PEDICLE ARTERY SIGN( AN OVERVIEW)

ADVANCED USG LOUNGE

PEDICLE ARTERY

SIGNFeeding 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

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

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)
