ABSTRACT

Objectives: To describe thoracic endovascular aortic repair (TEVAR) outcomes at the Royal Brisbane and Women’s Hospital between 2001-2010. Design: Prospective cohort study. Results: We successfully treated 95 of 97 patients for a 98% procedural success rate. Of the treated patients, 68 (72%) were males and mean age was 61 ± 17 years. Average follow up was 3.6 ± 2.0 years. Pathologies treated were: dissection (n = 35), aneurysmal disease (n = 32), traumatic disease (n = 19), coarctation (n = 5) and miscellaneous (n = 4). There was one peri-procedural myocardial infarction. Renal complications occurred in 7 patients (3 with doubling creatinine and 4 requiring temporary renal replacement therapy). Stroke occurred in 2 patients and paresis in 2 patients (permanent in one). Six patients died during index hospitalization and 17 deaths occurred during follow-up, 2 of which were confirmed secondary to aortic pathology. Age (HR 1.08 per year, p < 0.01) and ASA class (HR 2.2 per class, p = 0.02) were independently associated with mortality. There were 25 re-interventions in 22 patients. Eighteen of these re-interventions in 16 patients were related to the management of complications of TEVAR of which 13 were for endoleaks; eight type I, four type II, one type III. Conclusion: TEVAR can be used to treat thoracic aortic pathology but questions remain regarding long-term durability.
