BACKGROUND: Indocyanine green (ICG) video angiography has been widely used in cerebrovascular surgery. ICG injection is generally safe, with a low incidence of complications. ICG-related anaphylactic reactions during neurosurgery have been rarely reported. We report the cases of 2 patients who had experienced anaphylactic shock in response to intravenous ICG injection (DID Indocyanine Green [Dongindang, Inc., Gyeonggi-do, Republic of Korea]) during intracranial aneurysm (IA) surgery. CASE DESCRIPTION: The first patient, a 69-year-old woman with an unruptured IA, had been undergoing clipping surgery under general anesthesia. Immediately after ICG injection, her blood pressure suddenly decreased from 140/80 mm Hg to 50/30 mm Hg and she developed a skin rash on her abdomen and all extremities. Chest compression was initiated, and her vital signs gradually recovered to their pre-ICG levels within 10 minutes. The second patient was a 58-year-old woman with an unruptured IA who had been undergoing clipping surgery. After ICG injection, her blood pressure had decreased from 130/80 rum Hg to 60/40 mm Hg, and a rash-like skin lesion was observed on her abdomen. After intravenous injection of norepinephrine and dexamethasone, her blood pressure recovered to its pre-ICG level within 30 minutes and remained stable thereafter. The postoperative ICG skin provocation test findings were positive for both patients; however, only 1 patient showed markedly increased serum tryp-tase levels. CONCLUSION: Despite the rarity of ICG-related anaphylaxis, clinicians should be aware of this unexpected, but potentially life-threatening, drug reaction in patients undergoing cerebrovascular surgery.
