Percutaneous treatment of pseudoaneurysms using fibrin adhesive.

摘要

This study was performed to assess the safety and efficacy of treatment of iatrogenic pseudoaneurysms with fibrin adhesive. 28 patients with iatrogenic pseudoaneurysms were treated. The first 20 patients had either at least one previously unsuccessful treatment of ultrasound guided compression repair (UGCR), a contraindication to UGCR or could not tolerate the procedure. Diagnosis was confirmed on ultrasound and angiography and a balloon inflated across the neck of the pseudoaneurysm. Fibrin adhesive was injected under ultrasound control directly into the pseudoaneurysm sac. The balloon was deflated after 15 min and check ultrasound and angiography performed, with a further ultrasound at 24 h. The subsequent eight patients underwent embolisation as the first line treatment without use of a protective balloon. 16 of the first 20 patients (80%) and all of the subsequent 8 patients had successful embolisation of the pseudoaneurysm after a single treatment. Two pseudoaneurysms failed to thrombose despite two treatments in one case and three treatments in the other, and both required surgery. The only significant complication was the development of local cellulitis in one patient. In conclusion, embolisation of iatrogenic aneurysms with fibrin adhesive is a safe and effective treatment. It should be considered as an alternative to surgery and UGCR.
