    Abstract:
    OBJECTIVES: To evaluate the endovascular treatment of pseudo-aneurysms (PAs) with super-selective coil embolisation using the 3D packing technique. DESIGN: Retrospective study of consecutive patients in one academic centre. MATERIALS: From 2002 to 2009, 16 patients (mean age 51.6 years, range 24-82) underwent PA sac packing with coils. Four patients were asymptomatic, nine had PA rupture, and three had other symptoms. Lesion location was as follows: splenic artery (8), carotid artery (2), hepatic artery (2), superior mesenteric artery (1), cystic artery (1), uterine artery (1), and hypogastric artery (1). METHODS: The sac was packed with 0.018-inch controlled-detachable microcoils, preserving the parent artery. Magnetic resonance angiography was done within 6 months, at 12 months then yearly. RESULTS: Technical success rate was 100%. Complete definitive PA exclusion was achieved with a single procedure in 15 (93.8%) patients. One patient with a secondary bleeding arterio-digestive fistula underwent successful surgery. No major complications or late recanalisations occurred during follow-up (mean, 24.7 months; range 6-49). CONCLUSIONS: Coil PA embolisation by 3D sac packing is safe and effective and may induce less morbidity than complete parent vessel occlusion, stent placement, or open surgery. This procedure should be used whenever possible, as it preserves parent artery patency.
