Insights
A mobile plaque in the descending aorta, initially suspected after myocardial infarction, was diagnosed as mural thrombosis. Thoracic endovascular aortic repair (TEVAR) successfully treated the condition without complications.
Area of Science:
- Cardiovascular Medicine
- Vascular Surgery
- Diagnostic Imaging
Background:
- A 43-year-old male with a history of myocardial infarction presented with a suspicious lesion on the descending aorta.
- Initial computed tomography (CT) suggested a mobile plaque, prompting further investigation.
Purpose of the Study:
- To diagnose and manage a suspected aortic lesion in a patient with recent myocardial infarction.
- To evaluate the efficacy of thoracic endovascular aortic repair (TEVAR) for intra-aortic thrombus.
Main Methods:
- Utilized enhanced CT, MRI, and PET imaging to characterize the aortic lesion.
- Diagnosed mural thrombosis based on imaging findings, excluding embolization or metastatic tumor.
- Performed thoracic endovascular aortic repair (TEVAR) to compress the intra-aortic thrombus.
Main Results:
- The lesion was diagnosed as mural thrombosis, with no signs of embolization or metastatic disease.
- TEVAR was performed successfully, compressing the thrombus without immediate complications.
- The patient experienced a good clinical course with no thromboembolic events for two years post-procedure.
Conclusions:
- Mural thrombosis of the descending aorta can be managed effectively with TEVAR.
- TEVAR offers a safe and successful treatment option for intra-aortic thrombus, preventing thromboembolic complications.
- Close imaging follow-up is crucial for patients with aortic pathologies post-myocardial infarction.
Abstract:
A 43-year-old male patient was admitted to our hospital with chest oppression and received percutaneous coronary intervention with a diagnosis of myocardial infarction. Two months after the event, he was referred to our department because the enhanced computed tomography (CT) image revealed a low-density area on the descending aorta, which was suspicious of a mobile plaque. He had no symptoms and there were no other signs suggesting embolization or metastatic tumor in CT image. Enhanced magnetic resonance imaging (MRI) or positron emission tomography (PET) image revealed no enhancement in the lesion and we diagnosed it as mural thrombosis on the descending aorta. We performed thoracic endovascular aortic repair( TEVAR) to compress the intra-aortic thrombus. He had no complication such as thromboembolism in the procedure and also had a good course for two years after the procedure.
