Endovascular treatment of abdominal aortic paraanastomotic pseudoaneurysms after surgical reconstruction

Purpose: To evaluate the efficacy of endovascular treatment of paraaortic postoperative abdominal aortic pseudoaneurysms. Materials and methods: From April 1996 to November 2007 five men with paraaortic postoperative abdominal aortic pseudoaneurysm underwent endovascular treatment. Average age was 64.2 years (range 54-73). The average time interval between the primary surgery and endovascular treatment was 12.4 years (4 months-23 years). Three patients were treated by aortouniiliacal stentgrafts and two patients by tube stentgrafts. Results: Technical success rate was 100%. Pseudoaneurysms were primarily excluded from circulation without perioperative complications in all patients. At follow-up (mean 38.5 months) there were no deaths and no endoleaks. In one patient thrombosis of stentgraft was found and it was successfully treated by thrombectomy. All pseudoaneurysms still continued to be excluded from circulation in the last follow-up. Conclusion: Endovascular treatment is minimally invasive, effective and safe option of surgery for paraaortic postoperative pseudoaneurysms.
