Is carotid artery stenting in octogenarians really dangerous?
In our experience, CAS has proven to be safe and effective in elderly patients. Different age-related anatomical features can represent an adjunctive technical challenge, but these difficulties can be successfully managed without increased perioperative risk if CAS is performed in high-volume centers by highly skilled operators.
Results of this analysis demonstrate these two environmental vibrios, previously characterized as variant V. cholerae strains, are new species which have evolved from ancestral lineages of the V. cholerae and V. mimicus clade. The presence of conserved integration loci for genomic islands as well as evidence of horizontal gene transfer between these two new species, V. cholerae, and V. mimicus suggests genomic islands and virulence factors are transferred between these species.
