ABSTRACT
Background and aims: Optimal management of carotid artery freefloating thrombus (CAFFT) and CAFFT-related strokes remains unclear. We sought to examine the clinical characteristics, treatment strategies and patient outcomes for CAFFT-related ischaemic strokes. Methods: We conducted a single-centre retrospective observational study by extracting data from electronic patient records. We included consecutive patients admitted between 2016-2021 with ischaemic stroke and CAFFT on initial CT/MR angiogram. Results: We included 59 patients (mean age 63, 66% male). Vascular risk factors included hypertension (42%), diabetes (19%), dyslipidaemia (27%), previous stroke (10%), smoking history (56%) and alcohol excess (14%). 6 patients (10%) were COVID-19 positive. Median modified Rankin score was 0 and mean NIHSS was 11. On admission, 42% were taking antiplatelet agents, 10% were on anticoagulant, 34% had CRP >10mg/L, and 14% had eGFR <50 ml/min/1.73m2. On arrival, 27% received IV thrombolysis and 19% underwent mechanical thrombectomy. Acute antithrombotic strategies included IV heparin (49%), low molecular weight heparin (47%), oral anticoagulation (15%), and antiplatelet agents (63%). 24 patients (41%) were referred to vascular surgery, of whom 9 (38%, 15% of total) received emergency carotid endarterectomy. Neurological deterioration (<7 days) occurred in 14%. In-hospital mortality was 8% overall, but 67% for COVID-positive patients. At 6 months, recurrent stroke occurred in 12% and mortality was 3%. Conclusions: CAFFT-related ischaemic stroke is associated with significant mortality and neurological morbidity. The use of different acute antithrombotic strategies and emergency carotid endarterectomy varied significantly between patients. These major treatment options should be subjects of future clinical trials.
ABSTRACT
Background: Paediatric Cov-2 infections have been less severe than in adults, however some have developed a newly defined syndrome, Paediatric Inflammatory Multisystem Syndrome associated with CoV-2 (PIMS -TS). Its presentation is variable and can cause multi-system involvement. It belongs to the common spectrum of pathogen-triggered hyperinflammatory states, including atypical Kawasaki disease. Case summary: 17 year old male of Ghanaian origin, with no significant past medical history, presented with a one-week history of general malaise, fevers and sore throat. He developed severe chest pain and cardiogenic shock, with a CRP of 200, raised troponin and global hypokinesia on echocardiogram with an ejection fraction of 20%. He was positive for SARS-CoV-2 antibodies (though PCR-antigen negative at admission) and fit the criteria for myocarditis secondary to PIMS-TS. He was treated for sepsis, commenced on IV methylprednisolone and needed intubation, sedation and cardiothoracic ICU level care. On weaning sedation after 3 days, he was found to have left middle cerebral artery syndrome with NIHSS 16. CT head and CT angiogram showed a left MCA ischaemic stroke, and a thrombus in the Sylvian MCA branch. This was treated with antiplatelets. His disease markers and motor deficits improved significantly, however he has cognitive impairment and low mood. Conclusion: PIMS-TS related LVO anterior circulation infarct is rare. It necessitates urgent recognition and multi-specialty involvement as currently management is not standardised. Axial DWI (A), ADC (B) MRI demonstrate large left MCA territory infarct. Axial MRA (C) shows occlusion of the left M2 branches, signal drop-out on SWI (D).
ABSTRACT
Aims: The STT pathway was borne out of the National Cancer Strategy 2015 and faster diagnosis standard to rule in, or out, cancer within 28 days of referral. We aimed to review local target standard of practice, including comparison of STT vs Traditional pathways towards reaching the national standards. Methods: The Somerset Database for all target referrals to the department was accessed. We chose October 2019 as a period unaffected by COVID-19. Time to investigation, results and treatment were reviewed. SPSS v.16 was used to perform an unpaired T-test of Traditional vs. STT time to diagnosis. Results: 212 patients were referred for target investigations. 53 declined, DNA-ed or were unfit. 159 proceeded to investigations of which 7 cancers were diagnosed: 4 colorectal, 1 gastric and 2 lung. Time to diagnosis averaged 45.8 days and only 47/159 (29.6%) had their definitive diagnosis in 28 days. 52 patients were streamed to STT and 107 traditional pathways. STT patients were diagnosed at 36.3 days (95% CI 28.1- 44.6) and traditional patients 50.5 days (95% CI 45.4-55.7) (P=0.005). Cancer treatment was received median day 59 (range 27-189) and 4/7 received this within 62 days. Conclusion: Target investigations have low pick up rates of cancers with ever increasing referrals. Our centre did not meet aspirational national targets of time to treatment or diagnosis, although STT patients were diagnosed significantly faster. With COVID-19, rationalisation of patient contact with maintained diagnosis rates must be strategised. Stricter FIT testing with risk stratification and STT expansion is one strategy.
ABSTRACT
There are very limited published data on the neurologic complications associated with coronavirus disease 2019 (COVID-19) in the pediatric population. Here we present the first 2 pediatric cases of presumed COVID-19 related cytotoxic lesions of the corpus callosum. Similar to reports in adults, these cases suggest that the COVID-19 infection in children may rarely mediate a hyperinflammatory response that can cause CNS pathology. As the pandemic continues further, the presentation of cytotoxic lesions of the corpus callosum should prompt radiologists to consider COVID-19, among other known causes.
