Aim: Open surgical repair (OSR) and endovascular techniques (ET) are both described in the literature for treating visceral artery aneurysms (VAAs). Aim of this study is to report a two-center experience of patients treated for a VAA using either OSR or ET, analyzing perioperative outcomes.
Methods: Clinical data of 32 VAAs in 32 patients treated between January 2001 and May 2011 were retrospectively reviewed and outcomes analyzed.
Results: Eighteen patients were men (56.3%). Median age was 64 years (range 26-79). Sixteen aneurysms were symptomatic: half of them were ruptured causing hemoperitoneum or gastrointestinal bleeding. ET were employed in 19 cases (59%) using covered stents (7 patients), coil embolization (5), plug placement (1), thrombin injection (2) and multiple associated techniques (4). OSR consisted in aneurysmectomy with end to end anastomoses (5 patients) or interposition graft (1), aneurysm ligation (4), splenectomy (2). One patient died during open surgery for hemoperitoneum due to VAA rupture (3%). OSR and ET had similar perioperative complication rates (5.2% vs. 15.3%, P=0.76). OSR had a longer in-hospital stay than ET (8 vs. 4 days, P=0.04). The presence of pancreatitis and alcohol abuse were more frequent in patients who presented with VAAs rupture. Clinical presentation with hemoperitoneum or aneurysm rupture were associated with higher mortality, regardless of the type of treatment.
Conclusion: Both OSR and ET offered a safe way to treat VAAs in our experience.
