The cystic artery (CA) is known to exhibit variations in its origin and branching pattern. This is attributed to the developmental changes occurring in the primitive ventral splanchnic arteries. During routine dissection of a male cadaver, we observed that the CA originated from the middle hepatic artery (MHA) at a distance of about 1 cm from its origin, and the MHA originated from the right hepatic artery at a distance of 2.1 cm from its origin. The CA traversed for a distance of 1.5 cm, giving off a branch to the cystic duct. It then passed anterior to the cystic duct. The origin of the CA was located to the left of the common hepatic duct, outside the Calot's triangle. The topographical anatomy of the arterial system of the hepatobiliary region and their anomalous origin should be considered during hepatobiliary surgeries. This knowledge is also important for interventional radiologists in routine clinical practice.
胆囊动脉（CA）的起源和分支模式存在变异，这归因于原始腹脏动脉发生的发育变化。在对一名男性尸体进行常规解剖时，我们观察到 CA 距离其起源约 1 厘米处发自肝中动脉（MHA），而 MHA 距离其起源 2.1 厘米处发自右肝动脉。CA 走行 1.5 厘米，发出分支至胆囊管。然后它位于胆囊管的前方。CA 的起源位于胆总管的左侧，在 Calot 三角之外。在肝胆区域动脉系统的解剖结构及其异常起源应在肝胆手术中加以考虑。这一知识对于介入放射学家的常规临床实践也很重要。
