目的评价急性胰腺炎伴假性动脉瘤的CT诊断和经导管栓塞治疗的价值。方法对18例急性胰腺炎伴假性动脉瘤患者进行腹部动脉造影和经导管栓塞治疗,回顾性分析其CT、血管造影和临床资料,观察假性动脉瘤的部位及止血效果。结果18例患者CT平扫显示腹腔局限或弥漫性高密度积液,增强扫描显示假性动脉瘤,破裂处可见造影剂外溢。血管造影显示假性动脉瘤22个,其中20个有活动性出血征象,均采用弹簧圈成功栓塞,18个假性动脉瘤一次成功止血。结论CT检查可发现急性胰腺炎伴假性动脉瘤,经导管栓塞治疗是有效和安全的方法。
Objective To evaluate the value of CT diagnosis and transcatheter embolization in patients with acute pancreatitis and pseudoaneurysm. Methods Eighteen patients with acute pancreatitis and pseudoaneurysm were treated by abdominal arteriography and catheter embolization. CT, angiography and clinical data were retrospectively analyzed. The site of pseudoaneurysm and the hemostatic effect were observed. Results CT scan of 18 patients showed cesarean section or diffuse high-density effusion, enhanced scan showed pseudoaneurysm, and the contrast agent showed spillage at rupture. Angiography showed 22 pseudoaneurysms, of which 20 had active bleeding signs, were successfully embolized coil, 18 pseudoaneurysm a successful hemostasis. Conclusion CT examination can be found in patients with acute pancreatitis with pseudoaneurysm, transcatheter embolization is an effective and safe method.
