Mechanical thrombectomy using a Solitaire stent retriever in the treatment of pediatric acute ischemic stroke

Restricted access

In Brief

The authors conducted a clinical study on the safety and effectiveness of mechanical thrombectomy using a Solitaire stent retriever for pediatric acute ischemic stroke (AIS). This is an important exploration for the treatment of pediatric AIS.

ABBREVIATIONS ACA = anterior cerebral artery; AIS = acute ischemic stroke; CTA = CT angiography; ICA = internal carotid artery; MCA = middle cerebral artery; mRS = modified Rankin Scale; mTICI = modified Thrombolysis In Cerebral Infarction; NIHSS = National Institutes of Health Stroke Scale; rt-PA = recombinant tissue plasminogen activator.

    Case 3. A: Digital subtraction angiography (DSA) of the right ICA showed a complete ICA occlusion. B: After two applications of mechanical thrombectomy, the MCA was recanalized and a limited stenosis was found at the MCA-M1 segment (arrow). C: A 2 × 15 mm balloon (arrows) was used to dilate the stenosed segment. D: The stenosis of the MCA M1 segment was relieved after the balloon dilation. E: The MR angiography showed MCA patency 1 week after the operation. F: High-resolution MRI showed the vessel wall obviously thickened (arrows), which indicated MCA dissection.

    Case 7. A: Emergency CT scan showed the high-density sign of the right ACA (arrow). B: DSA of the right ICA confirmed the ACA origin occlusion (arrow). C: The right ACA achieved an mTICI grade 3 recanalization after two applications of mechanical thrombectomy. D: The postoperative CT image showed a small amount of subarachnoid hemorrhage (arrowhead). E: The head MR image showed a large infarction area of the right cerebrum 18 hours later. F: Brain CT showed right cerebral hernia 36 hours later.
