Identify the Arc of Riolan artery as a potential sole pathway for lymphatic spread in advanced splenic flexure cancer.
Analysis of anatomical pathways associated with splenic flexure cancer.
Identification of lymphatic drainage routes related to the Arc of Riolan.
Recommendations for surgical interventions involving nodal dissection along the artery.
The Arc of Riolan may serve as a critical pathway for metastasis in certain cases of splenic flexure cancer.
Careful nodal dissection along this vessel could improve oncologic outcomes.
Abstract
Surgeons should recognize AoR as a possible isolated metastatic pathway and perform thorough nodal dissection along this vessel when present to ensure optimal oncologic outcomes.
