ABSTRACT
Purpose To investigate whether the sedation mode (ie, conscious sedation [CS] vs general anesthesia [GA]) affects the angiographic workflow applied for treatment of endovascular stroke in a post hoc analysis of a recent randomized controlled trial, Sedation versus Intubation for Endovascular Stroke Treatment (SIESTA). Materials and Methods SIESTA was an institutional review board-approved, single-center, prospective, randomized, parallel-group, open-label treatment trial with a blinded end-point evaluation to compare GA with CS for treatment of endovascular stroke in 73 and 77 patients, respectively. By using descriptive data from SIESTA, the influence of the mode of sedation on angiographic workflow during treatment for endovascular stroke (eg, procedure times) and other radiologic outcome parameters (eg, radiation exposure) were analyzed. The time between angiographic key steps for patients who underwent GA and CS was evaluated with t tests. P values were corrected for false discovery rate. Results The median time from groin puncture to first intracranial flow restoration with CS was 47 minutes (interquartile range [IQR], 29-70 minutes), and for GA, it was 41 minutes (IQR, 28-60 minutes) (P = .546). The median time to the end of angiography with CS was 104 minutes (IQR, 75-150 minutes), and with GA, it was 73 minutes (IQR, 53-125 minutes) (P = .052). Fluoroscopy time with CS was 49 minutes (IQR, 25-85 minutes), and with GA, it was 35 minutes (IQR, 20-74 minutes) (P = .098). The times were comparable in both groups for these measures. The time from groin puncture to the final angiographic result with GA, at 72 minutes (IQR, 45-109 minutes) was shorter than that with CS, at 98 minutes (IQR, 64-135 minutes) (P = .048). Conclusion This post hoc analysis of the single-center SIESTA trial revealed that time from groin puncture to final angiographic result was shorter with patients under GA than that with patients under CS. © RSNA, 2017 Online supplemental material is available for this article.
