Summary
Hepatic artery thrombosis (HAT) and stenosis (HAS) after liver transplantation (LTx) are serious complications, often caused by surgical technique. These arterial issues significantly increase patient morbidity and mortality.
Area of Science:
- Vascular Surgery
- Transplant Surgery
- Gastroenterology
Context:
- Arterial complications, primarily hepatic artery thrombosis (HAT) and stenosis (HAS), are significant causes of morbidity and mortality following liver transplantation (LTx).
- These vascular disturbances are frequently attributed to technical aspects of the surgical procedure.
Purpose:
- To determine the incidence and clinical consequences of hepatic artery thrombosis (HAT) and hepatic artery stenosis (HAS) in patients undergoing liver transplantation (LTx).
Summary:
- This retrospective study analyzed 246 LTx in 203 patients, identifying HAT in 22 and HAS in 11.
- HAT led to retransplantation in many cases with low survival rates, and was associated with a high incidence of biliary complications (45%) and sepsis-related death.
- HAS also resulted in significant morbidity, requiring surgical revision and contributing to sepsis-related mortality.
Impact:
- Arterial complications post-LTx are life-threatening and predominantly technical in origin.
- Meticulous surgical technique during graft harvesting, preparation, and transplantation is crucial to minimize the risk of these vascular complications.
- Early detection and management of HAT and HAS are vital for improving patient outcomes after liver transplantation.
