Severe hypotension and postoperative cardiac arrest caused by 5-aminolevulinic acid: a case report.

Background: Although 5-aminolevulinic acid is useful for the photodynamic diagnosis of bladder tumors, it often causes severe intraoperative hypotension. We report a case of postoperative cardiac arrest in addition to severe intraoperative hypotension, probably owing to the use of 5-aminolevulinic acid.

Case Presentation: An 81-year-old Japanese man was scheduled to undergo transurethral resection of bladder tumor.
