DVT

Introduction:

Bedside ultrasound has been shown to correlate very well with formal duplex sonography in detecting deep vein thrombosis (DVT). A limited, two-point compression technique is generally employed which verifies flow and compressibility in the common femoral and popliteal veins.

Focused Questions:

  1. Is there flow in the vein?
  2. Is the vein compressible?

Required Views:

1. Femoral vein

Notes
  • Visualize the femoral vein and femoral artery proximally, just distal to the inguinal ligament
  • Use color Doppler to check for flow in the vein (vein is usually medial to artery)
  • Check that the vein compresses totally
  • Often a split screen is used to show the vessels without (Left screen) and with compression (Right screen)

2. Popliteal vein

Notes
  • Visualize the popliteal vein and artery in the popliteal fossa
  • Use color Doppler to check for flow in the vein (vein is usually superfical to artery)
  • Check that the vein compresses totally
  • Often a split screen is used to show the vessels without (Left screen) and with compression (Right screen)
