Abstract
BACKGROUND
Endovascular aortic aneurysm repair (EVAR) has become the most popular technique to treat infrarenal abdominal aortic aneurysms. In aneurysms with unsuitable anatomy open surgical repair remains the golden standard but fenestrated EVAR (FEVAR) or branched EVAR (BEVAR) may be an alternative to treat juxtarenal or thoracoabdominal aneurysms. The aim of this study was to report our results and to evaluate its safety and feasibility.
METHODS
This is a single center cohort study analyzing all consecutive patients undergoing FEVAR or BEVAR.
RESULTS
One hundred patients underwent a procedure between June 2012 and December 2019. Forty-seven percent had a history of coronary artery disease and 31% of previous aortic repair. Sixty percent were treated for a juxtarenal and 40% for a TAAA. Primary technical success was 87%. Overall, thirty-day mortality was 6%, with 50% of the deaths resulting from a myocardial infarction. Four percent had a bowel resection for ischemia, 3% developed a stroke and 3% spinal cord ischemia. Mean follow-up was 33.6±22.4 months, freedom from all-cause mortality was 89.3±3.2% at one year and 66.4±7.6% at five years. Six intraoperative target vessel events were noted (1.7%), six early postoperative (1.7%) and three late (0.8%). A total of ten (10%) late procedure related secondary interventions were performed, among which six for endoleak.
CONCLUSIONS
This study confirms that fenestrated and branched endovascular repair is a safe and feasible treatment for juxtarenal and thoracoabdominal aortic aneurysms with acceptable complication rates. The perioperative cardiac mortality highlights the importance of preoperative risk assessment and patient selection.
