- Fig 1.
The graph shows the different data concerning antiplatelet therapy administered to patients treated with flow-diverter stents intraoperatively, up to 12 hours before the procedure, and during the first 6 postoperative months. Note that in some cases, this information was missing. These statistics are based on the available data. ASA indicates aspirin.

The graph shows the different data concerning antiplatelet therapy administered to patients treated with no flow-diverter stent up to 12 hours before the procedure, and during the first 6 postoperative months. Note that in some cases this information was missing. These statistics are based on the available data.
