Journal ArticleDOI

TL;DR: This open-label, randomised controlled trial aimed to examine whether additional treatment with catheter-directed thrombolysis using alteplase reduced development of post-thrombotic syndrome in patients with a high proximal DVT and low risk of bleeding.
Journal ArticleDOI
Blood platelet count and function are related to total and cardiovascular death in apparently healthy men.
TL;DR: The present study is the first to present conclusive, prospective evidence of an association between platelet concentration and aggregability and long-term incidence of fatal coronary heart disease in a population of apparently healthy middle-aged men.
Journal ArticleDOI
Post-thrombotic syndrome after catheter-directed thrombolysis for deep vein thrombosis (CaVenT): 5-year follow-up results of an open-label, randomised controlled trial
Ylva Haig,Tone Enden,Ole Jørgen Grøtta,Nils-Einar Kløw,Nils-Einar Kløw,Carl-Erik Slagsvold,Waleed Ghanima,Leiv Sandvik,Geir Hafsahl,Pål Andre Holme,Pål Andre Holme,Lars Olaf Holmen,Anne Mette Njaaastad,Gunnar Sandbæk,Gunnar Sandbæk,Per Morten Sandset,Per Morten Sandset +16 more
TL;DR: Catheter-directed thrombolysis resulted in a persistent and increased clinical benefit during follow-up for up to 5 years, supporting the use of additional catheter- directed throm bolysis in patients with extensive proximal DVT.
Journal ArticleDOI
Catheter-directed thrombolysis vs. anticoagulant therapy alone in deep vein thrombosis: results of an open randomized, controlled trial reporting on short-term patency.
Tone Enden,Nils-Einar Kløw,Nils-Einar Kløw,Leiv Sandvik,Leiv Sandvik,Carl-Erik Slagsvold,Waleed Ghanima,Geir Hafsahl,Pål Andre Holme,Lars Olaf Holmen,Anne Mette Njaastad,Gunnar Sandbæk,Per Morten Sandset,Per Morten Sandset +13 more
TL;DR: After 6’months, additional CDT increased iliofemoral patency from 36% to 64%.
Journal ArticleDOI

TL;DR: Bowel distension was inferior in MRI per OS compared to MRE, however, both methods diagnosed Crohn’s disease with a high diagnostic accuracy and reproducibility.
