BACKGROUND Portal vein thrombosis (PVT) is an infrequent clinical condition usually associated with multiple etiological factors and diseases. In some cases, PVT remains undiagnosed and is incidentally detected during routine examination for a known etiology. CASE REPORT Here, we present a rare case of portal vein thrombosis associated with acute cholecystitis in a 31-year-old man. CONCLUSI...

Portal vein thrombosis (PVT) is a potential complication of cirrhosis and can worsen outcomes after liver transplant (LT). Portal vein reconstruction-transjugular intrahepatic portosystemic shunt (PVR-TIPS) can restore flow through the portal vein (PV) and facilitate LT by avoiding complex vascular conduits. We present a case of transsplenic PVR-TIPS in the setting of complete PVT and splenic v...

INTRODUCTION The prevalence of portal vein thrombosis (PVT) in patients that have undergone liver transplantation (LT) is 9.7% (SD 4.5). The aim of our study was to determine the prevalence, assess the factors that are associated with PVT and clarify their association with prognosis in patients with liver cirrhosis (LC) and LT. AIMS AND METHODS From 2005 to 2014, laboratory, radiological and ...

Management of prosthetic valve thrombosis in pregnancy Tratamento da trombose da válvula protética na gravidez Dear Editor, We read with great interest the article by Cardoso et al. which was recently published in the Journal. 1 We thank the authors for the contribution of their report describing thrombolytic therapy (TT) with streptokinase (SK) in a pregnant patient with prosthetic valve throm...

BACKGROUND Recommendations for treatment of mechanical prosthetic heart valve thrombosis (PVT) include systemic thrombolysis and/or reoperation. Data on complications and outcome are limited. METHODS Clinical and echocardiographic findings of 17 patients with mechanical PVT were reviewed. Complications and outcome of surgery and/or thrombolysis were analysed. Prospective follow-up was obtaine...

Prosthetic valve thrombosis (PVT) is classically a cardiothoracic surgical emergency. Case series, however, report thrombolysis as first line management for PVT. A case of mitral PVT treated successfully with thrombolysis is described. Immediately after thrombolysis a trivial paraprosthetic leak noted on pretreatment transoesophageal echocardiography had increased significantly in severity. The...

This paper proposes a gate-delay model suitable for timing analysis that takes into consideration wideranging process–voltage–temperature (PVT) variations. The proposed model translates an outputcurrent fluctuation due to PVT variations into modifications of the output load and input waveform. After translation, any conventional model can compute delay taking into account PVT variations by usin...

PORTAL VEIN TlIROMBOSIS (PVT) or thrombosis of its tributaries has been a formidable surgical challenge in orthotopic hepatic transplantation (OHT). At one time, PVT was considered a relative contraindication for OHT. However, refinements of the technique to reconstruct the portal vein after thrombosis have included venous grafting procedures (1, 2). The technique of the venous "jump" graft fro...

This commentary focuses on novel findings by Clark et al. (2017) published in eNeuro, which show that dopamine D2 receptors (D2Rs) in the paraventricular nucleus of the thalamus (PVT) are involved in cocaine sensitization. We extend the discussion on how their findings contribute to our understanding of the role of the PVT in drug seeking by providing new insight on the role of the PVT in the r...

The paraventricular thalamic nucleus (PVT) is a midline nucleus with strong connections to cortical and subcortical brain regions such as the prefrontal cortex, amygdala, nucleus accumbens and hippocampus and receives strong projections from brain stem nuclei. Prepulse inhibition (PPI) is mediated and modulated by complex cortical and subcortical networks that are yet to be fully identified in ...
