Background The coronavirus disease 2019 is associated with neurological manifestations including stroke. Objectives We present a case series of coronavirus disease 2019 patients from two institutions with acute cerebrovascular pathologies. In addition, we present a pooled analysis of published data on large vessel occlusion in the setting of coronavirus disease 2019 and a concise summary of the pathophysiology of acute cerebrovascular disease in the setting of coronavirus disease 2019. Methods A retrospective study across two institutions was conducted between 20 March 2020 and 20 May 2020, for patients developing acute cerebrovascular disease and diagnosed with coronavirus disease 2019. We performed a literature review using the PubMed search engine. Results The total sample size was 22 patients. The mean age was 59.5 years, and 12 patients were female. The cerebrovascular pathologies were 17 cases of acute ischemic stroke, 3 cases of aneurysm rupture, and 2 cases of sinus thrombosis. Of the stroke and sinus thrombosis patients, the mean National Institute of Health Stroke Scale was 13.8 ± 8.0, and 16 (84.2%) patients underwent a mechanical thrombectomy procedure. A favorable thrombolysis in cerebral infarction score was achieved in all patients. Of the 16 patients that underwent a mechanical thrombectomy, the mortality incidence was five (31.3%). Of all patients (22), three (13.6%) patients developed hemorrhagic conversion requiring decompressive surgery. Eleven (50%) patients had a poor functional status (modified Rankin Score 3–6) at discharge, and the total mortality incidence was eight (36.4%). Conclusions Despite timely intervention and favorable reperfusion, the mortality rate in coronavirus disease 2019 patients with large vessel occlusion was high in our series and in the pooled analysis. Notable features were younger age group, involvement of both the arterial and venous vasculature, multivessel involvement, and complicated procedures due to the clot consistency and burden.
BackgroundRobots in surgery aid in performing delicate, precise maneuvers that humans, with inherent physical abilities, may be limited to perform. The CorPath 200 system is FDA approved and is being implemented in the US for interventional cardiology procedures. CorPath GRX robotic-assisted platform is the next-generation successor of CorPath 200.ObjectiveTo discuss the feasibility and early experience with the use of the CorPath GRX robotic-assisted platform for neuroendovascular procedures, including transradial diagnostic cerebral angiograms and transradial carotid artery stenting.MethodsThe cases of 10 consecutive patients who underwent neuroendovascular robotic-assisted procedures between December 1, 2019 and December 30, 2019, are presented.ResultsSeven patients underwent elective diagnostic cerebral angiography, and three patients underwent carotid artery angioplasty and stenting using the CorPath GRX robotic-assisted platform. All procedures were performed successfully, and no complications were encountered. Conversion to manual control occurred in three diagnostic cases because of a bovine arch that was previously not known. The fluoroscopy time and the procedure time continued to improve with subsequent procedures as we streamlined the workflow.ConclusionThis series demonstrates the early use of this technology. It could potentially be used in the near future for acute stroke interventions in remote geographic locations and in places where a neurointerventionalist is not available.
BACKGROUND A dramatic improvement in obliteration rates of large, wide-necked aneurysms has been observed after the FDA approved the Pipeline Embolization Device (PED) in 2011. OBJECTIVE To assess the predictors of complications, morbidity, and unfavorable outcomes in a large cohort of patients with aneurysms treated with PED. METHODS A retrospective chart review of a prospectively maintained database for subjects treated with flow diversion from 2010 to 2019. RESULTS A total of 598 aneurysms were treated during a period extending from 2010 to 2019 (84.28% females, mean age 55.5 yr, average aneurysm size 8.49 mm). Morbidity occurred at a rate of 5.8% and mortality at a rate of 2.2%. Ischemic stroke occurred at a rate of 3%, delayed aneurysmal rupture (DAR) at 1.2%, and distal intraparenchymal hemorrhage (DIPH) at 1.5%. On multivariate analysis, the predictor of stroke was aneurysm size >15 mm. Predictors of DAR were previous subarachnoid hemorrhage (SAH), increasing aneurysm size, and posterior circulation aneurysm. Predictors of DIPH were using more than 1 PED and baseline P2Y12 value. Predictors of in-stent stenosis were the increasing year of treatment and balloon angioplasty, whereas increasing age and previous treatment were negatively associated with in-stent stenosis. Predictors of morbidity were posterior circulation aneurysms, increasing aneurysm size, and hypertension, and incidental aneurysm diagnosis was protective for morbidity. CONCLUSION Flow diversion is a safe and effective treatment option for aneurysms. A better understanding of predictive factors of complications, morbidity, and functional outcomes is of high importance for a more accurate risk assessment.
There is a dearth of evidence-based practice regarding the differential diagnosis, natural history, and management of post-craniotomy headache. The etiology of post-craniotomy headache is typically multifactorial, with patients' medical history, type of craniotomy, and perioperative management all playing a role. Post-craniotomy headaches are often undertreated, yet available evidence supports a multimodal approach for both prophylaxis and management. Many therapeutic techniques that aim to treat or prevent post-craniotomy headache require more robust validation than clinical evidence currently imparts. Pre- and intraoperative locoregional anesthesia should be the mainstay of prophylaxis; the role of opiates co-administered with analgesics, corticosteroids, and antiepileptic therapy in the acute perioperative phase is of paramount importance. Treatment of chronic PCH is less well-defined but should involve trials of analgesic, antineuropathic, and antiepileptic medications before enlisting experimental treatments. Comorbid psychiatric, musculoskeletal, or seizure disorders should be managed distinctly from post-craniotomy headaches. In patients failing all extant therapies, experimental approaches should be considered. These include subanesthetic ketamine infusion or surgical site injection with local anesthetics, corticosteroids, or botulinum toxin. Post-craniotomy headache is a complex phenomenon with many underutilized treatment options available, and many more under investigation. Nonetheless, further research is required to differentiate the efficacy of contemporary treatment strategies and to elucidate the applicability of novel therapies.
