Ann Vasc Dis 2017 Dec;10(4):364-370

The Vein & Vascular Center, Aisei Hospital, Tokyo, Japan.

In our varicose vein center, on a trial basis, among the patients with asymptomatic calf deep vein thrombosis (CDVT) we carefully selected the patients for varicose vein surgery using the requirements as follows; 1) the patients had varicose veins with incompetent saphenous veins, 2) sequential examination including DUS confirmed stability and clinical insignificance of asymptomatic CDVT, 3) the patients do not have any risk factors for DVT such as a coagulation profile disorder (antithrombin deficiency, protein C deficiency, protein S deficiency, or antiphospholipid syndrome) or malignancies, 4) surgery is possible under local anesthesia alone, and 5) the patients can understand the concept of asymptomatic CDVT and undergo the surgery on their own will and informed consent. The patients who fulfilled these conditions underwent the varicose vein surgery. Twenty-eight patients with 30 limbs with varicose veins had asymptomatic CDVT, found by preoperative duplex ultrasonography (DUS). Read More

Björn Dahlbäck

Semin Thromb Hemost 2018 Mar 13;44(2):176-184. Epub 2017 Sep 13.

Department of Translational Medicine, Lund University, Malmö, Sweden.

Protein S is a vitamin K-dependent plasma glycoprotein circulating in plasma at a concentration of around 350 nM. Approximately 60% of protein S in human plasma is bound to the complement regulatory protein C4b-binding protein (C4BP) in a high-affinity, high-molecular-weight complex. Protein S in plasma has multiple anticoagulant properties and heterozygous protein S deficiency is associated with increased risk of venous thrombosis. Read More

Thrombogenesis in Thrombophilic Pregnancy: Evaluation of Low-Molecular-Weight Heparin Prophylaxis.

Acta Haematol 2017 6;137(4):201-206. Epub 2017 May 6.

Institute for Maternal and Child Health, IRCCS "Burlo Garofolo," Trieste, Italy.

The aim of this study is to investigate thrombogenesis and the hypercoagulable changes in pregnant women affected by thrombophilia who received low-molecular-weight heparin (LWMH) prophylaxis. We included 21 pregnant women affected by thrombophilia treated with LWMH and 20 nontreated normal pregnant women as the control group. The sample group of thrombophilic pregnant women included different conditions (factor V Leiden mutation, protein C deficiency, protein S deficiency, antiphospholipid antibodies syndrome, and combined defects).
