Event Description
A journal article was submitted for review titled: "carotid artery stenting in patients with contralateral carotid occlusion using a combined protection method".The aim of this study was to compare the clinical characteristics, treatment outcomes, and adverse events in patients with and without contralateral carotid occlusion (cco) to assess the safety of the dual protection and blood aspiration method of carotid artery stenting (cas) for carotid artery stenosis-contralateral carotid occlusion (ics-cco).The study was a retrospective single-center study which assessed 218 patients with internal carotid artery stenosis who underwent carotid artery stenting using the dual protection (simultaneous flow reversal and distal filter) and blood aspiration method.The patients were divided into two groups: ics and contralateral carotid occlusion (n = 11) (cco group) and patients with ics and no contralateral carotid occlusion (n = 207) (non-cco group).The mean degree of stenosis was 72.3% ± 16.2% in the cco group and 73.3% ± 18.9% in the non-cco group.During the procedure a 9fr non mdt occlusion balloon guide catheter was introduced into the common carotid artery via the femoral artery.Next, a guardwire temporary occlusion and aspiration system was introduced into the external carotid artery.The proximal end of the 9fr occlusion balloon guide catheter was connected to the 4fr sheath and was inserted into the femoral vein via the blood filter.Under flow reversal, a non mdt filter wire was placed into the most cranial part of the cervical internal carotid artery (ica).Under this dual protection, pre-dilation was performed, and a self-expanding non mdt stent was deployed.Post-dilation was performed with an angioplasty balloon with a diameter similar to that of the normal distal ica.An export advance aspiration catheter was then placed between the proximal end of the stent and the distal filter, and blood was aspirated several times from the ica.Anticoagulant medication was continued for 12 hours after cas.Dual-antiplatelet drugs were administered for the first 3 months post-procedure, followed by a single antiplatelet drug.Technical success was achieved in all cases.In the 11 patients in the cco group the following events were reported: intraoperative transient neurological symptoms (n=2), hypotension (n=5), dwi hyperintensities (n=3), intraoperative capture debris (n=2), restenosis (n=1).There were no cases of access related complications, major adverse events, minor strokes, and tia in the cco group.In the 207 patients in the non-cco group the following events were reported: intraoperative transient neurological symptoms (n=34), hypotension (n=63) and bradycardia (n=13).For the non-cco group, access-related complications (n=2), major adverse events (n=1), major stroke (n=1), minor strokes (n=5), tia (n=5), dwi hyperintensities (n=63), intraoperative capture debris (n=73), and restenosis (n=9) occurred.
