目的：阐明冠状韧带下层解剖学特点，并为医学影像提供解剖学的基础。材料和方法：大体解剖50例肝和30具男性成年尸体断面标本，间距为1．22CM连续的横断面标本。结果：1．腹膜从肝反拆至右肾和右肾上腺，形成肝肾韧带。文献和教科书所指的冠状韧带下层，实际上是冠状韧带下层的肝肾韧带这一部份。2．肝肾韧带在肝的右缘与冠状韧带上层相互移行为右三角韧带。肝肾韧带在下腔静脉的右缘越过其前面达左缘后反折至膈，形成冠状韧带左层。3．冠状韧带左层沿下腔静脉左缘向上达膈顶后进入静脉韧带裂与小网膜后层相续连。4．100％冠状韧带左层与冠状韧带上层、镰状韧带和肝尾状叶在第二肝门平面同步出现；但在第一肝门平面不同步消失。5．冠状韧带左层和右三角韧带出现或消失在邻近第一肝门平面。在第二肝门和第一肝门平面之间的横断层面上观察到的“冠状韧带下层”，就是冠状韧带左层，冠状韧带上层与冠状韧带左层之间为肝裸区（腹膜外间隙）。在右三角韧带出现的断层，可见冠状韧带下层的两个组成成份-肝肾韧带和冠状韧带左层；在右三角韧带和肝肾韧带之间是肝肾隐窝，在肝肾韧带与冠状韧带下层之间是肝裸区。6．本文还结合影像学讨论了冠状韧带左层的临床应用意义。
OBJECTIVE: To elucidate the anatomic features of the coronal ligament and to provide an anatomical basis for medical imaging. MATERIALS AND METHODS: The anatomical specimens of 50 adult and 30 adult male cadavers were dissected and their cross-sectional area was 1.22CM. Results: 1. Peritoneal anti-demolition from the liver to the right kidney and right adrenal, the formation of liver and kidney ligaments. The lower layers of the coronal ligaments referred to in the literature and textbooks are actually the parts of the liver and kidney ligaments below the coronal ligaments. 2. Liver and kidney ligaments in the right edge of the liver and the upper coronary ligament shift to the right triangle ligament. Liver and kidney ligaments over the right edge of the inferior vena cava in front of its left edge after the fold to the diaphragm, the formation of the left coronary ligament. 3. Left coronal ligament along the left inferior vena cava up to the top of the diaphragm after entering the venous ligament rupture with the posterior layer of parietal continuous with. 4. 100% of the left coronary ligament and the upper coronary ligament, sickle ligament and caudate lobe in the second hepatic plane simultaneously appear; but in the first hepatic plane disappear out of sync. 5. Left coronal ligament and right triangle ligament appear or disappear in the vicinity of the first hepatic portal plane. The “coronal ligament lower” observed on the transverse plane between the second hepatic portal and the first hepatic portal plane is the left coronoid ligament, the supranuclear area between the superior coronoid ligament and the left coronoid ligament (extraperitoneal space ). The fault appears in the right triangle ligament, showing the lower part of the coronal ligament of the two components - the liver and kidney ligament and the left coronary ligament; in the right triangle ligament and liver and kidney ligaments between the liver and kidney crypts, in the liver and kidney ligaments and coronary ligaments Between the lower is the liver naked area. 6. This article also discusses the clinical application of the left coronary ligament with imaging.
