Article Abstract
About 10% of patients taking a chronic, oral anticoagulant therapy require an invasive procedure that can be associated with an increased risk for peri-interventional or perioperative bleeding. Depending on the risk for thromboembolism and the risk for bleeding, the physician has to decide whether the anticoagulant therapy should be interrupted or continued. Patient characteristics such as age, renal function and drug interactions must be considered. The perioperative handling of the oral anticoagulant therapy differs according to the periprocedural bleeding risk. Patients requiring a procedure with a minor risk for bleeding do not need to pause their anticoagulant therapy. For procedures with an increased risk for perioperative bleeding, the anticoagulant therapy should be adequately paused. For patients on a coumarin derivative with a high risk for a thromboembolic event, a perioperative bridging therapy with a low molecular weight heparin is recommended. Due to an increased risk for perioperative bleeding in patients on a bridging therapy, it is not recommended in patients with a low risk for thromboembolism. For patients taking a non-vitamin K oral anticoagulant, a bridging therapy is not recommended due to the fast onset and offset of the medication.
Prolongation of the activated partial thromboplastin time (aPTT) may signify an intrinsic factor deficiency or the presence of an inhibitor of coagulation, potentially placing a patient at increased risk for bleeding. However, a contact factor (ie, factor XII, prekallikrein, and high molecular weight kininogen) deficiency, which may also cause a prolonged aPTT, is not associated with clinical bleeding. A 71-year-old female had an isolated prolonged aPTT discovered during preoperative laboratory testing.
Introduction: Hepatic artery pseudoaneurysm (HAP) is a rare and potentially life-threatening condition associated with high mortality. This study aims to review the etiology, clinical manifestations, management, and outcomes of patients diagnosed and treated for HAP at the Mayo Clinic.
Methodology: This study was a retrospective chart review of medical records for patients diagnosed and treated for hepatic artery pseudoaneurysm (HAP) at the Mayo Clinic (Florida, Minnesota, and Arizona) between September 1, 1998, and June 30, 2022.
Purpose: Atrial fibrillation (AF) being a prevalent cardiovascular condition globally, has an increased risk of stroke and other complications. The effective management of AF often involves the use of oral anticoagulants (OACs) to prevent thromboembolic events. This study aimed to evaluate anticoagulation knowledge and medication adherence in AF patients on OACs at a tertiary care center in Nepal.
The benefits of permanent cardiac pacing have been widely demonstrated. However, the literature on complications remains inconsistent. We lack precise information about the frequency of complications and their predictive factors in our center.
Background: Venous thromboembolism (VTE) is a significant complication following total knee arthroplasty (TKA) and total hip arthroplasty (THA). Aspirin has gained attention as a cost-effective, safe alternative to traditional anticoagulants like enoxaparin, but comparative data on efficacy and safety remain limited.
Methods: This randomized controlled trial compared the efficacy of aspirin and enoxaparin in preventing VTE following TKA and THA.
