Which of the following sentences are true for the treatment of carotid stenosis?A. Operative indications are the same both for symptomatic and asymptomatic patientsB. There is a higher risk of stroke after carotid stent implantation compared with open surgical treatmentC. Patients with asymptomatic ICA stenosis above 70% should always be treated with surgeryD. Patients with symptomatic ICA stenosis below 50% should be treated conservatively
Question
Which of the following sentences are true for the treatment of carotid stenosis?A. Operative indications are the same both for symptomatic and asymptomatic patientsB. There is a higher risk of stroke after carotid stent implantation compared with open surgical treatmentC. Patients with asymptomatic ICA stenosis above 70% should always be treated with surgeryD. Patients with symptomatic ICA stenosis below 50% should be treated conservatively
Solution
The following sentences are true for the treatment of carotid stenosis:
B. There is a higher risk of stroke after carotid stent implantation compared with open surgical treatment. This is because carotid stent implantation is a less invasive procedure and therefore carries a higher risk of complications such as stroke.
D. Patients with symptomatic ICA stenosis below 50% should be treated conservatively. This is because the risks of surgery may outweigh the benefits in these patients. Conservative treatment may include lifestyle changes, medication to control risk factors, and regular monitoring of the condition.
The other statements are not generally accepted as true:
A. Operative indications are not the same for symptomatic and asymptomatic patients. The decision to operate often depends on the severity of symptoms and the degree of stenosis.
C. Patients with asymptomatic ICA stenosis above 70% should not always be treated with surgery. The decision to operate should take into account the patient's overall health, the risks of surgery, and the potential benefits of reducing the risk of stroke.
