CONGENITAL stenosis of the pulmonary artery branches is an anomaly characterized by narrowed segments of one or more of the main or peripheral branches of the pulmonary artery. Such conditions lhave been variously labeled pulmonary coaretation,' peripheral pulmonary stenosis,2 and multiple peripheral stenoses 3 of the pulmonary artery. Several cases of this anomaly have appeared in the literatu...

A 63-year-old female presented with abnormal lung shadows but had, apart from this, few symptoms. Computed tomography (CT) revealed multiple nodules and blockage of the pulmonary artery. She was immediately diagnosed with pulmonary artery sarcoma based on a careful differential diagnosis and underwent surgery. Her tumor was pathologically diagnosed as leiomyosarcoma (i.e. intimal sarcoma). Pulm...

A 58-year-old woman was admitted to our department for evaluating an abnormal blood flow in the main pulmonary artery by transthoracic echocardiography. Coronary angiography revealed the presence of fistulas originating from the left anterior descending artery and also the right coronary artery to the main pulmonary artery. Under cardiopulmonary bypass, both fistulas were ligated near the origi...

BACKGROUND Pressure and waveform at the catheter tip are continuously monitored during catheterization of pulmonary artery to ensure accurate catheter placement. We present a case in which pulmonary venous blood was unexpectedly collected from the pulmonary artery catheter despite pulmonary artery pressure and waveform detection at the catheter tip, and describe the measures taken to correct th...

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...

An adult case of pulmonary resection for repeated infections in a supernumerary tracheal bronchus combined with a pulmonary artery sling is reported. A 33-year-old woman with a pulmonary artery sling was referred for recurrent lung infections. Chest computed tomography showed the left pulmonary artery arising from the right pulmonary artery and coursing posterior to the trachea. The lung parenc...

A 46-year old female patient was admitted after a 5-m height fall. Contrast-enhanced CT scan discovered dissection of the right pulmonary artery (Figs 1 and 2) as well as rib fractures, pneumo-/ haemothorax, pulmonary contusions and pneumomedistinum. The dissection was confirmed by another CT scan 6 days later. The course was nonoperatively and uneventful. Figure 1: CT scan revealed dissection ...

Recent years have seen the place of the pulmonary artery catheter in intensive care increasingly challenged, with one recent study reporting no difference in outcome in patients treated with or without a pulmonary artery catheter. However, this study has several methodological flaws and, although pulmonary artery catheterization should not be performed routinely on all patients, when used corre...
