Ileal hemorrhagic infarction after carotid artery stenting: A case report and review of the literature

Figure 1 Preoperative digital subtraction angiography findings. A: The type III aortic arch; B: The bifurcation of the left common carotid artery was severely stenosed; C: The stenosis at the bifurcation of the left common carotid artery was significantly improved.

Figure 2 Abdominal enhanced computed tomography changes after carotid artery stenting. A: Intestinal obstruction and edema of the intestinal wall; B: The superior mesenteric artery showed severe stenosis and poor distal angiography.

Figure 3 Pathology of the ileectomy site after partial ileectomy. A and B: Intestinal mucosa necrosis, exfoliation, full-thickness vasodilation and hyperemia, fibrinous exudation, and necrosis of serous membrane are visible, thus indicating ileal hemorrhagic infarction.

Figure 4 Abdominal enhanced computed tomography changes after the abdominal drainage tube under the guidance of ultrasound. A: The drainage tube was unobstructed without intestinal obstruction; B: Abdominal enhanced computed tomography after removal of the abdominal drainage tube showed no intestinal obstruction or flatulence; C: Follow-up computed tomography angiography at the 6-mo after carotid artery stenting showed that the carotid artery stent was patent.
