Treatment of Unruptured Splenic Artery Aneurysm: Non-Narrow-Necked Saccular Type in the Secondary Branch or Splenic Hilum
Clinical Scenario
This protocol applies to splenic artery aneurysms that are non-narrow-necked and saccular in morphology, situated in the secondary branch of the splenic artery or at the splenic hilum. This anatomical and morphological pattern defines a distinct treatment category within splenic artery aneurysm management.
Treatment Approach
An endovascular isolation strategy is the recommended first-line approach for this aneurysm type, performed with intraprocedural anticoagulation. The complete procedural details, technical steps, and full intervention algorithm are available in the structured protocol below.
Treatment Goal
Complete exclusion of the splenic artery aneurysm, confirmed on immediate postoperative angiography.

- Type III consists of non-narrow-necked saccular aneurysms situated in the secondary branch or splenic hilum.
- For type III of SAA, isolation embolization is recommended first.
- 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.
