Abnormalities of the hallux skin and nail in the course of very rare arteriovenous malformation.

Arteriovenous malformations (AVMs) are usually found in the pelvic area and the brain. These vascular anomalies are rarely reported in the toes. AVMs in the toes may be asymptomatic, but can also cause atypical symptoms.

The influences of selected clotting and fibrinolysis factors on survival of patients with kidney tumors - a prospective study.

Introduction: Multiple studies suggest that cancer leads to activation of clotting and fibrinolysis pathways, elevating the risk of thromboembolic events. Kidney cancer is often complicated by clotting disorders. In this study, we hypothesized that preoperative clotting and fibrinolysis parameters are altered in healthy volunteers and kidney tumor patients.

Von Willebrand Factor and ADAMTS13 as Predictors of Adverse Outcomes in Patients With Nonvalvular Atrial Fibrillation.

Background: Von Willebrand factor (VWF) elevation correlates with the left atrial blood stasis in nonvalvular atrial fibrillation (NVAF). However, the long-term impact of elevated VWF in patients with NVAF is not well established.

Methods: To assess the impact of VWF and a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 (ADAMTS13) in conjunction with echocardiographic measures of left atrium blood stasis on clinical outcomes, 414 NVAF prospectively recruited (October 4, 2007, to April 27, 2009) patients were followed for 3 years.

Analysis of peripheral nerve and autonomic nervous system function and the stage of microangiopathy in patients with secondary Raynaud's phenomenon in the course of connective tissue diseases.

Background: The pathogenesis of secondary Raynaud's phenomenon (SRP) associated with connective tissue diseases (CTD) is not entirely understood. Nervous system dysfunction and microangiopathy are considered to be causes of this pathology.

Objectives: Peripheral and autonomic nervous system function, the stage of microangiopathy, and the relationships between these in patients with SRP were analyzed.

Platelet-predominate gene expression and reticulated platelets in nonvalvular atrial fibrillation: Effect of pulmonary veins isolation.

Introduction: Reticulated platelet (RP) content is increased in nonvalvular atrial fibrillation (NVAF). The purpose of this study was to determine if platelet content, morphology, and RP proportion are modulated by platelet genes.

Methods And Results: Expression of six platelet-predominate genes impacting platelet formation and release, platelet count, and RP content was assessed in NVAF patients before and 3-4 months after pulmonary veins isolation (PVI) and compared to normal sinus rhythm (NSR) controls.

Role of Platelets in Thromboembolism in Patients with Atrial Fibrillation.

Thromboembolic complications of atrial fibrillation (AF) are a major cause of morbidity and mortality but the mechanism of its process remain poorly understood. There are many as yet unanswered questions surrounding the increased thrombotic tendency in AF. One of the crucial questions is what determines the fact that a thrombus remains in the left atrium in situ in some patients, while in others it breaks off and leads to embolic complications.

Prognostic value of tissue factor in patients with abdominal aortic and iliac arterial aneurysms - preliminary study.

Introduction: The decision on the time and choice of strategy of treatment of abdominal aortic aneurysm must be especially carefully balanced. The aim of the study was to evaluate the tissue factor (TF) plasma level as a potential factor useful in anticipation of abdominal aortic aneurysm and/or iliac arterial aneurysm via comparison of plasma TF level in patients with ruptured and non-ruptured aneurysms.

Material And Methods: The study included 33 patients with aneurysm (17 operated on electively because of non-ruptured aneurysm and 16 operated on emergently due to ruptured aneurysm), 33 claudicant patients with atherosclerosis of the abdominal aorta and iliac arteries with normal diameter of arteries, and 30 healthy controls.

Thromboembolism associated with atrial fibrillation as a cause of limb and organ ischemia.

Atrial fibrillation (AF) is associated with a high risk of thromboembolic episodes. Stroke is the most common embolic complication of AF. Consequently, the majority of the conclusions regarding the association between AF and embolism are based on clinical studies of patients with ischemic stroke.

Clinical characteristics and long-term follow-up of patients with renal vein thrombosis.

Background: To determine whether treatment guidelines for patients with lower-extremity venous thrombosis (DVT) could be applied to patients with renal vein thrombosis (RVT). The rates of recurrent venous thrombosis and survival for patients with these 2 diseases were compared.

Study Design: Inception cohort of individuals was identified with their first lifetime incident of RVT.

[The role of platelet glycoprotein receptors and their ligands: fibrinogen and von Willebrand factor in arterial thrombosis].

The arterial platelet thrombus contribute to development of thrombotic complications of atherosclerosis: acute coronary syndrome, thrombotic strokes and exacerbations of peripheral arterial occlusive disease. Platelet adhesion and aggregation is mediated by interaction between platelet glycoprotein receptors GPI b/IX GPII b/III a and their ligands-adhesive proteins: von Willebrand factor (vWF) and/or fibrinogen. Pharmacological blockade of interaction between glycoproteins receptor and their ligands may offer an effective prevention of thrombotic complications.
