Venous air embolism: Case series of a complication of computed tomography pulmonary angiography (CTPA) in the Emergency Department of Medicine.

CTPA is a procedure that a priori seems innocuous, but it can be a potential cause of death or serious consequences for patients undergoing radiological procedures where the administration of contrast and the use of an injector could be counterproductive. Radiologists and physicians responsible for the patient should be aware of vascular gas embolism after contrast injection in patients undergoing CTPA.
