ABSTRACT

BACKGROUND: To analyse the clinical characteristics of COVID-19 with acute ischaemic stroke (AIS) and identify factors predicting functional outcome. METHODS: Multicentre retrospective cohort study of COVID-19 patients with AIS who presented to 30 stroke centres in the USA and Canada between 14 March and 30 August 2020. The primary endpoint was poor functional outcome, defined as a modified Rankin Scale (mRS) of 5 or 6 at discharge. Secondary endpoints include favourable outcome (mRS ≤2) and mortality at discharge, ordinal mRS (shift analysis), symptomatic intracranial haemorrhage (sICH) and occurrence of in-hospital complications. RESULTS: A total of 216 COVID-19 patients with AIS were included. 68.1% (147/216) were older than 60 years, while 31.9% (69/216) were younger. Median [IQR] National Institutes of Health Stroke Scale (NIHSS) at presentation was 12.5 (15.8), and 44.2% (87/197) presented with large vessel occlusion (LVO). Approximately 51.3% (98/191) of the patients had poor outcomes with an observed mortality rate of 39.1% (81/207). Age >60 years (aOR: 5.11, 95% CI 2.08 to 12.56, p<0.001), diabetes mellitus (aOR: 2.66, 95% CI 1.16 to 6.09, p=0.021), higher NIHSS at admission (aOR: 1.08, 95% CI 1.02 to 1.14, p=0.006), LVO (aOR: 2.45, 95% CI 1.04 to 5.78, p=0.042), and higher NLR level (aOR: 1.06, 95% CI 1.01 to 1.11, p=0.028) were significantly associated with poor functional outcome. CONCLUSION: There is relationship between COVID-19-associated AIS and severe disability or death. We identified several factors which predict worse outcomes, and these outcomes were more frequent compared to global averages. We found that elevated neutrophil-to-lymphocyte ratio, rather than D-Dimer, predicted both morbidity and mortality.

ABSTRACT

BACKGROUND AND PURPOSE: Previous studies suggest that mechanisms and outcomes in patients with COVID-19-associated stroke differ from those in patients with non-COVID-19-associated strokes, but there is limited comparative evidence focusing on these populations. The aim of this study, therefore, was to determine if a significant association exists between COVID-19 status with revascularization and functional outcomes following thrombectomy for large vessel occlusion (LVO), after adjustment for potential confounding factors. METHODS: A cross-sectional, international multicenter retrospective study was conducted in consecutively admitted COVID-19 patients with concomitant acute LVO, compared to a control group without COVID-19. Data collected included age, gender, comorbidities, clinical characteristics, details of the involved vessels, procedural technique, and various outcomes. A multivariable-adjusted analysis was conducted. RESULTS: In this cohort of 697 patients with acute LVO, 302 had COVID-19 while 395 patients did not. There was a significant difference (p < 0.001) in the mean age (in years) and gender of patients, with younger patients and more males in the COVID-19 group. In terms of favorable revascularization (modified Thrombolysis in Cerebral Infarction [mTICI] grade 3), COVID-19 was associated with lower odds of complete revascularization (odds ratio 0.33, 95% confidence interval [CI] 0.23-0.48; p < 0.001), which persisted on multivariable modeling with adjustment for other predictors (adjusted odds ratio 0.30, 95% CI 0.12-0.77; p = 0.012). Moreover, endovascular complications, in-hospital mortality, and length of hospital stay were significantly higher among COVID-19 patients (p < 0.001). CONCLUSION: COVID-19 was an independent predictor of incomplete revascularization and poor functional outcome in patients with stroke due to LVO. Furthermore, COVID-19 patients with LVO were more often younger and had higher morbidity/mortality rates.

ABSTRACT

The 2020 update of the Canadian Stroke Best Practice Recommendations (CSBPR) for the Secondary Prevention of Stroke includes current evidence-based recommendations and expert opinions intended for use by clinicians across a broad range of settings. They provide guidance for the prevention of ischemic stroke recurrence through the identification and management of modifiable vascular risk factors. Recommendations address triage, diagnostic testing, lifestyle behaviors, vaping, hypertension, hyperlipidemia, diabetes, atrial fibrillation, other cardiac conditions, antiplatelet and anticoagulant therapies, and carotid and vertebral artery disease. This update of the previous 2017 guideline contains several new or revised recommendations. Recommendations regarding triage and initial assessment of acute transient ischemic attack (TIA) and minor stroke have been simplified, and selected aspects of the etiological stroke workup are revised. Updated treatment recommendations based on new evidence have been made for dual antiplatelet therapy for TIA and minor stroke; anticoagulant therapy for atrial fibrillation; embolic strokes of undetermined source; low-density lipoprotein lowering; hypertriglyceridemia; diabetes treatment; and patent foramen ovale management. A new section has been added to provide practical guidance regarding temporary interruption of antithrombotic therapy for surgical procedures. Cancer-associated ischemic stroke is addressed. A section on virtual care delivery of secondary stroke prevention services in included to highlight a shifting paradigm of care delivery made more urgent by the global pandemic. In addition, where appropriate, sex differences as they pertain to treatments have been addressed. The CSBPR include supporting materials such as implementation resources to facilitate the adoption of evidence into practice and performance measures to enable monitoring of uptake and effectiveness of recommendations.

ABSTRACT

Carotid-cavernous fistulas (CCFs) are abnormal vascular shunts between the carotid artery and the cavernous sinus. A 37-year-old male presented with a traumatic CCF and basal skull fracture extending through the medial wall of the cavernous sinus and sphenoid sinus. The CCF was treated with endovascular coiling. Three months after this procedure, he was found to have coil migration through the traumatic sphenoid defect into the pharynx. He underwent urgent endonasal endoscopic surgery to disconnect and remove the extruded coil. Post-operative coil migration is a rare but serious complication following endovascular treatment of traumatic CCF.

ABSTRACT

PURPOSE: To determine the efficacy and safety of cryoablation in patients with desmoid tumors (DTs) retrospectively over a 10-year period at a single institution. MATERIALS AND METHODS: Between February 25, 2010, and February 25, 2020, 25 patients (age, 12-80 years) with 26 lesions (mean preprocedural tumor volume was 237 cm3) were treated over 44 cryoablation procedures. Eleven patients were treated with first-line therapy. Fourteen patients had previous medical therapy, radiotherapy, and/or surgery. Subsequent clinical follow-up, imaging outcomes, and safety were analyzed for technical success, change in total lesion volume (TLV) and viable tumor volume (VTV), modified response evaluation criteria in solid tumors (mRECIST), progression-free survival (PFS) for tumor progression and symptom recurrence, symptom improvement, and procedure-related complications. Symptomatic improvement was defined as documentation of relief of pain (partial or complete) and/or functional impairment. RESULTS: All procedures were technically successful. At 7-12 months, median changes in TLV and VTV were -6.7% (P = .809) and -43.7% (P = .01), respectively. At 10-12 months, the mRECIST responses were complete response, 0%; partial response, 61.5% (8/13); stable disease, 30.8% (4/13); and progressive disease, 7.7% (1/13). The median PFS for tumor progression and symptom recurrence were not reached, with a median follow-up of 15.3 and 21.0 months, respectively. Symptomatic relief (partial or complete) was achieved in 96.9% (32/33) of patients. One major complication was noted (2.4%). CONCLUSIONS: In this retrospectively identified cohort, cryoablation was effective and safe for the local control of extra-abdominal DTs in short-term follow-up.

ABSTRACT

OBJECTIVES: Patients with essential tremor treated with thalamic deep brain stimulation may experience increased tremor with the progression of their disease. Initially, this can be counteracted with increased stimulation. Eventually, this may cause unwanted side-effects as the circumferential stimulation from a standard ring contact spreads into adjacent regions. Directional leads may offer a solution to this clinical problem. We aimed to compare the ability of a standard and a directional system to reduce tremor without side-effects and to improve the quality of life for patients with advanced essential tremor. MATERIALS AND METHODS: Six advanced essential tremor patients with bilateral thalamic deep brain stimulation had their standard system replaced with a directional system. Tremor rating scale scores were prospectively evaluated before and after the replacement surgery. Secondary analyses of quality of life related to tremor, voice, and general health were assessed. RESULTS: There was a significantly greater reduction in tremor without side-effects (p = 0.017) when using the directional system. There were improvements in tremor (p = 0.031) and voice (p = 0.037) related quality of life but not in general health for patients using optimized stimulation settings with the directional system compared to the standard system. CONCLUSIONS: In this cohort of advanced essential tremor patients who no longer had ideal tremor reduction with a standard system, replacing their deep brain stimulation with a directional system significantly improved their tremor and quality of life. Up-front implantation of directional deep brain stimulation leads may provide better tremor control in those patients who progress at a later time point.

ABSTRACT

BACKGROUND AND PURPOSE: We aim to describe the burden, characteristics, and cognitive associations of cerebral small vessel disease in a Canadian sample living with multimorbidity in precarious housing. METHODS: Participants received T1, T2-fluid-attenuated inversion recovery, and susceptibility-weighted imaging 3T magnetic resonance imaging sequences and comprehensive clinical, laboratory, and cognitive assessments. Cerebral small vessel disease burden was characterized using a modified Small Vessel Disease (mSVD) score. One point each was given for moderate-severe white matter hyperintensities, ≥1 cerebral microbleeds, and ≥1 lacune. Multivariable regression explored associations between mSVD score, risk factors, and cognitive performance. RESULTS: Median age of the 228 participants (77% male) was 44.7 years (range, 23.3-63.2). In n=188 participants with consistent good quality magnetic resonance imaging sequences, mSVD scores were 0 (n=127, 68%), 1 (n=50, 27%), and 2 (n=11, 6%). Overall, one-third had an mSVD ≥1 n=61 (32%); this proportion was unchanged when adding participants with missing sequences n=72/228 (32%). The most prevalent feature was white matter hyperintensities 53/218 (24%) then cerebral microbleed 16/191 (8%) and lacunes 16/228 (7%). Older age (odds ratio, 1.10 [95% CI, 1.05-1.15], P<0.001), higher diastolic blood pressure (odds ratio, 1.05 [95% CI, 1.01-1.09], P=0.008), and a history of injection drug use (odds ratio, 3.13 [95% CI, 1.07-9.16], P=0.037) had significant independent associations with a mSVD score of ≥1 in multivariable analysis. mSVD ≥1 was associated with lower performance on tests of verbal memory, sustained attention, and decision-making, contributing 4% to 5% of the variance in each cognitive domain. CONCLUSIONS: The 32% prevalence of cerebral small vessel disease in this young, socially marginalized cohort was higher than expected for age and was associated with poorer cognitive performance.

ABSTRACT

Post-dural puncture headache is an uncommon entity in young children and adolescents. Percutaneous epidural blood patching has been classically used to manage refractory post-dural puncture headaches. Injectable fibrin sealant has been shown in a few adult cases to relieve symptoms where blood patching has either failed or was not appropriate. We report a 10-year-old boy who experienced rapid relief of post-dural puncture headache symptoms following percutaneous lumbar epidural fibrin sealant injection under computed tomography guidance. Percutaneous epidural fibrin sealant injection may be an acceptable treatment for post-dural puncture headaches refractory to epidural blood patching, or when an epidural blood patch is otherwise contraindicated. The pediatric interventional radiologist should be aware of this off-label use of fibrin sealant.

ABSTRACT

We report a case of an 8-year-old boy who presented to our emergency department with progressive onset of dysphagia and odynophagia after eating barbecued steak that evening. Radiographs revealed a metal bristle from a barbecue brush at the level of the proximal esophagus. The otolaryngologist attempted to retrieve this bristle using flexible esophagoscopy, but unfortunately it pushed the bristle extra-esophageal. In order to avoid major open surgery with associated morbidity, a novel percutaneous image-guided minimally invasive percutaneous approach was used to successfully retrieve the bristle.

ABSTRACT

OBJECTIVE: Pediatric interventional radiology (PIR) is a dynamic and growing subspecialty. We will detail our need to evolve like the emerging therapies and innovative imaging options that we provide to children. CONCLUSION: New interventional radiology training pathways, maintaining competency with small volumes of complex procedures, limited availability of pediatric-specific equipment, questions about the safety of sedation in the developing brain, and the dearth of PIR opportunities outside of North America provide challenges and opportunities for the vibrant community of PIR practitioners.

ABSTRACT

PURPOSE: Prior literature has shown that routine postoperative computed tomography (CT) scans for mandibular fractures have no effect on outcomes and complications; however, past surveys have reported that most clinicians continue to order routine scans. We aimed to determine the current use of routine postoperative CT scans, evaluate what factors contribute to this practice, and identify differences in outcomes and complications among patients with either routine, indicated, or no postoperative CT scans. PATIENTS AND METHODS: We conducted a retrospective review of consecutive patients treated for a mandibular fracture at Vancouver General Hospital from January 1, 2007, to March 1, 2012. RESULTS: We included 167 patients in the study for analysis. No significant differences in outcomes or complications were found between patients who had an indicated postoperative CT scan (27%) and patients with no scans (64%). Only the treating surgeon had a statistically significant effect on whether a patient received a postoperative CT scan (P < .001), and those patients who had an indicated postoperative CT scan (9%) were more likely to have a decreased level of temporomandibular joint function (P = .002) and increased incidence of complications and secondary operations (P < .001 and P < .001, respectively). CONCLUSIONS: Routine postoperative CT scans were found to have no significant effect on outcomes and complications, and a clinician's individual practice was the most significant factor for whether a patient received a routine postoperative CT scan. Future work should aim at providing well-defined indications for postoperative imaging.

ABSTRACT

Intrathecal baclofen has long been known to be an efficacious treatment of spasticity in children with cerebral palsy. Test bolus administration is often necessary to ensure patients will benefit from this treatment. The introduction of a intrathecal catheter for test bolus administration can prove challenging in a subset of this population, particularly those who have received surgery with postoperative spinal fusion masses. We outline a novel technique of inserting a spinal catheter for test bolus administration in a patient with a postoperative fusion mass whereby a fenestration is created through the lamina using an osteotomy needle.

ABSTRACT

PURPOSE: Herein, the authors aim to describe their findings of novel architectural types of lymphatic malformations (LM) and explain the relationship between these architectures and OK-432 treatment outcomes. METHODS: A retrospective review was conducted of all patients diagnosed with a LM treated with OK-432 at the Vascular Anomalies Clinic at BC Children's Hospital from December 2002 to January 2012. RESULTS: Twenty-seven patients were included in the study. Sixty percent of lesions were present by 2 years of age with the majority located in the head and neck (59%). The average number of sclerotherapy procedures was 1.4 per patient. Treatment under fluoroscopic guidance revealed 3 new LM architectures: open-cell microcystic, closed-cell microcystic, and lymphatic channel. Response to treatment was complete or good for 14/19 macrocystic and for 1/2 mixed lesions. Open-cell microcystic LMs gave a complete or good response for 3/3, which was attributed to OK-432 freely communicating between cysts. Closed-cell microcystic LM had localized cysts that did not allow OK-432 to freely communicate and were associated with partial responses, 2/2. The lymphatic channel had a partial response. There were 2 minor complications and 1 instance of recurrence. CONCLUSIONS: The identification of 3 new LM architectures expands the current accepted classification to include: open-cell microcystic, closed-cell microcystic, and lymphatic channels. The majority of complete responses to OK-432 were found with macrocystic lesions. Open-cell microcystic lesions respond better to OK-432 than closed-cell microcystic lesions, and lymphatic channels may respond to OK-432. These key architecture-response relationships have direct clinical implications for treatment with OK-432 sclerotherapy.

ABSTRACT

PURPOSE: To determine the causes of lacrimal gland inflammation based on histopathology and systemic evaluation. METHODS: This is a retrospective case series study. From the University of British Columbia Orbit Clinic between January 1976 and December 2008, we reviewed the medical records of 60 patients who presented with inflammatory features of the lacrimal gland (i.e., erythema, edema, or tenderness) in which the diagnoses were not possible clinically and on imaging alone. As was our routine practice, all these patients underwent lacrimal gland biopsy before starting any treatment. RESULTS: The histopathologic findings of the 60 patients showed that 37 (61.7%) had identifiable types of lacrimal inflammation including 10 with Sjogren's syndrome, seven with sarcoidal reaction, six with feature of granulomatosis with polyangiitis (formerly known as Wegener's granulomatosis), five with lymphoma, two with sclerosing inflammation, two with IgG4-related dacryoadenitis, and one patient each with infectious dacryoadenitis, myoepithelial carcinoma, xanthogranuloma, eosinophilic angiocentric fibrosis, and eosinophilic allergic granulomatous nodule. The histopathologic findings of the remaining 23 (38.3%) patients showed nonspecific inflammation of the lacrimal gland. 23 patients (38.3%) had associated systemic diseases. 48 patients (80%) were treated successfully and 10 (16.7%) had recurrence of inflammation. CONCLUSIONS: We recommend that in patients presenting with lacrimal gland inflammation (i.e., erythema, edema, tenderness) in which the specific diagnosis cannot be made clinically and on imaging, biopsy is warranted for accurate diagnosis and appropriate treatment. We found that the majority of these patients (61.7%) had specific histopathology, and 38% had systemic diseases.

ABSTRACT

Prompt and accurate diagnosis is the foundation of acute ischaemic stroke care. Multiple positive endovascular thrombectomy trials in ischaemic stroke patients with large vessel occlusions have further emphasised this but also added complexity to treatment decisions. CT angiography is now routine for patients who present with an acute stroke syndrome around the world. Members of the neurology and stroke teams (rather than radiologists) are often the first doctors to lay eyes on the CT images and are best equipped to integrate the clinical picture with the imaging findings. A sound understanding of acute stroke imaging is therefore essential for clinicians who work with acute stroke patients. This review describes some pearls we have gleaned from our own experience in acute stroke imaging as well as some potential follies to be avoided.
