Eligibility CriteriaInclusion Criteria:Patients with acute stroke considered for thrombectomy and meeting the following inclusion criteria included:
1. the patient is ≥ 18 years
2. the patient has a CT angio verified embolization * and / or a NIHSS scores ** ≥ 10 (R) or 14 (L) depending on the side engagement
3. embolectomy (= groin puncture) started <8 hours after symptom onset
- Embolus in one of the following arteries: internal carotid artery, anterior cerebral (A1 segment), cerebri media (M1 segment) and proximal cerebri media branches (M2 segment).
- NIHSS (National Institutes of Health Stroke Scale). Patients with embolus in left hemisphere circulation require ≥ 14 points, while patients with embolus in the right hemisphere circulation require ≥ 10 points. This is because occlusion on the right side does not usually cause aphasia, a symptom that usually leads to higher total score of NIHSS.
Exclusion Criteria1. the patient must receive general anesthesia, for medical reasons, according to the responsible anesthesiologist
2. the patient cannot receive general anesthesia, for medical reasons, according to the responsible anesthesiologist
3. the patient has an embolization of posterior brain vessels
4. CT-confirmed intracerebral hemorrhage
5. spontaneous recanalization or spontaneous neurological improvement
6. any other reason that does not allow embolectomy (co-morbidities)
7. premorbid MRS ≥ 4
