Summary
Emergent embolotherapy effectively treated life-threatening bleeding from ruptured splanchnic artery pseudoaneurysms in most patients. Permanent embolic materials are recommended for initial embolization procedures to ensure complete hemostasis.
Area of Science:
- Interventional Radiology
- Vascular Surgery
Background:
- Ruptured splanchnic artery pseudoaneurysms can cause life-threatening hemorrhage.
- Embolotherapy is a potential treatment option for these conditions.
Purpose of the Study:
- To evaluate the effectiveness of emergent embolotherapy for ruptured splanchnic artery pseudoaneurysms.
- To compare the outcomes of permanent versus temporary embolic materials.
Main Methods:
- Retrospective analysis of 17 patients with ruptured splanchnic artery pseudoaneurysms treated with emergent embolotherapy.
- Use of permanent embolic materials (stainless steel coils, microcoils, Ivalon) and temporary materials (Gelfoam particles).
- Superselective catheterization techniques were employed.
Main Results:
- Complete hemostasis was achieved in 16 out of 17 patients (94%).
- Initial embolization with permanent materials resulted in hemostasis in 11 out of 12 patients (92%).
- Initial embolization with Gelfoam particles failed in 6 out of 9 patients (67%), requiring additional treatment.
Conclusions:
- Emergent embolotherapy is a highly effective treatment for ruptured splanchnic artery pseudoaneurysms.
- Permanent embolic materials are superior to Gelfoam particles for initial embolization.
- Superselective embolization with permanent materials should be the primary treatment strategy.
