ABSTRACT
Angioedema is an asymmetric non-pitting oedema on face, lips, tongue and mucous membranes; any delay in diagnosis and treatment can be fatal. Treatment with lisinopril as an angiotensin converting enzyme (ACE) inhibitor, can be a reason of angioedema. Here we report a case who developed oral-facial edema four years after using lisinopril/hydrochlorothiazide. Laryngeal oedema is a main cause of death in angioedema. The treatment of choice in angioedema including fresh frozen plasma, C1 inhibitor concentrations and BRK-2 antagonists (bradykinin B2 receptor antagonists) were used. In this case; a 77 years old female patient suffering from hypertension was considered. This patient was suffering two days from swelling on her face and neck. Non- allergic angioedema was distinguished in five major forms; acquired (AAO), hereditary (HAE), renin-angiotensin-aldosterone system (RAAS) blocker-dependent, pseudoallergic angioedema (PAS) and an idiopathic angioedema (IAO). She was admitted to our clinic with the diagnosis of hereditary angioedema. Patient had skin edema and life threatening laryngeal edema. In emergency department treatment was started using intravenous methylprednisolone, diphenydramine as well as inhaled and subcutaneous epinephrine simultaneously. Despite the initial treatment, the patient died due to the insufficient respiration and cardiac arrest. The patient has no history of kidney disease.
