									      The Pelvic Scan:
 Early pregnancy problems
Gynaecological abnormalities
        Normal pelvic anatomy
•   Anatomy of uterus and ovaries
•   Arterial blood supply
•   Venous blood supply
•   Neural supply
Gynaecological scan indications
•   Pelvic pain
•   Pelvic mass
•   Irregular/ heavy vaginal bleeding
•   Post menopausal vaginal bleeding
•   Infertility
•   Endocrine symptoms/ signs
•   Recurrent miscarriage
• Sagittal image uterus and bladder
  – Length of endometrium and cervix
  – Measure length uterus +/- ET in AP
  – Check for fluid in POD
• Transverse image bladder and cervix
• Transverse image bladder and uterus at widest
  – Image whole uterus as move cephalad
  – Measure ET in AP
  – Measure uterus width and AP
• Transverse to top of uterus
• Transverse image broad ligament
• Move to Right/Left
  – Check no tubal dilatation
  – Visualise ovary
  – Move caudally if unable to see
• Split screen and measure ovarian volume
• Cyst?
  – Measure volume
  – Septations, papillary lesions, solid areas, low level
    internal echoes
  – Check mobility with valsalva or hand on abdomen
  – Check for ascites
  – Torsion?

    Early pregnancy scan indications
•   Dating
•   Bleeding
•   Pain
•   Previous ectopic/ miscarriage/ molar
Complete miscarriage

                Bleeding and
                which are
Missed miscarriage

               Spotting only
               Expected to
               be 6-12
               weeks by
               Fetal pole
Missed Miscarriage
          Other miscarriages
• Anembryonic pregnancy
  – Spotting or nil
  – Gestational sac, MSD >2cm
  – No fetal pole
• Incomplete miscarriage
  – Bleeding and cramps
  – RPOC
  – Doppler to diagnose
• Threatened miscarriage
  – Bleeding +/- pain
  – Viable pregnancy
            Ectopic pregnancy
• Pregnancy outside the uterine corpus
  –   Ampulla
  –   Cornu
  –   Ovary
  –   Abdominal
• Life- threatening intra-abdominal bleeding
• Symptoms and signs
  – Spotting, pain- usually one side, fainting, shouler-tip
• URGENT referral on USS diagnosis
• High index of suspicion if
  – previous ectopic
  – IUD
  – infertility
Tubal Ectopic Pregnancy
              USS findings
• Empty uterus
• Adnexal mass
  – +/- FHR
  – Ring of blood flow on doppler
  – Tenderness on probe pressure over mass
• Free fluid especially POD
• TV scan ideally if available
Ectopic with FHR
    Hydatidiform molar pregnancy
•   Abnormal placental development
•   Usually no recognisable fetus
•   ‘Snowstorm’ appearance on USS
•   Exaggerated symptoms of pregnancy
    – Hyperemesis
    – Thyroid hormone abnormality
    – Large theca-lutein cysts
• Rx is ERPOC and CXR
• Can recur and rarely in malignant form
