Abstract
The purpose of this study was to present a meta-analysis on the safety and efficacy of different endovascular modalities when treating vertebral artery dissections, since ideal treatment remains controversial. We performed a meta-analysis of 39 retrospective studies involving different treatment modalities for vertebral artery dissections in adults and obtained weighted pooled proportional outcome and mortality ratios with a random effects model. Overall, 75.11 % (confidence interval (CI) 68.89–80.84, I 2 66.89 %) had excellent outcomes, 10.10 % (CI 6.83–15.56, I 2 65.64 %) had good outcomes, and 13.70 % (CI 9.64–18.35, I 2 60.33 %) had poor outcomes. Postoperative complications occurred in 10.52 % (CI 6.87–14.84, I 2 62.48 %), with 2.73 % (CI 1.64–4.10, I 2 0.0 %) exhibiting vasospasm, 3.03 % (CI 1.88–4.46, I 2 0.0 %) experiencing postoperative rebleeding, and 6.31 % (CI 3.57–9.76, I 2 60.92 %) showing ischemia. Overall mortality was 8.69 % (CI 6.13–11.64, I 2 33.76 %). When compared to these overall ratios, different treatment modality subgroups did not differ significantly, except for the proximal occlusion group, with poor outcome ratio = 26.96 % (difference 13.26, CI 0.02–30.04, p = 0.0403) and mortality ratio = 21.36 % (difference 12.67, CI 0.94–28.86, p = 0.0189). Different endovascular treatment modalities are comparatively safe and effective in the management of vertebral artery dissection. Their reduced operative time, minimal invasiveness, and overall safety render them a suitable option for intervention-amenable dissections.

The authors described the results of a meta-analysis on 39 studies regarding endovascular treatments for 637 patients with vertebral artery (VA) dissection and showed the efficacy and safety of these modalities. This paper is suggestive and has clinical relevance since the number of cases has been increased by the introduction of magnetic resonance imaging into a diagnostic tool in acute stroke and also endovascular treatment has been considered as an alternative therapy to open surgery in VA dissection especially in cases with subarachnoid hemorrhage (SAH).
This study provided detailed clinical outcomes and angiographic results in VA dissections treated by different endovascular techniques, including stenting, stent-assisted coiling, parent vessel occlusion by means of coiling or balloons, balloon-assisted coiling, and proximal occlusion. The majority of the lesions had an intracranial location, and the most common clinical presentation was SAH followed by ischemia and other symptoms. Posterior inferior cerebellar artery involvement was seen in about 15 %. This paper showed the superiority of endovascular treatments in VA dissections; however, only proximal occlusion could not achieve good clinical outcome and angiographic improvement compared to other treatments. Proximal occlusion was more likely to be applied to SAH patients, and as pointed out, this has been performed in technically complex lesions such as those involving branches or difficult to treat with coils or balloons. It has been known that the cure of VA dissention would be to eradicate the lesion from the arterial bloodstream by trapping with or without bypass. Therefore, proximal occlusion cannot preclude the dissection from being reruptured or regrown [1]. Recently, the pipeline embolization device was introduced as the flow-diverting device intended to exclude the aneurysm hemodynamically from the parent artery preserving blood flow through covered arterial branches [2–3]. This new device might achieve higher curability with less ischemic complications for the lesion involving branches. The reduced operative time, minimal invasiveness, and overall safety render endovascular treatment a suitable option for intervention-amenable dissections.
Meanwhile, unruptured VA dissections usually have a benign nature [4] and have a tendency to be treated with conservative therapy. This paper did not show any evidence revealing endovascular treatment is superior to conservative treatment. Further study is necessary to determine the suitable management for unruptured VA dissection.
