ABSTRACT
OBJECTIVES:
The combined disease of the aortic arch and the descending aorta (aneurysms and dissection) remains a surgical challenge. Various approaches have been used to treat this complex pathology. In the two-stage operation, at the first-stage operation, the aortic arch is replaced through a median sternotomy. Later, at the second-stage operation, the descending thoracic aorta is replaced through a lateral thoracotomy. The elephant trunk (ET) technique was introduced by H.G. Borst at our centre in March 1982, greatly simplifying the second-phase operation. We present our 30-year experience.METHODS:
From March 1982 to March 2012, 179 patients (112 males, age 56.4±12.6 years) received an ET procedure for the combined disease of the aortic arch and the descending aorta (91 aneurysms, 88 dissections (47 acute)). Fifty-six of these patients had undergone previous cardiac operations. Concomitant procedures were performed if necessary. The cerebral protection was done either by deep (till 1999) or moderate hypothermic circulatory arrest and selective antegrade cerebral perfusion (SACP, after 1999).RESULTS:
Cardiopulmonary bypass (CPB) and X-clamp times were 208.5±76.5 min and 123.7±54.8 min, respectively. The intraoperative mortality and 30-day mortality during the first-stage operation were 1.7% (3/179) and 17.3% (31/179, 15 with AADA), respectively. Perioperative stroke was 7.9% (n=14/176). Postoperative recurrent nerve palsy was present in 18.2% (32/176) and paraplegia in 5.6% (10/176). The second-stage completion operation was performed as early as possible. Fifty-seven second-stage completion procedures were performed, either surgically (n=50) or through interventional techniques (n=7). The intraoperative and 30-day mortality after the second-stage completion procedures were 5.2% (3/57) and 7.0% (4/57), respectively. The stroke, recurrent nerve palsy and paraplegia rates were 0, 0 and 7% (4/54), respectively.CONCLUSIONS:
The ET technique has greatly facilitated the two-stage approach to the surgical treatment of combined diseases of the aortic arch and descending aorta. The initial learning curve, acute dissections, re-do and concomitant procedures partially explain the higher mortality rate. Despite the development of new hybrid techniques, there is still a role for the classical ET in selected patients, particularly in the context of proven long-term results and cost effectiveness.Palavras-chave
