Icatibant as a Potential Treatment of Life-Threatening Alteplase-Induced Angioedema.

Severe orolingual angioedema is a life-threatening complication of alteplase treatment for acute ischemic stroke that occurs during alteplase infusion or in the first 2 hours afterward. Currently, there are no proven therapies, although glucocorticoids, antihistamines, and adrenaline are sometimes used. Intubation is required if significant airway compromise supervenes. The incidence is .2%-5.1%, and risk factors include treatment with angiotensin-converting enzyme inhibitors and total insular infarcts. Here we report a case of alteplase-induced severe angioedema, which resolved briskly following icatibant treatment.
