Hydrothorax Due to Extravasation of Intravenous Contrast after Power Injection through Right Subclavian Catheter

摘要

We report a case of hydrothorax after receiving intravenous (IV) contrast material by power injector through right subclavian central venous catheter (CVC) line. A 38-year-old woman presented to the local emergency department with hypotension after a pedestrian accident. After resuscitation, CVC was inserted into her right subclavian vein and fluid was administered well before computed tomography (CT) enhancement. Contrast-enhanced CT scan showed a large amount of extravasation of contrast material and fluid collection in the thoracic and pericardial cavities which was not shown in non-enhanced CT scan. During operation, vascular perforation was found in right subclavian vein. This case highlights that emergency physicians must keep in mind the possibility of vessel injury after CVC insertion and contrast material is preferably injected via peripheral IV access.
