[Postoperative takotsubo cardiomyopathy caused by an ectopic paraganglinoma after gastric submucosal tumor resection].
We encountered an 80-year-old woman with an ectopic paraganglioma of the bladder who developed takotsubo cardiomyopathy after gastric submucosal resection performed for an unrelated tumor. Preoperative blood pressure control was not necessary despite the presence of the noradrenaline-producing paraganglioma However, the patient developed severe intraoperative hypotension, and thereafter manifested takotsubo cardiomyopathy after the operation. Perioperative stress and catecholamine production by the bladder paraganglioma were considered to have induced the takotsubo cardiomyopathy. In retrospect, considering the influence of potential catecholamine release from the paraganglioma, we should probably have scheduled preferential treatment of the bladder paraganglioma and strictly monitored the perioperative hemodynamics.
