Abstract Background New Oral Anticoagulants (NOACs) such as Rivaroxaban are introduced as alternatives to conventional vitamin-K antagonists in the long-term treatment of thrombotic events due to their lower bleeding risk. There is a lack of evidence on the effectiveness and safety of Rivaroxaban in Cerebral venous thrombosis (CVT). This study aims to assess the effectiveness and bleeding risk of Rivaroxaban in comparison with Warfarin for the treatment of CVT. Materials and methods 36 patients with diagnosis of CVT were included. Clinical and background information was assessed on admission and patients were followed for at least 12 months. Measured outcomes were modified Rankin Scale (mRS), evidence of recanalization on contrast-enhanced Brain MR venography (MRV) and major or minor bleeding. Patients were divided into two groups according to the type of oral anticoagulant (Rivaroxaban vs Warfarin). Groups were compared in terms of final outcomes and side effects. Result Overall, 13 (36.11%) patients received Warfarin and 23 (63.89%) received Rivaroxaban. Optimal mRS score (0–1) was attained in 9 of 10 (90%) of patients treated with Rivaroxaban and 19 of 22 (86.36%) of patients received Warfarin. MRV showed complete or partial recanalization in 12 of 14 (85.71%) patients treated with Rivaroxaban and all patients in the Warfarin group. There was no significant difference between the two groups in terms of major and minor hemorrhage. Conclusion Rivaroxaban holds promise for the treatment of CVT.

Background: Cerebral venous thrombosis (CVT) is an uncommon cause of stroke that mainly affects young adults and children. Initial treatment with heparin followed by wafarin is the mainstay of treatment. Only insufficient experience is available for direct oral anticoagulants (DOACs). Aims: The study aims to demonstrate the efficacy and safety of DOACs such as (Rivaroxaban and Dabigatran) in patients with objectively confirmed CVT. Methods: Data of 46 cases of CVT collected using a standardized case report form. Inclusion criteria were patients diagnosed with CVT, confirmed by CT or MRI imaging. Results: The total number of patients was 46 (9 males and 37 females). The mean age of the patients was 35.2± 5 years. The most common clinical manifestations among our patients were headache followed by seizure. 52% of cases were unprovoked, while 48% were provoked by pregnancy and oral contraceptive pills. Superior sagittal sinus (55%) and transverse sinus (44.9%) were the most common sites. Involvement of more than three venous sinuses was 34.8%. Thrombophilic abnormality was detected in 21.7% of patients. Initiation of anticoagulation (AC) was mostly low molecular weight heparin (LMWH) (80%), followed by unfractionated heparin (UFH) (17.7%) and fondaparinex (2%). Maintenance AC with Rivaroxaban after heparin (LMWH/UFH) was in 63% of our patients, the rest were switched from Warfarin to Rivaroxaban (34.8%), and one was treated by Dabigatran (2%). CVT recurrence was observed in one patient. Major bleeding (according to ISTH criteria) was not reported in our case series. Conclusions: DOACs demonstrated good safety and efficacy profile and can potentially replace warfarin in CVT patients. Disclosures No relevant conflicts of interest to declare.

Coronavirus disease-2019 is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 virus). Coronavirus disease-2019 (COVID-19) was declared a pandemic in March 2020 and has changed our lives in many ways. This infection induces a hypercoagulable state leading to arterial and venous thrombosis, but the exact pathophysiology of thrombosis is unknown. However, various theories have been postulated including excessive cytokine release, endothelial activation, and disseminated intravascular coagulation (DIC). We present a patient diagnosed with cerebral venous sinus thrombosis (CVST) with COVID-19 infection. A 66-year-old man presented to a hospital for evaluation of persistent headaches. He tested positive for COVID-19, and MRI of the brain and CT venogram revealed CVST. He was started on heparin drip in the hospital and transitioned to oral anticoagulants at the time of discharge. His headaches improved with treatment. Even though headache is the most frequent and initial symptom of cerebral venous thrombosis, it is rarely the only symptom. A high index of suspicion is therefore required to diagnose CVST especially if the patient presents with a simple complaint like a headache. Common complaints can delay the diagnosis leading to disease progression. Considering the high mortality rates in patients diagnosed with CVST, we suggest the importance of knowing the association between COVID-19 infection and CVST, especially in susceptible patients.

Isotope Scanning

SummaryIn 2 groups of non surgical patients with venous thrombosis (V. T.) the fibrinogen turnover rate was determined in addition to scanning of the legs.In the first group of 13 patients with clinical signs of V. T. the Tx/2 of 131I-fibrinogen was shorter than in a normal group. In the second group of 10 patients with V. T., diagnosed only by local scanning of the legs using 125I-fibrinogen, the T72 was also shortened.Because of the longer half life time of the 125I-label, observations can be carried out during a period of 20 days, so that 125I-fibrinogen is preferable to 131I-fibrinogen. Of 33 elderly patients treated for congestive heart failure a positive leg scan was observed in 15. Treatment with intravenously injected heparin immediately interferes with further accumulation of radioactivity and corrects the shortened TVa to normal values, in contrast to treatment with oral anticoagulants.

SummaryIt would be important to estimate in advance the risk of recurrent thrombosis. Deficiencies of antithrombin, protein C or protein S, or resistance to activated protein C are associated with a biochemically detectable prethrombotic state. It is thus far unknown whether in patients with a history of thromboembolism but without a defined clotting abnormality a heightened coagulation activation is detectable.We investigated the value of prothrombin fragment Fl+2 (FI+2) as a predictor of recurrent venous thromboembolism. Furthermore, we compared the Fl+2 levels of thrombosis patients without a defined clotting defect to those of Factor V Leiden patients with a history of venous thrombosis and to those of healthy controls. 180 patients without a defined clotting abnormality and 73 patients with Factor V Leiden were prospectively followed after discontinuation of oral anticoagulants for venous thrombosis and Fl+2 was measured at regular intervals.Recurrent venous thromboembolism occurred in 23 (9%) of the 253 patients. Before or at several time points after oral anticoagulants, no significant difference in Fl+2 levels was found in patients with and without recurrent thrombosis. Fl+2 levels at 3 weeks and prior to recurrence were not significantly different in both patient groups. Over a one-year observation period, Fl+2 levels of both patients with and without Factor V Leiden were higher than those of the controls. No difference in Fl+2 was seen between patients with and without Factor V Leiden.We conclude that monitoring of Fl+2 is not suitable for identification of individuals at risk of recurrent venous thrombosis. Permanent hemostatic system activation is detectable both in patients with a defined abnormality of the clotting system and in patients in whom a particular defect has not (yet) been identified.
