肝胆损伤是胆囊切除术最常见的并发症之一，常伴有动脉损伤。由于包括副肝管在内的肝管存在多种解剖变异，因此在胆囊切除术中不仅要考虑肝管的解剖位置，还要考虑副肝管的解剖位置。然而，AHD和肝动脉之间的地形关系仍然知之甚少。在目前的研究中，我们发现，AHD中观察到7的59（11.9%）的尸体。7具尸体中有6具为单AHD，1具为双AHD。在这些病例中，右侧AHD从肝的前内侧段穿透实质出现，而左侧AHD直接从尾状叶的前部出现。右AHD走行在右肝动脉前方，而左AHD走行在肝动脉后方。AHD和肝动脉系统之间的地形关系，从而扭转的情况下，右和左AHD。
Hepatic biliary injury is one of the most common complications in cholecystectomy and is frequently accompanied by arterial injuries. Because there are several anatomical variations of the hepatic ducts, including the accessory hepatic ducts (AHDs), it is important to consider not only the anatomical position of the hepatic ducts but also those of the AHDs in cholecystectomy. However, the topographical relationships between the AHDs and the hepatic arteries are still poorly understood. In the present study we show that AHDs were observed in 7 out of 59 (11.9%) of the cadavers. There was a single AHD in the 6 out of the 7 cadavers and double AHDs in one. In these cases, the right AHDs emerged from the anterior medial segment of the liver piercing the parenchyma, while the left AHDs emerged directly from the anterior part of the caudate lobe. The right AHDs ran anterior to the right hepatic artery, while the left AHDs ran posterior to the hepatic arteries. The topographical relationship between the AHD and the hepatic artery system was thus reversed in the cases of the right and the left AHDs.
