Why the study?
Both surgical and endovascular revascularization for carotid stenosis carry a risk of brain embolization, prompting a review of the literature on the incidence and detection of these emboli and technologies to reduce them.
This review summarizes the incidence and detection of brain embolization during carotid revascularization and highlights promising technologies to reduce embolization during carotid stenting.
TCD monitoring may detect procedural emboli in carotid revascularization; leaves open impact on outcomes or routine adoption.
Atherosclerotic carotid stenosis is an important cause of stroke. The advent of non-invasive carotid imaging using Doppler ultrasound and computerized tomography angiography has increased the number of patients who are diagnosed with and referred for revascularization of carotid stenosis. Both surgical or endovascular treatments for carotid stenosis carry a risk of brain embolization of plaque debris or in-situ thrombi. These emboli can be detected during these procedures using transcranial Doppler or post-procedures on diffusion magnetic resonance imaging. We review the literature on the incidence and detection of brain embolization during carotid revascularization procedures. We also describe some of the promising technologies to reduce embolization associated with carotid stenting.
