This video, created by Nucleus Medical Media, shows a coronary artery bypass graft (CABG) procedure used to combat coronary artery disease. Beginning with a midline sternal incision, the heart is connected to a perfusion machine which will take over the duties of the heart while the surgery takes place. Two different grafts are used to bypass the blocked coronary arteries: the internal thoracic artery from inside the chest wall, and the saphenous vein from the leg. After the procedure, the heart is shocked to restart its beating. A drainage tube is left at the incision site to drain away excess fluid. The animation continues to show two other types of approaches to a coronary artery bypass graft, off-pump bypass surgery and minimally invasive bypass surgery.
This is similar to the procedure performed on former president Bill Clinton and former California governor Arnold Schwarzenegger.

Rubber band ligation is a procedure in which the hemorrhoid is tied off at its base with rubber bands, cutting off the blood flow to the hemorrhoid. This treatment is only for internal hemorrhoids. To do this procedure, a doctor inserts a viewing instrument (anoscope) into the anus. The hemorrhoid is grasped with an instrument, and a device places a rubber band around the base of the hemorrhoid. The hemorrhoid then shrinks and dies and, in about a week, falls off. A scar will form in place of the hemorrhoid, holding nearby veins so they don't bulge into the anal canal. The procedure is done in a doctor's office. You will be asked whether the rubber bands feel too tight. If the bands are extremely painful, a medicine may be injected into the banded hemorrhoids to numb them. After the procedure, you may feel pain and have a sensation of fullness in the lower abdomen. Or you may feel as if you need to have a bowel movement. Treatment is limited to 1 to 2 hemorrhoids at a time if done in the doctor's office. Several hemorrhoids may be treated at one time if the person has general anesthesia. Additional areas may be treated at 4- to 6-week intervals.
Thoracentesis is a procedure used to obtain a sample of fluid from the space around the lungs. Normally, only a thin layer of fluid is present in the area between the lungs and chest wall. However, some conditions can cause a large amount of fluid to accumulate. This collection of fluid is called a pleural effusion.

3D animation depicting the operating room and initial procedure preparing the patient for a laparoscopic hysterectomy. The patient is prepped and draped in the usual fashion and surrounded by the surgeon and surgical assistants. The skin is elevated, an infraumbilical incision is made, a trocar port is inserted through the incision and the abdomen is insufflated. Finally, a laparoscope is inserted into the port to allow for direct visualization of the uterus and the surgery can begin.
