64 Dedektörlü Bilgisayarlı Tomografide Kontrast Madde Enjeksiyonu Sonrası Nonfatal Venöz Hava Embolisi Sıklığı ve Lokalizasyonu

Abstract

During diagnostic and interventional radiological procedures, venous air embolism is seen as a nonfatal event. In this study, it was aimed to determine the frequency and localization of nonfatal venous air embolism in contrast enhanced computed tomography (CT). 1654 contrast-enhanced thorax computed tomography examinations performed in the Radiology Unit of our hospital between January 1, 2019 and December 31, 2019. The localization and size of the detected venous air emboli and from which side the contrast agent was administered were recorded. In this study, iatrogenic venous air embolism was seen in 3.1%. The most common localization is the main pulmonary artery (1.81%) and other localizations in order of frequency are left brachiocephalic vein (0.66%), left subclavian vein (0.36%), right brachiocephalic vein (0.30%), right subclavian vein (0.24%), right ventricle ( 0.18%) and right atrium (0.18%). Looking at the size of the venous air embolism, 2.5% small, 0.50% moderate and 0.12% large air embolism were seen. Radiologists should be aware of the possibility of vascular air embolism after contrast agent injection in CT scanning and should be careful.
