Abstract

A 64-year-old man presented with epigastric pain and underwent contrast-enhanced computed tomography. Ruptured aneurysm of the inferior pancreaticoduodenal artery was diagnosed. TAE was successfully accomplished using coils, but vomiting appeared 9 days later. Duodenal stenosis was diagnosed from contrast-enhanced computed tomography and upper gastrointestinal endoscopy and was attributed to edematous changes in the duodenum. Conservative management led to successful recovery and discharge.

(A) Contrast-enhanced CT shows retroperitoneal hematoma (arrows). (B) Coronal contrast-enhanced CT shows a 4-mm aneurysm on the inferior pancreaticoduodenal artery (IPDA) (arrow). Rupture of an aneurysm of the IPDA is therefore diagnosed.

(A) Angiography shows an aneurysm of the IPDA (arrow). Transcatheter arterial embolization (TAE) is then performed using coils. (B) After TAE, the aneurysm is no longer apparent.

Fig. 3
Contrast-enhanced CT the day after TAE shows enhancement of the duodenum (arrows), and no intestinal ischemia is considered present.
Fig 4
Fig. 4
(A) The patient complained of vomiting 9 days after TAE. CT shows that the hematoma has shrunk compared to the size before TAE (arrows). (B) However, coronal-section CT reveals expansion of the stomach (arrows) and stenosis of the duodenum is suspected. (C) Upper gastrointestinal endoscopy shows duodenal stenosis due to edematous changes. Conservative management is initiated.

Fig. 5
Upper gastrointestinal endoscopy 41 days after TAE reveals improvement of duodenal stenosis. The patient continued to do well without any complication and was discharged from the hospital.
