O angioedema Angioedema Angioedema is a localized, self-limited (but potentially life-threatening), nonpitting, asymmetrical edema occurring in the deep layers of the skin and mucosal tissue. The common underlying pathophysiology involves inflammatory mediators triggering significant vasodilation and increased capillary permeability. Angioedema é um edema Edema Edema is a condition in which excess serous fluid accumulates in the body cavity or interstitial space of connective tissues. Edema is a symptom observed in several medical conditions. It can be categorized into 2 types, namely, peripheral (in the extremities) and internal (in an organ or body cavity). Edema assimétrico localizado, autolimitado (mas potencialmente fatal), não depressível, que ocorre nas camadas profundas da pele e do tecido mucoso. A fisiopatologia subjacente está relacionada com mediadores inflamatórios que promovem vasodilatação significativa e aumento da permeabilidade capilar. Clinicamente, o angioedema Angioedema Angioedema is a localized, self-limited (but potentially life-threatening), nonpitting, asymmetrical edema occurring in the deep layers of the skin and mucosal tissue.

The common underlying pathophysiology involves inflammatory mediators triggering significant vasodilation and increased capillary permeability. Angioedema for mediado por mastócitos, mas não quando este ocorre por aumento da bradicinina. Geralmente o diagnóstico é clínico, mas podem ser realizados testes Testes Gonadal Hormones adicionais, como os testes Testes Gonadal Hormones cutâneos/séricos para antigénios específicos e a avaliação do nível de C4. A abordagem depende do mecanismo subjacente, mas pode incluir tratamento para a anafilaxia, remoção de agentes agressores, anti-histamínicos, glucocorticóides e/ou tratamentos direcionados à bradicinina.

O angioedema Angioedema Angioedema is a localized, self-limited (but potentially life-threatening), nonpitting, asymmetrical edema occurring in the deep layers of the skin and mucosal tissue. The common underlying pathophysiology involves inflammatory mediators triggering significant vasodilation and increased capillary permeability. Angioedema mediado por mastócitos está tipicamente associado à urticária.
Estas etiologias não estão associadas à libertação de histamina ou à urticária.
