ThrombophilieLe terme thrombophilie désigne l'état de patients qui présentent une prédisposition particulière aux thromboses. Il recouvre deux situations médicales différentes : soit une pathologie générale favorisant l’apparition de thrombose. Ces manifestations thrombotiques se manifestent essentiellement au niveau veineux. soit une hypercoagulabilité du sang lié à un trouble de la coagulation sanguine La thrombophilie peut être « primitive » ou « constitutionnelle » (présence d'une anomalie génétique) ou « secondaire » ou « acquise » (due à une maladie acquise qui perturbe la coagulation).
Drug-eluting stentA drug-eluting stent (DES) is a peripheral or coronary stent (a scaffold) placed into narrowed, diseased peripheral or coronary arteries that slowly release a drug to block cell proliferation. This prevents fibrosis that, together with clots (thrombi), could otherwise block the stented artery, a process called restenosis. The stent is usually placed within the peripheral or coronary artery by an interventional cardiologist or interventional radiologist during an angioplasty procedure.
Coronary catheterizationA coronary catheterization is a minimally invasive procedure to access the coronary circulation and blood filled chambers of the heart using a catheter. It is performed for both diagnostic and interventional (treatment) purposes. Coronary catheterization is one of the several cardiology diagnostic tests and procedures. Specifically, through the injection of a liquid radiocontrast agent and illumination with X-rays, angiocardiography allows the recognition of occlusion, stenosis, restenosis, thrombosis or aneurysmal enlargement of the coronary artery lumens; heart chamber size; heart muscle contraction performance; and some aspects of heart valve function.
Intraparenchymal hemorrhageIntraparenchymal hemorrhage (IPH) is one form of intracerebral bleeding in which there is bleeding within brain parenchyma. The other form is intraventricular hemorrhage (IVH). Intraparenchymal hemorrhage accounts for approximately 8-13% of all strokes and results from a wide spectrum of disorders. It is more likely to result in death or major disability than ischemic stroke or subarachnoid hemorrhage, and therefore constitutes an immediate medical emergency.
Head injuryA head injury is any injury that results in trauma to the skull or brain. The terms traumatic brain injury and head injury are often used interchangeably in the medical literature. Because head injuries cover such a broad scope of injuries, there are many causes—including accidents, falls, physical assault, or traffic accidents—that can cause head injuries. The number of new cases is 1.7 million in the United States each year, with about 3% of these incidents leading to death.
Cerebrospinal fluid leakA cerebrospinal fluid leak (CSF leak or CSFL) is a medical condition where the cerebrospinal fluid (CSF) surrounding the brain or spinal cord leaks out of one or more holes or tears in the dura mater. A cerebrospinal fluid leak can be either cranial or spinal, and these are two different disorders. A spinal CSF leak can be caused by one or more meningeal diverticula or CSF-venous fistulas not associated with an epidural leak.
Induced comaAn induced coma also known as a medically induced coma (MIC), barbiturate-induced coma, or drug-induced coma is a temporary coma (a deep state of unconsciousness) brought on by a controlled dose of an anesthetic drug, often a barbiturate such as pentobarbital or thiopental. Other intravenous anesthetic drugs such as midazolam or propofol may be used. Drug-induced comas are used to protect the brain during major neurosurgery, as a last line of treatment in certain cases of status epilepticus that have not responded to other treatments, and in refractory intracranial hypertension following traumatic brain injury.
Coronary stentA coronary stent is a tube-shaped device placed in the coronary arteries that supply blood to the heart, to keep the arteries open in the treatment of coronary heart disease. It is used in a procedure called percutaneous coronary intervention (PCI). Coronary stents are now used in more than 90% of PCI procedures. Stents reduce angina (chest pain) and have been shown to improve survival and decrease adverse events in an acute myocardial infarction. Similar stents and procedures are used in non-coronary vessels (e.
Système circulatoire400px|vignette|Schéma du système circulatoire humain. En biologie, un est un système d'organes en circuit permettant le déplacement de fluides dans un organisme. Le système circulatoire a pour rôle d'assurer le transport et l'échange interne des ressources (notamment les nutriments et le dioxygène) vers les cellules de l'organisme, ainsi que de se charger de la collecte des déchets, par exemple du dioxyde de carbone.
Ischémie mésentériqueL'ischémie mésentérique (ou ischémie intestinale) est la conséquence de l'obstruction d'une artère à destinée digestive. Elle peut être aiguë et se compliquer d'un infarctus (gangrène de l'intestin), ou chronique (angor mésentérique). L'intestin est irrigué par trois artères naissant à la partie antérieure de l'aorte abdominale : le tronc cœliaque dont les branches vascularisent l'estomac, le duodénum, la rate, le foie et le pancréas ; l'artère mésentérique supérieure vascularisant l'intestin grêle et la partie droite du côlon ; l'artère mésentérique inférieure vascularisant la partie gauche du côlon.
