RESUMO

PURPOSE: The aim of the study is to analyze our single-center experience in endovascular treatment of splenic artery aneurysms (SAAs) with transcatheter coil embolization, comparing long-term outcomes of packing and sandwich techniques. MATERIALS AND METHODS: Between January 2010 and December 2021, 28 patients with certain diagnosis of non-ruptured asymptomatic SAA were treated with 2 different embolization techniques (packing, n=10, and sandwich, n=18). Early outcomes assessed were technical success, overall mortality, mean hospital stay, post-embolization syndrome rate, and freedom from splenectomy rate. Estimated 5-year outcomes in terms of freedom from sac reperfusion, and freedom from reintervention were evaluated and compared between the 2 different embolization techniques. RESULTS: The mean SAA diameter was 2.8±0.8 cm. Overall technical success rate was 100%. Intraoperative and 30-day mortality rates were 0 in both groups. One patient in the sandwich group required a postoperative splenectomy. The mean follow-up period was 58.3±44.5 months. Estimated overall 5-year survival was 86.7%. Five-year freedom from sac reperfusion was 100% in the sandwich group, and 85.7% in the packing group, with no difference between the 2 groups (p=0.131), whereas freedom from reintervention was 100% in the sandwich group, and 75% in the packing group with a statistically significant difference (p=0.049; log-rank=3.750). CONCLUSIONS: Embolization of SAAs seemed to be safe and effective with 100% of technical success rate and good perioperative results. Both sandwich and packing techniques yielded promising results also in the long-term period. CLINICAL IMPACT: Transcatheter coil embolization of splenic artery aneurysms seems to be a safe and effective procedure with a 100% technical success and satisfactory perioperative outcomes. Sandwich and packing techniques offer good results in the long-term period. Freedom from reintervention seems to be optimal and comparable between the 2 techniques.
