Acute type A dissection causing impending rupture of abdominal aortic aneurysm previously treated with EVAR

This report describes the rapid expansion of a previously excluded abdominal aortic aneurysm (AAA) following type A aortic dissection repair in a 74-year-old male. Following successful hemi-arch replacement, CT angiography (CTA) showed residual dissection throughout the thoracoabdominal aorta which had created a proximal endoleak at the prior endovascular stentgraft resulting in rapid growth of the residual AAA sac. Urgent thoracic endovascular aortic repair (TEVAR) did not fully obliterate false lumen flow allowing further unstable expansion of the AAA and abdominal pain.
