This subgroup lacks standard clinical practice guidelines due to differing viewpoints on the etiopathogenesis, natural history, treatment and outcome. Most originate in the calf and resolve spontaneously. Detection also depends on the diagnostic modality used with invasive methods like venography yielding a higher incidence. It is seen more often in patients with transient risk factors (recent surgery, recent plaster immobilization, recent travel). Thrombus propagation/ extension can occur in 25%- 36% with symptomatic PE in 6-36%. Recurrence occurs in 4-29 % , chronic venous insufficiency( post thrombotic syndrome) can occur in 4- 23 %. The overall event rate (death, PE, extension, bleeding) is about 5% which can be further lowered with treatment ER -
