Abstract:
Endoscopic ultrasonography-guided hepaticogastrostomy (EUS-HGS) has emerged as an alternative drainage technique for patients with malignant biliary obstruction. However, few reports have discussed the occurrence of late-onset rupture of hepatic artery pseudoaneurysms following EUS-HGS. A recently available drill dilator equipped with a long screw segment was used in the dilation step of EUS-HGS. We highlight the potential concern that this long screw segment may increase the risk of damage to the hepatic artery, leading to late-onset life-threatening rupture of a pseudoaneurysm.
摘要:
内镜超声引导的肝胃造口术(EUS-HGS)已成为恶性胆道梗阻患者的替代引流技术。然而,很少有报道讨论EUS-HGS后肝动脉假性动脉瘤迟发性破裂的发生。在EUS-HGS的扩张步骤中使用了最近可用的装有长螺钉段的钻头扩张器。我们强调了潜在的担忧,即这个长螺钉段可能会增加肝动脉受损的风险,导致迟发性危及生命的假性动脉瘤破裂。
