Abstract

Pancreaticoduodenal artery pseudoaneurysm is one kind of rare splanchnic artery aneurysm. Hemorrhage from the lesion could be life-threatening. We present a case which color Doppler ultrasound and computed tomography angiography (CTA) only showed pancreatic pseudocyst on the background of chronic pancreatitis at first, but contrast-enhanced ultrasound detected blood flow in the pseudocyst and a pancreaticoduodenal artery pseudoaneurysm was worked up several days after. Finally, the pancreaticoduodenal artery pseudoaneurysm was confirmed by digital subtracted angiography. It might suggest the potential advantage of contrast-enhanced ultrasound in evaluating this kind of disease in comparison of CTA.

摘要

胰十二指肠动脉假性动脉瘤是一种罕见的内脏动脉动脉瘤。病变出血可能危及生命。我们报告一例病例，最初彩色多普勒超声和计算机断层血管造影（CTA）仅显示慢性胰腺炎背景下的胰腺假性囊肿，但增强超声检测到假性囊肿内血流，几天后诊断为胰十二指肠动脉假性动脉瘤。最终，数字减影血管造影证实了胰十二指肠动脉假性动脉瘤的存在。与 CTA 相比，增强超声在评估此类疾病方面可能具有潜在优势。
