Objectives. The carotid-cavernous fi stula (CCF) represents an abnormal communication developed between the internal and/or the external carotid artery (ICA, ECA) or their branches and the cavernous sinus (CS). We report this case in order to highlight the course and an alternative to treatment of a CCF. Material and methods. A 47-year old male patient with medical history of subarachnoid hemorrhage and cranio-facial comminuted fractures due to a motorcycle accident-induced craniofacial traumatism (4 months prior to admission) was referred to our clinic for further investigation regarding a potential CCF. Results. The cerebral digital substraction angiography showed a direct CCF type A. The Neurology and Interventional Radiology team opted for endovascular stent-grafting of the right ICA. Conclusions. This case is presented in order to highlight that angioplasty with stent-graft is a safe and effectiveprocedure in selected cases of CCF.

Delta-aminolevulinic acid dehydratase porphyria (ADP) is a rare cause of acute polyneuropathy. It should be part of the differential diagnosis in every patient presenting with polyneuropathy and elevated liver enzymes. Genetic, acquired and environmental factors can play a role in the clinical manifestations and there are several steps in reaching the diagnosis. We present the case of a male patient with at least two possible causes for his symptoms, the diagnostic process and the outcome.

Background COVID-19 infection has been known to predispose patients to both arterial and venous thromboembolic events such as deep venous thrombosis, pulmonary embolism, myocardial infarction, and stroke. A few reports from the literature suggest that Cerebral Venous Sinus Thrombosis (CVSTs) may be a direct complication of COVID-19. Objective To review the clinical and radiological presentation of COVID-19 positive patients diagnosed with CVST. Methods This was a multicenter, cross-sectional, retrospective study of patients diagnosed with CVST and COVID-19 reviewed from March 1, 2020 to November 8, 2020. We evaluated their clinical presentations, risk factors, clinical management, and outcome. We reviewed all published cases of CVST in patients with COVID-19 infection from January 1, 2020 to November 13, 2020. Results There were 8 patients diagnosed with CVST and COVID-19 during the study period at 7 out of 31 participating centers. Patients in our case series were mostly female (7/8, 87.5%). Most patients presented with non-specific symptoms such as headache (50%), fever (50%), and gastrointestinal symptoms (75%). Several patients presented with focal neurologic deficits (2/8, 25%) or decreased consciousness (2/8, 25%). D-dimer and inflammatory biomarkers were significantly elevated relative to reference ranges in patients with available laboratory data. The superior sagittal and transverse sinuses were the most common sites for acute CVST formation (6/8, 75%). Median time to onset of focal neurologic deficit from initial COVID-19 diagnosis was 3 days (interquartile range 0.75–3 days). Median time from onset of COVID-19 symptoms to CVST radiologic diagnosis was 11 days (interquartile range 6–16.75 days). Mortality was low in this cohort (1/8 or 12.5%). Conclusions Clinicians should consider the risk of acute CVST in patients positive for COVID-19, especially if neurological symptoms develop.

CLOSE and Gore-REDUCE trials have recently changed the way we approach patients with stroke and patent foramen ovale. We present the case of a young patient with an Embolic Stroke of Undetermined Source (ESUS) and an atrial septal defect causing a large right-to-left shunt, with an ample discussion on evidence-based decision making.
