RESUMEN
Stents are being widely used in the neuroendovascular field more often for assisted coiling of aneurysms and treatment of atherosclerotic stenosis. Stent detachment and embolization are one of the most feared complications associated with poor clinical outcomes. Many techniques have been detailed in the literature for extracting such dislodged stents. We describe a case of retrieval of an inadvertently detached balloon-mounted stent from the intracranial left vertebral artery. This occurred in a 58-year-old male patient with a history of diabetes mellitus whose stenting procedure was planned for severe intracranial atherosclerotic disease of bilateral vertebral arteries causing recurrent posterior circulation ischemic events. Stentectomy was performed successfully using a stent retriever. Intracranial vertebral artery stenting was eventually accomplished with excellent clinical outcomes.
RESUMEN
Pediatric intracranial aneurysms (PIA) are very rare and can be fatal if left untreated. There are many treatment strategies including microsurgical and endovascular techniques. We feel that endovascular treatment using trans-radial access (TRA) is safe and convenient for PIA compared to the trans-femoral access (TFA), which is commonly employed in this population. We present the case of the youngest patient in the world whose ruptured aneurysm was treated with endovascular coiling via the TRA. The seven-year-old patient was brought to the ER with a severe headache. He had several episodes of vomiting and an episode of seizure as well. Computerized tomography (CT) of the brain showed subarachnoid hemorrhage. A magnetic resonance angiogram (MRA) showed an aneurysm at the bifurcation of the right internal carotid artery (ICA). An intermediate catheter/microcatheter system was used to navigate up into the ICA and then into the aneurysm. Two coils were deployed with good packing. The patient had a good clinical recovery and is currently doing good without any neurological deficits. With the availability of newer devices, we believe the TRA will be widely used in the coming years. We need to have larger randomized controlled trials to really understand the advantages of TRA in this patient population.
RESUMEN
BACKGROUND: Failed mechanical thrombectomy due to a refractory emergent large vessel occlusion (RELVO) in patients presenting with an acute stroke poses a major challenge to the outcomes. OBJECTIVE: We demonstrate the use of coronary stents in the intracranial circulation as rescue stenting for an already expensive mechanical thrombectomy procedure in a mid-low socioeconomic setting. METHODS: A retrospective, multicenter study was conducted between December 2015 and January 2021. The studied cohort were patients who required the use of a rescue stenting using a coronary stent for emergent large vessel occlusion to avoid failed recanalization. Failed recanalization was defined as failed vessel recanalization after at least two passes. Patient demographic data, procedure specifics, type of stent used, and procedural outcomes were collected. RESULTS: A total of 26 patients with acute ischemic stroke were included from eight different centers across India. Out of 26 patients, 19 (73.0%) were male and seven were female (26.9%). The mean age was 53.6 years, the youngest patient was 23 years old and the eldest was 68 years old. Seven patients (26.9%) had posterior circulation stroke due to occlusion of the vertebral or basilar artery and 19 patients (73.0%) had anterior circulation stroke median NIHSS at presentation was 16 (range 10 to 28) in anterior circulation stroke and 24 (range 16 to 30) in posterior circulation stroke. Intravenous thrombolysis with tissue plasminogen activator (IV tPA) was given in three patients (11.5%). The hospital course of two patients was complicated by symptomatic intracranial hemorrhage (sICH), which was fatal. Favorable revascularization outcome and favorable functional outcome was achieved in 22 patients (84.6%), three patients passed away (11.5%), and one patient was lost to follow up. CONCLUSIONS: Overall, our study finds that rescue stenting using coronary stents can potentially improve outcomes in refractory large vessel occlusions while minimizing costs in low-mid economic settings.
