Summary
A patient developed a new pseudoaneurysm after prior surgery. Prompt re-repair using hypothermic circulatory arrest led to an uneventful recovery, demonstrating successful management of coronary artery pseudoaneurysms.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Medical Imaging
Background:
- Previous composite graft surgery for pseudoaneurysms.
- Recurrence of pseudoaneurysms at new sites, including the left coronary artery.
Purpose of the Study:
- To report a case of recurrent coronary artery pseudoaneurysm after composite graft repair.
- To describe the successful acute re-repair of a ruptured left coronary artery pseudoaneurysm.
Main Methods:
- Computed tomography (CT) and angiography for diagnosis.
- Emergency re-operation with presternotomy and hypothermic circulatory arrest.
Main Results:
- Successful diagnosis of a new left coronary artery pseudoaneurysm.
- Acute re-repair achieved with hypothermic circulatory arrest.
- Resolution of temporary postoperative neurological dysfunction and uneventful recovery.
Conclusions:
- Composite graft repair can be complicated by recurrent pseudoaneurysms.
- Prompt diagnosis and surgical intervention, including hypothermic circulatory arrest, are crucial for managing ruptured coronary artery pseudoaneurysms.
- This case highlights the successful management of complex vascular complications post-cardiac surgery.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

Aneurysm I: Introduction
604
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
