Optical coherence tomography valuable in carotid stenting

The safety and feasibility of optical coherence tomography (OCT) of the carotid arteries is supported by a study published recently in the Journal of Endovascular Therapy.1

25 patients undergoing carotid artery stenting also underwent OCT before stent deployment, immediately after stent placement, and following postdilation of the stent. The OCT technique had a success rate of 97.3%, and no complications occurred for the patients during the procedures or in the hospital.

Through the use of OCT in this study, physicians were able to see, among other details, rupture of the fibrous cap, plaque prolapse, and stent malapposition in patients.

As the authors of the accompanying commentaries2,3 note, future applications could reveal further details that increase our understanding of carotid stenting and influence clinical policies regarding its use.

Carotid artery stenting has not reached its predicted potential, the authors say, in part owing to lack of reimbursement in the United States and mixed results from European trials. OCT may provide evaluation of critical aspects of carotid artery stenting. Additionally, more evidence from OCT clinical research could help health authorities realise the value of the carotid artery stenting procedure.
