Abstract
BACKGROUND AND PURPOSE Because children often have lifelong morbidity after stroke, there is considerable enthusiasm to pursue mechanical thrombectomy in childhood stroke based on literature reports. However, current published data may reflect inconsistent reporting and publication bias, which limit the ability to assess safety and efficacy of mechanical thrombectomy in childhood stroke. METHODS This retrospective cohort study compared reporting quality and clinical outcomes for mechanical thrombectomy between a trial-derived cohort of 42 children treated with mechanical thrombectomy for acute stroke at study sites and 133 patients reported in the literature. National Institutes of Health Stroke Scale at baseline, 24 hours after mechanical thrombectomy, and at discharge were compared between study site patients and literature patients. Odds ratios (ORs) were used to compare reporting frequencies. Proportional odds logistic regression was used to compare outcomes. RESULTS Premechanical thrombectomy National Institutes of Health Stroke Scale was available in 93% of study patients compared with 74% of patients in the literature (OR, 4.42 [95% CI, 1.47-19.89]). Postmechanical thrombectomy National Institutes of Health Stroke Scale was available in 69% of study patients compared with 29% of literature cases at 24 hours (OR, 5.48 [95% CI, 2.62-12.06]), and 64% of study patients compared with 32% of cases at discharge (OR, 3.85 [95% CI, 1.87-8.19]). For study sites, median scores were 12 at baseline, 9 at 24 hours, and 5 at discharge. Median scores in case reports were 15 at baseline, 4 at 24 hours, and 3 at discharge. ORs for differences in outcomes between groups were 5.97 (95% CI, 2.28-15.59) at 24 hours and 3.68 (95% CI, 1.45-9.34) at discharge. CONCLUSIONS Study site patients had higher rates of National Institutes of Health Stroke Scale reporting and worse short-term outcomes compared with literature reports. Rigorous data collection is needed before treatment guidelines for pediatric mechanical thrombectomy can be developed.

Abstract
RATIONALE Acute ischemic stroke (AIS) is one of the most severe diseases that endanger human health. It is very common among middle-aged and elderly people, but it is rare in children. The treatment varies among children and adults, since the cause for AIS in children differs from that in adults. In adults with AIS, endovascular therapy has been recommended, but guidelines for endovascular therapy in children with AIS have not been established yet. In China, few relevant evidence is present so far in clinical research of mechanical thrombectomy in the treatment for children with AIS. PATIENT CONCERNS A 12-year-old boy without any special physical collision and trauma was admitted to emergency department of Changsha central hospital due to hemiplegia of left limbs for 3 hours. DIAGNOSES He was diagnosed with AIS after magnetic resonance imaging (MRI) examination and magnetic resonance angiography (MRA) examination. Cerebral infarction in the right parietal, temporal, insular, and frontal lobes was revealed by the MRI test. The MRA test detected occlusions in right internal carotid artery, A1 segment of right anterior cerebral artery, right middle cerebral artery, and distal branch. INTERVENTIONS Mechanic thrombectomy and antiplatelet aggregation therapy with clopidogrel helped the patient to recover, along with active rehabilitation training. OUTCOMES A significant improvement in muscle strength of his left limbs was proved. He walked by himself and had 2 of Modified Rankin Scale (MRS). At 1-year follow-up visit, he recovered well except feeling a bit pain of left lower limb when walking, with finally MRS of 1. CONCLUSIONS Mechanical thrombectomy can be performed safely for children with AIS, but needs a further research with large samples.

Mechanical thrombectomy in pediatric stroke: systematic review, individual patient data meta-analysis, and case series. J Neurosurg Pediatr 2019; 24:558-571. [PMID: 31398697 DOI: 10.3171/2019.5.peds19126] [Citation(s) in RCA: 30] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2019] [Accepted: 05/24/2019] [Indexed: 11/06/2022]
Abstract
OBJECTIVE The role of mechanical thrombectomy in pediatric acute ischemic stroke is uncertain, despite extensive evidence of benefit in adults. The existing literature consists of several recent small single-arm cohort studies, as well as multiple prior small case series and case reports. Published reports of pediatric cases have increased markedly since 2015, after the publication of the positive trials in adults. The recent AHA/ASA Scientific Statement on this issue was informed predominantly by pre-2015 case reports and identified several knowledge gaps, including how young a child may undergo thrombectomy. A repeat systematic review and meta-analysis is warranted to help guide therapeutic decisions and address gaps in knowledge. METHODS Using PRISMA-IPD guidelines, the authors performed a systematic review of the literature from 1999 to April 2019 and individual patient data meta-analysis, with 2 independent reviewers. An additional series of 3 cases in adolescent males from one of the authors' centers was also included. The primary outcomes were the rate of good long-term (mRS score 0-2 at final follow-up) and short-term (reduction in NIHSS score by ≥ 8 points or NIHSS score 0-1 at up to 24 hours post-thrombectomy) neurological outcomes following mechanical thrombectomy for acute ischemic stroke in patients < 18 years of age. The secondary outcome was the rate of successful angiographic recanalization (mTICI score 2b/3). RESULTS The authors' review yielded 113 cases of mechanical thrombectomy in 110 pediatric patients. Although complete follow-up data are not available for all patients, 87 of 96 (90.6%) had good long-term neurological outcomes (mRS score 0-2), 55 of 79 (69.6%) had good short-term neurological outcomes, and 86 of 98 (87.8%) had successful angiographic recanalization (mTICI score 2b/3). Death occurred in 2 patients and symptomatic intracranial hemorrhage in 1 patient. Sixteen published thrombectomy cases were identified in children < 5 years of age. CONCLUSIONS Mechanical thrombectomy may be considered for acute ischemic stroke due to large vessel occlusion (ICA terminus, M1, basilar artery) in patients aged 1-18 years (Level C evidence; Class IIb recommendation). The existing evidence base is likely affected by selection and publication bias. A prospective multinational registry is recommended as the next investigative step.

Abstract
The updated American Heart Association/American Stroke Association guidelines include recommendation for thrombectomy in certain adult stroke cases. The safety and efficacy of thrombectomy in children are unknown. An 8-year-old girl experienced acute stroke symptoms on two occasions while therapeutically anticoagulated on Novalung. Computed tomography scans showed proximal vessel thrombi, which were retrieved using a Trevo device without hemorrhagic complications. Postprocedural assessment found respective decreases in the National Institutes of Health Stroke Scale score from 10 to 4 and 12 to 7. The indications for treatment and early benefits observed in our case are consistent with other pediatric thrombectomy cases reported. However, publication bias and the heterogeneity of reported cases prevent drawing conclusions about the safety and efficacy of thrombectomy in children. Anticipating that updates to adult stroke guidelines would likely incite stroke providers to consider thrombectomy in children, our institution developed guidelines for thrombectomy before the index patient. Establishing institutional guidelines before considering thrombectomy in children may optimize patient safety.

Abstract
INTRODUCTION Current treatment guidelines for acute ischemic stroke do not recommend thrombolytic therapy in children and adolescents as data are still very scarce. CASE REPORT We report the case of a 15-year-old boy who suddenly developed severe left-sided weakness and speech difficulty while stooling. Upon arrival at our Emergency Department, the National Institute of Health Stroke Scale (NIHSS) score was 18. Urgent neurovascular ultrasound showed a distal occlusion of the right internal carotid artery and occlusion at the origin of the middle cerebral artery (MCA) and the anterior cerebral artery. He was treated 2 hours after symptom onset with intravenous recombinant tissue plasminogen activator without any complication. At the end of thrombolysis, a complete recanalization was shown by transcranial Doppler sonography, although a brain magnetic resonance imaging disclosed an acute right middle cerebral artery stroke. At discharge, the boy had mild weakness on his left leg and slight left facial palsy: the NIHSS score was 2. To our knowledge, this is the first intravenous thrombolytic treatment ever reported in an adolescent in Italy. CONCLUSIONS Despite the lack of evidence regarding the safety and the efficacy of recombinant tissue plasminogen activator in pediatric stroke, this treatment option should be considered, especially in adolescents presenting within 3 hours from symptom onset in centers with consolidated experience in adult thrombolysis.
