Acute ischemia in chronic type B dissections carries high rates of morbidity and mortality. A 29-year-old woman with a chronic type B dissection presented with acute abdominal pain. Imaging revealed a worsening dissection with pseudocoarctation causing near complete occlusion of the true lumen by the false lumen. We placed purposefully undersized stent grafts to treat acute mesenteric ischemia by improving true lumen flow. The patient was discharged on postoperative day 4 without adverse events. We suggest that endovascular rescue by placing undersized stent grafts can provide improved flow to the mesenteric vessels with continued false lumen flow to vital organs.
