The stented elephant trunk procedure combined total arch replacement for Debakey I aortic dissection: operative result and follow-up.
The stented elephant trunk technique in aortic arch replacement combined with transaortic stented graft implantation into the descending aorta has been introduced as a means of eliminating the residual false lumen in the descending thoracic aorta and improving long-term outcomes of surgical intervention for Debakey I aortic dissection. This report summarizes the operative and follow-up data with this new procedure. Between August 2004 and May 2009, 28 stented elephant trunk operations were performed for Debakey I aortic dissection at Nanjing First Hospital. A 10 cm long woven Dacron graft was implanted through the aortic arch during hypothermic circulatory arrest. Patent false lumina were evaluated using computed tomography three months after the operation. Mean cardiopulmonary bypass time was 213.2±47.2 min, and selected cerebral perfusion time was 38.8±9.7 min. Hospital mortality was 14.3% (4/28). Thrombus obliteration of the residual false lumen in the descending aorta was observed in 91.7% of the aortic dissections three months postoperatively. The survival rate was 87.5% at five years and the freedom from reoperation rate was 91.7%. Total aortic arch replacement combined with transaortic stented graft implantation into the descending aorta is an effective treatment for Debakey type I aortic dissection.
