- FIG 1.
Oblique anterior-posterior-projection DSA images with a right ICA injection during a mechanical thrombectomy procedure. An 11-month-old infant (patient 4 in the Online Supplemental Data) with congenital cardiac disease had reduced movement of the left upper limb and face after waking from a nap. CTA demonstrated a right MCA proximal M2 occlusion. A, Subocclusive thrombus involving the proximal aspect of the right MCA superior M2 division (white arrow). B, Following a single-pass mechanical thrombectomy with a 3-mm-diameter stent retriever, angiographic vasospasm was present in the recanalized vessel segment (white arrow). C, Vasospasm resolution was noted after intra-arterial infusion of verapamil (1.5 mg) via the right ICA 4F catheter. The ped-mRS score at 3 months was 1.
- FIG 2.
A 3-year-old patient (patient 3 in the Online Supplemental Data) developed fluctuating weakness of the left upper limb (Ped-NIHSS 3) after recent cardiac surgery for cor triatriatum. A, Axial CT angiogram demonstrates a filling defect in the right MCA distal M1 segment (black arrow). B, Lateral-projection DSA image with a right ICA injection demonstrates interval migration of the thrombus to the right MCA posterior (perirolandic) mid-M2 division (white arrow). After multidisciplinary discussion regarding the potential long-term disabling impact of a perirolandic infarct, it was agreed to proceed to the mechanical thrombectomy. C, After 2 passes with a 3-mm-diameter stent retriever, there was successful recanalization of the right perirolandic posterior M2 division. The ped-mRS score at 3 months was 0.
