General Information
- Angioneurotic edema (angioedema) is an acutely developing local swelling of the skin, subcutaneous tissue, mucous membranes of an allergic or pseudoallergic nature, most often occurring on the face (lips, eyelids, cheek, tongue), less often – on the mucous membranes (respiratory tract, gastrointestinal tract, genitourinary organs). With the develop...
Causes
- Acquired angioneurotic edema often develops in response to the penetration of an allergen into the body – a drug, a food product, as well as with insect bites and stings. The resulting acute allergic reaction with the release of inflammatory mediators increases the permeability of blood vessels located in the subcutaneous fat and submucosal layer, and leads to the appearance of l…
Classification
- According to clinical manifestations, there is an acute course of angioneurotic edema lasting less than 1.5 months and a chronic course when the pathological process lasts 1.5-3 months or longer. Isolated and combined with urticaria angioedema are isolated. Depending on the mechanism of edema development, there are diseases caused by a violation of the regulation o…
Symptoms of Angioneurotic Edema
- Angioedema develops, as a rule, acutely within 2-5 minutes, less often angioedema can form gradually with an increase in symptoms for several hours. Typical localization sites are areas of the body where there is loose fiber: in the area of the eyelids, cheeks, lips, on the mucous membrane of the oral cavity, on the tongue, as well as on the scrotum in men. If edema develop…
Diagnostics
- The characteristic clinical picture, typical for angioneurotic edema with localization on the face and other exposed areas of the body, allows you to quickly establish the correct diagnosis. The situation is more difficult when a picture of an “acute abdomen” or a transient ischemic attack appears, when it is necessary to differentiate the observed symptoms with a number of disease…

With allergic angioedema, glucocorticoids, antihistamines are administered, contact with a potential allergen is eliminated, infusion therapy, enterosorption is …
Prognosis and Prevention
- The outcome of angioneurotic edema depends on the severity of the manifestations and the timeliness of therapeutic measures. Thus, laryngeal edema in the absence of emergency care ends in death. Recurrent urticaria, combined with angioneurotic edema and lasting for six months or more, is further observed in 40% of patients for another 10 years, and 50% may experience pr…
