This can be particularly concerning in the context of intravenous therapy, where catheters and needles may cause damage to the blood vessels.

Recognizing a thrombus is important because it can lead to more serious complications, including deep vein thrombosis or pulmonary embolism if the clot dislodges and travels to the lungs. Monitoring for signs of complications such as swelling, pain, or changes in circulation is critical in a healthcare setting to manage these risks effectively.
