Abstract

This study highlights the role of intraoperative sonography (IOS) using a high-frequency transducer in living donor liver transplantation (LDLT) with modified right-lobe grafts. IOS is pivotal for the real-time assessment of vascular patency and anastomotic integrity, providing crucial insights into hepatic artery, portal vein, and hepatic vein configurations. The technique's high spatial resolution allows for the early detection of potential vascular complications, which are significant predictors of postoperative outcomes. Through detailed illustrations of vascular anastomoses and hemodynamics, this article discusses technical and anatomical considerations of IOS and demonstrates its effectiveness in screening and managing vascular complications in LDLT, thereby enhancing surgical precision and patient safety.
