Left Hemisphere Stroke Endovascular Treatment
Procedure:
General Anaesthetic. Sterile technique. Right 8 Fr CFA retrograde sheath. Systemic heparinisation.
Diagnostic angiography confirmed left extracranial ICA occlusion and critical right extracranial ICA stenosis. Major cerebral supply from enlarged right vertebral artery. Left M1 occlusion also demonstrated.
8 Fr Merci balloon guide catheter to left CCA. Rebar 27 microcatheter and Synchro standard microguide wire through ICA occlusion, with the guide catheter subsequently advanced into the ICA. Microcatheter and wire through M1 occlusion into M2 origin. Solitaire (4 x 20 mm) deployed from distal M1 back into terminal ICA. Forward flow achieved. Solitaire retrieved under suction delivering a large amount of clot both on the device and within the aspirate. Good intracranial flow demonstrated.
EZ-filter wire deployed in distal extracranial ICA and the 8 Fr guide catheter retracted into the CCA under suction, again delivering thromboembolus. Filling defects were noted within the filter wire consistent
with embolic debris. A single bolus of 3 mg of Verapamil was given IA. The ICA origin stenosis was angioplastied using a 5 mm balloon. A 9 x 40 mm Carotid Wall Stent (Stryker) was deployed with post dilatation with the 5 mm balloon.
