Deep Vein Thrombosis

2015

Venous thromboembolism (VTE) comprises deep vein thrombosis (DVT) and pulmonary embolism (PE). DVT occurs at an incidence of 1/1,000 and risk factors include immobilization, hospitalization, surgery, thrombophilia and positive family history, cancer, pregnancy, and other hormonal effects. Commonly, clinical signs and symptoms for DVT are unreliable, especially in hospitalized patients, but the clinical assessment of the pretest probability, for example, with the Wells score, is an important component in the diagnostic algorithm, where compression ultrasound also plays a central role. Treatment of DVT aims to acutely prevent PE and short-term and long-term VTE recurrence and to avoid the lon…

Todavía unas palabras sobre las venas cefálica y basílica

1993

Ever since 1879, when Josef Hyrtl first formulated his thesis that the names of the cephalic and basilic veins, as applied to the arm veins, were of Arab origin, a dis­cussion began between philologists and historians of medicine as the former defen­ded the Greek source of such denominations whilst the latter shared the view of the Viennese anatomist. The author, after making a critical review of the -relevant works published hit­herto, unearthes a text drawn from a Persian manuscript dating back to the 15th century that, in his view, confirms the rigthness of the Viennese anatomist's thesis.

Tailoring Novel PTFE Surface Properties: Promoting Cell Adhesion and Antifouling Properties via a Wet Chemical Approach

2016

Many biomaterials used for tissue engineering applications lack cell-adhesiveness and, in addition, are prone to nonspecific adsorption of proteins. This is especially important for blood-contacting devices such as vascular grafts and valves where appropriate surface properties should inhibit the initial attachment of platelets and promote endothelial cell colonization. As a consequence, the long-term outcome of the implants would be improved and the need for anticoagulation therapy could be reduced or even abolished. Polytetrafluoroethylene (PTFE), a frequently used polymer for various medical applications, was wet-chemically activated and subsequently modified by grafting the endothelial …

Short- and long-term outcomes for the surgical treatment of acute pulmonary embolism

2018

AbstractObjectivesAcute pulmonary embolism can be a life-threatening condition with a high mortality. The treatment choice is a matter of debate. The early and late outcomes of patients treated with surgical pulmonary embolectomy for acute pulmonary embolism in a single center were analyzed.MethodsAll consecutive patients operated on for pulmonary embolism between January 2002 and March 2017 were reviewed. Patient demographics and pre- and postoperative clinical data were retrieved from our patient registry, and risk factors for in-hospital and long-term mortality were identified.ResultsIn total, 175 patients (mean age 59±3 years, 50% male) were operated on for acute pulmonary embolism. In-…

MitoKATP-channel opener protects against neuronal death in rat venous ischemia.

2005

OBJECTIVE: Mitochondrial adenosine triphosphate-dependent potassium (mitoK ATP ) channels are present in the brain, and several reports have shown their neuroprotective, preconditioning effect against an ischemic insult. The role of mitoK ATP channels in the penumbra area has not been studied thoroughly. In a model of venous ischemia, widespread penumbra-like low flow areas are created, which are susceptible to cortical spreading depression. Thus, we studied effects of mitoK ATP channels on infarct size in this model. METHODS: Male Wistar rats were subjected to two-vein occlusion by photochemical thrombosis of two adjacent cortical veins combined with KCI-induced cortical spreading depressi…

Portal vein thrombosis and Budd-Chiari syndrome as onset of Polycythaemia Vera.

Portal vein thrombosis and Budd-Chiari syndrome as onset of polycythemia vera

2013

Budd-Chiari syndrome may be defined as a heterogeneous group of vascular disorders characterized by obstruction of hepatic venous return to the level of hepatic venules, supra-hepatic veins, inferior vena cava or right atrium. The main cause of this syndrome is represented by myeloproliferative diseases and, in particular, by polycythemia vera. The latter may cause multiple splanchnic thrombosis, including portal vein thrombosis, particularly important for its clinical outcomes (ascites, collateral vessels genesis, etc.). We report 2 cases of a Budd-Chiari syndrome induced by polycythemia vera characterized by an abnormal clinical onset, both as regards subjects’ age (29 and 39 years old, r…

THE ASSOCIATION BETWEEN PROGRESSION OF POST-SURGICAL CALF VEIN THROMBOSIS AND 4G/5G POLYMORPHSM IN THE PROMOTER OF THE PLASMINOGEN ACTIVATOR INHIBITOR

The effect of human osteoblasts on proliferation and neo-vessel formation of human umbilical vein endothelial cells in a long-term 3D co-culture on p…

2008

Angiogenesis is a key element in early wound healing and is considered important for tissue regeneration and for directing inflammatory cells to the wound site. The improvement of vascularization by implementation of endothelial cells or angiogenic growth factors may represent a key solution for engineering bone constructs of large size. In this study, we describe a long-term culture environment that supports the survival, proliferation, and in vitro vasculogenesis of human umbilical vein endothelial cells (HUVEC). This condition can be achieved in a co-culture model of HUVEC and primary human osteoblasts (hOB) employing polyurethane scaffolds and platelet-rich plasma in a static microenvir…
