This protocol addresses a vascular emergency: patients presenting with a splenic artery pseudoaneurysm, or with a ruptured or impending ruptured true splenic artery aneurysm — a high-risk subgroup requiring urgent intervention.
This presentation encompasses splenic artery pseudoaneurysm and either ruptured or impending ruptured true aneurysm. The significant risk of hemorrhage and associated mortality in this group makes urgent, structured management essential.
An emergency endovascular approach is the central intervention for this presentation, performed as soon as possible once the diagnosis is established. The complete structured regimen — including the full intervention pathway and procedural specifics — is available via the link below.
The treatment target is complete exclusion of the splenic artery aneurysm, confirmed by angiography performed immediately following the procedure.
Type V includes pseudoaneurysm and either ruptured or impending ruptured true aneurysm.
Owing to the high risk of hemorrhage and significant mortality risk in type V SAAs, we recommend performing endovascular or surgical treatment as soon as possible once diagnosed.
If the patient's condition is stable, an initial attempt at endovascular therapy like splenic artery embolization, as demonstrated by two cases in this study, is feasible.
Technical success was defined as complete exclusion of the aneurysm via immediate postoperative angiography and complete occlusion or resection of the aneurysm under endoscopy or direct visualization.
