BACKGROUND Percutaneous coronary intervention(PCI) is extensively used to treat acute coronary syndromes(ACS).Acute mesenteric ischemia is a life-threatening disease if untreated.CASE SUMMARY An 81-year-old female presented with 3 d of lethargy and 1 d of dyspnea.On November 16,2021,the patient developed a coma.Her oxygen saturation dropped to 70%-80%,the patient was admitted to the intensive care unit for further treatment.Chest computed tomography(CT) showed chronic bronchitis,emphysema,and multiple lung infections.Abdominal CT scan showed no obvious abnormalities,but have severely calcified abdominal vessels.The patient received assisted ventilation,and vasoactive,and anti-infection drugs.Troponin level was elevated.Since the patient was in a coma,it could not be determined whether she had chest pain.The cardiologist assumed that the patient had developed ACS;therefore,the patient underwent PCI via the left femoral artery approach,and no obvious abnormalities were found in the left and right coronary arteries.On the second postoperative day,the patient presented with abdominal distension and decreased bowel sounds;constipation was considered and a glycerin enema was administered.On day 4,the patient suddenly lost consciousness,and had decreased blood pressure,abdominal wall swelling with increased tension,and absence of bowel sounds.An urgent abdominal CT scan revealed gas in her hepatic portal system with extensive bowel wall necrosis.The patient died on day 5 due to intractable shock.CONCLUSION The potential serious complications in patients undergoing PCI,especially the patients who are hemodynamically unstable and have severely calcified abdominal vessels,should all be considered.
