“…Perfusion defects seen on ventilation and/or perfusion scanning mimic those seen on PE but may yield false negative results due to rapid resorption of air bubbles. 41 Similarly, both spiral CT and pulmonary angiography may show filling defects if done before the air has been resorbed. Moreover, spiral CT may have an unacceptably high false positive rate as up to 25% of scans may show small (<1 mm), asymptomatic air bubbles.…”

The use of the central venous catheter may be complicated by air embolism when central venous pressure is subatmospheric and the catheter is open to the surrounding air. Paradoxical air embolus occurs when the gas bubbles are able to traverse a right to left shunt, gaining access to the systemic arterial circulation causing ischemic symptoms in end organs. In this article, a case of a patient with an unknown patent foramen ovale through which air entered the arterial circulation resulting in obtundation and stroke after inadvertent manipulation of a Hickman catheter is presented. The physiology, clinical manifestations, and management strategies are also discussed.

“…VQ scan could show VQ mismatch in cases of massive air embolism. The rapid resolution of the perfusion defects (within 24 hours on repeat VQ scan) may help differentiate venous air embolism and other forms of pulmonary thromboembolism [8]. CT chest may show air emboli in central veins, right ventricle, pulmonary artery, or heart.…”

Air embolism is an infrequent but potentially catastrophic complication. It could be a complication of invasive procedures including surgery, central line placement, positive pressure ventilation, trauma, hemodialysis, pacemaker placement, cardiac ablation, and decompression sickness. Usually, it does not cause any hemodynamic complication. In rare cases, it could lodge in the heart and cause cardiac arrest. We present a case of an 82-year-old white female who underwent computed tomography (CT) guided biopsy of right lung pulmonary nodule. When she was turned over after the lung biopsy, she became unresponsive and developed cardiopulmonary arrest. She underwent successful resuscitation and ultimately was intubated. CT chest was performed immediately after resuscitation which showed frothy air dense material in the left atrium and one of the right pulmonary veins suggesting a Broncho venous fistula with air embolism. Although very rare, air embolism could be catastrophic resulting in cardiac arrest. Supportive care including mechanical ventilation, vasopressors, volume resuscitation, and supplemental oxygen is the initial management. Patients with cardiac, neurological, or respiratory complications benefit from hyperbaric oxygen therapy.

The authors encountered a patient with an indwelling central venous catheter who presented with pulmonary edema after the catheter hub was disconnected. Pulmonary arteriography demonstrated diffuse peripheral vasoconstriction, decreased arterial-to-venous transit time, and arterial occlusions. The former two findings allowed the authors to prospectively suggest the diagnosis of pulmonary air embolism.
