Abstract

Purpose To evaluate the results of interventional endovascular therapy of incidental and symptomatic visceral artery aneurysms in the elective and emergency situation. Materials and Methods 43 aneurysms in 38 patients (19 female, 19 male, mean age: 57 ± 16 years [18 - 82]) were treated between 2011 and 2015. The characteristics of the aneurysms (true vs. false aneurysm, size, etiology, location, symptoms) were considered. Furthermore, we evaluated the intervention with respect to technical success, embolic/occlusive agents used, therapy-associated complications and post-interventional follow-up.  Results 23 true aneurysms (maximum diameter: 22 ± 18 mm [11 - 67 mm]) and 20 false aneurysms (maximum diameter: 9 ± 33 mm [3 - 150 mm]) were evaluated. The splenic (n = 14) and renal arteries (n = 18) were most frequently affected. The etiology was most commonly degenerative-atherosclerotic (47 %) or iatrogenic post-operative (19 %). 18/48 interventions were performed due to active bleeding. False aneurysms were associated significantly more often with active bleeding (63 vs. 25 %, p = 0.012). 41/48 treatments were technically successful. Re-intervention was necessary 6 times. In 2 cases the endovascular approach did not succeed. There...Continue Reading
