摘要
解剖观测５７例成人尸体标本，结果表明：肝圆韧带自脐切迹延伸至门静脉左于囊部，可分为腱膜下段、游离段和裂隙段三段，各段长度分别为６．２±２．２．７．１±１．８，３．９±０．７ｃｍ。在成人，肝回韧带为一开放性结构，各段均可见残腔，游离段和裂隙段内残腔常呈连续性腔隙，长度达８．９±２．１ｃｍ。肝圆韧带管壁可分为内膜、中膜、外膜三层，主要由纤维结缔组织构成。肝圆韧带由腱膜下段向游离段和裂隙段过渡过程中，外径逐渐增粗，管壁厚度及残腔管径逐渐增大。肝圆韧带紧邻胆道，易于游离和取材，是修复胆道缺损较好的自体生物材料，且以游离段为适宜。肝圆韧带修复胆道缺损已在临床应用１２例，取得满意疗效。
ased on the dissections of 57 adult specimens,The
ligamentum teres hepatis(LTH)fromumbilicus to the left branch of
portal vein,can be divided into three portions,i.e.
subaponeurotic,free and fissure portions. The length of each portion
is 6.2±2.2cm,7.1±1 8 cm and 3.9±0.7cm. In adult,The LTH is a
patent structure with lumina inside,The lumina in the free and
fissureportions are continuous of 8.9±2.1 cm in length.The wall of
the LTH is in three layers(intima,media and adventitia)of mainly
consisted of fibrous connective tissue.。 The size and thickness
ofthe LTH,as well as the diameter of the lumina increase gradually
from the subaponeurotic portionto the fissure part. The LTH could be
easily freed and used as an autogenous graft for repairing ofbile
duct defect. The free portion takes the priority in the operation,
Satisfactory results have beenachieved in 12 cases of clinical
applications.
