Abstract
An 83-year-old woman was brought into our hospital because of dyspnea and thoracoabdominal pain. Initially, she was suspected to have gallbladder carcinoma with hemorrhage by physical/blood biochemical findings, abdominal CT and MRI scans. As bleeding stopped spontaneously and she was elderly and had dementia, we decided to follow her clinical course.
Thereafter she had recurrent bouts of pain of the thoracoabdominal region and tarry stool. Another abdominal CT scan revealed hemobilia and an aneurysm of the cystic artery. We assessed that the bleeding might be originated from the aneurysm of the cystic artery. After embolization of the cystic artery for the aneurysm, laparoscopic cholecystectomy was carried out. Histologically, the gallbladder was diagnosed to develop xanthogranulomatous cholecystitis, and the aneurysm of the cystic artery was pseudoaneurysm.
We performed laparoscopic cholecystectomy safely for aneurysm of the cystic artery following arterial embolization.
