ReviewMight type A acute dissection repair with the addition of a frozen elephant trunk improve long-term survival compared to standard repair?
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was: in patients with an acute type A dissection (TAAD) is a frozen elephant trunk in addition to standard aortic dissection repair advantageous in terms of improved long-term mortality and closure of the distal false lumen? Altogether more than 138 papers were found using the reported search, of which six represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. ⋯ However, this procedure can be performed safely without increase the operative mortality and morbidity but with an overall higher cardiopulmonary bypass and circulatory arrest time. Spinal cord ischemia and malperfusion syndrome represents the main complications associated with this procedure. Despite few studies, this procedure seems to allow early thrombosis of the false lumen and a reduction of late thoraco-abdominal aneurysm formation and reoperations rate.
