Thrombus formation can lead to heart attacks, stroke and pulmonary embolism, which are major causes of mortality. Current standard diagnostic imaging methods detect anatomic abnormalities such as vascular flow impairment but have limitations. By using a targeted molecular imaging approach critical components of a pathology can be selectively visualized and exploited for an improved diagnosis and patient management. The GPIIb/IIIa receptor is abundantly and specifically exposed on activated platelets and is the key receptor in thrombus formation...

OBJECTIVE: To evaluate the efficacy and safety of one dose tranexamic acid combined with temporary drain lamping in primary unilateral total knee arthroplasty. METHODS: Total 160 patients undergoing unilateral primary total knee arthroplasty between January 2012 and December 2013 were randomly divided into four groups(40 cases in each group):group A (the drain was clamped for 2 hours after the operation and the patients received 20 ml physiological saline), group B(the drain was clamped for 2 hours after the operation and the patients received 10 ml tranexamic acid and 10 ml physiological saline), group C (the drain was clamped for 4 hours after the operation and the patients received 20 ml physiological saline) and group D(the drain was clamped for 4 hours after the operation and the patients received 10 ml tranexamic acid and 10 ml physiological saline)...

Clinical studies using total artificial hearts (TAHs) have demonstrated that pediatric and adult patients derive quality-of-life benefits from this form of therapy. Two clinically-approved TAHs and other pumps under development, however, have design challenges and limitations, including thromboembolic events, neurologic impairment, infection risk due to large size and percutaneous drivelines, and lack of ambulation, to name a few. To address these limitations, we are developing a hybrid-design, continuous-flow, implantable or extracorporeal, magnetically-levitated TAH for pediatric and adult patients with heart failure...

BACKGROUND: Although thrombosis complication is rare after arthroscopic meniscus surgery, deep vein thrombosis and pulmonary embolism can be fatal. The associated risk factors and whether anticoagulant prevention after arthroscopic knee surgery is necessary have not reach consensus. Here we present a case of deep vein thrombosis and pulmonary embolism after a common arthroscopic meniscectomy. CASE PRESENTATION: The patient had no risk factors except ipsilateral leg varicose veins...

BACKGROUND: Pulmonary embolism (PE) clinical decision rules do not consider a patient's family history of venous thromboembolism (VTE). We evaluated whether a family history of VTE predicts acute PE in the emergency department (ED). METHODS: Over a 5.5-year study period, we enrolled a prospective convenience sample of patients presenting to an academic emergency department with chest pain and/or shortness of breath. We defined a family history of VTE as a first-degree relative with previous PE or deep vein thrombosis (DVT)...

With the emergence of evidence that venous thromboembolisms (VTE) typically occurs following discharge after urologic pelvic surgery, the focus on extended VTE prophylaxis has intensified. Urologists should have a comprehensive understanding of various VTE risk factors in order to weigh the risk of postoperative hemorrhage with the possibility of fatal pulmonary embolus. Risk factors such as advanced age, obesity, and active malignancy are especially common in patient's undergoing urologic pelvic surgery, and thus this issue becomes particularly relevant to the practicing urologist...

PURPOSE OF REVIEW: Deep vein thrombosis (DVT) and pulmonary embolus are major causes of hospital-related morbidity and mortality, and are recognized as complications in patients with traumatic injury. Despite the significant morbidity and mortality associated with DVTs, prophylaxis and treatment are still not well understood and remain the subject of research and debate. RECENT FINDINGS: Elements of the patient's history and physical examination, along with thromboelastography, can be used to predict patients who are at greatest risk of DVT and venous thromboembolism (VTE)...

According to recent studies, lung uptake of iodine-123-metaiodobenzylguanidine (123I-MIBG) is impaired in many lung diseases and low lung uptake of 123I-MIBG suggests endothelial dysfunction of the pulmonary artery. 123I-MIBG scintigraphy in patients with pulmonary hypertension (PH) has not yet been clinically evaluated. We hypothesized that the lung uptake of 123I-MIBG is reduced in patients with PH and differs among PH subtypes. The purpose of the present study was to analyze the lung uptake of 123I-MIBG in patients with PH and compare it with the data obtained by echocardiography or right heart catheterization...

OBJECTIVE: Venous thromboembolism remains one of the leading causes of maternal mortality in the developed world. Retrievable inferior vena cava (IVC) filters have a role in the prevention of lethal pulmonary emboli when anticoagulation is contraindicated or has failed [1]. It is unclear whether or not the physiological changes in pregnancy influence efficacy and complications of these devices. The decision to place an IVC filter in pregnancy is complex and there is limited information in terms of benefit and risk to the mother...

Pulmonary arterial hypertension (PAH) is a rare disorder that can be drug-induced, mostly following treatment by appetite-suppressant drugs. We report four cases of patients who developed PAH following a treatment by leflunomide for rheumatoid arthritis, psoriatic arthritis or undetermined connective tissue disease. All patients described a progressive dyspnea from grade II to IV of NYHA classification; clinical examination found signs of heart failure. PAH was finally diagnosed and confirmed by right heart catheterisation...

BACKGROUND: Balloon pulmonary angioplasty (BPA) is an emerging interventional treatment option for chronic thromboembolic pulmonary hypertension (CTEPH). The non-invasive monitoring of CTEPH patients is a clinical challenge. In this study we examined changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients undergoing BPA for inoperable CTEPH and related them to peri-procedural success. METHODS: In this study we analyzed a total of 51 consecutive patients who underwent BPA treatment and completed a 6-month follow-up (6-MFU) between March 2014 and March 2017...

Acute pulmonary embolism (APE) is frequently reported in patients with cardiac arrest (CA) in emergency care. Pneumocyte apoptosis is commonly observed in the lungs following an APE. An important pathological mechanism evoking apoptosis during a lipopolysaccharide‑induced acute lung injury is the angiotensin‑converting enzyme 2 (ACE2)/ACE imbalance. The present study uses a porcine model to examine the anti‑apoptotic effects of captopril on APE‑CA and the return of spontaneous circulation (ROSC). Pigs were randomly assigned into four groups: Control, APE‑CA, ROSC‑saline, and ROSC‑captopril...

Pulmonary thromboembolism is common and missed by clinicians. We report a case of massive pulmonary embolism which was life threatening treated by the catheter assisted technique. Anticoagulation is the mainstay of therapy for most patients, with thrombolytic therapy reserved for some patients.1 Recent studies have suggested a role for systemic or catheter-directed thrombolytic therapy in selected patients.2 We present a case of a patient who presented with an PE, was successfully treated with catheter-directed thrombolysis...

In patients with solid tumours or haematological malignancies, venous thromboembolism (VTE) is a leading cause of death and significantly contributes to morbidity and healthcare resource utilization. Current practice guidelines recommend long-term anticoagulation with low-molecular-weight heparin (LMWH) as the treatment of choice for cancer-associated VTE, based on clinical trial data showing an overall improved safety and efficacy profile of LMWH compared to vitamin K antagonists. However, several open questions remain, e...

A retrospective review of three patients with acute respiratory distress syndrome (ARDS) and normal baseline right ventricular function admitted to the Cardiac Surgery Intensive Care Unit whom developed acute cor pulmonale while on veno-venous extracorporeal membrane oxygenation. These patients were diagnosed with ARDS using Berlin Criteria definitions and cannulated with a dual lumen (Avalon) cannula. Despite variations in history, presentation, and course, findings of acute cor pulmonale were encountered 4 to 6 weeks after extracorporeal membrane oxygenation cannulation...

Antiphospholipid syndrome (APS) is a cause of chronic thromboembolic pulmonary hypertension (CTEPH) and it is associated with an increased risk of postoperative neurological complications. We experienced a case of reversible parkinsonism after pulmonary endarterectomy (PEA) and subsequent multiple cerebral infarctions under standard anticoagulation therapy in a patient with CTEPH associated with APS. Strict management using a combination of antiplatelet and anticoagulation therapy should be considered in patients with a high titer of triple antiphospholipid antibodies in the perioperative period...

Extrinsic compression of the left main coronary artery (LMCA) can occur in patients with an enlarged pulmonary artery trunk secondary to severe pulmonary hypertension (PH). This phenomenon rarely occurs in PH; moreover, few reports have shown that chronic thromboembolic PH can be a triggering factor for this syndrome. Herein, we describe a patient with extrinsic compression of the LMCA with chronic thromboembolic PH who underwent pulmonary endarterectomy and coronary artery bypass grafting successfully. Intravenous ultrasonography (IVUS) was effective for detecting and assessing the compression...
