Abstract
Vertebrobasilar insufficiency (VBI) is a significant medical condition that results from a lack of adequate blood flow to the posterior circulation of the brain. The first-line treatment involves the use of antiplatelet therapy, but in cases where patients are not responsive to drug therapy, surgical management is the next viable option. In the past, open endarterectomy was the preferred surgical approach for treating critical VBI patients. However, due to its high mortality rates and severe peri-procedural complications, its usage has decreased. Instead, the endovascular approach has emerged as an alternative surgical option for resolving VBI. This review explores the current literature to assess the effectiveness of endovascular interventions in treating VBI patients. It also highlights potential complications and adverse effects associated with these treatments while identifying gaps in the current research that warrant further investigation. The review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to extensively search relevant literature on endovascular approaches for treating VBI patients on PubMed, BioMed Central, and ClinicalTrials.gov. The findings suggest that endovascular treatments have demonstrated significant technical success in treating VBI, with low mortality rates and minor adverse effects, such as intracranial hemorrhage and restenosis. The overall incidence of these complications is relatively low. Combining medical therapies with endovascular interventions has improved outcomes and reduced restenosis rates. However, there are methodological limitations and inconsistencies in the current literature that necessitate further investigation. Future research should focus on larger, randomized clinical trials and direct comparisons with other treatment options to obtain more conclusive evidence.

Microsurgical revascularization of a symptomatic proximal vertebral artery: pilot experiences from a single center. Front Neurol 2023; 14:1202565. [PMID: 37483445 PMCID: PMC10361759 DOI: 10.3389/fneur.2023.1202565] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2023] [Accepted: 06/26/2023] [Indexed: 07/25/2023] Open
Abstract
Background Vertebral artery stenosis and occlusion (VASO) is a high-risk factor for posterior circulation stroke. Post-stent restenosis and drug tolerance have facilitated the exploration of microsurgical vascular reconstruction. This study aims to evaluate the safety and efficacy of microsurgical reconstruction of the proximal VA. Methods Twenty-nine patients (25 men, aged 63.2 years) who had symptoms of posterior circulation ischemia underwent microsurgical revascularization for proximal VASO were retrospectively included in this study. Procedural complications and clinical and angiographic outcomes were reviewed. Results Twelve, three, and five patients underwent VA endarterectomy, artery transposition, or both, respectively; seven patients underwent vertebral endarterectomy plus stent implantation; and two patients failed surgery because of the difficult exposure of the VA and the occurrence of vascular dissection. The perioperative period-related complications included seven cases of Horner's syndrome, five cases of hoarseness, and one case of chylothorax. No cases of perioperative stroke or death were reported. The mean follow-up period was 28.4 (8-62 months). Most patients improved clinically; however, the vertebrobasilar ischemia symptoms did not decrease significantly in two patients during the follow-up. Moreover, follow-up imaging was performed in all the patients, and no signs of anastomotic stenosis were reported. Conclusion Microsurgical reconstruction is an alternative option that can effectively treat refractory proximal VASO disease and in-stent stenosis, with a high rate of postoperative vascular recirculation. Prospective cohort studies with larger sample sizes must be conducted to validate the above conclusions.

Abstract
OBJECTIVE To analyze hospital and long-term results of stenting of the V1 segment of the vertebral artery (VA) in the first hours after acute cerebral hemopoiesis/transient ischemic attack (stroke/TIA) in the vertebrobasilar territory (VT). MATERIAL AND METHODS The current retrospective study from 2012 to 2019 included 169 patients with hemodynamically significant stenosis of the V1 segment of the VA, who underwent emergency stenting in the first hours after the onset of stroke. The mean time between the development of stroke and correction was 368.5±129.8 minutes. The average time between admission to the medical institution and submission to the X-ray operating room was 89.2±10.7 minutes. VA stenting was performed through the transfemoral approach. In 118 cases (69.8%) a drug eluting stent was implanted, in 51 (30.2%) a bare metal stent was implanted. 90% of VA segment V1 stenosis was diagnosed in 48 patients before the onset of stroke. Of these, 33 received conservative therapy for vertebrobasilar insufficiency (VBI) for 2.5±1.0 months in anticipation of regression of the disease. The remaining 15 did not have VBI symptoms and did not need active drug treatment. Ultimately, within this sample, the time interval between the visualization of stenosis and the onset of stroke was 3.0±1.0 months. In 17 patients, stroke/TIA in VT became recurrent. The period between two neurological events was 1.5±0.5 months. Nine patients did not wait for the planned intervention due to the development of an adverse neurological event before the appointed date of hospitalization. The other 8 did not appear for the interventional correction on time due to subjective reasons and were again admitted to the medical facility on an urgent basis. RESULTS During the hospital follow-up period, no adverse cardiovascular events were recorded. When assessing the dynamics in the neurological status, there was a significant regression of the deficit by the time of discharge from the hospital. In the long-term follow-up period (38.2±20.4 months), a fatal outcome was recorded in 2.4% of cases (n=4). Non-fatal myocardial infaction was diagnosed in 5 patients (2.9%). Restenosis of the stent in the VA was visualized in 56 patients (33.1%). In 17 cases, it became symptomatic (10.0%). All patients underwent repeated stenting with a successful result of the procedure. CONCLUSION Emergency stenting of hemodynamically significant stenosis of the V1 segment of the VA in the acute period of stroke in VT is a safe and effective method of revascularization characterized by the absence of adverse cardiovascular events at the hospital stage of observation.

Variations of the extracranial segment of vertebral artery as a bleeding risk factor. Surg Radiol Anat 2021; 43:1735-1743. [PMID: 33890143 DOI: 10.1007/s00276-021-02748-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Accepted: 04/08/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND Standart interventional procedures such as screw instrumentation, aortic arch endovascular surgery and cervical nerve blockade may be of fatal risk due to anatomic reason of variations in the proximal part of the vertebral artery (VA). The aim of this study is to study the VA variations of the extracranial segments to evaluate the frequency of the incident to demonstrate the importance of clinical condition strategy. METHODS The prevalence of variations and morphometric measurements of the VA in three-dimensional computed tomographic angiography (3D-CTA) scans were studied. Total 400 VA was investigated for the aortic arch origin of the VA, diameter of the VA, its level of entry into the transverse foramen, the dominance sides, and related basilar artery course. RESULTS 3D-CTA radiographs of 200 Anatolian patients (120 men and 80 women with age range 17-90 years). In most cases (approximately 94%), both sides of VA were the first branch of subclavian artery. While all the right VAs was branched from the subclavian artery, 6% of the left VAs were branched from the aortic arch. 2/3 of them originated from the proximal of the subclavian artery and 1/3 from the distal. The VA which were originating from the proximal of the classical anatomic pattern tended to enter the transverse foramen more distally than C6 level. VAs with a different level of entry than C6 are left-sided and aortic arch originated (out of 8 cases 3 had a level of entry at C5 and 2 at C4). The outer diameter ranges of the prevertebral part of the VA of subclavian origin and left VA of aortic arch origin were 3.2-3.6 mm and 3.2-3.6 mm, respectively. While the diameters of the right and left VAs were almost the same in approximately 20% cases, the left VA was dominant in up to 60% of cases. A significant relationship was found between the side of the dominant VA and in the course of the basilar artery. CONCLUSIONS The relationship between the dominant side of VA and the course of the basilar artery of its own vessel has never been reported elsewhere. Such anatomical variations, routine preoperative 3D-CTA evaluation is mandatory to prevent the VA injury when C5-C2 instrumentation, anterior cervical decompression, cervical nerve blockade and aortic arch surgery are planned.

Abstract
BACKGROUND Ischemic stroke is the second leading cause of death in North Macedonia. Posterior circulation disease, caused by vertebral artery (VA) ostium (VAo) stenosis, is a common cause of ischemic stroke. We established a treatment approach using surgical revascularization of posterior circulation disease. In the present observational study, we assessed the outcome after surgical revascularization of the posterior circulation ischemia caused by VAo stenosis. METHODS A retrospective analysis of 20 consecutive patients who had undergone surgery from January 2017 to December 2019. The VA was accessed through a 3-cm incision in the upper medial clavicle. The corrective procedures consisted of resection and anastomosis (15 of 20), VA to subclavian artery transposition (16 of 20), endarterectomy (10 of 20), vein graft interposition techniques (4 of 20), and vein graft bypass (1 of 20). RESULTS The cohort included 9 acute cases. The mean patient age was 66.5 years (range 46-77). Of the 20 patients, 8 were women and 12 were men. Left-sided VA pathology was present in 75% of the cases. We observed rapid clinical improvement in 19 patients (95%). The total study period was 321 patient-months, with a median follow-up of 18 months (interquartile range, 5-24 months). One patient had died of an unknown cause after 12 months. During the follow-up period, 15 patients (75%) had reported permanent clinical improvement with no significant relapse of symptoms. CONCLUSIONS Minimally invasive surgical revascularization of the posterior brain circulation is a clinically effective therapeutic approach to manage ischemia caused by VAo stenosis. It can be performed safely, promote long-lasting symptom relief, and prevent recurrent strokes.

Abstract
Abstract
BACKGROUND
Surgical exposure of the V1 segment of the vertebral artery (V1-VA) at the lower neck may be necessary to address intravascular (atherosclerotic) and extravascular (external compression by neoplastic or degenerative) pathologies. The adjacent anatomy at the lower cervical region is complex and relatively unfamiliar to neurosurgeons compared to that of upper cervical levels. High-quality cadaveric images simulating the surgical approach to V1-VA are important for learning the relevant anatomy.
OBJECTIVE
To provide a brief stepwise depiction of the exposure of the V1-VA using a cadaveric surgical simulation.
METHODS
A cadaveric surgical simulation was performed on the left side to expose the V1-VA using the retrojugular and interjugular carotid approaches. The important adjacent anatomic structures en route to the V1-VA were identified.
RESULTS
A stepwise photographic demonstration of the surgical exposure of the V1-VA is provided.
CONCLUSION
Exposure of the V1-VA can be challenging and requires a clear anatomic understanding of the relevant anatomy. The present work attempts to facilitate this objective.
