Developments in carotid artery disease diagnosis and treatment have always been an important component of the VEITHsymposium programs and there will be sessions focusing on this critical area of patient management throughout the entire meeting.
The session will be moderated by Bruce A. Perler, MD, and L. Nelson Hopkins, MD, and include presentations on the value of using biomarkers of brain injury associated with carotid interventions, and how to assess and treat such adverse events as cerebral hyperfusion syndrome and intracranial artery dissection, as well as best medical treatments for carotid patients.
Of particular interest, there will be a debate Tuesday on the need for completion imaging with duplex or angiography with Hans-Henning Eckstein, MD, PhD, and R. Clement Darling III, MD.
Presentations will also address some of the latest treatment techniques for carotid artery disease. For example, on Wednesday morning, Norman H. Kumins, MD, of the Cleveland Medical Center, will present a study on the duration of blood flow reversal during transcarotid artery revascularization (TCAR), an “increasingly popular alternative to carotid endarterctomy and transfemoral artery carotid stenting,” which is designed to provide increased neuroprotection during the placement and angioplasty of the carotid stent. They analyzed the relationship between the length of TCAR flow reversal time (FRT) and major adverse events in 307 patients who underwent TCAR at four high-volume institutions. They separated patients into short (3-7minutes); medium(8-12 minutes); and long group (greater than 12 minutes) FRT. They designated a subset of the long group patients of those with greater than or equal to 20 or more minutes FRT, which they defined as the very long group. The stroke, myocardial infarction, and death rates at 30 days were assessed for all patients and were compared them between groups.
Dr. Kumins will detail how the overall stroke rate was 1.3%, with all strokes considered minor, and all patients showing full recovery. The four strokes occurred in patients with FRT of 6, 7, 11, and 12 minutes, showing no difference in the composite stroke/death or stroke/death/MI rates among the groups, the researchers indicated.
Dr. Kumins will discuss how flow reversal time does not affect stroke rates in patients undergoing TCAR, and suggest that operators should focus on the technical aspects of the procedure during flow reversal rather than being concerned about the amount of FRT.
