Genetic and Non-Genetic Factors Affecting the Quality of Anticoagulation Control and Vascular Events in Atrial Fibrillation.
Warfarin has a narrow therapeutic window. We hypothesized that genetic factors related to warfarin metabolism (CYP2C9) and activity (VKORC1) would show stronger associations than modifiable factors with the quality of anticoagulation control and risks for thromboembolism and hemorrhage. ⋯ Both genetic factor (VKORC1 genotype) and clinical efforts (anticoagulation service) influenced the quality of anticoagulation control. However, clinical events were more strongly associated with patient characteristics and clinical efforts than with genetic factors.

Ischemic Stroke Mortality Is More Strongly Associated with Anemia on Admission Than with Underweight Status.
Underweight patients have recently been reported as a group with a high risk of poststroke death. Anemia also increases mortality rates in stroke patients. However, the causal associations between body weight and anemia resulting in stroke-related death remain unclear. We examined the association of weight status and hemoglobin levels with 3-month mortality after ischemic stroke. ⋯ Anemia on admission was associated with stroke mortality independent of underweight status.

Case ReportsAcute Stroke Despite Dabigatran Anticoagulation Treated with Idarucizumab and Intravenous Tissue Plasminogen Activator.
Dabigatran is a direct thrombin inhibitor used to reduce the risk of stroke in patients with nonvalvular atrial fibrillation. For patients who present with an acute stroke despite dabigatran therapy, clinical data on the use of intravenous tissue plasminogen activator (IV-tPA) is limited. There is an anticipated increased risk of symptomatic intracranial hemorrhage (sICH) when using IV-tPA in patients on dabigatran therapy. ⋯ The patient was discharged with an NIHSS of 1. Telephone follow-up 2 months later indicated that he was at his prestroke baseline, except for a complaint of worsened short-term memory. Idarucizumab reversal of dabigatran may reduce the risk of sICH and should be considered for acute stroke patients arriving in the IV-tPA time window.

Randomized Controlled Trial Multicenter StudyThe Association Between Leukoaraiosis and Poor Outcome in Intracerebral Hemorrhage Is Not Mediated by Hematoma Growth.
The significance of white matter lesions (WMLs) in intracerebral hemorrhage (ICH) remains unclear. We investigated the effects of WML on initial hematoma volume, hematoma growth, intraventricular extension, and clinical outcome in patients with spontaneous ICH. ⋯ WMLs were not associated with initial hematoma volume, hematoma growth, or intraventricular extension. WMLs were associated with poor outcome independently.

Case ReportsClipping in Awake Surgery as End-Stage in a Complex Internal Carotid Artery Aneurysm After Failure of Multimodal Endovascular and Extracranial-Intracranial Bypass Treatment.
Intracranial carotid artery aneurysm can be treated via microsurgical or endovascular techniques. The optimal planning is the result of the careful patient selection through clinical, anatomic, and angiographic analysis. ⋯ ICA aneurysms could become complex aneurysms following multi-treatment failure. Endovascular approaches to treat ICA aneurysms include coiling, stenting, flow diverter stenting, and stenting-assisted coiling technique. The role of surgery remains relevant. To avoid severe neurologic deficits, recurrence, and the need of retreatment, a multidisciplinary discussion with experienced endovascular and vascular neurosurgeons is mandatory in such complex cases.
