The Teaching Point

Endovascular repair of splenic pseudoaneurysm is a useful tool but could be accompanied by late and unexpected complication as migration of the covered stent into the stomach; many factors could be involved in the pathogenesis as the inflammatory state of the patient (e.g.: previous surgery, chemotherapy, inflammatory diseases). Mild abdominal pain could be caused by such complication and physicians should be aware about this and should investigate for medical history of endovascular treatment.

Late Migration of a Covered Stent into the Stomach after Repair of a Splenic Artery Pseudoaneurysm

Abstract
We would like to report our experience of a rather rare complication that occurred in a 76-year old patient tree years after endovascular repair of a splenic artery pseudoaneurysm with a covered stent. Three years after stent insertion, the patient complained of mild abdominal pain and melena; it was revealed endoscopically that the covered stent has eroded the stomach wall and migrated into the stomach. The splenic artery is the most common location among the spectrum of potential presentation sites of visceral arteries aneurysms and pseudoaneurysms. Endovascular treatment with the use of coils or stents is the first option due to lower morbidity and mortality than open surgery. Endovascular repair may also lead to complications and patients need to be followed up in order to confirm aneurysm sealing, and exclude late complication. Minor stent graft migration may occur in the long term, however extra vascular migration is extremely rare.
