OBJECTIVE: To assess the value of parameters derived from arterial blood gas tests in the diagnosis of pulmonary embolism. METHOD: We measured alveolar-arterial partial pressure of oxygen [P(A-a)O2] gradient, PaO2 and arterial partial pressure of carbon diaxide (PaCO2) in 773 consecutive patients with suspected pulmonary embolism who were enrolled in the Prospective Investigative Study of Acute...

conclusion ped software of dual-source ct combined with perfusion imaging can significantly improve the detection rate of peripheral pulmonary embolism. results ctpa images revealed 50 (7.81%) segmental and 56 (4.38%) sub-segmental pulmonary embolisms, while the ped images showed 68 (10.63%) segmental and 94 (7.34%) sub-segmental pulmonary embolisms. thus, the detection rate on ped images for p...

BACKGROUND Embolism with gas, thrombus, fat, amniotic fluid, or particulate matter may occur suddenly and unexpectedly during anaesthesia, posing a diagnostic and management problem for the anaesthetist. OBJECTIVES To examine the role of a previously described core algorithm "COVER ABCD-A SWIFT CHECK" supplemented by a specific sub-algorithm for embolism, in the management of embolism occurri...

Coronary air embolism remains a serious complication of cardiac catheterization despite careful prevention. The complications of coronary air embolism range from clinically insignificant events to acute coronary syndrome, cardiogenic shock, and death. We report here a case of multiple air emboli in both left coronary arteries, complicated by cardiogenic shock and ventricular fibrillation in a 4...

A pulmonary embolus clogs the artery that provides blood supply to a part of the lung. The embolus not only prevents the exchange of oxygen and carbon dioxide but also decreases blood supply to the lung tissue itself, potentially causing the tissue to die (infarct). A 52-year-old man presented with syncope and anxiety. He had sinus tachycardia and dilated right ventricle with trabeculations. A ...

A 54 yr old man experienced weakness in his legs, ataxia and subsequent urinary retention after a percutaneous fine-needle aspiration of a tumor in the right lower lobe. Clinical neurological examination and electroencephalography revealed signs of a brain stem lesion, probably due to an air embolism to the basilar artery. The symptoms and signs gradually disappeared prior to, as well as after,...

Radiologist Saurabh “Harry” Jha still recalls the first time he was on call for radiology in the United States. He received simultaneous emergency requests for a head computed tomography (CT) and chest CT, both in the same patient, to rule out stroke and pulmonary embolism. The indication for the examinations was the same: syncopal episode. Jha was flabbergasted. “I thought to myself, there is ...
