NEVA IN AN I-TYPE ICA OCCLUSION WITH MANY SURPRISES:
LIVE CASE TRANSMISSION FROM iCureStroke 2022
NeVa™ 4.5 x 37 mm
This case was transmitted live during the iCureStroke 2022 meeting.
Full of surprises, the case started out with the patient presenting with signs of hemianopsia and relevant PCA-territory DWI restriction, suggesting an acute occlusion of the PCA. Albeit initial presentation, diagnostic angiography revealed an ipsilateral blockage of the ICA, mimicking a chronic occlusion, with filling of the ipsilateral MCA from the opposite side. The biggest surprise was the discovery of the fetal-type-PCA anatomic variant and the occlusion of the PCA origin, explaining the initial presentation with PCA-stroke symptoms.
The technical challenge was removing the high clot burden from the ICA without jeopardising the downstream territories, which remained fully intact. Any fragment loss would have compromised the MCA territory, worsening the patient outcome.
Watch the case in real-time as Prof Serdar Geyik and his team forge ahead despite the challenges. Take in the comments and recommendations of the iCureStroke meeting faculty as they discuss relevant evidence and statistics at each step.
