The risks associated with peripheral vascular bypass surgery are related to the progressive atherosclerosis that led to arterial occlusion, including a return of pre-operative symptoms. In patients with advanced PAD, heart attack or heart failure may...
occur. Build up of plaque has also taken place in the patient's arteries of the heart. Restenosis, the continuing build up of plaque, can occur within months to years after surgery if risk factors are not controlled. Other complications may include:
- clot formation in a saphenous vein graft
- failed grafts or blockages in grafts
- reactions to anesthesia
- breathing difficulties
- embolism (clot from the surgical site traveling to vessels in the heart, lungs, or brain)
- changes in blood pressure
- infection of the surgical wound
- nerve injury (including sexual function impairment after aortobifemoral bypass)
- post-operative bleeding
- failure to heal properly
This animation describes percutaneous coronary interventions or PCIs. This procedure actually encompasses a number of diagnostic and therapeutic procedures such as angioplasty or balloon angioplasty. As the video describes, a catheter is inserted into the blood vessels and maneuvered into placed at the diseased portion of the coronary artery. A small balloon is inflated which opens the blocked artery. In most cases a coronary artery stent is left at the site to hold open the coronary artery.
A peripheral vascular bypass, also called a lower extremity bypass, is the surgical rerouting of blood flow around an obstructed artery that supplies blood to the legs and feet. This surgery is performed when the buildup of fatty deposits (plaque) in an artery has blocked the normal flow of blood that carries oxygen and nutrients to the lower extremities. Bypass surgery reroutes blood from above the obstructed portion of an artery to another vessel below the obstruction.
How many open-heart surgeries are performed each year? In 2005 in the United States, these procedures were performed: Valve replacements 106,000 Bypass (cardiac revascularization) 469,000 Heart transplants (performed in 2006) 2,192 Total open-heart procedures 699,000.
