Painless dissection of the thoracic aorta
The American Journal of Emergency Medicine
|July 1, 1986
Summary
A rare case of bilateral lower extremity paralysis preceding thoracic aortic dissection is presented. This unusual presentation highlights the diverse and sometimes subtle initial symptoms of aortic dissection.
Area of Science:
- Cardiology
- Neurology
- Vascular Surgery
Background:
- Aortic dissection is a life-threatening condition often presenting with severe chest or back pain.
- Neurological deficits can occur in aortic dissection due to compromised blood flow to the brain or spinal cord.
Observation:
- A 64-year-old male presented with a two-week history of intermittent, bilateral lower extremity paralysis.
- The patient denied any associated chest, abdominal, or back pain, making the initial diagnosis challenging.
Findings:
- The patient ultimately died from a thoracic aortic dissection.
- This case underscores that aortic dissection can manifest with atypical neurological symptoms, such as isolated limb paralysis.
Implications:
- Early recognition of subtle or atypical symptoms is crucial for timely diagnosis and management of aortic dissection.
- This case highlights the importance of considering vascular emergencies in the differential diagnosis of new-onset neurological deficits, even without classic pain presentation.
