Clinical meaning of incompetent perforators in the setting of post-thrombotic syndrome commentary
2015
In this issue of Phlebological Review Zolotukhin et al. [1] present the results of their study on recurrence of venous leg ulcers in post-thrombotic patients after endovenous laser ablation of incompetent lower leg perforators. They have found that not only the recurrence rate of these perforators was very high, but also that the procedure did not reduce the ulcer recurrence. This lack of clinical efficacy in terms of recurrence was different from the results of the well-known ESCHAR study [2]. In the ESCHAR study surgical ablation of incompetent superficial veins resulted in less frequent recurrences. From a hemodynamic and pathophysiological point of view a thermal ablation (such as laser…
Residual vein thrombosis and onset of post-thrombotic syndrome: Influence of the 4G/5G polymorphism of plasminogen activator inhibitor-1 gene
2013
Abstract Background Plasminogen activator inhibitor-1 (PAI-1) is the most important inhibitor of plasminogen activator. The functional 4G/5G polymorphism of the gene coding for PAI-1 may affect PAI-1 plasmatic activity, influencing the imbalance between coagulation and fibrinolysis cascades. In this prospective cohort analytic study, we investigated the role of this single nucleotide polymorphism in the persistence of thrombotic lesion and the occurrence of post-thrombotic syndrome. Patients/Methods In a group of 168 patients with post-surgical deep vein thrombosis of the legs, we analyzed the 4G/5G polymorphism in the promoter of PAI-1 gene and plasmatic PAI-1 activity. Enrolled patients w…
Thigh-length versus below-knee compression elastic stockings for prevention of the postthrombotic syndrome in patients with proximal-venous thrombosi…
2012
Abstract Although below-knee compression elastic stockings (CES) are effective for the prevention of the postthrombotic syndrome (PTS), a substantial number of patients with deep venous thrombosis still develop PTS. In the present open-label, randomized clinical trial, we compared thigh-length with below-knee CES for the prevention of PTS. A total of 267 patients with the first episode of proximal deep venous thrombosis were randomized to wear either thigh-length or below-knee CES for 2 years. After 3, 6, 12, 18, 24, and 36 months, they were assessed for PTS manifestations according to the Villalta scale. PTS developed in 44 (32.6%) of the 135 patients randomized to thigh-length CES and in …
