1/6. Fatal air embolism during thoracotomy for gunshot injury to the lung. Report of a case.Fatal coronary air embolism occurred during thoracotomy in a patient with a gunshot wound involving the hilum of the right lung. embolism was observed during a second period of failure of heart action. Evidently, air entered the pulmonary veins from the bronchus, which was receiving positive-pressure ventilation. The literature contains reports of only 3 similar cases, but we suspect that air embolism may be responsible for death and morbidity in additional cases in which accidental or iatrogenic lung trauma has produced a pathway between the bronchial tree and the pulmonary veins.- - - - - - - - - - ranking = 1keywords = positive-pressure (Clic here for more details about this article) |
2/6. Massive air embolism in a neonate with respiratory distress.The occurrence of massive air embolism in a neonate during treatment with intermittent positive-pressure respiration and positive end expiratory pressure is reported as a note of caution. It is possible that this complication may indeed be more common. Careful post-mortem examinations (including radiological examinations) are advocated in order that the true incidence of this devastating event shall be known.- - - - - - - - - - ranking = 1keywords = positive-pressure (Clic here for more details about this article) |
3/6. Computed tomography of fatal cerebral air embolism following percutaneous aspiration biopsy of the lung.air embolism complicated a thin needle aspiration performed on a patient with adult respiratory distress syndrome and on positive-pressure ventilation. Computed tomography obtained 30 h following the event demonstrated a considerable quantity of intravascular air within the cranium. Positive-pressure ventilation should be considered a relative contraindication for thin needle lung aspiration.- - - - - - - - - - ranking = 1keywords = positive-pressure (Clic here for more details about this article) |
4/6. Fatal air embolism to the right side of the heart during pneumonectomy for carcinoma. Result of broncho-azygous vein communication and positive-pressure ventilation.A 59-year-old white man had an extensive bronchogenic carcinoma of the right upper lobe. During the course of pneumonectomy, the patient died unexpectedly. At autopsy, massive right-sided air embolism was evident, associated with broncho-azygous vein communication. The cause of the air embolism and subsequent death was almost certainly related to positive-pressure ventilation, allowing entry of air into the systemic venous system through the broncho-azygous vein communication. Because of the clinical implications of this problem, the case is reported, and suggestions for management are offered.- - - - - - - - - - ranking = 5keywords = positive-pressure (Clic here for more details about this article) |
5/6. Pulmonary vascular air embolism in hyaline membrane disease.Pulmonary vascular air embolism is a rare, fatal complication of positive-pressure ventilation in hyaline membrane disease. Sudden deterioration of an infant on respiratory therapy should alert the clinician and radiologist to the possibility of this entity. A case history with typical radiographic findings is presented.- - - - - - - - - - ranking = 1keywords = positive-pressure (Clic here for more details about this article) |
6/6. Pulmonary hemorrhage and air embolism complicating transbronchial biopsy in pulmonary amyloidosis.We describe a fatal complication of transbronchial biopsy in a patient with pulmonary parenchymal amyloidosis. hemorrhage after biopsy required intubation and positive-pressure ventilation that resulted in massive arterial air embolism. Postmortem findings suggested that the bleeding and air embolism were related to persistent patency of biopsied blood vessels infiltrated with amyloid. patients with pulmonary amyloidosis may be at increased risk of major complications after transbronchial biopsy.- - - - - - - - - - ranking = 1keywords = positive-pressure (Clic here for more details about this article) |
