Summary
Painless acute aortic dissection presenting solely with paraplegia is rare. This case highlights the importance of considering aortic dissection in patients with sudden, painless paralysis.
Area of Science:
- Cardiovascular Surgery
- Neurology
- Vascular Medicine
Background:
- Acute aortic dissection (AAD) is a life-threatening condition often associated with severe chest or back pain.
- Paraplegia can occur in AAD due to spinal cord infarction, but typically in patients experiencing significant pain.
Observation:
- A rare case of painless AAD presenting exclusively with sudden-onset paraplegia is reported.
- Magnetic Resonance Imaging (MRI) confirmed extensive aortic dissection with an intramural hematoma as the cause of paraplegia.
- Conservative management focused on strict blood pressure control was initiated.
Findings:
- The patient's aortic dissection was successfully managed conservatively with blood pressure control.
- Despite successful treatment of the dissection, motor function in the lower extremities was not restored.
- This presentation underscores the atypical, painless manifestation of AAD leading to paraplegia.
Implications:
- Aortic dissection should be considered in the differential diagnosis of sudden-onset, painless paraplegia, even without typical pain symptoms.
- Early recognition and appropriate management of AAD are crucial, even in rare, atypical presentations.
- This case emphasizes the potential for severe neurological deficits from AAD without antecedent pain.
