Pulmonary Thromboendarterectomy
In thoracic surgery, a pulmonary thromboendarterectomy (PTE), also referred to as pulmonary endarterectomy (PEA), is an operation that removes organized clotted blood (thrombus) from the pulmonary arteries, which supply blood to the lungs. Indication Surgery is indicated in patients with pulmonary artery emboli that are surgically accessible. Thrombi are usually the cause of recurrent/chronic pulmonary emboli and therefore of chronic thromboembolic pulmonary hypertension (CTEPH). PTE is the only definitive treatment option available for CTEPH.Chronic thromboembolic pulmonary hypertension. Fedullo P, Kerr KM, Kim NH, Auger WR Am J Respir Crit Care Med. 2011;183(12):1605. Due to the nature of the procedure, patients with significant hemodynamic or ventilation complications or impairments may be unable to undergo PTE. Description of the surgery A PTE has significant risk; mortality for the operation is typically 5%, but less in centers with high volume and experience. Individuals w ...

Cardiothoracic Surgery
Cardiothoracic surgery is the field of medicine involved in surgical treatment of organs inside the thoracic cavity — generally treatment of conditions of the heart (heart disease), lungs ( lung disease), and other pleural or mediastinal structures. In most countries, cardiothoracic surgery is further subspecialized into cardiac surgery (involving the heart and the great vessels) and thoracic surgery (involving the lungs, esophagus, thymus, etc.); the exceptions are the United States, Australia, New Zealand, the United Kingdom, and some European Union countries such as Portugal. Training A cardiac surgery residency typically comprises anywhere from four to six years (or longer) of training to become a fully qualified surgeon. Cardiac surgery training may be combined with thoracic surgery and / or vascular surgery and called cardiovascular (CV) / cardiothoracic (CT) / cardiovascular thoracic (CVT) surgery. Cardiac surgeons may enter a cardiac surgery residency directly from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extracorporeal Circulation
An extracorporeal is a medical procedure which is performed outside the body. Extracorporeal devices are the artificial organs that remain outside the body while treating a patient. Extracorporeal devices are useful in hemodialysis and cardiac surgery. Circulatory procedures A procedure in which blood is taken from a patient's circulation to have a process applied to it before it is returned to the circulation. All of the apparatus carrying the blood outside the body is termed the extracorporeal circuit. * Apheresis * Autotransfusion * Hemodialysis * Hemofiltration * Plasmapheresis * Extracorporeal carbon dioxide removal * Extracorporeal cardiopulmonary resuscitation * Extracorporeal membrane oxygenation (ECMO) * Cardiopulmonary bypass during open heart surgery. Other procedures Extracorporeal shockwave lithotripsy Extracorporeal shockwave therapy (ESWT) is a non-invasive, out-patient alternative to surgery for those with many joint and tendon disorders. ESWT sends acoustic s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deep Hypothermic Circulatory Arrest
Deep hypothermic circulatory arrest (DHCA) is a surgical technique that induces deep medical hypothermia. It involves cooling the body to temperatures between 20 °C (68 °F) to 25 °C (77 °F), and stopping blood circulation and brain function for up to one hour. It is used when blood circulation to the brain must be stopped because of delicate surgery within the brain, or because of surgery on large blood vessels that lead to or from the brain. DHCA is used to provide a better visual field during surgery due to the cessation of blood flow. DHCA is a form of carefully managed clinical death in which heartbeat and all brain activity cease. At normal body temperature of 37 °C only several minutes of stopped blood circulation causes changes within the brain leading to permanent damage after circulation is restored. Reducing body temperature extends the time interval that such stoppage can be survived. At a brain temperature of 14 °C, blood circulation ...

Pulmonary Thrombectomy
A pulmonary thrombectomy is an emergency surgical procedure used to remove blood clots from the pulmonary arteries. Mechanical thrombectomies can be surgical (surgical thrombectomy) or percutaneous (percutaneous thrombectomy). Surgical thrombectomies were once popular but were abandoned because of poor long-term outcomes. Recently, in selected patients, they have gone through a resurgence with the revision of the surgical technique. Relation to PTE Pulmonary thrombectomies and pulmonary thromboendarterectomies (PTEs) are both operations that remove thrombus. Aside from this similarity they differ in many ways. *PTEs are done on a nonemergency basis while pulmonary thrombectomies are typically done as an emergency procedure. *PTEs typically are done using hypothermia and full cardiac arrest. *PTEs are done for chronic pulmonary embolism, thrombectomies for severe acute pulmonary embolism. *PTEs are generally considered a very effective treatment, surgical thrombectomies are an ...

Right Ventricular Hypertrophy
Right ventricular hypertrophy (RVH) is a condition defined by an abnormal enlargement of the cardiac muscle surrounding the right ventricle. The right ventricle is one of the four chambers of the heart. It is located towards the lower-end of the heart and it receives blood from the right atrium and pumps blood into the lungs. Since RVH is an enlargement of muscle it arises when the muscle is required to work harder. Therefore, the main causes of RVH are pathologies of systems related to the right ventricle such as the pulmonary artery, the tricuspid valve or the airways. RVH can be benign and have little impact on day-to-day life or it can lead to conditions such as heart failure, which has a poor prognosis. Signs and symptoms Symptoms Although presentations vary, individuals with right ventricular hypertrophy can experience symptoms that are associated with pulmonary hypertension, heart failure and/or a reduced cardiac output. These include: * Difficulty breathing on exertio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volumetric Flow
In physics and engineering, in particular fluid dynamics, the volumetric flow rate (also known as volume flow rate, or volume velocity) is the volume of fluid which passes per unit time; usually it is represented by the symbol (sometimes ). It contrasts with mass flow rate, which is the other main type of fluid flow rate. In most contexts a mention of ''rate of fluid flow'' is likely to refer to the volumetric rate. In hydrometry, the volumetric flow rate is known as '' discharge''. Volumetric flow rate should not be confused with volumetric flux, as defined by Darcy's law and represented by the symbol , with units of m3/(m2·s), that is, m·s−1. The integration of a flux over an area gives the volumetric flow rate. The SI unit is cubic metres per second (m3/s). Another unit used is standard cubic centimetres per minute (SCCM). In US customary units and imperial units, volumetric flow rate is often expressed as cubic feet per second (ft3/s) or gallons per minute (eithe ...
