BACKGROUND Patients with acute ischemic stroke due to large vessel occlusion may present with concomitant carotid dissections that make the technical approach for their treatment challenging. The purpose of this study was to determine the safety and feasibility of flow diverter (FD) stents to treat carotid artery dissections in tandem lesions of acute ischemic stroke patients during mechanical thrombectomy. METHODS A retrospective review of all patients in which a carotid artery dissection was treated with an FD during endovascular treatment of acute ischemic stroke between 2018 and 2020 was conducted in 5 high‐volume Comprehensive Stroke Centers. Patient clinical and angiographical characteristics, postoperative outcome, and follow‐up were recorded. RESULTS A total of 12 patients (mean age: 54.18±14.74 years, median Alberta Stroke Program Early CT Score: 10 [interquartile range 9–10]) were included. Successful FD stenting with immediate patency of the dissected segments and successful intracranial recanalization modified thrombolysis in cerebral infarction score 2b‐3 after thrombectomy was achieved in all patients. A good outcome (modified Rankin scale 0–2 at 90 days) was achieved in 66% (8/12) of patients. In 25% (3/12) of patients, an additional self‐expanding carotid stent was used to anchor the FD proximally at the carotid bulb level. Complications included 1 symptomatic intracranial hemorrhage after procedure (24–48 hours) and 2 in‐stent stenoses at follow‐up. CONCLUSIONS In this small case series, the treatment of carotid artery dissection with FD stents was safe and technically feasible during mechanical thrombectomy of acute ischemic stroke patients with tandem lesions and resulted in a high rate of good clinical outcome. These results may provide the basis for designing larger prospective studies to assess the efficacy and safety of FD stents in selected patients with carotid tandem lesions.

OBJECTIVEThe 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.METHODSUsing 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).RESULTSThe 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.CONCLUSIONSMechanical 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.

Vessel Occlusion

Ischemic stroke due to large vessel occlusion (LVO) is a devastating condition. Most LVOs are embolic in nature. Arterial dissection is responsible for only a small proportion of LVOs, is specific in nature and poses some challenges in treatment. We describe 3 cases where patients with stroke caused by carotid artery dissection were treated with mechanical thrombectomy and extensive stenting with good outcome. We believe that mechanical thrombectomy and stenting is a treatment of choice in these cases.

Introduction: Data related to the treatment of patients with acute ischemic stroke caused by carotid artery dissection is scarce. Methods: We retrospectively reviewed our interventional stroke database Sep 2010 - Jan 2014 to investigate the clinical and radiological characteristics of patients presenting with tandem cervical and intracranial occlusions due to cervical carotid dissection. Results: Out of 504 consecutive patients treated with endovascular therapy for acute ischemic stroke during the study period, 12 (2.5%) patients were observed to have cervical carotid artery dissection as the underlying etiology. Mean age was 56±13 years, 75% were male, 50% received IV t-PA, mean NIHSS was 20±5, 75% had CT ASPECTS≥7, and mean time from last known normal to groin puncture was 6±3 hours. There were 4 MCA M1, 1 MCA M2 and 7 ICA-T occlusions. Extracranial carotid stent was used in 58% and angioplasty in 8% of cases. In 33% of the cases, the carotid dissection was not stented due to the fear of hemorrhagic transformation in cases of IV thrombolysis (presumably increased risk if dual antithrombotics used). IA tPA was used in 41% of cases, while Merci in 16%, Penumbra in 58%, and stentretrivers in 50%. Intracranial TICI 2b-3 reperfusion was achieved in 91% of patients, with PH2 hemorrhage in 8% and mRS at 90 days in 45% of cases. Conclusions: Carotid dissections with associated intracranial occlusions are often refractory to IV tPA and present with a high stroke severity. These lesions are amenable to endovascular therapy resulting in high rates of reperfusion with an acceptable safety profile.

Objective The purpose of this study is to demonstrate our experience in endovascular reconstruction of carotid dissections using the Wingspan Stent System™ (Boston Scientific, Natick, MA, USA), a device we use because of its high radial force and its navigation in extreme curves. Methods We treated 11 consecutive patients with acute ischemic stroke due to carotid dissection with the Wingspan stent, in the cervical carotid artery. Results Functional evaluation revealed that 10 of the 11 patients were independent at 3 months post surgery and that the 11 stents used were found to be patent at the 6-month follow-up digital subtraction angiography (DSA). Conclusions The Wingspan stent is an alternative to classic carotid stents and flow diverters for the treatment of cervical internal carotid artery (ICA) dissection associated with ectasias or large loops. The device remains patent over the long term and it is not associated with arterial wall complications.
