Chronic pancreatitis is known to cause vascular disorders including pseudoaneurysm of peripancreatic arteries. Although the incidence of pseudoaneurysms due to pancreatitis detected by angiography has been reported as high as 10% in western literature, they are still considered rare in Japan. We reported two cases of pseudoaneurysm caused by chronic pancreatitis, one in splenic artery and the other in gastroduodenal artery, successfully treated by embolization. The embolizations were performed by occluding proximal splenic artery for splenic arterial aneurysm and gastroduodenal artery distal and proximal to the orifice for the aneurysm of gastroduodenal artery with stainless steel coils. Since the surgical therapy has high mortality rate, we consider transcatheter embolization is the treatment of choice for pseudoaneurysms caused by chronic pancreatitis.
已知慢性胰腺炎会引发血管疾病，包括胰周动脉假性动脉瘤。尽管西方文献报道血管造影检测出的胰腺炎所致假性动脉瘤发病率高达10%，但在日本仍被认为较为罕见。我们报告了两例由慢性胰腺炎引起的假性动脉瘤病例，一例位于脾动脉，另一例位于胃十二指肠动脉，均通过栓塞成功治疗。对于脾动脉动脉瘤，通过闭塞脾动脉近端进行栓塞；对于胃十二指肠动脉瘤，通过不锈钢圈闭塞动脉瘤开口远端和近端的胃十二指肠动脉。由于手术治疗死亡率高，我们认为经导管栓塞是慢性胰腺炎所致假性动脉瘤的首选治疗方法。
