Spontaneous Closure of a Coronary Artery Bypass Graft Pseudoaneurysm Embedded in a Mediastinal Hematoma

Area of Science:

• Cardiovascular Surgery
• Vascular Surgery
• Medical Imaging

Background:

• Coronary artery bypass graft (CABG) pseudoaneurysms are infrequent but critical complications.
• These pseudoaneurysms pose risks of rupture and hemodynamic instability.
• Early recognition is vital for appropriate patient management.

Observation:

• A patient with recent CABG presented with acute dyspnea and a large pleural effusion.
• Imaging identified a saphenous vein graft pseudoaneurysm within a mediastinal hematoma.
• The pseudoaneurysm demonstrated spontaneous closure over four weeks.

Findings:

• The case illustrates an atypical acute presentation of a CABG pseudoaneurysm.
• Spontaneous resolution of a saphenous vein graft pseudoaneurysm was observed.
• A multidisciplinary approach was employed for management.

Implications:

• Highlights the importance of considering CABG pseudoaneurysms in the differential diagnosis for relevant patients.
• Demonstrates a rare instance of spontaneous pseudoaneurysm closure, impacting management strategies.
• Emphasizes the value of a collaborative, multidisciplinary approach in managing complex cardiovascular surgical complications.
