Abstract
The mortality rate of patients with ruptured pancreaticoduodenal artery aneurysms is high; therefore, it is recommended to treat pancreaticoduodenal artery aneurysms regardless of their size. In small pancreaticoduodenal artery aneurysms, however, identification of the access route on two-dimensional arteriography is sometimes difficult because of the superimposition of many hypertrophied branches of pancreaticoduodenal arteries on the aneurysm. We report two cases of ruptured pancreaticoduodenal artery aneurysm embolized successfully with metallic coils, assisted by automated feeder-detection software using cone-beam computed tomography data. This new technology may reduce physicians’ workload during the procedure.
