PEDICLE ARTERY SIGN
( AN OVERVIEW)
ADVANCED USG LOUNGE

2. PEDICLE
ARTERY SIGN
Feeding artery
appreciated in the pedicle
of the intracavitary
Endometrial lesions on
color doppler sonography
is called as pedicle artery
sign.
Positive pedicle artery
helps to identify
endometrial polyp s and
differentiate them from
other lesions like
subendometrial fibroid .
This sign can negate the
need for
sonohysterography
to demonstrate the
endometrial polyp .
ECHOGENIC
LESION IN ENDOMETRIAL
CAVITY WITH POSITIVE PEDICLE ARTERY SIGN
SUGGESTIVE OF ENDOMETRIAL POLYP

3. PEDICLE ARTERY SIGN
•COLOR DOPPLER USED
•SOLITARY WELL
FORMED ARTERY
ENTERS THE PEDICLE
OF ECHOGENIC FOCUS
IN THE ENDOMETRIAL
CAVITY.

4. USG APPEARANCE SYMPTOMS
 May appear as nonspecific
echogenic thickening.
 Round echogenic mass in
endometrial cavity.
 Better appreciated with
flluid in endometrial cavity.
 Broad based ( short stalk)
 Pedunculated ( long stalk)
 Postive pedicle artery sign
on color doppler.
 May be asymptomatic
 May cause uterine
bleeding
( intermenstrual bleed/
menometrorrhagia)
