Treatment Strategies for a Pancreaticoduodenal Artery Aneurysm with or without a Celiac Trunk Occlusive Lesion.

OBJECTIVES A true pancreaticoduodenal artery aneurysm (PDAA) is a rare disease, and has some unique characteristics: a high rupture risk and a strong correlation with celiac trunk stenotic lesions (CTSL). We showed here that our treatment strategy for PDAA. MATERIALS AND METHODS Seven consecutive patients with PDAA at our institution from 1998 to 2011 were retrospectively reviewed. Of the 7 patients, five were male and two were female, with a mean age of 55 ± 9.7 years. Three aneurysms were diagnosed incidentally, and the remaining four ruptured. The locations of the aneurysm were the anterior superior pancreaticoduodenal artery (ASPDA) in 3 patients and the inferior pancreaticoduodenal artery (IPDA) in four. CTSL found 3 patients in the IPDA. RESULTS Of four ruptured patients, emergency catheter coil embolization was performed in three, and a simple ligation was performed in one. Three patients with non-ruptured aneurysms in the IPDA with a CTSL underwent direct aneurysm resection with arterial reconstruction. Six patients were successfully treated without complications or the appearance of new aneurysms during the follow-up period. CONCLUSION The treatment strategy for PDAA should be selected by the site of the aneurysm, the patients' condition, and the anatomical situation. A hybrid treatment could be considered a beneficial option for a CTSL.
