Variations in the origin, course, and branching of visceral arteries, particularly those of the celiac artery and superior mesenteric artery (SMA), are well documented in medical literature. Identifying any variation is necessary prior to abdominal surgery.
A 72-year-old male presented after a pancreatic body mass was incidentally found on abdominal computed tomography (CT). The CT revealed an anatomic anomaly of the splenic artery. The patient's splenic artery originated from his SMA rather than from his celiac artery.
Accounting for this anatomic anomaly prior to performing an open distal pancreatectomy and splenectomy was essential to the surgery's success. Ligation of the splenic vein followed by early ligation of the splenic artery allowed for minimal splenic congestion. Preoperative planning and understanding the patient's unique anatomy minimized the risk of an adverse outcome.
内脏动脉，尤其是腹腔干动脉和肠系膜上动脉（SMA）的起源、走行和分支变异在医学文献中有充分记载。在腹部手术前识别任何变异是必要的。
一名72岁男性在腹部计算机断层扫描（CT）偶然发现胰体肿物后就诊。CT显示脾动脉存在解剖异常。该患者的脾动脉起源于肠系膜上动脉而非腹腔干动脉。
在进行开放性远端胰腺切除术和脾切除术之前考虑到这种解剖异常对手术成功至关重要。先结扎脾静脉，然后尽早结扎脾动脉可使脾充血降至最低。术前规划并了解患者独特的解剖结构可将不良后果的风险降至最低。
