The left triangular ligament of the liver was studied in 42 Chinese adult male cadavers and 50 Canadian adult cadavers. The free edge of the left triangular ligament was examined histologically in 37 of the Chinese and all 50 of the Canadian cadavers. The average length of the left triangular ligament in the 42 Chinese was 13.9 cm and 11.5 cm in the 50 Canadian. The Canadian sample was composed of 24 adult female cadavers with an average length of 10.7 cm and of 26 adult male cadavers with an average length of 12.3 cm. In a previous study (1980) of 58 Chinese adult male cadavers, the average length of the left triangular ligament was 12.7 cm. This resulted in an average length of 13.2 cm for the 100 Chinese cadavers. These findings greatly exceed the lengths given in the textbooks, and there is no significant difference between the male Chinese and Canadian cadavers. It was found that almost all the left triangular ligaments were attached to the superior surface of the left lobe of the liver. The left suprahepatic space was subdivided by this ligament into anterior and posterior spaces. Each of the left triangular ligaments had a long free edge which extended from the lateral extremity of the left lobe of the liver to the diaphragm. Histological examination of the free edges revealed the presence of blood vessels in all of the 37 Chinese suitable for study and the 50 Canadian cadavers.(ABSTRACT TRUNCATED AT 250 WORDS)
对42具中国成年男性尸体和50具加拿大成年尸体的肝左三角韧带进行了研究。对37具中国尸体和所有50具加拿大尸体的肝左三角韧带游离缘进行了组织学检查。42具中国尸体的肝左三角韧带平均长度为13.9厘米，50具加拿大尸体的为11.5厘米。加拿大样本包括24具成年女性尸体，平均长度为10.7厘米，以及26具成年男性尸体，平均长度为12.3厘米。在之前（1980年）对58具中国成年男性尸体的研究中，肝左三角韧带的平均长度为12.7厘米。这使得100具中国尸体的平均长度为13.2厘米。这些结果大大超过了教科书给出的长度，并且中国男性尸体和加拿大尸体之间没有显著差异。发现几乎所有肝左三角韧带都附着于肝左叶的上表面。肝左膈上间隙被该韧带分为前间隙和后间隙。每条肝左三角韧带都有一个长的游离缘，从肝左叶的外侧端延伸至膈肌。对游离缘的组织学检查显示，在所有37具适合研究的中国尸体和50具加拿大尸体中均存在血管。（摘要截取自250词）
