ABSTRACT
Hydatid cyst (HC) is a parasitic disease caused by Echinococcus granulosus and E. alveolaris. It is still a serious health problem in endemic regions. One of the common complications of HC is cyst rupture, spontaneously by external traumas or during surgical operations. Rupture of a HC can cause anaphylactic shock. Our case was a 34-year-old female who had a HC in her liver. She developed sudden hypotension, tachycardia, flushing, edema, and bronchospasm intraoperatively. We managed her with antihistamines, steroids, and supplementary fluids. After the operation, she was transferred to the ICU for further management. The trachea was extubated at the fifth hour of the operative day, and the patient was admitted to the surgical ward on the first postoperative day. In the management of anaphylactic reactions of HCs, quick diagnosis and early management are important for successful resuscitation.
