Ziapour B, et al. - The short-term impact of different ballooning combinations on hemodynamic instability neurologic events, and mortality associated with carotid artery stenting was examined. Searching the Cochrane Library trials register, PubMed, EMBASE, Google Scholar, and the US National Library of Medicine clinical trial databases were searched up to May 2019, researchers included seven cohort studies for qualitative review; of these, six were selected for meta-analysis. Outcomes suggest that perioperative hemodynamic instability reduced with avoiding postdilation and this benefit remains at least up to 30 days. The neurologic events during and 30 days after the carotid artery stenting possibly reduce with fewer dilations during the procedure regardless of the type. Further, the data infer that the residual stenoses above the current practiced standard may render a safer threshold to aid postdilation.
