BACKGROUND: Whether patients on testosterone replacement therapy undergoing noncardiac surgery have an increased risk of postoperative in-hospital mortality and cardiovascular events remains unknown. We therefore sought to identify the impact of testosterone replacement on the incidence of a composite of postoperative in-hospital mortality and cardiovascular events in men undergoing noncardiac surgery. METHODS: Data from male American Society of Anesthesiologists I through IV patients 40 yr or older who underwent noncardiac surgery between May 2005 and December 2015 at the Cleveland Clinic (Cleveland, Ohio) main campus were included...

Venous thromboembolism (VTE) is a potentially life-threatening condition that includes both deep vein thrombosis (DVT) and pulmonary embolism. We sought to improve detection and reporting of children with a new diagnosis of VTE by applying natural language processing (NLP) tools to radiologists' reports. We validated an NLP tool, Reveal NLP (Health Fidelity Inc, San Mateo, CA) and inference rules engine's performance in identifying reports with deep venous thrombosis using a curated set of ultrasound reports...

In this case report, we describe an unusual episode of bilateral submassive pulmonary embolism (PE) caused by a popliteal vein aneurysm (PVA). The development of PE stems from many risk factors including obesity (BMI³ 30 kg/m2), hypertension, cigarette smoking (greater than 25 cigarettes per day), increasing age, surgery, immobility, malignancy, and inherited thrombophilia. A PVA is a rare but significant cause of PE. A 28-year-old male presented to the emergency department with progressive shortness of breath...

Paradoxical embolism is a known complication with intra-cardiac shunts. It should be considered in the differential as the pathophysiologic mechanism of simultaneous thromboembolism in the venous and systemic vasculature. We present a case of simultaneous deep venous thrombosis, pulmonary embolism and myocardial infarction in the presence of a confirmed patent foramen ovale on echocardiography. Thrombolytic therapy was administered. Subsequent concerns of intracranial hemorrhage on imaging of the brain complicated the management and added to the challenge of co-managing the clot burden in our patient...

The post-thrombotic syndrome (PTS) is the most common long-term complication of pediatric deep venous thrombosis (DVT). It is a burdensome condition that can lead to severe disability and poor quality-of-life of affected children. Although its pathophysiology remains poorly understood, it is thought to be the result of chronic venous hypertension. Recent studies have shown that the inflammatory response associated with an acute DVT likely plays a key role in the development of PTS. The Manco-Johnson Instrument and the modified Villalta Scale are the most widely used instruments for the diagnosis of pediatric PTS...

Patients with acute limb ischemia, deep venous thrombosis and pulmonary artery embolism may be treated with warfarin. The dose-response interaction of warfarin is associated with numerous factors, depending on which an uncommon life-threatening bleeding may occur. The present case study reported on a patient with acute limb ischemia and a history of warfarin-induced bleeding ten years previously and who again developed life threatening bleeding associated with warfarin treatment and received vascular surgery...

BACKGROUND: Critically ill patients are considered a high-risk group for developing venous thromboembolism (VTE). Due to their impaired cardiopulmonary reserve, these VTEs may result in significant morbidity and mortality. In this study, we compared two types of low molecular weight heparin, enoxaparin, and bemiparin, as regards to their efficacy and safety in VTE prevention among Intensive Care Unit (ICU) patients. METHODS: This study was a prospective, randomized trial of 100 critically ill patients who are at high risk for developing VTE were included in this study and assigned to receive subcutaneous injections of either 3500 international units (IU) anti-factor Xa of bemiparin sodium or 40 mg of enoxaparin given once a day and patient were followed for 60 days after initiation of anticoagulant therapy for the development of documented deep venous thrombosis (DVT) using bilateral lower limb venous duplex, documented pulmonary embolism using computed tomography pulmonary angiography, and complications related to injectant anticoagulant...

BACKGROUND: Osteonecrosis of the femoral head (ONFH) often affects young active adults and leads to destruction of the hip joint and disabling arthritis. Several procedures have been developed to arrest the progress of osteonecrosis and postpone the procedure of total hip replacement especially in young patients. The aim of this multicenter study was to analyze the results of the use of the vascularized iliac bone flap transfer for management of ONFH. METHODS: From January 1985 to December 2012, a total of 2190 patients (2690 hips) with the mean age of 43...

Soma Mohammed, Emmanuel J Favaloro
Activated protein C resistance (APCR) describes a hemostatic disorder characterized by a poor anticoagulant response to activated protein C (APC). This results in an increased risk of venous thrombosis, including deep vein thrombosis and pulmonary embolism. Protein C is a natural anticoagulant that is synthesized in the liver and is activated to APC via proteolysis. APC then degrades Factors Va and VIIIa. APCR describes the reduced inability of APC to cleave Factors Va and VIIIa, which therefore promotes increased thrombin generation and potentially leads to a prothrombotic state...

Venous thromboembolism, usually entailing deep vein thrombosis, pulmonary embolism, or both, is a complex and multifactorial disorder, in which a number of putative conditions interplay and finally contribute to propel the individual risk over a certain degree, so ultimately culminating in the development of venous occlusive disorders. Thrombophilia is commonly defined as a propensity to develop venous thromboembolism on the basis of an underlying hypercoagulable state attributable to inherited or acquired disorders of blood coagulation or fibrinolysis...

Inferior vena cava (IVC) anomalies were rare and usually asymptomatic. Among these, anomalies absence of infra-renal IVC is the rarest anomaly. Absence of infra-renal IVC may present with symptoms of venous insufficiency and idiopathic deep vein thrombosis. Contrast enhanced CT and MRI abdomen play crucial role in diagnosing these anomalies. These patients can be managed conservatively or by venous bypass. Identification of these anomalies is important to avoid surgeries for varicose veins.

The hemodynamics in flexible deep veins valves is modelled by means of discrete multi-physics and an agglomeration algorithm is implemented to account for blood accrual in the flow. Computer simulations of a number of valves typologies are carried out. The results show that the rigidity and the length of the valve leaflets play a crucial role on both mechanical stress and stagnation in the flow. Rigid and short membranes may be inefficient in preventing blood reflux, but reduce the volume of stagnant blood potentially lowering the chances of thrombosis...
