Voorbeelden van het gebruik van EXTRAVASATION in een zin

• Battle's sign consists of bruising over the mastoid process as a result of extravasation of blood along the path of the posterior auricular artery.
• Long term complications include incontinence, urethral stricture, urine retention, urinary tract infection, urine extravasation and bladder stones.
• The smaller fragment called C3a serves to increase vascular permeability and promote extravasation of phagocytes, while the larger C3b fragment can be used as an opsonin or bind to either type of C3 convertase to form the trimolecular C5 convertase to activate C5 for the membrane attack complex.
• Toxicities include bone marrow suppression (which is dose-limiting), gastrointestinal toxicity, potent vesicant (blister-forming) activity, and extravasation injury (forms deep ulcers).
• It may be stored in crash carts to counteract severe peripheral vasoconstriction secondary to extravasation of peripherally placed vasopressor infusions, typically of norepinephrine.
• Recent clinical trials have shown that Totect (USA) or Savene (Europe) (dexrazoxane for extravasation) is effective in preventing the progression of anthracycline extravasation into progressive tissue necrosis.
• Red blood cell extravasation and deposition of hemosiderin that follows clinically appear as hyperpigmentation, which can occur in a reticular distribution.
• During leukocyte extravasation, white blood cells move in response to cytokines from the blood into diseased or infected tissues, usually in the direction of a chemical gradient, in a process called chemotaxis.
• A ranula is a mucus extravasation cyst involving a sublingual gland and is a type of mucocele found on the floor of the mouth.
• In contrast to the endothelial cells from other vessels, the high endothelial cells of HEVs have a distinctive appearance, consisting of a cuboidal morphology and with various receptors to interact with leukocytes (express specialized ligands for lymphocytes and are able to support high levels of lymphocyte extravasation).
• The abdomen, the central nervous system, and the organs (including the lungs) are typically spared, but the extravasation in the extremities is sufficiently massive to cause circulatory shock and compartment syndromes, with a dangerous hypotension (low blood pressure), hemoconcentration (thickening of the blood) and hypoalbuminemia (drop in albumin, a major protein) in the absence of other causes for such abnormalities.
• In vitro and in vivo analyses show that exogenous and endogenous annexin A1 counter-regulate the activities of innate immune cells, particularly extravasation and the generation of proinflammatory mediators, which ensures that a sufficient level of activation is reached but not exceeded.
• Also, talin-1 drives extravasation mechanism through engineered human microvasculature in microfluidic systems.
• Leukocyte extravasation occurs mainly in post-capillary venules, where haemodynamic shear forces are minimised.
• Non contrasted CT scans might show an intimal flap, periaortic hematoma, luminal filling defect, aortic contour abnormality, pseudoaneurysm, contained rupture, vessel wall disruption, active extravasation of intravenous contrast from the aorta and is therefore useful to assess for minimal aortic injury.
• Anthracycline extravasation is defined as the unintentional installation or leakage into the perivascular or subcutaneous spaces during administration.
• Cysts of the salivary glands: mucous extravasation cyst; mucous retention cyst; ranula; polycystic (dysgenetic) disease of the parotid.
• Contrast agent is injected through the catheter, and when abnormal findings are observed, such as systemic–pulmonary shunts, proliferations of the capillary vessels, or extravasation of the contrast medium to the lung tissues, they were super selectively embolized using the 3 Fr microcatheter system.
• Before removing a cystostomy, a voiding cystourethrography should demonstrate no urine extravasation.
• The US Food and Drug Administration has approved hyaluronidase for the following indications: (1) subcutaneous fluid infusion (hypodermoclysis), (2) as an adjuvant to accelerate the absorption and dispersion of drugs in subcutaneous tissue or to manage extravasation, and (3) as an adjunct to promote the absorption of contrast media in urinary tract angiography (subcutaneous urography).
