Purpose: To evaluate the safety and long-term clinical outcomes of stent-graft placement to stop hepatic artery bleeding after pancreaticobiliary surgery.
Materials and methods: Outcomes were retrospectively evaluated in 61 patients (50 men, 11 women; mean age, 63) who underwent stent-graft placement for delayed arterial bleeding (after 24 hours) after pancreaticobiliary surgery from 2006 to 2023. Bleeding sites included the gastroduodenal artery stump (n=54), the common or proper hepatic artery (n=5), and right hepatic artery (n=2). The stent-graft used were Viabahn (n = 27), ComVi (n = 11), Jostent (n = 3), Covera (n = 11), and LifeStream (n = 7) vascular covered stents. Technical and clinical success, and adverse event (AE) were evaluated. After stent-graft placement, overall survival (OS), hemorrhage-free survival (HFS), and stent patency were evaluated.
Results: The technical and clinical success rates of stent-graft placement were 97% and 93%, respectively. The severe AE rate was 12% and was significantly higher in patients who underwent pylorus-sacrificing than pylorus-preserving surgery (P = 0.001). None of the severe AEs were associated with patient mortality. Median OS after stent-graft placement was 854 days and median HFS was 822 days. The 1-, 3-, 5-, and 10-year stent patency rates were 87%, 84%, 79%, and 72%, respectively.
Conclusion: Stent-graft placement was safe and provided long-term control of hepatic artery bleeding after pancreaticobiliary surgery.
