OBJECTIVE: To determine the likelihood that head injured patients on Warfarin with a negative initial head CT will have a positive repeat head CT. A retrospective chart review of our institution's trauma registry was performed for all patients admitted for blunt head trauma and on Warfarin anti-coagulation from January 2009 to April 2014. Inclusion criteria included patients over 18 years of age with initial GCS ≥ 13, INR greater than 1.5 and negative initial head CT. Initial CT findings, repeat CT findings and INR were recorded...

Background: Herbal supplements are commonly used, however, their side-effect profiles are poorly understood and not subject to the same scrutiny as prescribed medications. Some herbal supplements such as St Johns' Wort are accepted to interfere with clotting pathways, however others, including Red Clover have theoretical bleeding risks based on coumarin content with very little underlying evidence. Case Description: This case reports a 65-year-old woman who suffered a spontaneous acute-on-chronic subdural hemorrhage with a significant postoperative re-hemorrhage...

OBJECTIVE: To examine the comparative safety of individual NSAIDs when given concomitantly with clopidogrel. METHODS: We conducted a retrospective cohort study using Medicaid claims from five US states during 1999-2010, supplemented with Medicare claims for dual-enrollees. The exposure of interest was the first concomitant use of clopidogrel and one of the 10 selected NSAIDs after a 1-year baseline period. The outcomes were: all-cause mortality; acute myocardial infarction (AMI)/ischemic stroke; and gastrointestinal bleeding (GIB)/intracranial hemorrhage (ICH)...

Although there are several reports of intracranial hemorrhage associated with vitamin K deficient bleeding, there are few reported cases of extracranial manifestations, specifically involving the thymus. Here, we discuss the unique case of a 4-week-old infant presenting with scrotal discoloration, respiratory distress, and widened mediastinum, found to have thymic hemorrhage related to confirmed coagulopathy secondary to late-onset vitamin K deficiency bleeding of the newborn.

OBJECTIVES: The aim of this prospective study is to investigate the central nervous system involvement in Crimean-Congo haemorrhagic fever (CCHF) with magnetic resonance imaging (MRI) in conjunction with clinical and laboratory findings. METHODS: Between July 2015 and August 2016, 36 patients with CCHF were undergone brain MRI including SWI. Two MRIs, one at the time of admission and the second in the convalescent period, were performed for each patient in order to see if there is any sign of central nervous system (CNS) involvement, especially in terms of intracranial haemorrhage or viral encephalitis...

CHA2 DS2 -VASc and HAS-BLED scores stratify the risk of thromboembolic and bleeding events respectively in patients with atrial fibrillation. There is only little information on how they differentiate which of the 2 clinically most important complications (ischemic stroke [IS] or an intracranial bleeding [IB]) the patient is more prone to suffer. We evaluated both scores in patients with either of these major complications. The FibStroke Study collected data on all patients with atrial fibrillation with either an IS or an IB event between 2003 and 2012 in 4 Finnish hospital districts...

The actual heparin concentration of harvested allogeneic bone marrow varies among harvest centers. We monitor the activated partial thromboplastin time (APTT) of the patient during bone marrow infusion and administer prophylactic protamine according to the APTT. We retrospectively reviewed the charts of consecutive patients who underwent bone marrow transplantation without bone marrow processing at our center between April 2007 and March 2016 (n=94). APTT was monitored during marrow transfusion in 52 patients...

BACKGROUND: Different strategies exist for dosing four-factor prothrombin complex concentrate (PCC4) for international normalized ratio (INR) reversal in the setting of life-threatening bleeding. Fixed doses ranging from 1000 IU to 1750 IU have demonstrated efficacy similar to weight-based dosing, however, few studies look exclusively at intracranial hemorrhage (ICH). OBJECTIVE: Our aim was to evaluate whether a fixed dose of 1000 IU of PCC4 achieves INR reversal similar to weight-based dosing in patients with ICH who were anticoagulated with warfarin...

BACKGROUND: Factor Xa inhibitors and vitamin K antagonists (VKAs) are now recommended in treatment guidelines for preventing stroke and systemic embolic events in people with atrial fibrillation (AF). This is an update of a Cochrane review previously published in 2013. OBJECTIVES: To assess the effectiveness and safety of treatment with factor Xa inhibitors versus VKAs for preventing cerebral or systemic embolic events in people with AF. SEARCH METHODS: We searched the trials registers of the Cochrane Stroke Group and the Cochrane Heart Group (September 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) (August 2017), MEDLINE (1950 to April 2017), and Embase (1980 to April 2017)...

Traumatic brain injury (TBI)-induced coagulopathy is a common and well-recognized risk for poor clinical outcomes, but its pathogenesis remains poorly understood and treatment options are limited and ineffective. We discuss the recent progress and knowledge gaps in understanding this lethal complication of TBI. We focus on (1) the disruption of the brain-blood barrier to disseminate brain injury systemically by releasing brain-derived molecules into the circulation and (2) TBI-induced hypercoagulable and hyperfibrinolytic states that result in persistent and delayed intracranial hemorrhage and systemic bleeding...

AIMS: The aim of this study was to determine the net clinical benefit (NCB) of rivaroxaban compared with warfarin in patients with atrial fibrillation. METHODS: This was a retrospective analysis of 14,236 patients included in ROCKET AF who received at least one dose of study drug. We analyzed NCB using four different methods: (1) composite of death, stroke, systemic embolism, myocardial infarction, and major bleeding; (2) method 1 with fatal or critical organ bleeding substituted for major bleeding; (3) difference between the rate of ischemic stroke or systemic embolism minus 1...

Clinical significance of potential interaction between warfarin and statins is unclear. Our objective was to determine whether use of statins as a class or use of simvastatin modulates the rate of bleeding requiring hospitalisation among new warfarin users. Using Finnish healthcare databases, we identified a cohort of 101,588 warfarin initiators between 1 January 2009 and 30 June 2012. By the end of 2012, these patients accumulated 92,695 person-years of exposure to warfarin-only and 60,253 years of exposure to warfarin-with-statin...

Tissue plasminogen activator (tPA) has been reported to treat intraoperative pulmonary thromboembolism (PTE) during liver transplantation (LT). However, tPA administration is often delayed due to fear of uncontrolled bleeding and storage in a refrigerator outside of operating rooms. Various dosages of tPA were used. We hypothesize that a policy of tPA storage and low dosage use improves patient outcomes. At a transplantation center, a multidisciplinary committee has implemented a tPA policy since April 2014, which includes the following: (1) timely administering of low-dose tPA (0...

Pulmonary embolism is a life-threatening condition treated with anticoagulation and systemic thrombolysis when appropriate. In patients with contraindications to thrombolysis, catheter-directed thrombolysis may be considered. Here, we present a patient with massive pulmonary embolus and 3 contraindications to systemic thrombolysis who was successfully treated with pharmacomechanical thrombolysis using the Ekosonic Endovascular System.

Herein, the authors report a rare patient with a transnasal intracranial penetration injury caused by a chopstick that resulted in optic nerve transection as well as the removal of the chopstick using a bidirectional approach. A 25-year-old male presented to our emergency department with right blindness and bilateral epistaxis. Preoperative computed tomographic angiography demonstrated a transnasal stick-like foreign body causing a skull base fracture and suspected vascular injury. Due to the shape of the chopstick and the high risk of massive bleeding, an exclusively endoscopic or open craniotomy approach is not suitable for removal...

Intracranial haemorrhage (ICH) is the most dreadful complication, and the main cause of death among patients with rare bleeding disorders (RBD) and prenatal diagnosis (PND) is a preventative lifesaving program. A total of 39 PNDs were reported in the literature through a search on PubMed, EMBASE, SCOPUS and Web of Science databases, most often for congenital factor (F) XIII and FVII deficiencies and rarely in FX, FV deficiencies and afibrinogenemia. The main cause to request a PND is ICH and related morbidity and mortality...
