The goal of this observational study is to examine whether intrahepatic blood flow occlusion strategies during partial hepatectomy are associated with postoperative cardiac injury in patients undergoing hepatectomy. The primary questions it seeks to address are: 1. Are the intrahepatic blood flow occlusion method, the number of occlusions, and the cumulative occlusion time associated with postoperative cardiac injury? 2. How do intrahepatic blood flow occlusion, intraoperative hypotension, and postoperative cardiac injury interact? Participants will contribute their inpatient medical records, including information on medical history, surgical procedures, and anesthesia details.
