The risk of perioperative bleeding is high in patients who take aspirin and clopidogrel after a percutaneous coronary intervention, and whether to stop the drugs is a matter of concern for dentists. The aim of this study was to answer the specific question: should aspirin and clopidogrel bisulphate (Plavix®) be discontinued during a conventional forceps extraction? We studied 64 patients during the first year after percutaneous insertion of coronary stents who were taking aspirin (ASA) 80mg and clopidogrel (Plavix(®)) 75mg, and 50 healthy patients who were to have a conventional forceps extraction at this polyclinic in 2013-2014 and acted as controls...

INTRODUCTION: Clopidogrel (Plavix(®)) may influence patient safety during fracture surgery. Our study examines the incidence of complications for patients undergoing hemiarthroplasty on clopidogrel therapy. MATERIALS AND METHODS: All patients, who underwent hemiarthroplasty between 2005 and 2011 were retrospectively reviewed. Patients were placed in two comparative groups based on the use of clopidogrel antiplatelet therapy. Records were reviewed for patient demographics, ASA score, pre and postoperative hemoglobin, time to surgery, length of stay, bleeding events, transfusions and complications...

OBJECTIVES: Ticagrelor (Brilique®) is a novel reversible platelet inhibitor at P2Y12 receptor used in patients with acute coronary syndrome and patients undergoing percutaneous coronary interventions. Unlike clopidogrel (Plavix®), ticagrelor has a quicker offset of action, and therefore, it seems that platelet function recovers faster on discontinuation of therapy. These drugs sometimes cannot be stopped before coronary artery bypass grafting due to the risk of stent thrombosis or in case of emergency operations...

OBJECTIVES: The purpose of this study was to assess the safety and efficacy of left atrial appendage (LAA) closure in nonvalvular atrial fibrillation (AF) patients ineligible for warfarin therapy. BACKGROUND: The PROTECT AF (Watchman Left Atrial Appendage System for Embolic Protection in Patients With Atrial Fibrillation) trial demonstrated that LAA closure with the Watchman device (Boston Scientific, Natick, Massachusetts) was noninferior to warfarin therapy. However, the PROTECT AF trial only included patients who were candidates for warfarin, and even patients randomly assigned to the LAA closure arm received concomitant warfarin for 6 weeks after Watchman implantation...

The aim of this health economic analysis was to compare the cost-effectiveness of ticagrelor versus clopidogrel within the German health care system. A two-part decision model was adapted to compare treatment with ticagrelor or clopidogrel in a low-dose acetylsalicylic acid (ASA) cohort (≤150 mg) for all ACS patients and subtypes NSTEMI/IA and STEMI. A decision-tree approach was chosen for the first year after initial hospitalization based on trial observations from a subgroup of the PLATO study. Subsequent years were estimated by a Markov model...

UNLABELLED: Antithrombotic therapy with oral aspirin (ASA) or clopidogrel (CLO) (Plavix; Bristol-Myers Squibb, Bridgewater, NJ) is associated with an attenuated skin vasodilator response and a greater rate of rise in core temperature in healthy, middle-age individuals during passive heating in a water perfused suit. PURPOSE: The present double-blind, crossover study examined the functional consequences of 7 d of low-dose ASA (81 mg·d) versus CLO (75 mg·d) treatment in 14 healthy, middle-age (50-65 yr) men and women during passive heating in air (40 min at 30°C, 40% relative humidity) followed by exercise (60% V˙O2peak)...

BACKGROUND AND IMPORTANCE: Carotid body tumors are a technically challenging surgical problem. One of the primary goals of surgery and often one of the most difficult aspects of management involves preservation of the ipsilateral internal carotid artery (ICA). We report a small case series with challenging aspects to ICA preservation that were successfully treated with covered stenting and review the literature to date on this topic. CLINICAL PRESENTATION: Two patients with carotid body tumors were selected for covered ICA stenting, the first because of bilateral disease and the second because of failure of test occlusion...

We report the endovascular treatment of a symptomatic dural arteriovenous fistula in a 61- year-old male patient. The medial portion of the fistula was occluded with detachable platinum coils during an initial intervention using a transvenous approach. Due to persistence of the symptoms in a second intervention eight months later the fistula was completely occluded by the transvenous introduction of a liquid embolic agent (Onyx 500+). The liquid embolic agent was introduced under protection by the temporary balloon occlusion of the fistula's venous drainage...

Patients undergoing percutaneous coronary intervention procedures, as in patients with coronary disease, should receive treatment indefinitely with acetylsalicylic acid and clopidogrel. New brands of clopidogrel have been developed at lower costs, for helping to avoid premature suspension of antiplatelet therapy, as Cravid Leti Laboratories clopidogrel. Its effectiveness and safety must be compared with Plavix international standard. A prospective, comparative, cross-over, and randomized study was conducted in healthy volunteers...

BACKGROUND: The mortality risk in elderly patients who sustained head trauma resulting in intracranial hemorrhage (ICH) while taking the antiplatelet agents aspirin (ASA) or clopidogrel or both (Plavix) was evaluated. METHODS: A retrospective review identified trauma patients, age 50 or greater, who had computed tomography (CT) evidence of ICH and were taking ASA, clopidogrel, or a combination of both. Patient demographics, type of medication, mechanism of injury, Glasgow Coma Score (GCS), grading of head CT scans, and outcomes were characterized...

BACKGROUND: Clinical manifestations of spontaneous retroperitoneal hemorrhage (SRH) range from a small decrease in hemoglobin to hypotension requiring transfer to the intensive care unit (ICU). Our goal was to identify which anticoagulated patients are at increased risk for SRH and its complications. METHODS: We conducted a retrospective review of 180 patients with SRH. Age, sex, presence of comorbidities, hemoglobin decrease, transfusion requirement, ICU stay, and length of ICU stay were recorded...

BACKGROUND: Clopidogrel is widely used in diabetic patients after vascular events; however, the ability of this thienopyridine to yield additional antiplatelet protection on top of aspirin has never been explored in a controlled study with comprehensive assessment of platelet activity. The objective of this study was to compare the antiplatelet profiles of clopidogrel + aspirin in combination (C + ASA) versus aspirin alone (ASA) in patients with type 2 diabetes mellitus. METHODS: Seventy patients with documented diabetes already treated with antecedent aspirin were randomly assigned to receive C + ASA or ASA in the PLUTO-Diabetes trial...

Platelet rich plasma (PRP) is being used with increased frequency in many surgical procedures for its known benefits of accelerated surgical wound site healing. Speculations in its efficacy in the presence of anti-platelet therapy have been proposed. To aid in defining a quality platelet rich plasma product in the presence of acetylsalicylic acid (ASA) and Plavix (clopidogrel bisulfate), we investigated three (3) groups (n = 18) of cardiac surgical patients receiving PRP. Platelet function test, platelet concentration, and quantification of growth factors (PDGF-bb and TGF-b1) were evaluated...

BACKGROUND: Transplant surgery often requires an effective preoperative treatment which allows to reduce the risk of bleeding caused by platelet aggregation inhibitors without major delay. The use of recombinant activated coagulation factor VIIa (rFVIIa) may be a future treatment option in such patients. METHOD: Five patients with end-stage renal disease on treatment with platelet aggregation inhibitors (ASA, Plavix, Aggrenox), who were scheduled for renal transplantation and received a preoperative bolus of recombinant factor VIIa (rFVIIa, NovoSeven) in a dose of 3 kIU/kg (60 microg/kg), were retrospectively analyzed...

Clopidogrel (Plavix) is a selective inhibitor of adenosine diphosphate-induced platelet aggregation. In patients with acute coronary syndromes (ACS) [unstable angina or non-ST-segment elevation myocardial infarction], clopidogrel plus aspirin (acetylsalicylic acid) for up to 1 year significantly reduced the risk of cardiovascular events relative to placebo plus aspirin in the well designed clinical trial CURE (Clopidogrel in Unstable angina to prevent Recurrent Events) and its substudy in patients undergoing percutaneous coronary intervention (PCI) [PCI-CURE]...

BACKGROUND AND PURPOSE: Clopidogrel is widely used in patients after recent ischemic stroke; however, its ability to yield additional antiplatelet protection on top of aspirin has never been explored in a controlled study. To determine whether clopidogrel with aspirin (C+ASA) will produce more potent platelet inhibition than aspirin alone (ASA) in patients after ischemic stroke, we conducted the Plavix Use for Treatment of Stroke trial. METHODS: Seventy patients after ischemic stroke were randomly assigned to C+ASA or ASA groups...

Irrespective of their mechanism of action, anticoagulants reduce the formation and action of thrombin. Thus they interfere with a final step in coagulation. Among platelet inhibitors only the GPIIb/IIIa antagonists inhibit the common pathway of aggregation, namely the formation of platelet-to-platelet bridges which are mediated by fibrinogen or von Willebrand factor. In contrast, acetylsalicylic acid (ASA), NSAIDs, clopidogrel (Plavix) or ticlopidine (Tyklid) inhibit platelet activation by abrogating the formation or action of a secondary platelet agonist, namely of thromboxane A(2) or ADP...

BACKGROUND: The incidence of clinically significant thromboembolic events due to the use of cardiac assist device systems remains high. Despite the considerable advances in cardiac assist device technology, the monitoring and management of the hypercoagulable coagulation status, resulting from foreign surfaces of the assist device system, altered rheologic conditions, and blood stasis in the recipient heart remain a challenge. Moreover septic complications and insufficient anticoagulation are responsible for thromboembolic events...

BACKGROUND: Persistent platelet activation may contribute to thrombotic events in patients with congestive heart failure (CHF). Chronic use of mild platelet inhibitors could therefore represent an independent avenue to improve morbidity, mortality, and quality of life in this expanding population. Although clopidogrel is widely used in patients with acute coronary syndromes and ischemic stroke, the ability of this novel ADP-receptor antagonist to inhibit platelet function in patients with CHF is unknown...
