Typical Clinical Scenarios

An elderly patient on chronic anticoagulation presents emergently with acute chest wall swelling, hypotension, and a rapidly expanding hematoma after a recent sternotomy. Imaging and clinical exam localize active arterial bleeding from the left internal mammary artery requiring operative evacuation and hemostasis in the inpatient setting; an open drainage with placement of a drain may be performed to control bleeding and monitor ongoing output. Typical codes: 039100Z, 03910ZZ
A middle-aged patient develops a contained pseudoaneurysm of the left internal mammary artery identified on CT angiography during evaluation for recurrent chest wall pain weeks after cardiac catheterization. The patient is admitted for a planned percutaneous drainage and decompression of the pseudoaneurysm to relieve mass effect and prevent rupture, often performed under imaging guidance with a percutaneous drain. Typical codes: 039130Z, 03913ZZ
A postoperative patient with signs of infection and persistent seroma at the left internal mammary artery harvest site fails conservative therapy, and a percutaneous endoscopic procedure is performed in the hospital to evacuate infected fluid, irrigate the arterial bed, and place a drainage device to facilitate source control. Typical codes: 039140Z, 03914ZX
