Dr. Marc Rodger conducted a 12-year study showing that daily injections of blood thinners to prevent miscarriages don't work. We see Dr. Rodger in his office. Wearing a white hospital coat, he is looking at the camera. He wears rimless glasses and is smiling through slightly clenched lips. His brown hair is beginning to recede at the front and he sports a light beard and goatee with just a few touches of grey. He wears an open expression.

A Canadian researcher takes the road less travelled and prevails


Sometimes, you have to go against the flow. It can hurt and it takes courage, but sometimes–not always, mind you–everything really does work out for the better.

Dr. Marc Rodger knows the drill. He is a senior scientist at the Ottawa Hospital Research Institute who heads up the Thrombosis Program of the Ottawa Hospital.

For the last 12 years, Dr. Rodger and his research team took the road less travelled, carrying out a study of blood clots and pregnant women–292 women in 36 countries in five countries.

Ignoring resistance from various and sundry corners and bucking conventional wisdom, Dr. Rodger and his team proved conclusively that all that was thought to be true in the treatment of pregnant women and blood clots just wasn’t so.

Bottom line: Pregnant women need no longer give themselves painful daily injections of the anticoagulant low molecular weight heparin (LMWH) to prevent complications caused by placental blood clots.

The finding was good enough for The Lancet, the weekly peer-reviewed general medical journal that has been described as one of the most prestigious medical journals in the world. It published the results in July.

Dr. Rodger didn’t stop there. The study led to something else: the creation of a network called CanVECTOR, of which Dr. Rodger is co-director.

CanVECTOR aims to advance and co-ordinate research in diagnosis and improving quality of life of life and management of blood clots of the legs, lungs and heart both in Canada and globally, conditions that affect 500,000 Canadians and Americans every year.

Dr. Rodger spoke to RCI by phone from his office in Ottawa.

Note: By submitting your comments, you acknowledge that Radio Canada International has the right to reproduce, broadcast and publicize those comments or any part thereof in any manner whatsoever. Radio Canada International does not endorse any of the views posted. Your comments will be pre-moderated and published if they meet netiquette guidelines.

Netiquette »

When you express your personal opinion in an online forum, you must be as courteous as if you were speaking with someone face-to-face. Insults and personal attacks will not be tolerated. To disagree with an opinion, an idea or an event is one thing, but to show disrespect for other people is quite another. Great minds don’t always think alike—and that’s precisely what makes online dialogue so interesting and valuable.

Netiquette is the set of rules of conduct governing how you should behave when communicating via the Internet. Before you post a message to a blog or forum, it’s important to read and understand these rules. Otherwise, you may be banned from posting.

  1. RCInet.ca’s online forums are not anonymous. Users must register, and give their full name and place of residence, which are displayed alongside each of their comments. RCInet.ca reserves the right not to publish comments if there is any doubt as to the identity of their author.
  2. Assuming the identity of another person with intent to mislead or cause harm is a serious infraction that may result in the offender being banned.
  3. RCInet.ca’s online forums are open to everyone, without regard to age, ethnic origin, religion, gender or sexual orientation.
  4. Comments that are defamatory, hateful, racist, xenophobic, sexist, or that disparage an ethnic origin, religious affiliation or age group will not be published.
  5. In online speak, writing in ALL CAPS is considered yelling, and may be interpreted as aggressive behaviour, which is unpleasant for the people reading. Any message containing one or more words in all caps (except for initialisms and acronyms) will be rejected, as will any message containing one or more words in bold, italic or underlined characters.
  6. Use of vulgar, obscene or objectionable language is prohibited. Forums are public places and your comments could offend some users. People who use inappropriate language will be banned.
  7. Mutual respect is essential among users. Insulting, threatening or harassing another user is prohibited. You can express your disagreement with an idea without attacking anyone.
  8. Exchanging arguments and opposing views is a key component of healthy debate, but it should not turn into a dialogue or private discussion between two users who address each other without regard for the other participants. Messages of this type will not be posted.
  9. Radio Canada International publishes contents in five languages. The language used in the forums has to be the same as the contents we publish. The usage of other languages, with the exception of some words, is forbidden. Messages that are off-topic will not be published.
  10. Making repetitive posts disrupts the flow of discussions and will not be tolerated.
  11. Adding images or any other type of file to comments is forbidden. Including hyperlinks to other websites is allowed, as long as they comply with netiquette. Radio Canada International  is in no way responsible for the content of such sites, however.
  12. Copying and pasting text written by someone else, even if you credit the author, is unacceptable if that text makes up the majority of your comment.
  13. Posting any type of advertising or call to action, in any form, to Radio Canada International  forums is prohibited.
  14. All comments and other types of content are moderated before publication. Radio Canada International  reserves the right to refuse any comment for publication.
  15. Radio Canada International  reserves the right to close a forum at any time, without notice.
  16. Radio Canada International  reserves the right to amend this code of conduct (netiquette) at any time, without notice.
  17. By participating in its online forums, you allow Radio Canada International to publish your comments on the web for an indefinite time. This also implies that these messages will be indexed by Internet search engines.
  18. Radio Canada International has no obligation to remove your messages from the web if one day you request it. We invite you to carefully consider your comments and the consequences of their posting.
