Insights
A rare case of a giant coronary artery aneurysm completely occluded by a thrombus was successfully treated. Early anticoagulation therapy followed by surgical resection proved effective for this life-threatening vascular disorder.
Area of Science:
- Cardiology
- Vascular Surgery
- Interventional Cardiology
Background:
- Coronary artery aneurysms are uncommon and potentially life-threatening vascular disorders.
- Giant coronary artery aneurysms, especially those completely occluded by thrombus, present unique management challenges.
Observation:
- A 52-year-old male presented with a 50-mm giant right coronary artery aneurysm completely occluded by a thrombus.
- The patient was asymptomatic with stable hemodynamics upon hospital admission.
Findings:
- Initial anticoagulation therapy with heparin led to thrombus dissolution and visualization of the distal coronary artery.
- Successful surgical management involved coronary artery bypass grafting, vessel ligation, and aneurysm resection.
Implications:
- This case highlights the successful combined approach of early anticoagulation and surgical resection for a completely occluded giant coronary artery aneurysm.
- The findings suggest that prompt medical and surgical intervention can effectively manage this rare and dangerous condition.
Abstract:
A coronary artery aneurysm is an uncommon vascular disorder, and it can be a life-threatening disease when associated with rupture or an embolism. A 52-year-old man was found to have a 50-mm coronary artery aneurysm at the right coronary artery, and the aneurysm was completely occluded by a thrombus. He had no symptoms after arriving at our hospital, and his hemodynamics was stable. Therefore, initially, we administered anticoagulation therapy involving heparin. After therapy, the distal coronary artery was detected when the thrombus dissolved, and elective surgery was planned. Coronary artery bypass grafting, ligation of the inflow and outflow vessels, and resection of the aneurysm were performed. Early anticoagulation therapy and surgical aneurysm resection were effective for treating the completely occluded coronary artery aneurysm. We herein report this rare case of a giant coronary artery aneurysm occluded completely by a thrombus and treated successfully by anticoagulation therapy and surgical aneurysm resection.

Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...
