Examination: Doppler ultrasonography
Changes seen on ultrasound:
(1) regular and smooth fiber structure
(2) localized widening with hypoechoic areas and/or irregular structures
(3) neovascular areas with increased vascular flow
Hypoechoic Areas and Structural Irregularities
Neovascularities and Increased Blood Flow
Neovascularization can also be classified by blood flow.
Blood Vessels and Flow
1 or 2 (low blood flow)
many (strong blood flow)
Administration of sclerosing therapy reduced pain but did not cause resolution of the changes seen on ultrasound.
