Endotension after endovascular treatment of abdominal aortic aneurysm: percutaneous treatment.

Endotension is one of the possible specific late complications of endovascular treatment of abdominal aortic aneurysm (AAA). We describe the treatment of endotension in a small group of 3 patients (all men, aged 58, 70, and 70-years-old) by translumbar puncture of the aneurysm sac and aspiration of its content. It was transudate and its culture was negative. Sac size reduced after aspiration in all patients and no subsequent enlargement was seen. Percutaneous translumbar puncture of the aneurysm sac with aspiration of sac content could be an easy and effective method of treatment in endotension. But a larger group of patients and long-term follow-up are needed.
