DVT and recurrent pilondial disease

Hi Everyone ,this question doesnt exactly concern me ,but it does a friend who has been getting these nasty blighters almost weekly ,for over a year or more ,i really cant understand the delay for an operation on it .She has also had 2 DVTs in her leg in the last year or so ,one causing a P.E. ,would this be the reason for the delay and what is her prognosis ,will the surgeons risk it or will she have to live with it for ever.She really doesnt like to talk about it but i am worried as i read that an untreated P.A can cause sepsis and possibly death ,so i am concerned because she is virtually housebound with 2 children and divorced .
