Tandem occlusion, that is, intracranial and extracranial occlusion at the same time, accounts for 10% to 20% of all large-vessel occlusion strokes
The existence of cervical internal carotid artery (ICA) stenosis has brought technical challenges to the operator when using EVT to treat tandem occlusive disease
Based on the available evidence, the American Heart Association/American Stroke Association believes that the treatment of cervical ICA during EVT is reasonable (level IIb evidence)
The lack of randomized trials and the contradictory results of observational studies have created a state of uncertainty, which was also emphasized in the recent international survey on acute treatment options for tandem occlusive disease
The patient data came from the French prospective multicenter observational ETIS (endovascular treatment of ischemic stroke) and the international TITAN (thrombectomy of tandem lesions) registry
They enrolled a total of 603 patients, of which 341 received acute cervical ICA stent treatment
In the inverse probability analysis adjusted for the treatment weighted propensity score, the stent group had higher favorable outcomes (adjusted odds ratio, 1.
However, the probability of any intracerebral hemorrhage in the stent group was higher (adjusted odds ratio, 1.
Subgroup analysis showed that according to the heterogeneity of the disease type (atherosclerosis and dissection; heterogeneity P=0.
According to the heterogeneity of the disease type (atherosclerosis and dissection; P=0.
For patients with acute carotid artery stent treatment for tandem occlusive stroke, although the probability of intracerebral hemorrhage is higher, the good result of 90 days is higher;
