Insights
Aortic dissection, a serious condition affecting the aorta, can present with neurological symptoms. This case highlights successful surgical repair for a patient experiencing stroke-like symptoms due to aortic dissection.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Neurology
Background:
- Aortic dissection is a life-threatening condition involving a tear in the aorta's inner layer.
- Neurological deficits can occur in aortic dissection due to compromised blood flow to the brain.
- Prompt diagnosis and intervention are crucial for favorable outcomes.
Abstract:
A 63-year-old Japanese man with no significant medical or family history was admitted for sudden consciousness disturbance, left hemiparesis and shock. Physical examination showed internal carotid artery asymmetry on palpation and significant differential blood pressure in both upper arms. A thoracic CT scan showed classic aortic dissection from the ascending aorta through the common iliac artery, classic dissection of the left common carotid artery and an intramural haematoma in the right common carotid artery. The patient's consciousness level gradually improved, and he underwent emergency surgery involving aortic rebuilding with a synthetic graft. Subsequently, he had a good clinical course.
