Abstract:
A 52-year-old woman had undergone colectomy and adjuvant chemotherapy for stage IV cecal cancer with peritoneal dissemination and multiple metastases to the lung and liver. After two years of follow-up, she suddenly had right upper limb pain and was reffered to our hospital for treatment of acute upper limb ischemia. Enhanced CT revealed obstruction of the right brachial artery and metastatic lung cancer with pulmonary vein invasion. We performed emergency embolectomy with local anesthesia. The patient's perioperative course was uneventful. Pathological findings of the removed embolus revealed that it contained adenocarcinoma cells. We concluded that the embolus had originated from the metastatic lung cancer with pulmonary vein invasion.
