Endografting under Assistance of Transapical Body Floss Through-and-Through Wiring Technique and Rapid Ventricular Pacing for an Ascending Aortic Tuberculous Pseudoaneurysm.

BACKGROUND: To demonstrate an ascending aortic tuberculosis pseudoaneurysm successfully treated with endografts under assistance of trans-apical body floss wiring technique and rapid ventricular pacing support.

METHOD AND RESULT: A 77-year-old woman with a non-healing anteromedial chest wound presented with sudden hypotension and hemoptysis. The computed tomography (CT) scan revealed a 9-cm-diameter pseudoaneurysm of ascending aorta, with sternal erosion close to the wound. Conventional open repair was not preferred due to possible contamination of interposition graft and difficult sternum closure. The feasibility of endografting was confirmed based on appropriate landing zones. After endografts modification at back table, we made a left mini-thoracotomy and establish a through-and-through body floss wire from left ventricular apex to femoral artery. Retrograde delivery over this wire from femoral artery to ascending aorta and deployment of endografts under rapid ventricular pacing support were performed smoothly. Final angiography showed no endoleaks with patent coronary and arch vessels. Further wound debridement was done at the same time and wound culture yielded tuberculosis. After completing anti-tuberculosis therapy, no recurrent infection occurred. Postoperative 6-month CT scan disclosed optimal result.

CONCLUSION: With adequate landing zones and delicate surgical strategy, endografting with anti-tuberculosis therapy may be an alternative treatment for ascending aortic tuberculosis pseudoaneurysm.
