Splenic Artery Aneurysm Management with Detachable-Coil Embolization Moderate Packing

Splenic artery aneurysm (SAA) management is various but endovascular solutions are preferred for a lower incidence of mortality and morbidity. The aim is to report SAA management using moderate packing of detachable coil embolization without routine splenectomy. From January 2015 to September 2022, we retrospectively analyzed patients presenting SAA and treated by moderate packing detachable coil embolization. SAA treatment indications were transverse diameter >2 cm, any size pseudoaneurysm, any size women in childbearing age and abdominal symptoms. The measured outcomes were technical success; mortality, morbidity, abdominal symptoms onset, and splenic infarction. Median follow-up was 34.77±9 months. Seven patients (median transverse diameter of 23±20 mm) were included. Technical success was achieved in all cases. No early mortality, abdominal pain onset or recurrence, reintervention, or splenic infarction was registered. Detachable coil moderate packing embolization is safe and effective for SAA management. The moderate coil packing maintained a limited splenic vascularization in the early period and avoided splenic infarction. During the follow-up, the coil embolization allowed SAA exclusion with no SAA growth. Larger patient samples with longer follow-up are required to validate this technique.
