Heart bypass surgery, hysterectomy, joint replacement, cataract surgery and gallbladder surgery are among the top 10 most common surgical procedures performed in the United States, according to Healthgrades. Doctors perform nearly 1.3 million Caesarean sections and over 1 million circumcisions annually in the United States. Angioplasty, stent placement and atherectomy are common procedures that treat coronary artery disease.
As of 2015, approximately 395,000 Americans undergo coronary artery bypass graft surgery every year, making it the most common open-heart surgery. During coronary artery bypass graft surgery, a doctor creates a new route for blood to flow to the heart muscle by connecting a healthy artery to one blocked with plaque. This increases blood flow to the heart and helps to prevent a heart attack, explains Healthgrades.
American doctors perform approximately 720,000 knee replacements and 330,000 hip replacements every year, along with surgical procedures on other joints, such as ankles and shoulders, notes Healthgrades. Joint damage is often the result of an arthritic condition, and individuals receive either portions of or entirely new artificial joints to replace the damaged areas of their existing joints.
Fifty percent of all Americans develop cataracts by age 80, reports Healthgrades, and doctors perform cataract surgery on approximately 3 million individuals every year. This procedure typically occurs on an outpatient basis, and the surgeon replaces a cloudy eye lens with an artificial one that improves visual clarity.
