Hybrid Repair of Aortic Arch Aneurysms with Endografting of the Ascending Aorta

BACKGROUND

Different "hybrid" techniques that combine open debranching of the supra-aortic vessels with endografting of the aortic arch have emerged as alternatives to the open arch repair in high-risk patients. This study aims to review the early and mid-term results of single-stage hybrid arch repair with ascending aorta stent graft deployment for aortic arch aneurysms and dissections.

METHODS

Between June 2006 and May 2015, five consecutive patients, with an age range of 54-78 years, with complex aortic arch diseases, were treated with a hybrid approach in which the endograft had a proximal landing zone in the ascending aorta. Indications included: acute and chronic type A aortic dissections and three arch aneurysms associated with distal aortic pathology. Length of postoperative clinical and imaging follow-up ranged from 10 to 121 months and was completed in all patients.

RESULTS

Technical success of the endografting was achieved in all cases. There was one in-hospital mortality secondary to pulmonary embolism, one case of retrograde type A aortic dissection (RTAD) detected before discharge and one case of late type Ib endoleak that required an endografting procedure. No postoperative stroke or transient or permanent spinal cord ischemia occurred.

CONCLUSION

Hybrid arch repair with endograft landing in zone 0 may decrease mortality and morbidity in high-risk patients.
