目的:研究镰状韧带的形态、血供及其在腹腔镜肝脏外科的意义。方法:用腹腔镜观察２０例活体,３０例动脉灌注乳胶标本及５例血管透明标本,研究镰状韧带的解剖结构、血供来源、血管分布及侧支吻合。结果:镰状韧带由双侧腹膜合成,长为(８．３±１．６)ｃｍ,最宽处为(４．９± ０．８)ｃｍ,最窄处为(１．１±０．３)ｃｍ;血供主要来自左膈下动脉和肝中动脉,二者于镰状韧带肝缘形成血管弓,并发出６~１２支分布于镰状韧带;静脉不与动脉伴行,回流至左膈下静脉。结论:镰状韧带的血管与多条血管吻合,是肝脏侧支循环的重要途径。镰状韧带是腹腔镜肝脏外科的重要标志和入路。
Objective: To study the morphology and blood supply of sickle ligament and its significance in laparoscopic liver surgery. Methods: Twenty cases of living body, 30 cases of arterial instillation and 5 cases of transparent vascular specimens were observed by laparoscopy. The anatomical structure, blood supply, blood vessel distribution and side branch anastomosis of sickle ligament were studied. Results: The sickle ligament was synthesized by bilateral peritoneum with length of (8.3 ± 1.6) cm, (4.9 ± 0.8) cm at the widest point and (1.1 ± 0) at the narrowest point. 3) cm; blood supply mainly from the left subphrenic artery and middle hepatic artery, the two formed in the falx ligament of the hepatic margin of the vascular arch, and issued 6 to 12 in the sickle ligament; vein does not accompany the artery, back to Left subphrenic vein. Conclusion: The blood vessels of sickle ligament are anastomosed with multiple blood vessels, which is an important pathway of collateral circulation in the liver. Sickle-shaped ligament is an important sign and route of laparoscopic liver surgery.
