D-Dimer versus International Normalized Ratio of Prothrombin Time in Ischemic Stroke Patients Treated with Sufficient Warfarin
In patients receiving chronic warfarin therapy, the international normalized ratio of prothrombin time (PT-INR) reportedly correlates with the incidence, size, severity, and outcome of ischemic stroke, and thus there are guidelines for the optimal PT-INR range that is to be maintained during secondary or primary prevention of ischemic stroke. However, the details of ischemic stroke in patients in whom an optimal PT-INR is maintained by warfarin therapy have not been thoroughly investigated. We conducted a retrospective study to determine the predictors of the size, severity, and outcome of ischemic stroke occurring in pati...

Safety of Mechanical Thrombectomy for Acute Ischemic Stroke in Patients on Novel Oral Anticoagulants (P1.196)
Conclusion: Patients on NOAC undergoing mechanical thrombectomy show a trend towards increased sICH compared to the warfarin group. This may warrant larger studies of safety of mechanical thrombectomy in the presence of NOACs.Disclosure: Dr. Sharma has nothing to disclose. Dr. Atchaneeyasakul has nothing to disclose.

Antithrombotic Strategy in Cerebral Venous Thrombosis: Differences Between Neurologists and Haematologists in a Canadian Survey (P6.007)
Conclusions: In this cohort, there are differences between neurologists and hematologists with regards to initial choice of anticoagulant. It is possible that more complex presenting cases of CVT with concurrent venous infarction, hemorrhage or seizure may present to neurologists as compared to hematologists. Thus, an initial preference for UFH may reflect a desire for a reversible agent with a short half-life in the event of bleeding complications in an unstable patient. Our study is limited by response bias, though our response rate of 28[percnt] is comparable to other contemporary web-based physician surveys. The majori...

Antiphospholipid Syndrome-Associated Crescendo Stroke Events Treated with Rituximab (P4.351)
Discussion APS is an autoimmune condition associated with persistent antiphospholipid antibodies, characterised by thrombosis and pregnancy morbidity [1].Regarding APS and stroke the optimal antithrombotic agent, intensity of anticoagulation, and duration of treatment remains controversial[2]. Analysis of the APASS subgroup in the WARS study found aspirin and warfarin to be equally effective agents for secondary stroke prevention [2]. The majority of panel members at the International Congress on Antiphospholipid Antibodies recommended warfarin or combination aspirin and warfarin for patients with definite APS and arterial...

Aortic Sarcoma Mimicking a Thrombus Filling Vascular Lumen: A Rare Cause of Cerebral Infarction (P4.364)
Conclusion- Primary aortic sarcoma is an extremely rare cause of stroke. This sarcoma may be misinterpreted as a thrombus filling vascular lumen on CT angiography, but no elevation of D-dimer is incompatible with a large thrombus. The final diagnosis can be made by surgical biopsy.Disclosure: Dr. Kim has nothing to disclose. Dr. Jeon has nothing to disclose. Dr. Park has nothing to disclose. Dr. Kim has nothing to disclose.

Design and Rationale of the RELAXED (Recurrent Embolism Lessened by rivaroxaban, an Anti-Xa agent, of Early Dosing for acute ischemic stroke and transient ischemic attack with atrial fibrillation) Study
In the acute phase of cardioembolic stroke in patients with nonvalvular atrial fibrillation (NVAF), the recurrence rate is high. Nonvitamin K antagonist oral anticoagulants may be appropriate for prevention of early recurrence because they have a much lower risk of hemorrhagic stroke than warfarin.

Cardiovascular, Bleeding, and Mortality Risks of Dabigatran in Asians With Nonvalvular Atrial Fibrillation Clinical Sciences
Conclusions— In real-world practice, dabigatran was associated with a reduced risk of ischemic stroke, intracranial hemorrhage, all hospitalized major bleeding, and all-cause mortality compared with warfarin in Asian patients with nonvalvular atrial fibrillation. Dabigatran did not increase the risk of major gastrointestinal bleeding or myocardial infarction compared with warfarin.

Use of Warfarin at Discharge Among Acute Ischemic Stroke Patients With Nonvalvular Atrial Fibrillation in China Clinical Sciences
Conclusions— The rate of warfarin use remains low among patients with ischemic stroke and known nonvalvular atrial fibrillation in China. Hospital size and academic status together with patient age, heart failure, heavy alcohol drinking, international normalized ratio in hospital, and stroke severity on admission were each independently associated with the use of warfarin at discharge. There is much room for improvement for secondary stroke prevention in nonvalvular atrial fibrillation patients in China.

Puerperal Extracranial Vertebral Artery Dissection and Nonaneurysmal Subarachnoid Hemorrhage
Previously reported only a few times before, we present a case of extracranial vertebral dissection and spontaneous frontoparietal subarachnoid hemorrhage (SAH) in the puerperium, discussing possible mechanisms and difficulties in management. A 35-year-old woman presented 10 days postcaesarean section with neck pain and vertigo with normal initial investigations. Following recurrent vertigo, headache, and ataxia, imaging revealed a frontoparietal SAH and vertebral artery dissection. The patient was consequently treated with aspirin, and then following a return of symptoms 3 weeks later, warfarin therapy was continued for 6 months.

Multiple cerebral and cerebellar infarcts as the first clinical manifestation in a patient with Churg-Strauss syndrome: case report and literature review.
CONCLUSION: Symptoms and signs of central nervous system can be the initial neurological manifestation of CSS patients. CSS should be considered while patients have stroke and hypereosinophilia. In our patient, there is a good response to timely steroid, immunosuppressant and anticoagulant therapies. PMID: 23329548 [PubMed - indexed for MEDLINE]
