ArtVentive endoluminal occlusion system for proximal splenic artery embolization

Area of Science:

• Interventional Radiology
• Vascular Surgery

Background:

• Splenic artery embolization is crucial for managing splenic hemorrhage and other conditions.
• The ArtVentive endoluminal occlusion system (EOS) offers a novel approach to splenic artery occlusion.

Purpose of the Study:

• To evaluate the technical success and efficacy of the ArtVentive endoluminal occlusion system (EOS) for splenic embolization.
• To assess the safety and outcomes of EOS device deployment in patients undergoing splenic artery embolization.

Main Methods:

• Retrospective review of patients who underwent splenic embolization using the EOS device.
• Analysis of procedural data, including demographics, technical success rates, and one-month follow-up outcomes.
• Review of hospital computer database for splenic artery embolization procedures.

Main Results:

• The EOS device was deployed in 6 patients (5 male, 1 female; age 24-88 years).
• Technical success rate was 100% in all 6 splenic arteries treated with EOS plugs (five 8 mm, one 5 mm).
• One patient required a second angiogram and splenectomy for persistent hemorrhage; another had a splenectomy for suspected bacteremia.

Conclusions:

• The ArtVentive endoluminal occlusion system (EOS) shows promising 100% technical success for proximal splenic artery embolization.
• Early data supports the efficacy of the EOS plug for splenic artery occlusion, though further investigation into complications is warranted.
