The heart receives its own supply of blood from the coronary arteries. Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood.

Trabeculectomy, also called Filtration Surgery, is a surgical procedure performed for treatment of glaucoma. The treatment involves removing part of the trabecular meshwork and creating a new escape route for the aqueous humor. When successful, it allows the aqueous fluid to drain from the eye into an area underneath the conjunctiva where it is subsequently absorbed by the body's circulatory system or filtered into tears.
In this procedure:
- A conjunctival pocket is created and maybe treated with Mitomycin or other antimetabolites for a few minutes. These drugs are used to prevent scarring of the operation site. Scarring, if occurs, may clog the new drainage canal, and is therefore the major reason the procedure may fail.
- A half thickness flap is then made in the sclera and is dissected all the way to the clear cornea.
- A block of scleral tissue including part of the trabecular meshwork and Schlemm's canal is then removed to make a hole into the anterior chamber of the eye.
- As the iris may plug up this hole from the inside, a piece of the iris maybe removed at this time. This is called iridectomy.
- The scleral flap is then sutured loosely back in place. These sutures can be released gradually during a couple of weeks after surgery. This allows adjustment of the aqueous flow in order to achieve target pressure and to avoid the complication of having a too low intraocular pressure.
- The conjunctiva is sewn back in place to cover the area.
After surgery, aqueous humor drains into a filtering area called a "bleb" under the conjunctiva. Since the surgery is usually performed near the top of the eye, the bleb can easily be concealed behind the upper eyelid.
Guillain-Barre (gee-YAH-buh-RAY) syndrome is a rare disorder in which your body's immune system attacks your nerves. Weakness and tingling in your extremities are usually the first symptoms. These sensations can quickly spread, eventually paralyzing your whole body. In its most severe form Guillain-Barre syndrome is a medical emergency. Most people with the condition must be hospitalized to receive treatment. The exact cause of Guillain-Barre syndrome is unknown. But it is often preceded by an infectious illness such as a respiratory infection or the stomach flu. There's no known cure for Guillain-Barre syndrome, but several treatments can ease symptoms and reduce the duration of the illness. Most people recover from Guillain-Barre syndrome, though some may experience lingering effects from it, such as weakness, numbness or fatigue.
A colonoscope is the special tool used to perform a colonoscopy. It is a thin, flexible, tubular ‘telescope’ with a light and video camera that your doctor carefully guides through your colon in order to see and determine the health of your colon. Watch this animation to learn about the features of the colonoscope, how the colonoscopy procedure is performed and how polyps are removed, and the follow-up care you and your doctor should talk about after your procedure.
Stapling is used to treat prolapsed hemorrhoids. A surgical staple fixes the prolapsed hemorrhoid back into place inside your rectum and cuts off the blood supply so that the tissue will shrink and be reabsorbed. Stapling recovery takes less time and is less painful than recovery from a hemorrhoidectomy.

The essential components of the human cardiovascular system are the heart, blood and blood vessels. It includes the pulmonary circulation, a "loop" through the lungs where blood is oxygenated; and the systemic circulation, a "loop" through the rest of the body to provide oxygenated blood.
Oral sex can be an enjoyable, healthy part of an adult relationship. But there are some things that many people don't know about oral sex. Here are four facts that might surprise you. 1. Oral sex is linked to throat cancer. Cancer? Yes, you can get throat cancer from oral sex, says American Cancer Society Chief Medical Officer Otis Brawley, MD. It's not oral sex, per se, that causes cancer, but the human papillomavirus (HPV), which can be passed from person to person during sex, including oral sex.
Loa loa filariasis (also known as loiasis, loaiasis, Calabar swellings, Fugitive swelling, Tropical swelling and African eyeworm) is a skin and eye disease caused by the nematode worm, loa loa. Humans contract this disease through the bite of a Deer fly or Mango fly (Chrysops spp), the vectors for Loa loa. The adult Loa loa filarial worm migrates throughout the subcutaneous tissues of humans, occasionally crossing into subconjunctival tissues of the eye where it can be easily observed. Loa loa does not normally affect one's vision but can be painful when moving about the eyeball or across the bridge of the nose.The disease can cause red itchy swellings below the skin called "Calabar swellings". The disease is treated with the drug diethylcarbamazine (DEC), and when appropriate, surgical methods may be employed to remove adult worms from the conjunctiva.
They are the leaders of the pack when it comes to minimally invasive surgeries. Laparoscopic and robotic. Different techniques with the same benefits.
"There's significantly less blood loss, it's a quicker procedure, quicker recovery, less scarring, less chance for post operative wound complications or infections," says Dr. Darren Miter, laparoscopic surgeon with Lee Memorial Health System.
In a laparoscopic procedure surgeons operate through a series of poke holes, manually inserting thin cutting tools and a camera to provide magnified vision. It's used in a variety of surgical specialties.
"The vast majority of gallbladder surgeries are performed laparoscopically. A single incision in the belly button, one up under the breastbone and either one or two in the right upper side of the belly. Using long skinny instruments and looking up at a TV monitor, remove the gallbladder that way," says Dr. Miter.
While laparoscopic is a hands-on approach, robotic procedures are surgeon-controlled. Working at a console, surgeons direct the robotic arms, which have super-human capabilities and 3D, hi def vision.
"I mean you have to see it to believe it, that's a great tool to have. You got a very good depth perception. Plus the other thing when you're working with your hands it's more intuitive," says Dr. Nagesh Ravipati, colorectal surgeon with Lee Memorial Health System.
The robotic system performs maneuvers the human hand can't.
"Especially if you have to do any suturing, it is so much simpler with the robots because you can just turn around 360 degrees," says Dr. Ravipati.
Robotic surgery is gaining momentum in precise procedures, including the field of cancer.
"The robot is good when you're going to operate on just one field. For rectal surgery you're in one place, it's docked. It gives you the best 3 dimensional vision," says Dr. Ravipati.
Robotic and laparoscopic. Both cutting edge options, with less cutting.

What are the classifications of burns? Burns are classified as first-, second-, or third-degree, depending on how deep and severe they penetrate the skin's surface. First-degree (superficial) burns. First-degree burns affect only the epidermis, or outer layer of skin. The burn site is red, painful, dry, and with no blisters. Mild sunburn is an example. Long-term tissue damage is rare and usually consists of an increase or decrease in the skin color. Second-degree (partial thickness) burns. Second-degree burns involve the epidermis and part of the dermis layer of skin. The burn site appears red, blistered, and may be swollen and painful. Third-degree (full thickness) burns. Third-degree burns destroy the epidermis and dermis and may go into the subcutaneous tissue. The burn site may appear white or charred Fourth degree burns. Fourth degree burns also damage the underlying bones, muscles, and tendons. There is no sensation in the area since the nerve endings are destroyed.
Vatche, Minassian, MD, MPH, Chief of Urogynecology, and Sarah Cohen, MD, MPH, Director of the Minimally Invasive Gynecologic Surgery Fellowship Program at Brigham and Women’s Hospital, perform a laparoscopic burch colposuspension, a procedure used to correct stress urinary incontinence.
Stress urinary incontinence is one of the most common types of incontinence and is characterized by urinary leakage during physical activities including coughing, sneezing, exercising, lifting, and laughing. As the condition progresses, it can become severe enough to happen with simple acts such as bending and walking. This condition is due to an anatomic weakness of the bladder neck which typically maintains the seal of urine during activity. Stress incontinence can result from a variety of conditions including vaginal childbirth, aging, menopause and obesity. As this is an anatomic condition, primary treatment may involve pelvic floor exercises and/or minimally invasive surgery.

A gastroscopy is a procedure where a thin, flexible tube called an endoscope is used to look inside the oesophagus (gullet), stomach and first part of the small intestine (duodenum). It's also sometimes referred to as an upper gastrointestinal endoscopy. The endoscope has a light and a camera at one end.
