Purpose:
We aimed to assess the safety and efficacy of the double microcatheter technique in the treatment of saccular splenic artery aneurysms.
Methods:
From November 2013 to October 2020, 56 patients with saccular splenic artery aneurysms underwent endovascular treatment with the double microcatheter technique at our institution. Technical success was defined as embolization of the aneurysmal cavity with no obstruction of the parent artery. Clinical success was defined as no deaths due to splenic artery aneurysms, and no reintervention, recrudescence or organ dysfunction at 1, 6, and 12 months.
Results:
The technical success rate was 100%. No major complications related to angiography or embolization were observed. Minor complications included fever, pain, and nausea, and 13 patients developed minor complications. At 1 month, the rate of clinical success was 96.4%. At 6 and 12 months, the clinical success rate was 92.9%. There were no aneurysmal recurrences or necessities of reintervention.
Conclusions:
Coil embolization with the double microcatheter technique is a safe and effective modality for treating saccular splenic artery aneurysms and offers a reasonable choice for patients who want to retain their original hemodynamics.
