Yes you can convert PDV document into word format provided you have got adobe reader 10 and also the pdf file intending to be converted should not be protected with any password by the originator or creator. 

1st open any pdf document in adobe reader 10 and then go to files - create pdf online 

then on the right side of the document an extension will be opened called export pdf files where you can select desired pdf file intended to be converted and start the conversion.
