Endovascular therapy for visceral artery aneurysms

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Medical Devices

Background:

• Visceral artery aneurysms (VAAs) pose significant risks, including rupture and bleeding.
• Endovascular therapy offers a minimally invasive alternative to open surgical repair.

Purpose of the Study:

• To evaluate the outcomes and complications of endovascular treatment for visceral artery aneurysms.
• To assess the efficacy of endovascular techniques in managing diverse VAA etiologies.

Main Methods:

• Retrospective analysis of 40 endovascular procedures for VAAs in 33 patients (2009-2014).
• Procedures included coil embolization (with or without adjuncts) and stent-graft exclusion.
• Indications: aneurysm size, bleeding, mycotic aneurysms.

Main Results:

• The splenic artery was the most common site for true and pseudoaneurysms.
• Coil embolization achieved an 88% patency rate with stent grafts.
• Complications included spleen infarctions, managed conservatively or surgically.

Conclusions:

• Endovascular therapy is an effective treatment for visceral artery aneurysms regardless of their cause.
• Minimally invasive techniques provide a safe and successful management strategy for VAAs.
