Development of endotension after multiple rounds of thrombolysis after endovascular aneurysm repair

Endoleaks, defined as blood flow outside the graft but inside the aneurysm sac, are a common complication after endovascular aneurysm repair. Sometimes however, for reasons not fully understood, expansion of the aneurysm sac can occur with no identifiable endoleak, a phenomenon termed endotension, or a type V endoleak. We describe a case of endotension in a 71-year-old man that developed after recurrent stent graft thrombosis requiring thrombolysis 3 years after the initial endovascular implantation. To our knowledge, this is the first description in the literature of endotension after multiple rounds of thrombolytic treatment.
