NCT05930145

Brief Summary

Several studies have demonstrated that simultaneous treatment with two stentrievers (STs) as rescue treatment is very effective, with high recanalization rates even in this group of patients where other revascularization techniques have failed. There has been no observed increase in hemorrhagic complications. Recently, a prospective study has been published where treatment with two ST has been shown to be effective and safe if used as a first-choice treatment (not as rescue) with a successful recanalization rate (eTICI 2c/3) after the first pass of 69%. These results have been reinforced after the publication of a randomized study that confirms, in vitro, the superiority of using two ST over one.

Outcome Measures

Primary Outcomes (2)

  • EFFECTIVENESS OBJECTIVE: Complete recanalization on first pass

    Comparison of the complete recanalization rate in the first pass in the double stent group compared to the single stent group, defined as TICI greater than 2c on the Thrombolysis in Cerebral Infarction scale (eTICI scale).

    90 days

  • SAFETY OBJECTIVE: Intracerebral hemorrhage.

    Rate of patients with symptomatic intracranial hemorrhage (neurological deterioration in National Institutes of Health Stroke Scale \[NIHSS\] \>4) at 24h observed between both groups and, fundamentally, evaluated by CT.

    24 hours

Secondary Outcomes (12)

  • Intervention success.

    During the procedure

  • Complications related to the intervention.

    During the procedure

  • Embolism in new territories.

    During the procedure

  • Number of passes with the devices.

    During the procedure

  • Procedure time.

    During the procedure

  • +7 more secondary outcomes

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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.

You may not qualify if:

  • 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)
