心臟搭橋手術一問???

樓上講個隻, 俗稱通波仔, 唔係搭橋.
搭橋 = [Coronary artery bypass surgery]
http://en.wikipedia.org/wiki/Coronary_artery_bypass_surgery
Coronary artery bypass surgery, also coronary artery bypass graft surgery, and colloquially heart bypass or bypass surgery is a surgical procedure performed to relieve angina and reduce the risk of death from coronary artery disease. Arteries or veins from elsewhere in the patient's body are grafted to the coronary arteries to bypass atherosclerotic narrowings and improve the blood supply to the coronary circulation supplying the myocardium (heart muscle). This surgery is usually performed with the heart stopped, necessitating the usage of cardiopulmonary bypass; techniques are available to perform CABG on a beating heart, so-called "off-pump" surgery.

血管再成形術（Angioplasty），又名血管成形術、血管擴張手術，泛指為血管進行擴張的醫學手術，通常用以治療動脈硬化。目前最廣泛進行的血管再成形術，為針對心臟冠狀動脈的冠狀動脈再成形術。
心血管疾病的治療須視乎每一個病人的徵狀，但有效的治療包括以上提及的防止性生活方式。藥物如抗高血壓藥、阿司匹林及他汀等降膽固醇藥物都有幫助。[4]在某些情況下，冠心臟動脈搭橋手術或血管成形術可以保證重開、修補或更換受損的血管。
Angioplasty is the technique of mechanically widening a narrowed or totally obstructed blood vessel; typically as a result of atherosclerosis. Tightly folded balloons are passed into the narrowed locations and then inflated to a fixed size using water pressures some 75 to 500 times normal blood pressure (6 to 20 atmospheres)".
The word is composed of the medical combining forms of the Greek words aggeos meaning "vessel" and plasts meaning "formed" or "moulded". Angioplasty has come to include all manner of vascular interventions typically performed in a minimally invasive or percutaneous method.
Treatment of cardiovascular disease depends on the specific form of the disease in each patient, but effective treatment always includes preventive lifestyle changes discussed above. Medications, such as blood pressure reducing medications, aspirin and the statin cholesterol-lowering drugs may be helpful. In some circumstances, surgery or angioplasty may be warranted to reopen, repair, or replace damaged blood vessels.
