Background: Posterior circulation strokes comprise approximately 20-25% of all strokes of ischemic origin. Strokes affecting this area carry a significantly higher risk for subsequent stroke or death as compared to anterior circulation strokes. Embolic protection device (EPD) use for carotid artery stenosis has translated into percutaneous interventions of proximal vertebral artery (VA) stenosis. However, the use of EPDs when treating intracranial lesions has yet to be studied and may not be feasible as the vessel caliber is frequently smaller than in existing devices. Objective: The aim of this study is to describe a proximal aspiration technique used during the treatment of intracranial VA and basilar artery (BA) atherosclerotic disease. Methods: Proximal embolic protection was utilized during the treatment of intracranial VA/BA stenosis with angioplasty and stenting in patients with medically refractory disease. Results: Three patients with severe symptomatic posterior circulation stenosis refractory to medical management were treated with angioplasty and stenting utilizing proximal aspiration. Pre- and post-treatment angiograms and MRIs were compared. Treated vascular stenoses were significantly improved, without new neurological deficits or ischemic injury identified on imaging. Conclusions: The proposed technique of proximal embolic protection may help overcome the challenge of embolus propagation inherent to the treatment modality that was encountered during the treatment of intracranial VA/BA stenosis.

Objective — to optimize the results of endovascular treatment of stenotic pathology of brachiocephalic arteries. Materials and methods. The results of surgical treatment of 112 patients, among whom there were 79 (70.5 %) men and 33 (29.5 %) women aged from 28 to 86 years with symptomatic stenotic lesions of brachiocephalic arteries treated in the neurosurgical department of the Zaporizhzhia regional hospital in the period from 2010 to 2018 were analyzed. Observations were divided into three groups depending on the localization of the defeat: internal carotid artery — 74 (66 %) cases (predominant stenosis of the mouth of the ICA (n = 71)), vertebral artery — 25 (22.4 %), a portion of the subclavian artery or brachiocephalic trunk — 13 (11.6 %). All patients underwent MRI of the brain in the preoperative period, as well as in 45 (40 %) cases of CTangiography. In all cases prior to surgery invasive angiography was performed with an assessment of the state and anatomy of the brachiocephalic and intracranial arteries, as well as the possibilities of collateral blood flow. Results. In the first group, which was conducted carotid stenting embolic protection device was used in 72 (97.2 %) cases. In the second group, distal protection device were used twice 2 (8 %) in the resolution of extended stenoses of the dominant vertebral artery mouth. In the third group, the distal protection device was used in 1 (7.7 %) case for stenting the critical extended stenosis of the brachiocephalic trunk with the transition to common carotid artery. Complications were noted in 9 observations. In one case there was a development of ischemic stroke, intraoperatively, in a patient with an echeloned lesion of the intracranial basin of a stenting internal carotid artery, probably against a background of hypotension of the stent developed during implantation. In 8 (7.1 %) cases the formation of the hematoma of the puncture site of the femoral artery was noted. Conclusions. The use of embolic protection device is mandatory in standard carotid stenting. The choice of method of protection depends on the severity of stenosis, as well as the individual features of collateral blood flow. When stenting subclavian artery, brachiocephalic trunk and vertebral artery, in some cases it is justified to use distal protection devices, the latter increases the safety of the operation.

Introduction: One of the most feared complications of carotid revascularization, including carotid artery stenting (CAS), is peri-procedural ischemic stroke. Several studies suggest that the use of a distal embolic protection device (EPD), as well as over-sized pre- and post-stenting balloon angioplasty, may increase the risk of dislodgement of atheromatous plaque in patients undergoing CAS. The CREST trial, that mandated the use of an EPD, had a peri-procedural ischemic stroke rate of 4.1%. We hypothesize that our technique of stenting without the use of an EPD and sub-maximal angioplasty will have a low risk of peri-procedural complications. Methods: A retrospective review was conducted of consecutive cases of ICA stenting without use of an embolic protection device between January 2012 and June 2020 at a Canadian stroke centre. Data was extracted from the patient electronic medical record and Picture Archives and Communications Systems (PACS). Both symptomatic and asymptomatic CAS cases were included. Results: A total of 220 patients were included in the study, with a median age of 70 years (range 39-93 years), and 83 patients (38%) were female. The vast majority of patients were symptomatic (216 patients [98%]). A large portion of patients had a contralateral ICA occlusion or near occlusion (56 patients [25%]). In the majority of cases, a Precise Cordis RX carotid stent (Cordis) was placed. There were four patients with peri-procedural ischemic strokes (1.8%), with two occurring 8-30 days after stenting. There was one case of acute stent occlusion associated with an ischemic stroke. Two patients (less than 1%) had hyperperfusion syndrome after CAS. Median length of stay following the procedure was one day. Conclusions: In this single centre series, the peri-procedural risks of CAS without using an EPD are low. The ischemic stroke rate is less than 2%, lower than what has been reported in large randomized controlled trials using embolic protection.
