title: Pseudoaneurysm after cardiac catheterization: therapeutic interventions and their sequelae: experience in 86 patients.
abstract: After diagnostic cardiac catheterization in 8,715 patients, a pseudoaneurysm was diagnosed in 86 (1%) patients. Primary conservative management by repeated compression bandages (CB) or ultrasound guided compression (UGC) was attempted in all patients. Occlusion of the pseudoaneurysm was achieved significantly more often by UGC (41/47; 87%) than by CB (22/39; 56%; P = 0.016). Of 86 patients, 23 (27%) required surgical treatment. Major clinical acute complications occurred after surgery in 8/23 cases (35%) versus 4/63 (6%; P = 0.0004) following successful CB or UGC. However, intention-to-treat analysis showed no difference in the rate of acute complications in the CB or UGC group (15.4% versus 12.8%, P = 0.7272), because of a trend towards a higher complication rate following secondary surgery in the UGC (4/6 = 66.7%), as compared to the CB group (4/17 = 23.5%, P = 0.1589). During follow up, 22/64 (34%) patients reported persistent inguinal complaints, 9/15 (60%) after surgery and 13/49 (27%) after successful CB or UGC (P = 0.0169). However, according to the intention-to-treat analysis, there was no significant difference between the initial groups (CB: 26.1% versus UGC: 39.0%, P = 0.2958). Despite a higher effectiveness of UGC to achieve occlusion of a pseudoaneurysm compared to CB (87% vs. 56%), UGC is not superior to CB because of a higher rate of acute complications as well as long-term complaints in those patients requiring secondary surgery in the UCG group as compared to the CB group.
