Summary
The hepatic ligamentum teres was investigated in 30 adult specimens. The ligament represents a fibrous remnant of the umbilical v. and a small irregular lumen still exists in the ligament in adult life. The ligament is supplied by one set of independent round ligament a. and paraumbilical vv. Since the proximal segment of the ligament is easily mobilised and since the ligamentous a. originates from the right hepatic a. near the hilum, a proximal vascularized pedicle flap of the ligamentum teres has been recommended. Surgical repair of the extrahepatic bile duct using a vascularized pedicle flap of the ligamentum teres has been carried out successfully in 12 patients.
Résumé
Le ligament rond du foie (ligament teres hepatis) a été étudié chez 30 sujets adultes. Ce ligament représente un reliquat fibreux de la veine ombilicale et une petite lumière irrégulière y persiste à l'état adulte. Il est vascularisé par une artère indépendante et des veines paraombilicales. A partir de son segment proximal, le ligament rond peut être aisément mobilisé, ainsi que l'artère du ligament rond née de l'artère hépatique droite près du hile, réalisant un lambeau pédiculisé. Une intervention chirurgicale pour réparer la voie biliaire extra-hépatique à partir de ce lambeau du ligament rond a été effectuée avec succès chez douze patients.
