valtimosiirteitä

Valtimosiirteitä, also known as arterial grafts or bypass surgery, refers to a surgical procedure used to reroute blood flow around a narrowed or blocked artery. This is typically done when an artery is so constricted or occluded that it significantly impedes blood circulation to vital organs or limbs. The most common reasons for this condition are atherosclerosis, a buildup of plaque within the arteries, and injury.

During a valtimonsiirre, a surgeon takes a healthy blood vessel, usually a vein from another part of the body (like the leg) or a synthetic tube, and connects it to the artery above and below the blockage. This creates a new pathway for blood to flow, bypassing the obstructed section. The goal is to restore adequate blood supply to the affected area, thereby relieving symptoms and preventing further damage.

The procedure is most frequently performed on the coronary arteries supplying the heart muscle, a procedure commonly known as coronary artery bypass grafting (CABG). It is also used for arteries in the legs to treat peripheral artery disease, and for arteries in the brain or neck. Recovery time and outcomes vary depending on the location and extent of the blockage, the patient's overall health, and the specific type of graft used. Valtimonsiirteitä is a major surgical intervention, and like all surgeries, it carries inherent risks.
