Renal Artery Aneurysm Repair
Renal Artery Aneurysm Repair samer kareem 7,354 Views • 2 years ago

Indications for intervention in patients with a renal artery aneurysm (RAA) include the following [20, 8, 13, 14] : Rupture Symptomatic RAA - Hypertension (from associated renal artery stenosis, refractory to medical management), pain, renal ischemia or infarction secondary to embolization from the aneurysm sac RAAs in females who are pregnant or are contemplating pregnancy Diameter greater than 2 cm Enlarging RAA RAA associated with acute dissection Currently, there is no consensus regarding the size at which an RAA should be repaired in an asymptomatic patient. Experts have recommended RAA repair at diameters ranging from 1.5 to 3 cm, [8] though most suggest 2 cm. Some reports have even suggest that larger asymptomatic saccular aneurysms may be managed expectantly. Note that aneurysm rupture at a diameter of 1.5 cm has been reported. Complete calcification of the wall of the aneurysm sac manifests in about 40% of patients. This was once believed to confer protection against rupture [21] ; however, this belief has since been questioned. [30] Asymptomatic, small (<2 cm in diameter) RAAs do not usually require treatment. One notable exception is an RAA in a woman who is pregnant or contemplating pregnancy. In view of the increased risk of rupture in such cases, even small asymptomatic aneurysms should be repaired in this population. For diagnosis and preinterventional planning, gadolinium-enhanced magnetic resonance angiography (MRA) and computed tomography (CT) angiography (CTA) with three-dimensional (3D) reconstruction have essentially replaced conventional arteriography. Regular follow-up examination with ultrasonography (US) or CT) is recommended in patients who are treated expectantly. Spontaneous cure by thrombosis of small aneurysms has been described. Further refinements in endovascular techniques may allow more RAAs to be treated in this manner. So far, excellent short- and intermediate-term results have been described in the literature [40] ; however, there remains a need for further long-term outcome data.

Scleroderma
Scleroderma samer kareem 1,746 Views • 2 years ago

Scleroderma (skleer-oh-DUR-muh) is a group of rare diseases that involve the hardening and tightening of the skin and connective tissues — the fibers that provide the framework and support for your body. In some people, scleroderma affects only the skin. But in many people, scleroderma also harms structures beyond the skin — such as blood vessels, internal organs and the digestive tract. Signs and symptoms vary, depending on which structures are affected. Scleroderma affects women more often than men and most commonly occurs between the ages of 30 and 50. While there is no cure for scleroderma, a variety of treatments can ease symptoms and improve quality of life.

Epididymitis

Epididymitis is infection or less frequently, inflammation of the epididymis (the coiled tube on the back of the testicle). The majority of men that develop epididymitis develop it because of a bacterial infection. Although males of any age can develop epididymitis, it occurs most frequently between ages of 20 to 39.

Breast Abscess
Breast Abscess samer kareem 5,407 Views • 2 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).

The goal of breast cancer surgery is to remove the entire tumor from the breast. Some of the lymph nodes in the underarm area (axillary nodes) may also be removed to see if cancer cells are present.

Anatomy and Physiology of The Heart
Anatomy and Physiology of The Heart samer kareem 8,265 Views • 2 years ago

The heart itself is made up of 4 chambers, 2 atria and 2 ventricles. De-oxygenated blood returns to the right side of the heart via the venous circulation. It is pumped into the right ventricle and then to the lungs where carbon dioxide is released and oxygen is absorbed. The oxygenated blood then travels back to the left side of the heart into the left atria, then into the left ventricle from where it is pumped into the aorta and arterial circulation.

Antiarrhythmics are drugs that are used to treat abnormal heart rhythms resulting from irregular electrical activity of the heart. There are many different types of antiarrhythmic drugs. Examples include: Amiodarone (Cordarone) Flecainide (Tambocor) Procainamide (Procanbid) Sotalol (Betapace) In addition, there are other types of heart drugs that can be used to treat arrhythmias, including: Beta-blockers such as metoprolol or Toprol XL, which reduce the heart's workload and heart rate. Calcium channel blockers such as verapamil or Calan, which also reduces the heart rate.

Mesentery - A New Organ Identified In Human Body
Mesentery - A New Organ Identified In Human Body Scott 10,167 Views • 2 years ago

an. 4, 2017 -- Scientists say they've identified a new organ in the body -- a swath of tissue dubbed the mesentery that connects the intestine to the abdomen and holds everything in place. For years, anatomical experts have thought the organ was composed of several different segments of tissue, as opposed to being one single structure, according to Discover magazine. Since an organ must be one structure that performs a vital function, it was not deemed worthy of organ status. But recent research from doctors at the University Hospital Limerick in Ireland shows that the mesentery is actually one single band of tissue, the magazine reported Tuesday. It begins at the pancreas and wraps around the small intestine and colon. Its purpose: to hold these organs in position so they can perform their respective functions. "Without it you can't live," lead researcher Dr. J. Calvin Coffey, a colorectal surgeon at Limerick, told the magazine. "There are no reported instances of a Homo sapien living without a mesentery." "Understanding how and why our digestive system is arranged the way it is could be crucial to our understanding of diseases like Crohn's and irritable bowel syndrome," Coffey added. "There are a lot of diseases that we are stalled on, and we need to refresh our approach to these diseases," Coffey said. "Now that we've clarified its [the mesentery's] structure, we can systematically examine it. We're at a very exciting place right now." The discovery was published recently in the Lancet Gastroenterology & Hepatology journal.

Your body needs bile, but if it has too much cholesterol in it, that makes gallstones more likely. It can also happen if your gallbladder can't empty properly. Pigment stones are more common in people with certain medical conditions, such as cirrhosis (a liver disease) or blood diseases such as sickle cell anemia.

Difference between arteriosclerosis and atherosclerosis
Difference between arteriosclerosis and atherosclerosis samer kareem 1,813 Views • 2 years ago

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.
