Author: Dr. Aaron Lessen

Educational Pearls:

  • New guidelines about treating small clots in the leg and lungs published by the American Academy of Chest Physicians.
  • In a patient with a DVT in the calf, without cancer or long term immobility concerns, there is a 15% chance of the clot moving up the leg or into the lungs. As an alternative to anticoagulation the patient may get an ultrasound every 3-4 days for 2 weeks.
  • A patient with a subsegmental PE – small, peripheral PE –that may not cause major problems to the lungs if there is not a clot in proximal leg, a physician may consider not using anticoagulation, but rather close follow up.
