Endotension--a late complication successfully treated by open repair.

Endotension is a late complication following endovascular treatment of abdominal aortic aneurysm (AAA). A 83-year-old male had a successful endovascular repair of a 5.6 cm diameter AAA. During the follow-up period it was marked that the aneurysm continued to increase in size, became 6.6 cm maximal diameter and pulsatile with no evidence of endoleak. On laparotomy no endoleak was identified and the graft was left in situ. Postoperatively and on follow-up the patient remains asymptomatic while the aneurysm continued to appear shrunk.
