Pseudoaneurysms due to chronic pancreatitis can be a source of major gastrointestinal (GI) hemorrhage. Computed tomography (CT) is the primary diagnostic imaging modality for pancreatic pseudocysts associated with GI bleeding. Pseudoaneurysms and associated GI bleeding can be diagnosed and embolized with transcatheter techniques once the arterial anatomy is defined. CT is a useful modality for follow-up examination of the pseudocyst; the findings must be correlated with other procedures performed on these patients. On follow-up studies, contrast medium retained in the pseudocyst after embolization may falsely signal persistent bleeding into the pseudocyst.
慢性胰腺炎所致假性动脉瘤可能是严重胃肠道（GI）出血的一个来源。计算机断层扫描（CT）是用于诊断与GI出血相关的胰腺假性囊肿的主要影像学检查方法。一旦明确动脉解剖结构，假性动脉瘤及相关的GI出血可用经导管技术进行诊断和栓塞。CT对于假性囊肿的随访检查是一种有用的方法；检查结果必须与对这些患者进行的其他检查相关联。在随访研究中，栓塞后残留在假性囊肿内的造影剂可能会错误地提示假性囊肿持续出血。
