Complex Iatrogenic Dissection Complicating Thoracic Endovascular Aneurysm Repair.

BACKGROUND

To report one the most feared complication of thoracic endovascular aneurysm repair (TEVAR); a retrograde aortic dissection who can involve the aortic arch or ascending aorta, which require commonly coextensive open surgical repair.

CASE REPORTS

We report 2 cases of combined retrograde and antegrade dissection after endovascular treatment of an aneurysm of the descending aorta. In both cases, a dissection was identified at short-term follow-up; which required open surgical repair in one case and an additional endovascular treatment for the second case.

CONCLUSIONS

The incidence of extensive iatrogenic dissection after TEVAR is relatively low, open repair should be considered as a primary option in some cases with limited aortic dilatation to avoid such life-threatening complications.
