Definition
Meaning

FAQ
Frequently Asked Questions
Yes, it is considered major surgery as it involves opening an artery, often under general anaesthesia, and carries risks such as stroke, heart attack, or bleeding.
Endarterectomy is an open surgical procedure to physically peel out plaque. Angioplasty is a minimally invasive procedure where a balloon is inflated inside the artery to compress the plaque, often followed by placing a stent.
Initial hospital stay is typically 1-3 days. Full recovery, including return to normal activities, can take several weeks, with strenuous activity restricted for about 4-6 weeks.
It is most commonly performed on the carotid arteries in the neck (to prevent stroke) and the femoral arteries in the legs (to prevent limb loss). It is technically possible on other medium-to-large arteries, but suitability depends on the location and extent of the disease.
