Arteriosclerosis occurs when the blood vessels that carry oxygen and nutrients from your heart to the rest of your body (arteries) become thick and stiff — sometimes restricting blood flow to your organs and tissues. Healthy arteries are flexible and elastic, but over time, the walls in your arteries can harden, a condition commonly called hardening of the arteries. Atherosclerosis is a specific type of arteriosclerosis, but the terms are sometimes used interchangeably. Atherosclerosis refers to the buildup of fats, cholesterol and other substances in and on your artery walls (plaques), which can restrict blood flow. These plaques can burst, triggering a blood clot. Although atherosclerosis is often considered a heart problem, it can affect arteries anywhere in your body. Atherosclerosis may be preventable and is treatable.
Because the continuous supply of glucose is stopped after birth, the neonate develops hypoglycemia because of insufficient substrate. Stimulation of fetal insulin release by maternal hyperglycemia during labor significantly increases the risk of early hypoglycemia in these infants.
A surgeon creates an arteriovenous fistula by making a connection between an artery (which carries blood away from the heart) and a vein (which carries blood back to the heart). This artificial connection allows the vein to become larger and for the walls of the vein to thicken, a process termed maturation. A mature fistula makes it easier for the vein to be punctured repeatedly for dialysis. Maturation typically takes three to six months to occur, but in rare cases, can take up to a year. This makes advance planning for an arteriovenous fistula important. When a patient is felt to be approximately a year away from requiring dialysis, the patient should be referred for evaluation for possible creation of an arteriovenous fistula.
Electrical injuries can present with a variety of problems, including cardiac or respiratory arrest, coma, blunt trauma, and severe burns of several types. It is important to establish the type of exposure (high or low voltage), duration of contact, and concurrent trauma. Low-voltage AC injury without loss of consciousness and/or arrest These injuries are exposures of less than 1000V and usually occur in the home or office setting. Typically, children with electrical injuries present after biting or chewing on an electrical cord and suffer oral burns. Adults working on home appliances or electrical circuits can also experience these electrical injuries. Low-voltage AC may result in significant injury if there is prolonged, tetanic muscle contraction. Low-voltage AC injury with loss of consciousness and/or arrest In respiratory arrest or ventricular fibrillation that is not witnessed, an electrical exposure may be difficult to diagnose. All unwitnessed arrests should include this possibility in the differential diagnosis. Query EMS personnel, family, and coworkers about this possibility. Inquire if a scream was heard before the patient’s collapse; this may be due to involuntary contraction of chest wall muscles from electrical current. High-voltage AC injury without loss of consciousness and/or arrest Usually high-voltage injuries do not cause loss of consciousness but instead cause devastating thermal burns. In occupational exposures, details of voltage can be obtained from the local power company. High-voltage AC injury with loss of consciousness and/or arrest This is an unusual presentation of high-voltage AC injuries, which do not often cause loss of consciousness. History may need to come from bystanders or EMS personnel. Direct current (DC) injury These injuries typically cause a single muscle contraction that throws the victim away from the source. They are rarely associated with loss of consciousness unless there is severe head trauma, and victims can often provide their own history. Conducted electrical devices Conducted electrical weapons (CEWs) such as tasers are weapons used by law enforcement that deliver high-voltage current that is neither true AC or DC but is most like a series of low-amplitude DC shocks.[16] They can deliver 50,000 V in a 5-second pulse, with an average current of 2.1 mA.[17] Though they have been temporally associated with deaths in the law enforcement setting, conducted electrical devices (CEDs) in healthy volunteers have been shown to be safe without evidence of delayed arrhythmia or cardiac damage as measured by troponin I.[18, 17] One study of their use in 1201 law enforcement incidents showed mostly superficial puncture wounds from the device probes, and significant injuries only from trauma subsequent to shock, not from the device itself. Of 2 deaths in custody, neither was related to CEW exposure.[19]
An excellent video demonstrating how a laparoscopy is performed to evaluate the uterus (note a small fibroid appearing as a bulge in the uterus), fallopian tubes and ovaries. Blue dye is injected into the uterus, entering the fallopian tubes and spilling from the end of the tubes into the abdominal cavity, confirming that both tubes are open
They might not sound very life threatening, but a blood clot that develops in the deep veins of your leg, if left untreated and unable to dissolve of its own volition, may detach and travel to your lungs, causing a pulmonary embolism (or PE). In most cases, a leg blood clot will form due to lengthy periods of travel, for example if you remain immobile in cramped spaces—such as an airplane or bus—with few opportunities to stretch your legs or get up and walk around. Here are ten signs that you may have a dangerous blood clot in your leg
Cholestatic liver disease is a condition that results from an impairment of bile formation or bile flow to the gallbladder and duodenum (first section of the small intestine). ... The effects of cholestasis are profound and widespread, leading to worsening liver disease and systemic illness.
The condition is caused by a blockage in the lymphatic system, part of the immune and circulatory systems. Lymphedema is most commonly caused by lymph node removal or damage due to cancer treatment. The main symptom is swelling in an arm or leg that may be accompanied by pain or discomfort. Exercise, wrapping, massage, and compression can help.

Dr. Ailawadi, M.D., the Chair of Cardiac Surgery at Michigan Medicine, specializes in minimally invasive valve surgery as well as complex cardiac operations. This video shows step by step footage of a Coronary Artery Bypass Graft (CABG) in a complex patient. In this case, CABG was performed through a sternotomy (through the breast bone) using the internal thoracic artery and saphenous leg veins to bypass obstructed coronary arteries. In this video, Dr. Ailawadi will perform a triple vessel bypass (CABG) which has been shown to minimize the risk of future heart attack and help patients live longer in the setting of complex coronary artery disease.
