When is this procedure indicated?
Obstruction or narrowing of the carotid arteries can cause permanent or transient disorders to:
- sensation (paresthesia);
- speech (aphasia);
Diagnosis can be made from the outside with carotid echo-Doppler, an ultrasound probe.
How is it performed?
The operation is performed through the insertion under local anesthesia of thin cannulas at groin level and allows to remove obstructions in the carotid arteries that carry blood to the brain.
As an alternative to traditional surgery, it is possible to widen the narrowing from the inside through the application of balloons and stents. Because of the risk of embolism that can be caused by detachment of the material that makes up the narrowing, these surgeries are often performed with the use of protective filters that collect and carry the embolized material to the outside, or proximal protection systems with occlusion balloons in the common and external carotid arteries.
Narrowing of the carotid arteries routinely occurs at the level of the neck where the arteries bifurcate.
The length of stay is usually 3 days.
