Pulmonary artery catheter occlusion as an indication of pulmonary embolus.
Two patients with respiratory failure had consistently reproducible findings on insertion of flow directed pulmonary artery catheters which led to the subsequent diagnosis of pulmonary embolus. Occlusion of the catheter tip and development of a rising "overwedge" tracing on deflation of the balloon may mean the catheter tip has become embedded in clot. When combined with the inability to obtain...
متن کاملDifferential ventilation in unilateral pulmonary artery occlusion.
A case is reported of complete isolated occlusion of the right pulmonary artery resulting in underperfusion of the right lung; this was confirmed radiographically and at thoracotomy. Bronchospirometry showed that there was a reduction of ventilation to the right lung. When this lung alone was supplied with a carbon dioxide rich mixture there was a shift of ventilation towards the normal pattern...
متن کاملPulmonary artery occlusion by tuberculous mediastinal lymphadenopathy.
Two cases of tuberculous mediastinal lymphadenopathy are presented in which the clinical features mimicked those of pulmonary embolism, causing striking abnormalities on radionuclide scintigraphy. It is concluded that tuberculous mediastinal lymphadenopathy should be included in the differential diagnosis of reduced lung perfusion due to proximal pulmonary artery occlusion.
متن کاملOverestimation of pulmonary artery occlusion pressure in pulmonary hypertension due to partial occlusion.
OBJECTIVE To evaluate partial occlusion in patients with pulmonary hypertension with regard to a) the degree to which it leads to overestimation of pulmonary artery occlusion pressure (Ppao) and b) identification of factors that could enhance its recognition. DESIGN Observational descriptive study. SETTING Medical intensive care unit. PATIENTS Fourteen patients with pulmonary hypertension...
متن کاملPulmonary blood volume in experimental unilateral pulmonary-artery occlusion.
THE behavior of the vascular bed appears to be contradictory. A number of papers indicate that the pulmonary circulation in man shows slight variations in arterial pressure during muscular exercise," after pulmonary resections" or following the occlusion of a main branch of the pulmonary artery." Conversely, other experimental and clinical studies appear to demonstrate that the pulmonary vascul...
