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 کاملMissile pulmonary embolus secondary to abdominal gunshot wound
Missile pulmonary emboli are rare sequelae of traumatic entry of projectile missiles-generally bullets or bullet fragments-in which access to the systemic venous circulation is established by the missile, making it possible for the missile to migrate to the pulmonary arteries. In the case introduced here, a 24-year-old male presented to the ER with a gunshot wound to the abdomen. In the early c...

We report the clinical case of a 64-year-old female patient, whose anomaly was diagnosed d...
متن کاملLung Changes After Occlusion of Pulmonary Artery Branches by Embolus and by Ligature
The cellular alterations from bland embolism of the lung are reported to be very different from those which follow occlusion by ligation of the pulmonary vessels. Thus, in the normal lung, embolism produces an ischemic, pale zone that may develop no cellular changes or may become congested within a few hours and present small foci of red cell extravasation. The tissues then gradually clear and ...
