Results of the Use of Two Stentrievers Simultaneosly Compared With One as a Primary Treatment in Acute Ischemic Stroke
Stroke, Thrombectomy, Arterial Occlusive Diseases
About this trial
This is an interventional treatment trial for Stroke focused on measuring Stroke, Double Stentriever, Thrombectomy
Eligibility Criteria
Inclusion Criteria: A new disabling focal neurological deficit compatible with acute cerebral ischemia. Any age. Informed consent obtained from the patient or representative. NIHSS score ≥ 6. Pre-existing functional clinical status less than or equal to 2 according to the mRS clinical scale. Maximum time of 24 hours from symptom onset to arterial puncture. • TICI 0-1 in the diagnosed TICA (terminal internal carotid artery) , MCA (middle cerebral artery), and BA( basilar artery confirmed by angioCT and angiography). ASPECTs score on baseline CT greater than or equal to 6. In cases where it is indicated, prior intravenous fibrinolysis will be administered according to the protocols of each center. Exclusion Criteria: Those described in the usual protocols for mechanical thrombectomy of each hospital. Pre-existing functional clinical status greater than 2 according to the mRS clinical scale Patients with tandem lesions of dissection or arteriosclerotic origin located in the extracranial internal carotid artery. Initiation of treatment with a different technique than the one described. Inability to use a proximal balloon guide catheter. Use of aspiration catheter. Intracranial atherosclerotic plaque as the cause of occlusion. Advanced or terminal disease with a life expectancy of less than 6 months. Patient who is participating in another study that may affect this one. ASPECTS score less than or equal to 6 on baseline CT. Evidence of significant hemorrhage or mass effect with midline shift on baseline CT. Patients with occlusions in multiple vascular territories. Evidence of intracranial tumor (except for small meningiomas)
