There is an incraesing trend to recommend longterm treatment to patients who have had a spontaneous DVT or PE as the risk of a recurence is approximately 3 to 5% per annum, with a 10 year risk of approximately 40%. Therefore if the patient has a low risk of bleeding consider longterm treatment after a single spontaneous event.
