Pulmonary Perfusion Using Intrabronchial Capnography in Pulmonary Artery Stenosis

Pulmonary artery stenosis.

SINCE the description by Mbller' in 1953 of stenosis of peripheral pulmonary arteries, this congenital lesion has been recognized with increasing frequency. The lesion is of interest both from a clinical and physiologic standpoint. From the latter standpoint, there is sufficient documentation to warrant the inclusion of this congenital anomaly as one of the causes of right ventricular hypertens...

Acquired pulmonary stenosis and pulmonary artery compression.

Evaluation of effect of lung resection on lobar ventilation and perfusion using intrabronchial capnography.

Intrabronchial capnography was applied in 11 lung cancer patients to investigate the effects of lobectomy on regional lung function. Spirometry and intrabronchial capnography were performed before surgery (PRE), and during the early (POST1,19 +/- 5 POD) and late (POST2, 184 +/- 98 POD) postoperative periods. End-tidal carbon dioxide concentration (EtCO2) and Smidt's velocity profile index (V-in...

[Dilatation of the pulmonary artery in pulmonary stenosis].

Dilatation of the pulmonary artery occurs frequently in cases of valvular pulmonary stenosis and is often called "poststenotic." We determined the diameter of the pulmonary artery angiocardio-graphically and compared this with the data obtained by heart catheterization in cases of pulmonary stenosis and of idiopathic dilatation of the pulmonary artery. Features are presented which constitute ar...

Peripheral pulmonary artery stenosis in three cats

Case 1 involved a 4-month-old intact male Somali cat in which peripheral pulmonary artery stenosis (PPS) was recognized after a cardiac murmur remained following patent ductus arteriosus ligation. Case 2, which involved a 1-year-old neutered male Norwegian Forest cat, and Case 3, which involved a 6-month-old intact female American Curl cat, were referred, because of cardiac murmurs. Grades III ...
