Coeliac artery stenosis (CAS) is rarely of consequence owing to rich collateral supply from the superior mesenteric artery via the pancreatic head. Pancreaticoduodenectomy (PD) in CAS disrupts these collaterals, and places the liver, stomach and spleen at risk of ischaemia. A 56-year-old man presented with a 3-week history of obstructive jaundice. Computed tomography revealed an operable periampullary tumour with CAS due to compression by the median arcuate ligament with multiple collaterals in the pancreatic head and a prominent gastroduodenal artery (GDA). Following unsuccessful coeliac axis endovascular stenting, a PD was performed. Intraoperative median arcuate ligament release failed to restore good flow in the common hepatic artery (CHA) and splenic artery (SpA) A decision was made to use the left gastric artery (LGA) for arterial reconstruction, disconnect it from the stomach with its origin intact and anastomose it to the supracoeliac aorta. Doppler ultrasonography with a GDA clamp confirmed good filling of the CHA and SpA via the LGA. The GDA was ligated and the PD completed. The patient had an uneventful recovery except for a biochemical pancreatic leak and was discharged on day 10. CAS during PD (confirmed by a decrease in CHA flow with a GDA clamp) requires an additional procedure to restore blood flow to the liver, stomach and spleen. Anastomosing the LGA to the supracoeliac aorta is a simple reconstruction technique for achieving this.
由于肠系膜上动脉经胰头提供丰富的侧支循环,腹腔干狭窄(CAS)很少产生后果。在CAS患者中进行胰十二指肠切除术(PD)会破坏这些侧支循环,使肝脏、胃和脾脏面临缺血风险。一名56岁男性,有3周的梗阻性黄疸病史。计算机断层扫描显示可手术切除的壶腹周围肿瘤合并CAS,原因是中弓状韧带压迫,胰头有多个侧支循环,胃十二指肠动脉(GDA)明显增粗。在腹腔干血管内支架置入术失败后,进行了PD。术中中弓状韧带松解未能恢复肝总动脉(CHA)和脾动脉(SpA)的良好血流。决定使用胃左动脉(LGA)进行动脉重建,在其起始部保持完整的情况下将其与胃分离,并将其与腹腔干上方的主动脉吻合。用GDA夹闭时进行多普勒超声检查证实通过LGA可使CHA和SpA良好充盈。结扎GDA并完成PD。除生化性胰漏外,患者恢复顺利,于第10天出院。PD期间的CAS(通过用GDA夹闭时CHA血流减少证实)需要额外的手术来恢复肝脏、胃和脾脏的血流。将LGA与腹腔干上方的主动脉吻合是实现这一目的的一种简单重建技术。
