目的：为给临床提供肝血流阻断切肝术的解剖学基础。方法：在３７具成人尸体上解剖并观测了与肝血流阻断部位有关的结构。结果：①肝裸区深度４６．６±６．１ｍｍ，下腔静脉的膈上段长１１．７±２．４ｍｍ，外径２６．３±３．０ｍｍ，肝上段长１１．４±２．１ｍｍ，外径２７．４±５．２ｍｍ，肝下段长２７．７±６．７ｍｍ，外径为２８．１±３．８ｍｍ；②肝十二指肠韧带长４０．６±４．７ｍｍ，门静脉外径１４．０±３．４ｍｍ，肝固有动脉长２１．３±５．１ｍｍ，外径４．６±１．０ｍｍ；③膈与腹腔动脉起点间腹主动脉长２４．７±５．２ｍｍ，外径２４．５±３．１ｍｍ。结论：下腔静脉的膈上段、肝上段、肝下段、肝十二指肠韧带内结构、膈与腹腔动脉起点间腹主动脉段作为肝血流阻断的部位是可行的。
Objective: To provide clinical anatomy of hepatic blood flow blocking hepatectomy. METHODS: The structures associated with hepatic blood flow block were dissected and observed on 37 adult cadavers. Results: ① The depth of the liver bare area was 46.6 ± 6.1mm, the length of the inferior vena cava was 11.7 ± 2.4mm, the diameter was 26.3 ± 3.0mm, the length of the upper liver was 11.4 ± 2.1mm , The outer diameter of 27.4 ± 5.2mm, the length of the lower hepatic segment 27.7 ± 6.7mm, the outer diameter of 28.1 ± 3.8mm; ② hepatoduodenal ligament length 40.6 ± 4.7mm, portal vein 14.0 ± 3.4mm in diameter, 21.3 ± 5.1mm in native hepatic artery and 4.6 ± 1.0mm in outer diameter. The abdominal aorta between the diaphragm and the beginning of celiac artery was 24.7 ± 5.2mm , Outer diameter 24.5 ± 3.1mm. CONCLUSIONS: It is feasible for the inferior vena cava in the upper diaphragm, the upper hepatic segment, the lower hepatic segment, the hepaticoduodenal ligament, the abdominal aorta segment between the diaphragm and the beginning of the celiac artery to block the hepatic blood flow.
