Little is known about the implications of multivessel occlusions (MVO) in large vessel occlusion stroke patients who undergo endovascular treatment (EVT).
We report data from the MR CLEAN Registry: a prospective, observational study on all stroke patients who underwent EVT in the Netherlands (March 2014-November 2017). We included patients with an intracranial target occlusion in the anterior circulation. An MVO was defined as an MCA occlusion (M1/M2) or intracranial ICA/ICA-T occlusion, with a concurrent second occlusion in the ACA or PCA territory confirmed on baseline CTA. To compare outcomes, we performed a 10:1 propensity score matching analysis with a logistic regression model including potential confounders. Outcome measures included 90-day functional outcome (modified Rankin Scale, mRS) and mortality.
Of 2946 included patients, 71 patients (2.4%) had an MVO (87% concurrent ACA occlusion, 10% PCA occlusion, 3% ⩾3 occlusions). These patients were matched to 71 non-MVO patients. Before matching, MVO patients had a higher baseline NIHSS (median 18 vs 16, = 0.001) and worse collateral status (absent collaterals: 17% vs 6%, < 0.001) compared to non-MVO patients. After matching, MVO patients had worse functional outcome at 90 days (median mRS 5 vs 3, cOR 0.39; 95%CI 0.25-0.62). Mortality was higher in MVO patients (46% vs 27%, OR 2.11, 95%CI 1.24-3.57).
MVOs on baseline imaging were uncommon in LVO stroke patients undergoing EVT, but were associated with poor functional outcome.
对于接受血管内治疗 (EVT) 的大血管闭塞性卒中患者，多血管闭塞 (MVO) 的影响知之甚少。
我们报告了 MR CLEAN 登记处的数据：这是一项对荷兰所有接受 EVT 的卒中患者进行的前瞻性、观察性研究（2014 年 3 月至 2017 年 11 月）。我们纳入了前循环颅内靶血管闭塞的患者。MVO 的定义为 MCA 闭塞（M1/M2）或颅内 ICA/ICA-T 闭塞，同时在基线 CTA 上证实存在第二处 ACA 或 PCA 区域的闭塞。为了比较结果，我们使用包含潜在混杂因素的逻辑回归模型进行了 10:1 的倾向评分匹配分析。结局指标包括 90 天的功能结局（改良 Rankin 量表，mRS）和死亡率。
在 2946 例纳入患者中，71 例（2.4%）存在 MVO（87%并发 ACA 闭塞，10%PCA 闭塞，3% ⩾3 处闭塞）。这些患者与 71 例非 MVO 患者相匹配。匹配前，MVO 患者的基线 NIHSS 更高（中位数 18 分比 16 分，=0.001），侧支循环状态更差（无侧支循环：17%比 6%，<0.001）。匹配后，MVO 患者在 90 天时的功能结局更差（中位数 mRS 5 分比 3 分，cOR 0.39；95%CI 0.25-0.62）。MVO 患者的死亡率更高（46%比 27%，OR 2.11，95%CI 1.24-3.57）。
在接受 EVT 的 LVO 卒中患者中，基线影像学上的 MVOs 并不常见，但与不良的功能结局相关。
