Marc A. Rodger,M. T. Betancourt,M. T. Betancourt,Peter Clark,Pelle G. Lindqvist,Donna Dizon-Townson,Joanne M Said,Joanne M Said,Uri Seligsohn,Marc Carrier,Marc Carrier,Ophira Salomon,Ian A. Greer +12 more
TL;DR: The results of their systematic review and meta-analysis of prospective cohort studies that estimated the association of maternal factor V Leiden and prothrombin gene mutation carrier status and placenta-mediated pregnancy complications are reported.
Journal ArticleDOI
Risk of post-thrombotic syndrome after subtherapeutic warfarin anticoagulation for a first unprovoked deep vein thrombosis: results from the REVERSE study.
R S Chitsike,Marc A. Rodger,Michael J. Kovacs,M. T. Betancourt,P. S. Wells,David Anderson,Isabelle Chagnon,G. Le Gal,Susan Solymoss,Mark Crowther,Arnaud Perrier,Richard H. White,Linda M. Vickars,Tim Ramsay,Susan R. Kahn,Susan R. Kahn +15 more
TL;DR: A large number of the patients diagnosed with post‐thrombotic syndrome have a history of atypical clotting problems and the prognosis is poor, particularly for those who have had previous heart attacks.
Journal ArticleDOI

Jean-Philippe Galanaud,Christina Holcroft,Marc A. Rodger,Marc A. Rodger,Michael J. Kovacs,M. T. Betancourt,M. T. Betancourt,P. S. Wells,P. S. Wells,David Anderson,Isabelle Chagnon,G. Le Gal,G.

TL;DR: Signs and symptoms of post‐thrombotic syndrome are non‐specific, and could result from concomitant primary venous insufficiency rather than DVT, which could bias evaluation of PTS.
Journal ArticleDOI
Comparison of the Villalta post-thrombotic syndrome score in the ipsilateral vs. Contralateral leg after a first unprovoked deep vein thrombosis
J-P Galanaud,Christina Holcroft,Marc A. Rodger,Marc A. Rodger,Michael J. Kovacs,M. T. Betancourt,M. T. Betancourt,P. S. Wells,P. S. Wells,David Anderson,Isabelle Chagnon,G. Le Gal,Susan Solymoss,Susan Solymoss,Mark Crowther,Arnaud Perrier,Richard H. White,Linda M. Vickars,Tim Ramsay,Tim Ramsay,Susan R. Kahn,Susan R. Kahn +21 more
TL;DR: The Villalta scale is a clinical measure that incorporates venous symptoms and signs in the leg ipsilateral to a DVT that are not specific for PTS and their prevalence and relevance in the contralateral leg have not previously been studied.
