Methodologic problems in this study included selection bias for venography, the use of non-filling of veins or venous segments for diagnosis, and reliance on an alternative (and unproven) gold standard [2] when venography was unsatisfactory. Furthermore, the cited European study [3] used different instrumentation and a different method of interpretation than the standard IPG technique. In fact, the authors' data suggest that 90% of their patients could have been ...References1. Anderson DR, Lensing AW, Wells PS, Levine MN, Weitz JI, Hirsh J.

The differences are emphasized. Various aspects of thrombosis in pregnancy have been well summarized in several secondary sources, including the version of this chapter in the third edition of this volume and in original papers in the clinical literature.9–13 I have consulted these secondary sources and journal articles while composing the present chapter, and I refer to both types of sources. 1 August 1993Volume 119, Issue 3Page: 246-247KeywordsProspective studiesRetrospective studiesVeins Issue Published: 1 August 1993 CopyrightCopyright © 1993 by American College of Physicians.
