“…Although endovascular stent grafting has not been prospectively studied for this clinical scenario, US Food and Drug Administration-approved devices are being used "off label," with considerable success reported based on retrospective studies. In a collected series of 284 patients reported in the literature, Lettinga-van de Poll and colleagues reported the procedure-related mortality was 1.5%, 6.7% had endoleaks, and 14.4% had procedure-related complications (358,(365)(366)(367)(368)(369)(370).
