While patient eligibility for carotid artery stenting (CAS) is well established, the intraoperative technique remains widely varied. The decision to perform poststent ballooning (PSB) is operator-dependent and often influenced by the interpretation of poststent angiography. While visually creating a greater luminal diameter, it is unclear whether PSB has immediate risks or long-term benefits. The purpose of this report is to determine whether PSB has any effects on periprocedural hemodynamic stability.

A retrospective analysis of all patients that underwent CAS between 2005 and 2012 at a tertiary care center was performed. The primary end point was hemodynamic instability, defined as bradycardia (a heart rate of <60 beats/min) or hypotension (systolic blood pressure of <90 mm Hg) during the intraoperative or postoperative period. Binary logistic regression model was performed to determine the …
