Literature Search Strategy
This systematic review was performed and reported in line with the
Preferred Reporting Items for Systematic Reviews and Meta-Analyses
statement [10]. We searched in PubMed and MEDLINE
(https://www.ncbi.nlm.nih.gov/pubmed/) with time point set to end of May
2021 using medical subject headings and text words supplemented by
scanning the bibliographies of recovered articles included “type A
acute aortic dissection”, “acute type A dissection”, “cerebral
malperfusion”, “brain malperfusion”, “stroke” and using the Boolean
word “AND”. Prior to data extraction, all titles, abstracts and full
texts were sequentially reviewed following inclusion criteria. Moreover,
the reference lists of the selected articles were manually screened and
reviewed to identify further relevant citations. Two co-authors (CW and
LZ) reviewed and selected relevant articles for inclusion. Differences
were resolved in consensus discussions. In order to avoid duplicates,
all included studies were independently assessed and critically
evaluated. Additional hand searching was undertaken.
