Give 4 transient risk factors for DVT

Is treatment indicated for a below-knee DVT?

- It is not known whether a below-knee DVT confers increased risk of PE; it is certainly a common incidental finding in otherwise well individuals.

- If local symptoms are thought to be due to the DVT, offer treatment. If not, consider repeat scanning in one week to see if the clot has extended proximally.


Which patients with DVT should undergo investigation for an underlying cause?

Those aged >55 years with unprovoked DVT, and those with recurrent unprovoked DVT or DVT at an unusual site.
