Typical Clinical Scenarios

An elderly patient on long-term anticoagulation presents to the emergency department with sudden onset swelling and pulsatile hematoma above the left clavicle after a difficult left subclavian central line placement; imaging confirms an expanding arterial pseudoaneurysm with active extravasation. The patient is admitted for urgent vascular control and evacuation of the collection to stop bleeding and restore perfusion; an open surgical drainage and hematoma evacuation is performed to control hemorrhage. Typical codes: 039400Z, 03940ZZ
A middle-aged patient with bacteremia and persistent fever is found to have a small mycotic focus and thrombus within the left subclavian artery on CT angiography; the team admits the patient for source control and diagnostic sampling. A percutaneous drainage with aspiration of infected material and collection of specimens for culture is performed to guide antimicrobial therapy and remove infected fluid. Typical codes: 039430Z, 03943ZX
A hospitalized post-operative oncology patient develops a loculated infected fluid collection compressing the left subclavian artery identified on ultrasound after prior central access; conservative measures fail and interventional radiology performs a percutaneous endoscopic drainage to evacuate the collection and place a drainage device for ongoing management. Typical codes: 039440Z, 03944ZZ
