Inferior pancreaticoduodenal artery aneurysms in association with celiac stenosis or occlusion are well described in the literature. These aneurysms are true aneurysms and develop as a result of increased flow through the pancreaticoduodenal arcades in the presence of hemodynamically significant stenosis of the celiac axis or common hepatic artery. Aneurysms may be multiple and rarely associated with aneurysms in other collateral pathways-such as the dorsal pancreatic artery or the arc of Buhler. These aneurysms may be incidentally detected or patients may present with abdominal pain or shock secondary to rupture of the aneurysms. Treatment options include surgical resection and transcatheter embolization; current literature favors the latter option. Treatment of celiac axis stenosis may be recommended in addition to treating the aneurysms; however, no formal guidelines exist on this recommendation.
文献中对与腹腔干狭窄或闭塞相关的胰十二指肠下动脉瘤已有充分描述。这些动脉瘤是真性动脉瘤,是在腹腔干或肝总动脉存在血流动力学显著狭窄的情况下,通过胰十二指肠动脉弓的血流量增加而形成的。动脉瘤可能是多发的,很少与其他侧支途径(如胰背动脉或布勒动脉弓)的动脉瘤相关。这些动脉瘤可能是偶然发现的,或者患者可能因动脉瘤破裂而出现腹痛或休克。治疗选择包括手术切除和经导管栓塞;目前的文献倾向于后一种选择。除了治疗动脉瘤外,可能还建议治疗腹腔干狭窄;然而,关于这一建议尚无正式指南。
