Sorry I don't know But there is a way to search for periodicals online. This works only if you have a library card, your library is online, and your library subscribes to these databases...
So right now I'm going on my library's homepage, click on Articles and Databases - select a database search engine I chose Gale InfoTrac OneFile because it has 76,810,559 articles updated as recently as November 21, 2008 - enter my card number - and then do a Basic keyword search for Thoracic Outlet Syndrome. I got 100 results and many of them are full text! They each list the title, author, publication, date and length of the article.

Now if you can do this and you can remember more about this article you can tweak the search options. I really hope you can access this!! If you can't please let me know and I can try to find it with your help using my library resources.

I think its great that you want to find it and share with your friends what its like to be in your shoes
