Cerebral infarction following administration of andexanet alfa for anticoagulant reversal in a patient with traumatic acute subdural hematoma.

Background: Anticoagulants prevent thrombosis in patients with atrial fibrillation (AF) and venous thromboembolism but increase the risk of hemorrhagic complications. If severe bleeding occurs with anticoagulant use, discontinuation and rapid reversal are essential. However, the optimal timing for resuming anticoagulants after using reversal agents remains unclear.

Primary Antiphospholipid Antibody Syndrome Complicated with Cerebellar Hemorrhage and Aortic Dissection: A Case Report.

BACKGROUND Antiphospholipid antibody syndrome (APS) is a systemic autoimmune disease associated with arterial and venous thromboembolism and pregnancy complications. There have been several reports of APS with systemic lupus erythematosus (SLE) complicated with aortic dissection. However, none of them has been primary APS, which is APS without SLE.

Add-on Antiplatelet Effects of Eicosapentaenoic Acid With Tailored Dose Setting in Patients on Dual Antiplatelet Therapy.

The aim of this study was to investigate the antiplatelet effects of eicosapentaenoic acid (EPA) at a sufficient dose following coronary stent implantation. Thirty-one patients on dual antiplatelet therapy with aspirin and clopidogrel were treated with highly purified EPA-E (Epadel) for 12 weeks. Based on our previous study, patients with a high baseline EPA/arachidonic acid (AA) ratio (≥ 0.

Hyper-Response to Clopidogrel in Japanese Patients Undergoing Transcatheter Aortic Valve Implantation.

Dual antiplatelet therapy is empirically recommended following transcatheter aortic valve implantation (TAVI). The aims of the present study were to analyze the effect of clopidogrel on platelet function and to determine the relative contribution of each CYP2C19 loss-of-function genotype undergoing TAVI.Thirty-two patients undergoing TAVI and with clopidogrel treatment were studied.

Quantitative optical coherence tomography analysis for late in-stent restenotic lesions.

Coronary optical coherence tomography (OCT) has the potential to identify in-stent neoatherosclerosis, which is a possible risk factor for late acute coronary events after drug-eluting stent implantation. The purpose of this study was to investigate differences between mid-term and late in-stent restenosis after stent implantation by quantitative and semiautomated tissue property analysis using OCT. In total, 1063 OCT image frames of 16 lesions in 15 patients were analyzed.

Effects of eicosapentaenoic acid on platelet function in patients taking long-term aspirin following coronary stent implantation.

Eicosapentaenoic acid (EPA) has been widely accepted to have antiatherosclerotic effects. The aim of this study was to investigate the antiplatelet effect of EPA combined with acetylsalicylic acid (ASA) following stent implantation. Eighteen patients who had undergone coronary stent implantation at least 8 months previously were included.

Predominant microvessel proliferation in coronary stent restenotic tissue in patients with diabetes: insights from optical coherence tomography image analysis.

Background: Coronary optical coherence tomography (OCT) enables virtual depiction of histological findings of in-stent restenotic tissue. The aim of this study was to investigate the microvessel proliferation within in-stent restenotic tissue and the influence of diabetes mellitus (DM).

Methods: We examined 54 in-stent restenotic coronary artery lesions (stenotic area>50%) from 50 consecutive patients including 28 with DM (56%) and 9 insulin-treated DM patients (18%); who underwent coronary time-domain OCT imaging with automatic pull back (1mm/s, 20 frames/s).

Angiographic and clinical outcomes of 100 consecutive severe calcified lesions requiring rotational atherectomy prior to sirolimus-eluting stent implantation in hemodialysis and non-hemodialysis patients.

Both severe calcified lesions and hemodialysis (HD) are predictors for high rates of restenosis, even in the drug-eluting stent era. We sought to investigate the angiographic and clinical outcome in a population of HD versus non-hemodialysis (non-HD) patients with severe calcified lesions requiring rotational atherectomy. One hundred consecutive lesions (28 lesions in the HD group, 72 in the non-HD group) from 82 patients (19 patients in the HD group, 63 in the non-HD group) requiring rotational atherectomy prior to sirolimus-eluting stent (SES) implantation were analyzed post-procedure and at 8 months.

Effect of cilostazol on optimized standard antiplatelet therapy in a patient with a cytochrome P450 2C19 *2/*2 genotype.

A 54-year-old man with acute coronary syndrome underwent primary percutaneous coronary intervention (PCI) to implant a bare metal stent. Three weeks later, a subclinical in-stent thrombus was found at staged PCI despite dual antiplatelet therapy with aspirin and clopidogrel. Platelet function tests revealed high post-treatment platelet reactivity, indicating an inadequate response to clopidogrel.

Comparison of platelet P2Y(12) ADP receptor-mediated pathway inhibition in triple versus dual antiplatelet therapy as assessed by VASP-phosphorylation in Japanese patients undergoing coronary stenting.

Despite wide interindividual variability in response to clopidogrel, platelet P2Y(12) ADP receptor inhibition in Japanese patients has not been fully studied using specific methodology. This study compared platelet P2Y(12) ADP receptor inhibition during treatment with clopidogrel versus clopidogrel plus cilostazol in patients undergoing coronary stenting. Forty-two patients in whom platelet function was measured within 2 months after coronary stenting were enrolled.

Enhanced platelet activation following coronary stent implantation in patients on hemodialysis.

Hemodialysis ("HD") has been suggested as a risk factor for stent thrombosis. However, platelet function in HD patients after coronary stent implantation remains unclear. The aim of this study was to evaluate platelet function following coronary stent implantation in HD patients.

Serial quantitative coronary analyses for the evaluation of one-year change in saphenous vein grafts.

Background: A paucity of data exists with respect to changes in whole saphenous vein grafts (SVGs) despite accelerated atherosclerosis within grafted saphenous vein conduits. In the present study, we evaluated the one-year change in SVGs by means of quantitative coronary analysis.

Methods: This study enrolled consecutive 52 patients with 109 SVGs, who underwent coronary artery bypass graft surgery successfully.

[A case of infant epidural hematoma treated by continuous drainage of cephalohematoma].

A female infant was born at 36 weeks with vacuum extraction. Her weight was 2.216 g and Apgar score was 9.

Intravascular ultrasound analysis of the radial artery for coronary artery bypass grafting.

Background: The radial artery has become a popular conduit for coronary artery bypass surgery. However, limited information has been provided regarding the atherosclerotic nature of this artery, which may affect both the immediate intraoperative difficulties and long-term graft patency.

Methods: We examined intravascular ultrasound (IVUS) images of the radial artery in patients with coronary artery diseases.

[Changes in peripheral lymphocytes count in unconscious patients treated at home with Japanese herbal medicines (Hozai)].

We investigated changes in peripheral white blood cells count, lymphocytes count, and serum albumin level in five unconscious patients administered Japanese herbal medicines (Hozai). The causes of unconsciousness were intracerebral hemorrhage in 3, cerebral infarction in 1, and craniopharyngioma in 1. The administered Hozai were Hotyu-ekki-to in 4 and Jyuzen-taiho-to in 1.
