Vascular complications after liver transplantation – HAT, HVOO, and PVT – though infrequent, demand a high index of suspicion and aggressive management. Early Doppler ultrasound monitoring and prompt imaging are essential to detect these complications in their nascent stages. Advances in surgical techniques and interventional radiology have significantly improved outcomes: for example, timely IR procedures now salvage many grafts that previously would have been lost. Multidisciplinary care, involving transplant surgeons, hepatologists, interventional radiologists, and intensive care specialists, is required to optimize results. Moreover, preventive strategies – from meticulous surgical anastomoses to prophylactic anticoagulation in high-risk patients – are increasingly recognized as crucial in minimizing the incidence of these complications. By understanding the incidence, risk factors, and presentations of HAT, HVOO, and PVT, transplant teams can ensure early diagnosis and tailored interventions, thereby improving graft survival and patient outcomes in liver transplantation.
