6-12 week restricted. The sternum (breast bone) is the vulnerable item after bypass and one shouldn't drive or lift anything >5# for 6 weeks. No heavy lifting for 12 weeks. One can walk and shower within days. Sex is okay when one feels well enough.
Survival advantage. The advantages include relief of chest pain, prevention of heart attack and improving survival. The limitations include risks of surgery, pain and recovery time.
Better long term. For select patients, those with diabetes, left main or 3 vessel disease, depressed left ventricular function the results are dramatic for long term survival, decreased reintervention rates and symptom relief.
Many. Stop angina in some patient groups, prolong survival. Increase coronary blood flow. Follow with cardiac rehab to prevent new or recurrent issues. Limited by patient risk factors, and behavior (smoking, obesity, diabetes) some immediate risk of the surgery for dying, bleeding, infection, stroke but < 2% in general.
See video. In you tube there is a nice video showing the procedure. There are also visual graphics and animations.
Major surgery. It's one of the most commonly performed major operations. Routinely, surgery takes about 4-5 hours; hospitalization last 4-7 days on average. One recovers over 4-8 weeks with full recovery by 4-6 months. No driving for 6 weeks. The purpose is to help folks return to full function with normal life and is successful in the vast majority.
Step by step. Hello leenicole-- coronary artery bypass ad graft surgery is done in a strict step by step procedure involving first obtaining the bypass graft vessels -- which could be veins in the leg or arteries in the arms/chest -- then the sternum (chest bone) is split and forced open to access the heart in full view and the blocked vessel is bypassed -- etc.
It is done. With or without cardio-pulmonary bypass. The core principle is to bypass a blocked coronary artery using vein, mammary artery as conduit or substitute, like cephalic vein or gastro-epiploic artery in extreme circumstances.
Yes. The coronaries are to deliver oxygen and nutrients to the muscle of the heart. When there are blockages in the native arteries a surgeon can open the sternum and take veins from the legs to bypass the blockages by rerouting blood from the aorta past the blockage. This is done under anesthesia in a hospital operating room.
Yes. 1.Sternotomy, 2.Conduit harvest, 3.Full heparinization and institution of cardiopulmonary bypass, 4. With or without induction of cardioplegic arrest, 5. Microsurgical arteriotomies and anastomoses of the end of the conduits to the side of the coronaries distal to the obstruction and to the aorta, 6.Restoration of systolic function, wean off cpb reverse hep., hemostasis, chest tubes, pacing leads, close.
CAD and damaged LV. Patients with either narrowing in all 3 cornary arteries or left main narrowing and a damaged left ventricle live longer with bypass surgery, more than 95 % have improvement in their angina pectoris (chest pain).
You, the patient. Triple vessel disease, left main coronary critical stenosis, selected double or single vessel disease specially if mammary to LAD involved, patients with diabetes.
