. Our experience, however, suggests that it is probably not as rare as previously believed and can frequently be diagnosed during life. In this paper we review the clinical and radiological features of 13 patients with acquired pulmonary stenosis. Nine were investigated during the past 12 years at the Middlesex Hospital, 3 were seen by Dr. Celia Oakley at the Hammersmith Hospital, and 1 by Mr. W. P. Cleland at King's College Hospital. Acquired pulmonary stenosis produced by aneurysms of the sinuses of Valsalva and aneurysms of the interventricular septum as well as the malignant carcinoid syndrome have not been discussed, since they are considered to be beyond the scope of this paper. Inflammatory lesions referred to by Babcock, Judge, and Bookstein (1962) and listed in Table I as possible causes are also omitted from our discussion because we have not had the opportunity of investigating such a case.

Acquired pulmonary stenosis due to pleomorphic adenocarcinoma.
Acquired pulmonary stenosis was diagnosed in a 53 year old woman presenting with the unusual feature of an oral murmur. Mediastinotomy showed extensive malignant tissue surrounding the pulmonary artery, although a mediastinal mass was not evident on chest radiographs. Histological examination confirmed a pleomorphic adenocarcinoma, which has not previously been reported as causing acquired pulm...
متن کاملPersistent Oxygen Requirement beyond Prematurity: A Case of Acquired Pulmonary Vein Stenosis
Acquired pulmonary vein stenosis is a rare cardiac defect and diagnosis can often be challenging, as many cases present with refractory or prolonged oxygen requirement over the expected course. Comorbid conditions can cloud this diagnosis further. Prognosis is poor for most patients. We present a case of idiopathic acquired pulmonary vein stenosis and discuss diagnostics, treatment options, and...

Background: The Ross procedure has been known as a good method for aortic valve replacement. Pulmonary allograft postoperative stenosis subsequent to the Ross procedure has been noted as an important disadvantage of this technique, although risk factors related to this complication are not clearly recognized. In this study we evaluate the risk factors of pulmonary allograft stenosis after Ross ...
