Removing an Embolized Peripheral Intravenous Catheter from the Left Caudal Lung Lobe of a Dog via Intercostal Thoracotomy

An 8-month-old Standard Poodle was referred to a surgical specialist for suspected peripheral intravenous catheter (PIVC) embolism originating from the right cephalic vein. Upon removing the 20-gauge PIVC, the tip appeared to be 2 cm shorter. Radiographs were obtained for the localization of the PIVC embolism, but no abnormalities were seen. A computed tomography scan of the whole body was performed. PIVC embolism was observed due to a difference in Hounsfield units between the catheter tip and the surrounding lung parenchyma in the ventral aspect of the left caudal lung lobe. A left lateral thoracotomy in the seventh intercostal space was then performed, leading to the successful retrieval of the catheter tip while allowing the lung lobe to be spared. This case report describes a PIVC embolism migrating to the lung parenchyma and its successful surgical removal.
