Core Tip

Core Tip: Right-sided ligamentum teres (RSLT) is often associated with intrahepatic anomalies. Most studies hypothesis that left-sided gallbladder (LGB) must exist with RSLT. However, our exploration reveals that RSLT doesn't consistently coexist with LGB. Our analysis further suggests that RSLT can predict poral venous anomalies (PVAs) independently while the gallbladder location does not serve as a sufficient predictor. Therefore, operators, interventional radiologists or interventional gastroenterologists should not use the gallbladder location as an alternative of ligamentum teres location for PVAs prediction.
