Anatomical hepatectomy was successfully performed in a patient with situs inversus totalis (SIT) and right-sided round ligament (RSRL). Normalized imaging and standardized terminology were crucial for surgical precision in this rare case.
Area of Science:
- Hepatobiliary Surgery
- Surgical Anatomy
- Congenital Anomalies
Background:
- Situs inversus totalis (SIT) involves mirror-image reversal of thoracoabdominal viscera.
- Right-sided round ligament (RSRL) is a rare anomaly associated with hepatic vasculature.
- The coexistence of SIT and RSRL is exceptionally rare and complicates hepatectomy.
