Pseudoaneurysm is a known complication of pancreatitis associated with significant mortality and morbidity. Imaging plays an important role in the diagnosis and management. Computed tomography (CT) helps localize the lesion and the severity of the background pancreatitis but digital subtraction angiography with coil embolization is recommended to avoid bleeding and inadvertent surgery. However, in cases where angiographic coil embolization is not feasible due to technical reasons, thrombin injection via CT or ultrasound guidance remains a viable option and often described in literature. In this series, effort has been made to highlight the role of endoscopic ultrasound guided thrombin instillation especially in patients with poorly visualized pseudoaneurysm on ultrasound thereby avoiding surgery and the associated mortality and morbidity.
假性动脉瘤是胰腺炎的一种已知并发症，与显著的死亡率和发病率相关。影像学在诊断和管理中起着重要作用。计算机断层扫描（CT）有助于定位病变以及背景胰腺炎的严重程度，但推荐采用数字减影血管造影联合弹簧圈栓塞术以避免出血和意外手术。然而，在因技术原因无法进行血管造影弹簧圈栓塞术的情况下，通过CT或超声引导注射凝血酶仍然是一种可行的选择，并且在文献中经常有所描述。在本系列研究中，已努力突出内镜超声引导下注射凝血酶的作用，尤其是在超声下假性动脉瘤显示不清的患者中，从而避免手术及相关的死亡率和发病率。
