Summary
Mobile carotid plaques are rare and their treatment is debated. This study suggests medical management may be effective for asymptomatic cases, with surgery reserved for significant carotid stenosis.
Area of Science:
- Vascular Surgery
- Neurology
- Diagnostic Imaging
Background:
- Mobile carotid plaques are infrequently reported, posing diagnostic challenges compared to thrombotic lesions.
- The natural history and optimal treatment strategies for mobile carotid plaques remain unclear.
- Current treatment decisions often depend on the perceived embolic potential of the plaque.
Observation:
- Two cases of mobile carotid plaques diagnosed via ultrasound Doppler are presented.
- Case 1: Symptomatic patient with >70% carotid stenosis underwent surgical treatment.
- Case 2: Asymptomatic patient with 30-50% stenosis and distal >70% stenosis received medical management and improved.
Findings:
- Mobile carotid plaques can be managed medically, particularly in neurologically asymptomatic individuals.
- Surgical intervention for mobile carotid plaques should be considered based on the degree of associated carotid stenosis.
- Reported cases, including this series, indicate positive outcomes with medical treatment for asymptomatic mobile plaques.
Implications:
- Mobile carotid plaques alone may not necessitate carotid endarterectomy without further data on their natural history.
- Treatment decisions for mobile carotid plaques should integrate plaque characteristics with the severity of carotid stenosis.
- Further research is needed to establish definitive guidelines for managing mobile carotid plaques.
