Emergent treatment of a primary aortoenteric fistula with N-butyl 2-cyanoacrylate and endovascular stent.

A novel endovascular treatment involving cyanoacrylate injection followed by endovascular stent placement is described in the setting of life-threatening acute exsanguination through a primary aortoenteric fistula. In a patient in unstable condition, N-butyl 2-cyanoacrylate was injected into the fistula tract. Rapid polymerization first provided hemostasis and allowed the patient to be resuscitated and stabilized for several hours, and then an AneuRx endovascular stent-graft was deployed to reinforce the aortic wall and permanently occlude the fistula. This approach can benefit patients whose condition would otherwise be too unstable for open surgery.
