Multiple recurrent cystic echinococcosis with abdominal aortic involvement: A case report

Figure 1 Preoperative computed tomography and angiography. A and B: Computed tomography scan showed a lesion in the abdominal cavity and a retroperitoneal lesion, which was firmly attached to the abdominal aortic wall; C: At the arterial phase, an aortic branch was found to be buried in the lesion with a dead end; D: Angiography showed further evidence of the dead-end arterial branch of the abdominal aorta, and calcified splenic lesion after the initial splenic cystic echinococcosis surgery.

Figure 2 Digital subtraction angiography and vascular stenting. A: During digital subtraction angiography, abdominal aortic angiography revealed no apparent arterial bleeding, which was a major sign of successful suturing during open surgery; B: Image after arterial covered stent placement into the diseased aortic section, and major branches were still hemodynamically functional.
