Summary:
Purpose: To provide an overview of the medical literature on splenic artery aneurysms in order to evaluate the applications of endovascular techniques, their methods, their results and post-operative complications in comparison with older treatments.
Methods: A multiple electronic health database search was performed, including PubMed, Medline and EMBASE on all articles related to splenic artery aneurysms. In total, the research yielded 7 series of patients through the time period of 1995-2017, included 1509 patients suffering from splenic artery aneurysm.
Results: Of all 1509 splenic artery aneurysms, 55% were treated using endovascular techniques and 45% with open surgery (835 and 674 respectively). In more detail, of all patients treated using endovascular techniques, 13% (106 patients) were symptomatic and 7% (59 aneurysms) were ruptured. In 91% of all cases the treatment was transcatheter embolization while in the rest of 9% the treatment was stent graft placement (438 and 43 patients respectively). Technical success was achieved in 97%, the mean length of hospital stay was 3,5 days and thirty-day mortality was 1,2% (10 patients). The mean length of follow-up was 29 months, 21% experienced post-operative operations (171 patients) and 6,5% (31 patients) required reintervention.
Conclusion: Endovascular repair represents the first line treatment for splenic artery aneurysms and appeared to be effective with good post-operative outcomes. Endovascular techniques are constantly evolving and increasingly used for splenic artery aneurysms achieving better results.
