Investigations

Labs:

CT:

  • Hyperdensity in the M1 Segment of the Right Middle Cerebral Artery, with no other signs suggestive of an Ischemic Stroke noted.
    Provisional diagnosis of Acute Ischemic Stroke secondary to occlusion of the M1 was made
    Patient was treated with intravenous Tissue Plasminogen Activator (tPA) at 1 h 54 min after symptom onset

MRI:

  • Multimodal MRI Scan completed at 3 h 09 min after symptom onset demonstrated Ischemic Changes confined predominantly to the Right Middle Cerebral Artery
  • Perfusion-weighted MRI showed larger perfusion abnormality, indicating presence of a substantial volume of potentially salvageable penumbral tissue.
  • Time-of-flight magnetic resonance angiography showed a loss of signal in the Right Internal Carotid Artery and Middle Cerebral Artery.

Cerebral Angiography

  • Cerebral angiogram performed post MRI demonstrated Occlusive Thrombus extending from the Right Internal Carotid Artery Origin through the Right Middle Cerebral Artery Trunk.
  • Recanalization was attempted by Endovascular Thrombectomy performed 4 h 19 min after symptom onset

Medical Management

Thrombolysis & Endovascular Mechanical Thrombectomy:

  • Discussed with Family & Patient
  • tPA Prescribed and Initiated within 1hr 54mins After Onset Symptoms
  • Endovascualr Thrombectomy Initiated at 3hr 

Stroke Unit:

  • Admitted to Acute Stroke Unit
  • 24 Hour Monitoring
  • MDT Referral Received within 24 Hours - OT, SLT & PT
