Midterm results of endovascular repair of thoracic aortic false aneurysm formation after coarctation repair.

BACKGROUND

The aim of this study was to evaluate the short-term and midterm results of endovascular repair of false aneurysm formation after coarctation repair.

METHODS

Between November 1998 and August 2009, seven patients underwent endovascular repair for false aneurysm formation after coarctation repair (two women, five men; mean age: 45.4 ± 12.1 years; range: 30-60 years). Follow-up computed tomography scans were performed at 1 week, 3 months, 6 months, and annually thereafter.

RESULTS

All endografts were successfully deployed (Excluder-TAG in three patients, Talent in one patient, Valiant in three patients). Among them, six patients underwent hybrid technique with supra-aortic debranching and simultaneous or staged endovascular stent grafting as follows: transposition of the left common carotid artery (LCCA) into the brachiocephalic trunk which was later followed by transposition of the left subclavian artery into the LCCA in one case and transposition of the left subclavian artery into the LCCA in remaining five cases. No major complications occurred. A mean follow-up of 44.8 ± 41.3 months (range: 1-131 months) demonstrated no endoleak, rupture, conversion, or migration.

CONCLUSIONS

Short-and mid-term results of endovascular treatment of false aneurysm formation after coarctation repair favor the proposition of endovascular repair as a first-line treatment option. Long-term survival studies are mandatory to determine the efficacy and durability of this technique.
