Transcatheter Arterial Embolization of Splenic Artery Aneurysms and Pseudoaneurysms: Short- and Long-Term Results

Clinical efficacy of transcatheter embolization of visceral artery pseudoaneurysms using N-butyl cyanoacrylate (NBCA)

“…However, when the microcatheter could not readily approach the pseudoaneurysm entrance and a stable catheter position could not be achieved, we used the isolation technique, with a lower NBCA to Lipiodol ® Ultra-Fluide mixing ratio (1:3). In fact, the selection of a pseudoaneurysm neck is rarely achieved in cases of visceral pseudoaneurysm, and there is a risk of pseudoaneurysm rupture when deploying the embolic material due to the increase in intra-aneurysmal pressure [10,17]. We treated most cases with the isolation technique and fixed the ratio at 1:3 (i.e., 25% NBCA).…”

“…Therefore, treatment of pseudoaneurysms is highly recommended because bleeding from pseudoaneurysms is associated with high mortality rates [10,11]. Pseudoaneurysms may be distinguished from true aneurysms both clinically and by imaging.…”

Giant Splenic Artery Pseudoaneurysm

“…1,2,[7][8][9][10] A review of the English language literature identified 160 cases of splenic artery pseudoaneurysm reported in the last 43 years. 1-10 These ranged in size from 0.3 to 17 cm, and of these, 18 (11%) were 5 cm or larger (giant pseudoaneurysms; Table 1).…”

Spontaneous Splenic Rupture Following Bouts of Coughing: A Rare Case Report and Literature Review

“…Selective Splenic Rupture Following Coughing J Curr Surg. 2016;6(3-4):81-85 embolization can potentially retain splenic function due to the development of collaterals [31][32][33]. Preservation of viable splenic tissue is desirable if possible [34].…”
