6.0 Conclusions
Non-A non-B aortic dissections represent a small proportion of the total
number of dissections that occur annually, and this is reflected in the
quantity of studies published in the literature. By definition non-A
non-B dissections fall outside of the standardised classifications for
aortic dissections despite the literature showing that a significant
majority of these patients have a complicated disease course which has
been shown to occur more frequently than other types of aortic
dissection. Studies from around the world have demonstrated that
surgical intervention when compared to medical management produce far
more satisfactory 30-day mortality rates, with both open surgical and
endovascular techniques providing good short-term results. Despite these
published findings, further large-scale prospective studies are required
in order to improve our understanding of best treatment and to provide
more substantial evidence for the application of different surgical
techniques for this subset of aortic dissections.
