The inguinal and femoral canals: A practical step-by-step approach to accurate sonographic assessment

Abstract

Ultrasonography (USG) is an accepted and reliable tool for the assessment of groin hernias.However, USG of the groin is operator dependent and challenging. The anatomy of this region is complex and the normal sonographic findings can be difficult to interpret. We describe the relevant normal anatomy of the groin relating to inguinal and femoral hernias, and describe a straightforward, reliable technique for identifying and assessing the integrity of the inguinal and femoral canals. The inferior epigastric vessels are a critical landmark for assessment of the inguinal canal and deep inguinal ring.
