WHAT IS BEATING HEART BYPASS SURGERY?
WHAT IS BEATING HEART BYPASS SURGERY? samer kareem 11,222 Views • 3 years ago

When your arteries cannot supply enough blood to your heart, your doctor may recommend coronary artery bypass graft (CABG) surgery. One of the most common heart surgeries in the United States, CABG surgery restores blood flow to your heart. Approximately every 10 minutes, someone has beating heart or "off-pump" bypass surgery1. Beating heart bypass surgery is — in simple terms — bypass surgery that is performed on your heart while it is beating. Your heart will not be stopped during surgery. You will not need a heart-lung machine. Your heart and lungs will continue to perform during your surgery. Surgeons use a tissue stabilization system to immobilize the area of the heart where they need to work. Beating heart bypass surgery is also called Off Pump Coronary Artery Bypass Surgery (OPCAB). Both OPCAB and conventional on-pump surgery restore blood flow to the heart. However, off-pump bypass surgery has proven to reduce side effects in certain types of patients.

Breast Abscess
Breast Abscess samer kareem 5,415 Views • 3 years ago

Breast abscesses are often linked to mastitis – a condition that causes breast pain and swelling (inflammation), and usually affects women who are breastfeeding. Infections can occur during breastfeeding if bacteria enter your breast tissue, or if the milk ducts (tiny tubes) become blocked. This can cause mastitis which, if not treated, can result in an abscess forming. Women who aren't breastfeeding can also develop mastitis if bacteria enter the milk ducts through a sore or cracked nipple, or a nipple piercing. White blood cells are sent to attack the infection, which causes tissue at the site of the infection to die. This creates a small, hollow area that fills with pus (an abscess).

Hypercalcemia
Hypercalcemia samer kareem 1,238 Views • 3 years ago

Hypercalcemia is a condition in which the calcium level in your blood is above normal. Too much calcium in your blood can weaken your bones, create kidney stones, and interfere with the way your heart and brain works. Hypercalcemia most commonly results from overactive parathyroid glands. These four tiny glands are each about the size of a grain of rice and are located on or near the thyroid gland. Other causes of hypercalcemia include cancer, certain other medical disorders, some medications, and excessive use of calcium and vitamin D supplements. Signs and symptoms of hypercalcemia may range from nonexistent to severe. Treatment depends on the underlying cause.
