BACKGROUND: Von Willebrand disease (VWD) is the most common congenital bleeding disorder. This autosomal dominant condition arises from quantitative or qualitative defects of Von Willebrand factor. To our knowledge, this study leveraged a national database to characterize the largest VWD cohort of total hip arthroplasty (THA) patients to date, assessing 90-day postoperative adverse events and 5-year revision-free survival. METHODS: Adult patients who underwent primary THA for osteoarthritis were identified from January 2010 to October 2021 in a nationwide database...

OBJECTIVE: The perioperative management of patients on antiplatelet drugs is a rising challenge in orthopedic trauma because antiplatelet drugs are frequently encountered and carry an increased risk of hemorrhagic consequences. The study objective was to examine the effect of aspirin on bleeding outcomes for patients with lower extremity fractures. METHODS: This retrospective study included patients requiring surgical fixation of traumatic hip, femur, and tibia fractures from January 1, 2018, to March 1, 2020...

This systematic review addresses the crucial role of anticoagulation in microsurgical procedures, focusing on free flap reconstruction and replantation surgeries. The objective was to balance the prevention of thrombotic complications commonly leading to flap failure, with the risk of increased bleeding complications associated with anticoagulant use. A meticulous PubMed literature search following Evidence-Based-Practice principles yielded 79 relevant articles, including both clinical and animal studies. The full-texts were carefully reviewed and evaluated by the modified Coleman methodology score...

PURPOSE: Venous thromboembolism (VTE) is a known complication of hip arthroplasty for femoral neck fractures (FNF) with various prophylactic anticoagulants utilized to decrease risk. The purpose of this study was to assess the efficacy and perioperative outcomes associated with aspirin for VTE prophylaxis following arthroplasty for FNF. METHODS: Medical records of 1,220 patients who underwent hip hemiarthroplasty (HHA) or total hip arthroplasty (THA) at an urban academic center from 2011 to 2022 were retrospectively reviewed...

Microvascular free tissue transfer surgery is a frequently used technique for head and neck reconstruction involving anticoagulants, and the present study aimed to analyse the postoperative outcomes of aspirin use in conjunction with this procedure. We searched databases for articles published between 2007 and 2022 on microvascular free tissue transfer surgery using aspirin and assessed them for primary and secondary outcomes. Odds ratios (ORs) and 95 % confidence intervals (CIs) were determined through analyses, followed by constructing a forest plot for complication rates...

STUDY DESIGN: A retrospective cohort study. OBJECTIVE: To calculate the magnitude of any increased risk of epidural hematoma (EDH) associated with chemoprophylactic anticoagulation (chemoprophylaxis), if any. SUMMARY OF BACKGROUND DATA: Chemoprophylaxis for the prevention of venous thromboembolic events may be associated with an increased risk of EDH after spine surgery. MATERIALS AND METHODS: A total of 6869 consecutive spine surgeries performed at our institution were identified, and clinical and demographic data were collected...

BACKGROUND: Multiple studies have compared different pharmacologic thromboprophylaxis agents after hip fracture surgery, including aspirin, unfractionated heparin (UFH), low-molecular-weight heparin (LMWH), direct oral anticoagulants (DOAC), and warfarin, resulting in variability in clinical practice. To guide clinical management, a systematic review and network meta-analysis (NMA), which enables the simultaneous assessment of the effects of multiple interventions for the same patient population, was performed...

BACKGROUND: Major orthopedic surgery, including hip and knee replacement and lower extremity trauma fractures surgery, is associated with a high risk of venous thromboembolism (VTE), especially proximal deep vein thrombosis (DVT), and pulmonary embolism (PE), and is linked with high morbidity and mortality rates. Chemical anticoagulation is routinely used to prevent VTE, with previous meta-analyses reporting on the efficacy and safety of aspirin and other anticoagulants, however, opinions are divided...

Venous thromboembolism (VTE), comprising pulmonary embolism (PE) and deep vein thrombosis (DVT), poses a significant risk during and after hospitalization, particularly for surgical patients. Among various patient groups, those undergoing major orthopedic surgeries are considered to have a higher susceptibility to PE and DVT. Major lower-extremity orthopedic procedures carry a higher risk of symptomatic VTE compared to most other surgeries, with an estimated incidence of ~4%. The greatest risk period occurs within the first 7-14 days following surgery...

Regimens for managing thromboembolic complications of COVID-19 are still not very well established. The present study compares the clinical characteristics and outcomes of patients hospitalized with COVID-19 receiving different anticoagulation regimens with and without aspirin. This is a retrospective observational study of 491 patients hospitalized for COVID-19 from August 2020 to April 2021. Data regarding clinical characteristics, laboratory findings, and outcomes of patients receiving different anticoagulation with and without aspirin regimens was collected, according to which 5 patient groups were defined: received no anticoagulation (NAA), prophylactic anticoagulation with (PA) or without aspirin (PAA) and therapeutic anticoagulation with (TA) or without aspirin (TAA)...

Background: Out-of-hospital cardiac arrest (OHCA) has a high prevalence of obstructive coronary artery disease and total coronary occlusion. Consequently, these patients are frequently loaded with antiplatelets and anticoagulants before hospital arrival. However, OHCA patients have multiple non-cardiac causes and high susceptibility for bleeding. In brief, there is a gap in the evidence for loading in OHCA patients. Objective: The current analysis stratified the outcome of patients with OHCA according to pre-clinical loading...

In the last 10 years the introduction of the direct oral anticoagulants (DOACs) has revolutionized the anticoagulant treatment, one of the cornerstones of the therapy for cardiovascular diseases. Thanks to their efficacy at least not inferior compared to vitamin K antagonists and their better safety profile, particularly with regard to intracranial bleeding, DOACs are now the first choice for the prevention of cardioembolism in patients with non-valvular atrial fibrillation and for the treatment of venous thromboembolism (VTE)...

BACKGROUND AND AIMS: Acute infections cause relevant activation of innate immunity and inflammatory cascade. An excessive response against pathogens has been proved to trigger the pathophysiological process of thrombo-inflammation. Nevertheless, an association between the use of antithrombotic agents and the outcome of critically ill patients with infectious diseases is lacking. The aim of this meta-analysis is to determine the impact of antithrombotic treatment on survival of patients with acute infective disease...

OBJECTIVES: To examine the relationship between anticoagulant and antiplatelet drugs and surgical blood loss for geriatric patients undergoing cephalomedullary nail fixation of extracapsular proximal femur fractures. DESIGN: Multicenter retrospective cohort study using bivariate and multivariable regression analyses. SETTING: Two level-1 trauma centers. PATIENTS: 1442 geriatric (ages 60-105) patients undergoing isolated primary intramedullary fixation of non-pathologic extracapsular hip fractures from 2009 - 2018 including 657 taking an antiplatelet drug alone (including aspirin), 99 taking warfarin alone, 37 taking a direct oral anticoagulant (DOAC) alone, 59 taking an antiplatelet drug and an anticoagulant, and 590 taking neither...

OBJECTIVES: Data on the safety and efficacy of clopidogrel (CPD) monotherapy after coronary artery bypass grafting (CABG) are limited. We compared the clinical outcomes and graft patency rates during 4 years in CABG patients who maintained CPD or aspirin after 1 year of dual antiplatelet therapy (DAPT) use. METHODS: A total of 671 patients who maintained 1-year DAPT after CABG with all grafts patent on one-year follow-up angiography and switched to single antiplatelet therapy (SAPT) using CPD (n = 272) or aspirin (n = 399) between January 2009 and December 2015 were enrolled...

Postoperative venous thromboembolism is a major adverse event associated with orthopaedic surgery. With the addition of perioperative anticoagulation and antiplatelet therapy, the rates of symptomatic venous thromboembolism have dropped to 1% to 3%, and as such, practicing orthopaedic surgeons must be familiar with these medications, including aspirin, heparin, or warfarin, and the use of direct oral anticoagulants (DOACs). DOACs are increasingly being prescribed due to their predictable pharmacokinetics and increased convenience, as they do not require routine monitoring, and 1% to 2% of the general population is currently anticoagulated...

PURPOSE: Patients undergoing major orthopedic surgeries, such as total hip replacement (THR), total knee replacement (TKR), and trauma surgery, are at an elevated risk of venous thromboembolism (VTE), causing significant morbidity and mortality. Previous studies have investigated aspirin as a thromboprophylactic agent for arthroplasty, besides trauma surgery. Therefore, we sought to analyze the efficacy of aspirin compared to that of other anticoagulants for VTE prophylaxis in patients undergoing major orthopedic surgeries...

BACKGROUND: Fascia iliaca compartment block (FICB) is an effective method to treat pain in adult trauma patients with hip fracture. Of importance is the high prevalence of preinjury anticoagulants and antiplatelet medications in this population. To date, we have not identified any literature that has specifically evaluated the safety of FICB with continuous catheter infusion in patients on antiplatelet and/or anticoagulant therapy. The purpose of this study is to quantify the complication rate associated with FICB in patients who are actively taking prescribed anticoagulant and/or antiplatelet medications prior to injury and identify factors that may predispose patients to an adverse event...

Background: Congenital heart defects, such as atrial septal defects (ASDs) and patent foramen ovale (PFO), may increase the risk of embolic events in total hip or knee arthroplasty (THA/TKA). The objective of this study was to determine the 90-day incidence of intraoperative and postoperative embolic events and all other complications in patients with a known ASD/PFO who underwent primary hip and knee arthroplasty. Methods: This is a retrospective review of 160 patients with ASD/PFO undergoing 196 primary arthroplasties (94 THAs, 102 TKAs) at a single institution...

BACKGROUND: There is no consensus regarding postoperative anticoagulation after mitral valve repair (MVRep). We compared the outcomes of post-MVRep anticoagulation with apixaban compared to warfarin. METHODS: We reviewed data of 666 patients who underwent isolated robotic MVRep between January 2008 and October 2019. We excluded patients who had conversion to sternotomy and those discharged without anticoagulation or on clopidogrel (n = 40). Baseline and intraoperative characteristics and antiplatelet/anticoagulation records were collected...
