The mechanism by which the pulmonary artery pressure rises in response to hypoxia has never been clearly demonstrated. This problem was reinvestigated in experiments utilizing separate pulmonary and systemic perfusion systems. These vascular beds were perfused in such a fashion that a change in pulmonary artery pressure could only result from changes in vasomotor tone. Alveolar-pulmonary vein hypoxia was usually associated with a slight fall in pulmonary artery pressure. Systemic hypoxia resulted in elevation of pulmonary arterial pressure in 10 of the 12 animals tested with a constant-flow and constant-pulmonary venous pressure. In addition, all animals with systemic desaturation showed an increased venous return. When the "cardiac output" (pump output) was increased to match this return, the elevation in pulmonary artery pressure increased. It was concluded that the pulmonary arterial pressure elevation seen with hypoxia is the result of active pulmonary vasoconstriction coupled with an increased pulmonary blood flow.

We developed a chronic lung fistula that drains only the left lung, allowing for evaluation of injury in a single lung. To remove lymph drainage from the right lung into the caudal mediastinal lymph node, the right lower pulmonary ligament was severed. Pneumatic occluders were placed on the left pulmonary arteries and veins. To ensure that lymph drained from only the left lung, we increased the right pulmonary arterial pressure (RPAP) from 21.2 +/- 0.5 to 36.5 +/- 0.6 mmHg. The left pulmonary arterial pressure (LPAP) was kept at wedge pressure level for 1 h by inflating pneumatic occluders. Lymph flow from the left lung fistula was stable during this occlusion. Six hours after recovery was increased the LPAP from a baseline level of 19.1 +/- 1.0 to 36.4 +/- 0.9 mmHg and the RPAP from 21.2 +/- 0.5 to 38.0 +/- 0.8 mmHg for 2 h by inflating the pneumatic occluders on the left and right pulmonary veins. Lymph flow increased from 5.3 +/- 1.0 to 28.0 +/- 2.9 ml/h. Reflection coefficient was calculated at 0.80 +/- 0.02.

AbstractIn a girl suffering from “Scimitar syndrome”, a rerouting of the scimitar vein was performed at the age of 6 years, but no embolisation of the aberrant systemic vessel was done. She presented with recurring respiratory problems 13 years later. An angiography revealed an invert flow from the aberrant systemic vessel via the right pulmonary artery into the left pulmonary artery. After pneumonectomy, she recovered well.

AbstractMajor abnormalities of pulmonary circulation are uncommon in the patient with pulmonary atresia and intact ventricular septum. Non-confluent pulmonary arteries have only rarely been described in this setting. In this case report, we describe a patient in whom the pulmonary arteries are non-confluent, with the right pulmonary artery supplied through a right-sided arterial duct, and the left pulmonary artery most likely through a fifth aortic arch, thus providing a systemic-to-pulmonary arterial connection. We discuss the various forms of non-confluent pulmonary arteries in the setting of pulmonary atresia and intact ventricular septum.

Pulmonary artery intimal sarcomas are rare and lethal malignant tumors that typically affect larger vessels: the aorta, inferior vena cava, and pulmonary arteries. Since symptoms and imaging of pulmonary arterial intimal sarcomas mimic pulmonary thromboembolism, the differential diagnosis of a patient presenting with chest pain, dyspnea, and filling defect within the pulmonary arteries should include intimal sarcoma. Often right ventricular failure is observed due to pulmonary hypertension caused by the obstructive effect of the tumor and concomitant chronic thromboembolism. We report the case of a 72-year-old African-American male with arterial intimal sarcoma of the left and right pulmonary artery with extension through the right artery into the bronchus and right lung.
