Insights
A patient with neurological symptoms had aortic mural thrombi, which were successfully removed. This surgical intervention resolved the cerebrovascular symptoms, leading to a full recovery.
Area of Science:
- Cardiovascular Medicine
- Neurology
- Vascular Surgery
Background:
- Mural thrombi in the ascending aorta can lead to embolic events, causing cerebrovascular symptoms.
- Atherosclerosis is a common underlying condition contributing to aortic pathology.
Observation:
- A 59-year-old male presented with neurological dysfunction attributed to a mobile mural mass in the ascending aorta.
- Echocardiography and 3D CT confirmed the presence of the aortic mural mass.
- No coagulopathy was identified as a contributing factor.
Findings:
- Surgical removal of the aortic mural masses was performed under cardiopulmonary bypass.
- Pathological examination revealed the masses to be organizing thrombi originating from an atherosclerotic aortic wall.
- The patient experienced an uneventful postoperative recovery.
Implications:
- Surgical resection of aortic mural thrombi is an effective treatment for preventing recurrent cerebrovascular events.
- Early diagnosis and intervention can significantly improve patient outcomes in cases of aortic thrombus.
- This case highlights the importance of considering aortic pathology in patients with unexplained neurological symptoms.
Abstract:
A 59-year-old man was transferred to our hospital because of mural thrombus in the ascending aorta. He had suffered some neurological dysfunctions such as transient dysorientation. Electrocardiogram showed normal sinus rhythm without premature beats. Trans-thoracic echocardiogram and three-dimensional CT showed a mobile mural mass sticking to the ascending aortic wall. No coagulopathy was detected in the patient. The mural masses were thought to be a possible cause of the repeated cerebro-vascular symptoms. Under cardiopulmonary bypass and cardiac arrest, the masses were removed including the mass sticking to the aortic wall. Postoperative pathological findings showed the masses were organizing thrombi that had originated from the atherosclerotic aortic wall. Postoperative course was uneventful, and the patient was doing well one year after the operation without neurological dysfunction.
