A serious complication of a power injector for coronary angiography
Abstract:
Recently several contrast delivery systems for coronary angiography have been introduced to provide adequate artery opacification through small catheters, which are thought to facilitate patient comfort and reduce hemorrhagic/vascular complications. However, the safety profile of a specific system has not been fully examined. In this case report, we present patients who underwent angiography using a contrast delivery system and suffered from massive air embolism necessitating mechanical support. We discuss the potential mechanism and the prevention of this complication.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
