Introduction: Inferior pancreatico-duodenal artery (IPDA) aneurysms are very rare and commonly associated with coeliac axis stenosis or occlusion due to atherosclerosis, thrombosis or median arcuate ligament syndrome. We present a case of a surgical repair of an IPDA aneurysm with the use of a supra-coeliac aorto-hepatic bypass with a polytetrafluoroethylene (PTFE) graft, following a failed initial attempt at an endovascular repair.
Presentation: A 75 year old female, who was under investigation for night sweats, was referred to our team with an incidental finding of a 19mm fusiform IPDA aneurysm. Initial attempt at endovascular coiling of the aneurysm was unsuccessful. Elective surgical repair involved excision of the aneurysm and to restore arterial inflow to the hepatic artery, a PTFE bypass graft was used from the supra-coeliac aorta to the hepatic artery. The patient was well 2 months following the procedure with a patent graft shown on contrast enhanced computer tomography (ceCT).
Discussion: Management options for IPDA aneurysms include radiologically guided endovascular approach or surgical repair. Given the high mortality of greater than 50% with ruptured aneurysms intervention is indicated in all detected cases.
Conclusion: Surgical excision with bypass grafting from the supra-coeliac aorta, as reported by our team, represents a satisfactory management option in patients where interventional approaches have failed or are not appropriate.
