Preoperative liver arterial conditioning in patients scheduled for a Mayo Clinic class Ia distal pancreatectomy: embolization or ligation?

Published:January 19, 2023DOI:



      Liver ischemia may occur during intraoperative common hepatic artery ligation in Mayo Clinic class I distal pancreatectomy with en bloc celiac axis resection (DP-CAR). Preoperative liver arterial conditioning could be used to avoid this outcome. This retrospective study compared arterial embolization (AE) or laparoscopic ligation (LL) of the common hepatic artery before class Ia DP-CAR.


      From 2014 to 2022, 18 patients were scheduled for class Ia DP-CAR after neoadjuvant FOLFIRINOX treatment. Two were excluded due to hepatic artery variation, six underwent AE, ten underwent LL.


      Two procedural complications occurred in the AE group: an incomplete dissection of the proper hepatic artery and a distal migration of coils in the right branch of the hepatic artery. Neither complication prevented surgery. The median delay between conditioning and DP-CAR was 19 days; decreased to five days in the last six patients. None required arterial reconstruction. Morbidity and 90-day mortality rates were 26.7% and 12.5%, respectively. No patient developed postoperative liver insufficiency after LL.


      Preoperative AE and LL seem comparable in averting arterial reconstruction and postoperative liver insufficiency in patients scheduled for class Ia DP-CAR. However, serious complications that may arise during AE led us to prefer the LL technique.
