Clinical Trial: Preoperative Right Hepatic Artery Embolization for Locally Advanced Bismuth IIIb and IV Perihilar Cholangiocarcinoma

U.S., Jan. 9 -- ClinicalTrials.gov registry received information related to the study (NCT07326189) titled 'Preoperative Right Hepatic Artery Embolization for Locally Advanced Bismuth IIIb and IV Perihilar Cholangiocarcinoma' on Dec. 25, 2025.

Brief Summary: This is a prospective, multicenter, single-arm study investigating the efficacy and safety of preoperative right hepatic artery embolization (PHAE) followed by surgical resection in patients with locally advanced Bismuth IIIb or IV perihilar cholangiocarcinoma (PHCC) involving the right hepatic artery. The standard treatment for such cases is often considered unresectable due to the high risk of hepatic ischemia after arterial resection without reconstruction. This study proposes a str...
