PURPOSE: To report our experience with endovascular stent-graft repair of descending thoracic aorta diseases in high risk patients.
MATERIALS AND METHODS: Between 2000 and 2007, 49 high surgical risk patients (mean age: 64.6 years) underwent stent-graft placement, including 24 cases presenting acutely. Mean follow-up was 25.4 months. Etiologies included 15 aneurysms, 11 dissections, 10 penetrating ulcers, 9 false aneurysms, 2 ruptures of the aortic isthmus, 2 intramural hematomas.
RESULTS: Access failure occurred in one patient. The overall mortality was 27.1% (n=13), nine related to the presenting pathology or treatment. Thirty-day mortality was 10.4% (n=5). Complications included vascular injury at the iliac or femoral artery access (10.2%), 1 case of flaccid paraplegia, 2 cases of transient paraparesis, 2 strokes, 2 stent migrations and 1 stent rupture. The rate of early endoleak was 39.6% while the rate of delayed endoleak was 14.6%. Seven patients (14.6%) required repeat endovascular interventions. Explantation was required in 2 cases. The latest available follow-up showed no lesion enlargement in 70.7% (n=29/41) of our patients.
CONCLUSION: Descending thoracic aortic pathology can be treated using endografts in high risk patients, although significant morbidity and mortality remain. Because of the high rate of endoleaks, close follow-up is required.
