While the European Society for Vascular Surgery (ESVS) recommends endovascular repair as the first-line treatment, open surgery remains a valuable option when endovascular repair is not feasible due to clinical or technical constraints.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>A systematic literature review was conducted covering the period from 2010 to 2024. Twenty-five surgically treated SMAA cases were identified.

Indications for open repair included mycotic aneurysm (48%), collagenous disease or fibrodysplasia (20%), emergency repair for hemoperitoneum (4%), and unfavorable anatomy for endovascular treatment (28%). Surgical techniques included simple aneurysmectomy (56%) and aneurysm resection with graft reconstruction (44%). No intra- or postoperative bleeding or major complications were reported. In-hospital mortality was 16%, primarily due to acute bowel ischemia (12%). Among survivors, vascular reconstructions demonstrated 100% patency at a mean follow-up of 14\u00a0months (range 1\u201348\u00a0months), with no need for reintervention and no deaths during follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Open surgical repair remains a viable treatment option in cases of infected SMAA, collagenous disease, or complex anatomy unsuitable for endovascular repair.
