ACR Appropriateness Criteria® Imaging After Liver Transplant.

Area of Science:

• Transplant Surgery
• Radiology
• Medical Imaging

Background:

• Liver transplantation is the primary treatment for end-stage liver disease.
• Post-transplant complications, including vascular, biliary, infectious, rejection, and malignancy issues, can lead to graft failure or patient death.
• Effective imaging is crucial for early detection and management of these complications.

Purpose of the Study:

• To summarize the literature on selecting appropriate imaging modalities after liver transplantation.
• To provide guidance for various clinical scenarios, including immediate postoperative care, suspected vascular or biliary complications, and long-term surveillance.
• To establish evidence-based recommendations for post-liver transplant imaging.

Main Methods:

• Systematic review of peer-reviewed medical literature.
• Application of the American College of Radiology Appropriateness Criteria methodology.
• Utilizing the RAND/UCLA Appropriateness Method for evidence evaluation.
• Incorporation of expert opinion when literature is limited or equivocal.

Main Results:

• The document outlines imaging selection criteria for immediate postoperative assessment.
• Guidelines are provided for diagnosing suspected vascular and biliary complications post-transplant.
• Recommendations cover imaging surveillance protocols for liver transplant recipients.

Conclusions:

• Appropriate imaging selection is vital for managing liver transplant patients and improving outcomes.
• These guidelines support clinicians in optimizing diagnostic strategies for post-transplant care.
• The recommendations aim to enhance the detection and management of liver allograft complications.
