Carotid Artery Surgery In Sickle Cell Disease Patients

Carotid artery surgery in sickle cell disease patients; is the surgical removal procedure of plaque that is built up inside of the carotid artery, in order to restore blood flow to the brain. It serves as a treatment for carotid artery disease and helps in the prevention of stroke in sickle cell disease patients. It is major surgery with several risks and complications.

Carotid artery surgery is carried out when the patient is known to have developed a complication called carotid artery disease, also known as carotid artery stenosis; described as the narrowing of the carotid arteries in the brain of patients with sickle cell disease.

Every human has two carotid arteries, which are located on both sides of the neck; they are major arteries that are responsible for blood supply from the heart to the brain. Carotid artery disease is caused by atherosclerosis; characterized by the hardening of tissues. Atherosclerosis is a buildup of plaque in the carotid artery.

Plaque is characterized as a sticky and waxy deposit of fats, cholesterol, calcium, and fibrous material. Carotid artery disease causes patients with sickle cell disease to have a stroke. The subdivision of carotid artery surgery in patients is Carotid endarterectomy, and Carotid artery angioplasty and stenting.

The procedures that aid the diagnosis of carotid artery disease are; Carotid angiography; it makes images (called an angiogram) of the brain showing the carotid arteries more enlarged. This is a minimally invasive test that requires the catheter placement into the arm of the patient, to inject or transfuse dye into the carotid arteries for easy detection by the carotid angiography.

Carotid ultrasound; is a non-invasive, also painless screening test that examines the carotid arteries and evaluates the level of blood flow through them to the brain. Carotid artery surgery further treats carotid artery disease with the following developed complications; carotid artery stenosis of 60% or more, prior stroke, and prior transient ischemic attack TIA.
