Conscious Sedation versus General Anesthesia during Endovascular Acute Ischemic Stroke Treatment: A Systematic Review and Meta-Analysis EVIDENCE-BASED MEDICINE LEVEL 1
CONCLUSIONS: Patients with acute ischemic stroke undergoing intra-arterial therapy may have worse outcomes with general anesthesia compared with conscious sedation. However, the difference in stroke severity at the onset may confound the comparison in the available studies; thus, a randomized trial is necessary to confirm this association.

Interpretation of Brain CT Scans in the Field by Critical Care Physicians in a Mobile Stroke Unit
CONCLUSIONThis pilot study shows that anesthesiologists trained in prehospital critical care may effectively assess cerebral CT scans in an MSU, and determine if there are radiological contraindications for thrombolysis.

The Impact of Conscious Sedation versus General Anesthesia for Stroke Thrombectomy on the Predictive Value of Collateral Status: A Post Hoc Analysis of the SIESTA Trial INTERVENTIONAL
CONCLUSIONS: The sedation mode, conscious sedation or general anesthesia, did not influence the predictive value of collaterals in patients with large-vessel occlusion anterior circulation stroke undergoing thrombectomy in the SIESTA trial.

Improving mechanical thrombectomy time metrics in the angiography suite: Stroke cart, parallel workflows, and conscious sedation.
Conclusions Use of a stroke cart, parallel workflows by neurointerventionalists, technologists, and nursing staff, and use of conscious sedation may be useful to other institutions in efforts to improve procedural times. PMID: 29145742 [PubMed - as supplied by publisher]

Dose reference levels and clinical determinants in stroke neuroradiology interventions
ConclusionsStroke dose RLs introduced in this work promote the optimisation of patient doses. Male gender, number of passages and success of recanalisation are independent key parameters affecting patient dose.Key Points• Stroke dose RLs derived in terms of total DAP (162 Gy cm2), Ka,r(854 mGy), FT (42 min) and NI (559) will help optimise the radiation safety of patients treated with mechanical thrombectomy.• Male gender (relative dose multiplier 1.31; 95% CI 1.12–1.45), number of passages (RDM 1.22 per passage; 95% CI 1.10–1.22) and success of recanalisation TICI score> 2b (RDM 0.52, 95% CI 0.55 –0.80) are in...

Association of local anesthesia versus conscious sedation with functional outcome of acute ischemic stroke patients undergoing embolectomy.
CONCLUSION: Functional outcome of acute ischemic stroke patients undergoing embolectomy appears to be similar for patients receiving local anesthesia and conscious sedation. This similarity may be beneficial to a future study comparing general anesthesia to local anesthesia and conscious sedation. The use of local anesthesia or conscious sedation does not significantly impact hemodynamic status. PMID: 32375517 [PubMed - as supplied by publisher]

Stroke : How can "time is brain" be translated into clinical practice?
DISCUSSION: Measures to optimize therapy times are mostly organizational and cause little or no extra costs. When implemented these measures can lead to a significant improvement in therapy times and functional patient outcome. PMID: 26728155 [PubMed - as supplied by publisher]

Radiation exposure in endovascular stroke treatment of acute basilar artery occlusions —a matched-pair analysis
ConclusionEndovascular stroke treatment of basilar artery occlusions is associated with a higher radiation exposure compared with treatment of middle cerebral artery occlusions.

Worldwide anaesthesia use during endovascular treatment for medium vessel occlusion stroke
CONCLUSIONS: Anaesthesia approaches in MeVO EVT vary across world regions and patient and physician factors. Most physicians in this survey preferred to start with local anaesthesia or conscious sedation and convert to GA if necessary.PMID:34665059 | DOI:10.1177/15910199211041487

Mechanical Thrombectomy in Acute Stroke: Prospective Pilot Trial of the Solitaire FR Device while Under Conscious Sedation INTERVENTIONAL
CONCLUSIONS: In acute ischemic stroke, mechanical thrombectomy while under conscious sedation is feasible in a large percentage of cases (86.1%) and is associated with a short procedure delay and a high percentage of good functional outcomes at 3 months (61.1%).

A comparison of four PET tracers for brain hypoxia mapping in a rodent model of stroke
Conclusions: This study suggests further development of these radiotracers as hypoxia markers for ischemic stroke may not be warranted.

Even Small Decreases in Blood Pressure during Conscious Sedation Affect Clinical Outcome after Stroke Thrombectomy: An Analysis of Hemodynamic Thresholds INTERVENTIONAL
CONCLUSIONS: A ≥10% mean arterial pressure drop from baseline is a strong risk factor for poor outcome in a homogeneous population of patients with stroke undergoing thrombectomy under sedation. This threshold could guide hemodynamic management of patients during sedation and general anesthesia.

Impact of Anesthesia on the Outcome of Acute Ischemic Stroke after Endovascular Treatment with the Solitaire Stent Retriever INTERVENTIONAL
CONCLUSIONS: In this single-center study, the anesthetic management during stent retriever thrombectomy with general anesthesia or conscious sedation had no impact on the outcome of patients with large-vessel occlusion in the anterior circulation.

The anesthetic approach for endovascular recanalization therapy depends on the lesion site in acute ischemic stroke
ConclusionsThe VLSM analysis showed associations between GA and ischemic lesions in the left hemispheric middle cerebral artery territory and posterior circulation areas including the thalamus that are known to cause neurologic deficits, such as aphasia or compromised vigilance, in AIS-patients with EVT. Our data suggest that higher disability, clinical impairment due to neurological deficits like aphasia, or reduced alertness of affected patients may influence the physician ’s decision on using GA in EVT.
