Coronary Stent Procedure
Coronary Stent Procedure samer kareem 2,249 Views • 3 years ago

Before the angioplasty procedure begins, you will receive some pain medicine. You may also be given medicine that relaxes you, and blood thinning medicines to prevent a blood clot from forming. You will lie on a padded table. Your doctor will insert a flexible tube (catheter) through a surgical cut into an artery. Sometimes the catheter will be placed in your arm or wrist, or in your upper leg or groin area. You will be awake during the procedure. The doctor will use live x-ray pictures to carefully guide the catheter up into your heart and arteries. Dye will be injected into your body to highlight blood flow through the arteries. This helps the doctor see any blockages in the blood vessels that lead to your heart. A guide wire is moved into and across the blockage. A balloon catheter is pushed over the guide wire and into the blockage. The balloon on the end is blown up (inflated). This opens the blocked vessel and restores proper blood flow to the heart. A wire mesh tube (stent) may then be placed in this blocked area. The stent is inserted along with the balloon catheter. It expands when the balloon is inflated. The stent is left there to help keep the artery open

Common Benign Pain Syndromes--Symptoms and Etiology:
1. Non-specific musculoskeletal pain: This is the most common cause of back pain. Patients present with lumbar area pain that does not radiate, is worse with activity, and improves with rest. There may or may not be a clear history of antecedent over use or increased activity. The pain is presumably caused by irritation of the paraspinal muscles, ligaments or vertebral body articulations. However, a precise etiology is difficulty to identify.
2. Radicular Symptoms: Often referred to as "sciatica," this is a pain syndrome caused by irritation of one of the nerve roots as it exits the spinal column. The root can become inflamed as a result of a compromised neuroforamina (e.g. bony osteophyte that limits size of the opening) or a herniated disc (the fibrosis tears, allowing the propulsus to squeeze out and push on the adjacent root). Sometimes, it's not precisely clear what has lead to the irritation. In any case, patient's report a burning/electric shock type pain that starts in the low back, traveling down the buttocks and along the back of the leg, radiating below the knee. The most commonly affected nerve roots are L5 and S1.
3. Spinal Stenosis: Pain starts in the low back and radiates down the buttocks bilaterally, continuing along the backs of both legs. Symptoms are usually worse with walking and improve when the patient bends forward. Patient's may describe that they relieve symptoms by leaning forward on their shopping carts when walking in a super market. This is caused by spinal stenosis, a narrowing of the central canal that holds the spinal cord. The limited amount of space puts pressure on the nerve roots when the patient walks, causing the symptoms (referred to as neurogenic claudication). Spinal stenosis can be congenital or develop over years as a result of djd of the spine. As opposed to true claudication (pain in calfs/lower legs due to arterial insufficiency), pain resolves very quickly when person stops walking and assumes upright position. Also, peripheral pulses should be normal.
4. Mixed symptoms: In some patients, more then one process may co-exist, causing elements of more then one symptom syndrome to co-exist.

Penile Implants
Penile Implants samer kareem 4,915 Views • 3 years ago

A penile prosthesis is another treatment option for men with erectile dysfunction (ED). These devices are either malleable or inflatable. The simplest type of prosthesis consists of a pair of malleable (bendable) rods surgically implanted within the erection chambers of the penis. With this type of implant the penis is always semi-rigid and merely needs to be lifted or adjusted into the erect position to initiate sex. Today, many men choose a hydraulic, inflatable prosthesis, which allows a man to have an erection whenever he chooses and is much easier to conceal. It is also more natural.

Diagnosis To determine the most appropriate treatment for your stroke, your emergency team needs to evaluate the type of stroke you're having and the areas of your brain affected by the stroke. They also need to rule out other possible causes of your symptoms, such as a brain tumor or a drug reaction. Your doctor may use several tests to determine your risk of stroke, including: Stroke consultation Stroke consultation Stroke consultation at Mayo Clinic Brain tissue damaged by stroke CT scan of brain tissue damaged by stroke Cerebral angiogram Cerebral angiogram Physical examination. Your doctor will ask you or a family member what symptoms you've been having, when they started and what you were doing when they began. Your doctor then will evaluate whether these symptoms are still present. Your doctor will want to know what medications you take and whether you have experienced any head injuries. You'll be asked about your personal and family history of heart disease, transient ischemic attack and stroke. Your doctor will check your blood pressure and use a stethoscope to listen to your heart and to listen for a whooshing sound (bruit) over your neck (carotid) arteries, which may indicate atherosclerosis. Your doctor may also use an ophthalmoscope to check for signs of tiny cholesterol crystals or clots in the blood vessels at the back of your eyes. Blood tests. You may have several blood tests, which tell your care team how fast your blood clots, whether your blood sugar is abnormally high or low, whether critical blood chemicals are out of balance, or whether you may have an infection. Managing your blood's clotting time and levels of sugar and other key chemicals will be part of your stroke care. Computerized tomography (CT) scan. A CT scan uses a series of X-rays to create a detailed image of your brain. A CT scan can show a hemorrhage, tumor, stroke and other conditions. Doctors may inject a dye into your bloodstream to view your blood vessels in your neck and brain in greater detail (computerized tomography angiography). There are different types of CT scans that your doctor may use depending on your situation. Magnetic resonance imaging (MRI). An MRI uses powerful radio waves and magnets to create a detailed view of your brain. An MRI can detect brain tissue damaged by an ischemic stroke and brain hemorrhages. Your doctor may inject a dye into a blood vessel to view the arteries and veins and highlight blood flow (magnetic resonance angiography, or magnetic resonance venography). Carotid ultrasound. In this test, sound waves create detailed images of the inside of the carotid arteries in your neck. This test shows buildup of fatty deposits (plaques) and blood flow in your carotid arteries. Cerebral angiogram. In this test, your doctor inserts a thin, flexible tube (catheter) through a small incision, usually in your groin, and guides it through your major arteries and into your carotid or vertebral artery. Then your doctor injects a dye into your blood vessels to make them visible under X-ray imaging. This procedure gives a detailed view of arteries in your brain and neck. Echocardiogram. An echocardiogram uses sound waves to create detailed images of your heart. An echocardiogram can find a source of clots in your heart that may have traveled from your heart to your brain and caused your stroke. You may have a transesophageal echocardiogram. In this test, your doctor inserts a flexible tube with a small device (transducer) attached into your throat and down into the tube that connects the back of your mouth to your stomach (esophagus). Because your esophagus is directly behind your heart, a transesophageal echocardiogram can create clear, detailed ultrasound images of your heart and any blood clots. Treatment Emergency treatment for stroke depends on whether you're having an ischemic stroke blocking an artery — the most common kind — or a hemorrhagic stroke that involves bleeding into the brain. Ischemic stroke To treat an ischemic stroke, doctors must quickly restore blood flow to your brain. Emergency treatment with medications. Therapy with clot-busting drugs must start within 4.5 hours if they are given into the vein — and the sooner, the better. Quick treatment not only improves your chances of survival but also may reduce complications. You may be given: Intravenous injection of tissue plasminogen activator (tPA). This injection of recombinant tissue plasminogen activator (tPA), also called alteplase, is considered the gold standard treatment for ischemic stroke. An injection of tPA is usually given through a vein in the arm. This potent clot-busting drug ideally is given within three hours. In some instances, tPA can be given up to 4.5 hours after stroke symptoms begin. This drug restores blood flow by dissolving the blood clot causing your stroke, and it may help people who have had strokes recover more fully. Your doctor will consider certain risks, such as potential bleeding in the brain, to determine if tPA is appropriate for you. Emergency endovascular procedures. Doctors sometimes treat ischemic strokes with procedures performed directly inside the blocked blood vessel. These procedures must be performed as soon as possible, depending on features of the blood clot: Medications delivered directly to the brain. Doctors may insert a long, thin tube (catheter) through an artery in your groin and thread it to your brain to deliver tPA directly into the area where the stroke is occurring. This is called intra-arterial thrombolysis. The time window for this treatment is somewhat longer than for intravenous tPA, but is still limited. Removing the clot with a stent retriever. Doctors may use a catheter to maneuver a device into the blocked blood vessel in your brain and trap and remove the clot. This procedure is particularly beneficial for people with large clots that can't be completely dissolved with tPA, though this procedure is often performed in combination with intravenous tPA. Several large and recent studies suggest that, depending on the location of the clot and other factors, endovascular therapy might be the most effective treatment. Endovascular therapy has been shown to significantly improve outcomes and reduce long-term disability after ischemic stroke. Other procedures. To decrease your risk of having another stroke or transient ischemic attack, your doctor may recommend a procedure to open up an artery that's narrowed by plaque. Doctors sometimes recommend the following procedures to prevent a stroke. Options will vary depending on your situation: Carotid endarterectomy. In a carotid endarterectomy, a surgeon removes plaques from arteries that run along each side of your neck to your brain (carotid arteries). In this procedure, your surgeon makes an incision along the front of your neck, opens your carotid artery and removes plaque that blocks the carotid artery. Your surgeon then repairs the artery with stitches or a patch made from a vein or artificial material (graft). The procedure may reduce your risk of ischemic stroke. However, a carotid endarterectomy also involves risks, especially for people with heart disease or other medical conditions. Angioplasty and stents. In an angioplasty, a surgeon usually accesses your carotid arteries through an artery in your groin. Here, your surgeon can gently and safely navigate to the carotid arteries in your neck. A balloon is then inflated to expand the narrowed artery. Then a stent can be inserted to support the opened artery. Hemorrhagic stroke Emergency treatment of hemorrhagic stroke focuses on controlling your bleeding and reducing pressure in your brain. You might also need surgery to help reduce future risk. Emergency measures. If you take warfarin (Coumadin, Jantoven) or anti-platelet drugs such as clopidogrel (Plavix) to prevent blood clots, you may be given drugs or transfusions of blood products to counteract the blood thinners' effects. You may also be given drugs to lower pressure in your brain (intracranial pressure), lower your blood pressure, prevent vasospasm or prevent seizures. Once the bleeding in your brain stops, treatment usually involves supportive medical care while your body absorbs the blood. Healing is similar to what happens while a bad bruise goes away. If the area of bleeding is large, your doctor may perform surgery to remove the blood and relieve pressure on your brain. Surgical blood vessel repair. Surgery may be used to repair blood vessel abnormalities associated with hemorrhagic strokes. Your doctor may recommend one of these procedures after a stroke or if an aneurysm or arteriovenous malformation (AVM) or other type of vascular malformation caused your hemorrhagic stroke: Surgical clipping. A surgeon places a tiny clamp at the base of the aneurysm, to stop blood flow to it. This clamp can keep the aneurysm from bursting, or it can prevent re-bleeding of an aneurysm that has recently hemorrhaged. Coiling (endovascular embolization). A surgeon inserts a catheter into an artery in your groin and guides it to your brain using X-ray imaging. Tiny detachable coils are guided into the aneurysm (aneurysm coiling). The coils fill the aneurysm, which blocks blood flow into the aneurysm and causes the blood to clot. Surgical AVM removal. Surgeons may remove a smaller AVM if it's located in an accessible area of your brain, to eliminate the risk of rupture and lower the risk of hemorrhagic stroke. However, it's not always possible to remove an AVM if its removal would cause too large a reduction in brain function, or if it's large or located deep within your brain. Stereotactic radiosurgery. Using multiple beams of highly focused radiation, stereotactic radiosurgery is an advanced minimally invasive treatment used to repair vascular malformations. Stroke recovery and rehabilitation Brain hemisphere connections Brain hemisphere connections After emergency treatment, stroke care focuses on helping you recover as much function as possible and return to independent living. The impact of your stroke depends on the area of the brain involved and the amount of tissue damaged. If your stroke affected the right side of your brain, your movement and sensation on the left side of your body may be affected. If your stroke damaged the brain tissue on the left side of your brain, your movement and sensation on the right side of your body may be affected. Brain damage to the left side of your brain may cause speech and language disorders. In addition, if you've had a stroke, you may have problems with breathing, swallowing, balancing and vision. Most stroke survivors receive treatment in a rehabilitation program. Your doctor will recommend the most rigorous therapy program you can handle based on your age, overall health and degree of disability from your stroke. Your doctor will take into consideration your lifestyle, interests and priorities, and the availability of family members or other caregivers. Your rehabilitation program may begin before you leave the hospital. After discharge, you might continue your program in a rehabilitation unit of the same hospital, another rehabilitation unit or skilled nursing facility, an outpatient unit, or your home. Every person's stroke recovery is different. Depending on your condition, your treatment team may include: Doctor trained in brain conditions (neurologist) Rehabilitation doctor (physiatrist) Nurse Dietitian Physical therapist Occupational therapist Recreational therapist Speech pathologist Social worker Case manager Psychologist or psychiatrist Chaplain Speech therapy session Speech therapy is often a part of stroke rehabilitation. Treatment outcomes One way to evaluate the care of patients diagnosed with stroke is to look at the percentage of patients receiving the timely and effective care measures that are appropriate. The goal is 100 percent. The graphs below display the percentage of eligible Mayo Clinic patients diagnosed with stroke receiving all of the appropriate care measures.

Pulmonary edema, lungs
Pulmonary edema, lungs samer kareem 7,742 Views • 3 years ago

Expand Section. Pulmonary edema is often caused by congestive heart failure. When the heart is not able to pump efficiently, blood can back up into the veins that take blood through the lungs. As the pressure in these blood vessels increases, fluid is pushed into the air spaces (alveoli) in the lungs.

Laparoscopic Appendicectomy Surgery Video
Laparoscopic Appendicectomy Surgery Video Mohamed Ibrahim 22,340 Views • 3 years ago

What is the Appendix? The appendix is a long narrow tube (a few inches in length) that attaches to the first part of the colon. It is usually located in the lower right quadrant of the abdominal cavity. The appendix produces a bacteria destroying protein called immunoglobulins, which help fight infection in the body. Its function, however, is not essential. People who have had appendectomies do not have an increased risk toward infection. Other organs in the body take over this function once the appendix has been removed. What is a Laparoscopic Appendectomy? Appendicitis is one of the most common surgical problems. One out of every 2,000 people has an appendectomy sometime during their lifetime. Treatment requires an operation to remove the infected appendix. Traditionally, the appendix is removed through an incision in the right lower abdominal wall. In most laparoscopic appendectomies, surgeons operate through 3 small incisions (each ¼ to ½ inch) while watching an enlarged image of the patient’s internal organs on a television monitor. In some cases, one of the small openings may be lengthened to complete the procedure. Advantages of Laparoscopic Appendectomy Results may vary depending upon the type of procedure and patient’s overall condition. Common advantages are: Less postoperative pain May shorten hospital stay May result in a quicker return to bowel function Quicker return to normal activity Better cosmetic results Are You a Candidate for Laparoscopic Appendectomy? Although laparoscopic appendectomy has many benefits, it may not be appropriate for some patients. Early, non-ruptured appendicitis usually can be removed laparoscopically. Laparoscopic appendectomy is more difficult to perform if there is advanced infection or the appendix has ruptured. A traditional, open procedure using a larger incision may be required to safely remove the infected appendix in these patients.

Bilateral renal arterial stenosis
Bilateral renal arterial stenosis samer kareem 4,013 Views • 3 years ago

Renal artery stenosis is the narrowing of one or more arteries that carry blood to your kidneys (renal arteries). Narrowing of the arteries prevents normal amounts of oxygen-rich blood from reaching your kidneys. Your kidneys need adequate blood flow to help filter waste products and remove excess fluids. Reduced blood flow may increase blood pressure in your whole body (systemic blood pressure) and injure kidney tissue.

Multiple sclerosis (MS) involves an immune-mediated process in which an abnormal response of the body’s immune system is directed against the central nervous system (CNS). The CNS is made up of the brain, spinal cord and optic nerves. Within the CNS, the immune system causes inflammation that damages myelin — the fatty substance that surrounds and insulates the nerve fibers — as well as the nerve fibers themselves, and the specialized cells that make myelin. When myelin or nerve fibers are damaged or destroyed in MS, messages within the CNS are altered or stopped completely. Damage to areas of the CNS may produce a variety of neurological symptoms that will vary among people with MS in type and severity The damaged areas develop scar tissue which gives the disease its name – multiple areas of scarring or multiple sclerosis. The cause of MS is not known, but it is believed to involve genetic susceptibility, abnormalities in the immune system and environmental factors that combine to trigger the disease. People with MS typically experience one of four disease courses. There are over a dozen treatments to help modify the MS disease process.

Pregnancy ultrasounds are performed mainly using transabdominal ultrasound. For many women, especially after 8 weeks gestation, sufficient information about the baby may be obtained with transabdominal ultrasound only. However, in the early pregnancy, the developing embryo is very small (at 6 weeks gestation, the baby is only 5-9mm long) and a transvaginal ultrasound may be required to get a better image of the baby. Transvaginal ultrasound is safe and commonly performed during all stages of pregnancy, including the first trimester. It will not harm you or your baby.
