Ventriculostomy Brain Surgery - 3d animation
Ventriculostomy Brain Surgery - 3d animation Scott 942 Views • 2 years ago

This 3D animation of brain surgery, shows how a ventriculostomy is performed, which is a neurosurgical procedure of creating a hole within a cerebral ventricle for drainage. It is most commonly performed on those with hydrocephalus, an abnormal buildup of fluid in the ventricles (cavities) deep within the brain. It's done by surgically penetrating the skull, dura mater, and brain such that the ventricular system ventricle of the brain is accessed.

When catheter drainage is temporary, it is commonly referred to as an external ventricular drain (EVD). When catheter drainage is permanent, it is usually referred to as a shunt.

There are many catheter-based ventricular shunts that are named for where they terminate, for example, a ventriculi-peritoneal shunt terminates in the peritoneal cavity, a ventriculoarterial shunt terminates within the atrium of the heart, etc. The most common entry point on the skull is called Kocher's point. An EVD ventriculostomy is done primarily to monitor the intracranial pressure as well as to drain cerebrospinal fluid (CSF), primarily, or blood to relieve pressure from the central nervous system (CNS).

Asbestosis Disease
Asbestosis Disease samer kareem 1,622 Views • 2 years ago

Asbestosis is linked to chrysotile fibers. Chrysotile is one of the six known types of asbestos. Exposure occurs when someone breathes in the dangerous fibers. Extended exposure can lead to an accumulation of the fibers in lung tissues, setting the stage for long-term fibrosis (scarring). Over time, lung tissues thicken, causing pain and restricting breathing. Symptoms include labored breathing during routine tasks and exercise, chest pain and coughing. Doctors prescribe breathing treatments, prescription medication and sometimes surgery for people with asbestosis.

Open pneumothorax
Open pneumothorax samer kareem 1,367 Views • 2 years ago

A pneumothorax can be caused by a blunt or penetrating chest injury, certain medical procedures, or damage from underlying lung disease. Or it may occur for no obvious reason. Symptoms usually include sudden chest pain and shortness of breath. On some occasions, a collapsed lung can be a life-threatening event.

Myelomeningocele Closure
Myelomeningocele Closure samer kareem 2,756 Views • 2 years ago

Myelomeningocele remains the most complex congenital malformation of the central nervous system that is compatible with life. This lesion results when the neural tube fails to fold normally during postovulatory Days 21 to 27.[6] The exact cause of disorders remains under some historical debate and is not within the scope of this paper. Myelomeningocele within the context of this discussion refers only to lesions that involve an open caudal neural tube defect on the surface of the skin

A circulatory anastomosis is a connection (an anastomosis) between two blood vessels, such as between arteries (arterio-arterial anastomosis), between veins (veno-venous anastomosis) or between an artery and a vein (arterio-venous anastomosis). An end artery (or terminal artery) is an artery that is the only supply of oxygenated blood to a portion of tissue. Examples of an end artery include the splenic artery that supplies the spleen and the renal artery that supplies the kidneys.

A sleep disorder, or somnipathy, is a medical disorder of the sleep patterns of a person or animal. Some sleep disorders are serious enough to interfere with normal physical, mental, social and emotional functioning. Polysomnography and actigraphy are tests commonly ordered for some sleep disorders.

Transurethral Prostatectomy TURP
Transurethral Prostatectomy TURP Scott 234,839 Views • 2 years ago

Transurethral resection of the prostate (also known as TURP, plural TURPs and as a transurethral prostatic resection TUPR) is a urological operation. It is used to treat benign prostatic hyperplasia (BPH). As the name indicates, it is performed by visualising the prostate through the urethra and removing tissue by electrocautery or sharp dissection. This is considered the most effective treatment for BPH. This procedure is done with spinal or general anesthetic. A large triple lumen catheter is inserted through the urethra to irrigate and drain the bladder after the surgical procedure is complete. Outcome is considered excellent for 80-90% of BPH patients. Because of bleeding risks associated with the surgery, TURP is not considered safe for many patients with cardiac problems. As with all invasive procedures, the patient should first discuss medications they are taking with their doctor, most especially blood thinners or anticoagulants, such as warfarin (Coumadin), or aspirin. These may need to be discontinued prior to surgery. Postop complications include bleeding (most common), clotting and hyponatremia (due to bladder irrigation).

Additionally, transurethral resection of the prostate is associated with low but important morbidity and mortality.

Automated External Defibrillator
Automated External Defibrillator Doctor 10,411 Views • 2 years ago

An automated external defibrillator or AED is a portable electronic device that automatically diagnoses the potentially life threatening cardiac arrhythmias of ventricular fibrillation and ventricular tachycardia in a patient,[1] and is able to treat them through defibrillation, the application of electrical therapy which stops the arrhythmia, allowing the heart to reestablish an effective rhythm. The first AED was originally designed and created by American biomedical engineer Joshua L. Koelker and Italian emergency medical professional Jordan M. Blondino to allow defibrillation in common public places. AEDs are designed to be simple to use for the layman, and the use of AEDs is taught in many first aid, first responder, and basic life support (BLS) level CPR classes.

Pelvic organ prolapse occurs when a pelvic organ-such as your bladder-drops (prolapses) from its normal place in your lower belly and pushes against the walls of your vagina. This can happen when the muscles that hold your pelvic organs in place get weak or stretched from childbirth or surgery.

Abdominal Aortic Aneurysm
Abdominal Aortic Aneurysm samer kareem 2,457 Views • 2 years ago

An abdominal aortic aneurysm is an enlarged area in the lower part of the aorta, the major blood vessel that supplies blood to the body. The aorta, about the thickness of a garden hose, runs from your heart through the center of your chest and abdomen. Because the aorta is the body's main supplier of blood, a ruptured abdominal aortic aneurysm can cause life-threatening bleeding. Depending on the size and the rate at which your abdominal aortic aneurysm is growing, treatment may vary from watchful waiting to emergency surgery. Once an abdominal aortic aneurysm is found, doctors will closely monitor it so that surgery can be planned if it's necessary. Emergency surgery for a ruptured abdominal aortic aneurysm can be risky.

Mouth ulcers are sores that appear in the mouth, often on the inside of the cheeks. Mouth ulcers, also known as aphthous ulcers, can be painful when eating, drinking or brushing teeth. Occasional mouth ulcers are usually harmless and clear up on their own. Seek medical advice if they last longer than 3 weeks or keep coming back. Mouth ulcers cannot be caught from someone else. Up to 1 in 5 people get recurrent mouth ulcers.

CPAP, or continuous positive airway pressure, is a treatment that uses mild air pressure to keep the airways open. CPAP typically is used by people who have breathing problems, such as sleep apnea. CPAP also may be used to treat preterm infants whose lungs have not fully developed.
