Coronary covered stents in the management of late-onset arterial complications post-hepato-pancreato-biliary surgery.

Purpose: To retrospectively evaluate the safety, efficacy, and late clinical outcome of coronary covered stent placement for the treatment of late-onset arterial complications after hepato-pancreato-biliary surgery.

Materials And Methods: Consecutive patients presenting with post-hepato-pancreato-biliary surgery-related arterial lesions and subsequently treated with a covered coronary stent in the authors institution between January 2012 and November 2021 were included. Primary endpoints were technical and clinical success; secondary endpoints were covered stent patency and end-organ perfusion of the affected artery.

Results: The study included 22 patients (13 men and 9 women) with a mean age of 67 years ± 9.6 years. Initial surgery included pancreaticoduodenectomy (n = 15; 68%), liver transplantation (n = 2; 9%), left hepatectomy (n = 1; 5%), bile duct resection (n = 1; 5%), hepatogastrostomy (n = 1; 5%), and segmental enterectomy (n = 1; 5%). Technically, coronary covered stents were successfully placed in n = 22 patients (100%) without immediate complication. Definitive bleeding control was observed in n = 18 patients (81.1%) with recurrent bleeding within 30 days postintervention in n = 5 patients (23%). No ischemic liver or biliary complications occurred during the follow-up period. The 30-day mortality rate was 0%.

Conclusion: Coronary covered stents are a safe and efficient treatment option in most of the patients presenting with late-onset postoperative arterial injuries following hepato-pancreato-biliary surgery and are associated with an acceptable recurrent bleeding rate and no late, ischemic, parenchymal complications.
