A few words of thanks would be greatly appreciated.

Bypass surgery - Definition


Bypass surgery is a surgical procedure used to treat blocked arteries that are holding up the blood circulation. This procedure consists of bypassing a defective blood vessel by replacing it with a synthetic tube or another part of a blood vessel that has been removed from the patient, in order to reestablish an optimal circulation by reconnecting the blood vessel before and after the blocked section. Common practice in the 60s, bypass surgery is categorized into several different types of procedure, all classified in terms of their location: coronary artery bypass for the heart, femoral bypass for the lower limbs, carotid bypass surgery for the neck arteries, and so on. This technique is used in cases of vascular stenoses (obstructions), by means of angioplasty via a small inflated balloon inserted into the artery to widen it.
