Background Recent trials confirmed the efficacy and safety of endovascular thrombectomy in patients with low Alberta Stroke Program Early Computed Tomography Score (ASPECTS); however, evidence in tandem lesions is limited. This study evaluates endovascular thrombectomy safety and efficacy in patients with acute large‐vessel occlusion with tandem lesions, stratified by baseline ASPECTS. Methods and Results We conducted a retrospective analysis of data from 16 centers. Inclusion criteria included the following: age ≥18 years, anterior circulation tandem lesions, endovascular thrombectomy

Background Despite thrombectomy having become the standard of care for large‐vessel occlusion strokes, acute endovascular management in tandem occlusions, especially of the cervical internal carotid artery lesion, remains uncertain. We aimed to compare efficacy and safety of acute carotid artery stenting to balloon angioplasty alone on treating the cervical lesion in tandem occlusions. Similarly, we aimed to explore those outcomes’ associations with technique approaches and use of thrombolysis. Methods and Results We performed a systematic review and meta‐analysis to compare functional outcomes (modified Rankin Scale), reperfusion, and symptomatic intracranial hemorrhage and 3‐month mortality. We explored the association of first approach (anterograde/retrograde) and use of thrombolysis with those outcomes as well. Two independent reviewers performed the screening, data extraction, and quality assessment. A random‐effects model was used for analysis. Thirty‐four studies were included in our systematic review and 9 in the meta‐analysis. Acute carotid artery stenting was associated with higher odds of modified Rankin Scale score ≤2 (odds ratio [OR], 1.95 [95% CI, 1.24–3.05]) and successful reperfusion (OR, 1.89 [95% CI, 1.26–2.83]), with no differences in mortality or symptomatic intracranial hemorrhage rates. Moreover, a retrograde approach was significantly associated with modified Rankin Scale score ≤2 (OR, 1.72 [95% CI, 1.05–2.83]), and no differences were found on thrombolysis status. Conclusions Carotid artery stenting and a retrograde approach had higher odds of successful reperfusion and good functional outcomes at 3 months than balloon angioplasty and an anterograde approach, respectively, in patients with tandem occlusions. A randomized controlled trial comparing these techniques with structured antithrombotic regimens and safety outcomes will offer definitive guidance in the optimal management of this complex disease.
