Flashcards in 2. Potter sequence (syndrome) Deck (11):
1

Oligohydramnios is a

condition in pregnancy charactirized by deficiency of amniotic fluid

2

Potter sequence ( syndrome ) is the

atypicaλ physical apperance of a fetus or neonate due to oligohydramnios experienced in the uterus

3

mechanism and manifestations

oligohydramnios --> compression of developing fetus ( byt the uterus ) --> limb deformites, facial anomalies , pulmonary hypoplasia

4

presentation

1. limb deformites,
2.facial anomalies ,(low set ears,retrognathia, flattened nose )
3.pulmonary hypoplasia

5

facial anomalies

low set ears,retrognathia, flattened nose

6

pulmonary hypoplasia mechanism

compression of chest and LACK of aspiration of amniotic fluid into fetal lung

7

the fetal urine and lungs

the fetal urine is critical to proper development of the lungs by aiding in the expansion of the airways - alveoli

8

cause od death

pulmonary hypoplasia

9

cause of Potte sequence ( syndrome )

1. ARPKD
2. Obstructive uropathy (posterior urethral valves)
3. bilateral renal agenesis
4. chronic placental isuficiency

10

Potter sequence ( syndrome) mnemonic

POTTER sequence associated with:
Pulmonary hypoplasia
Oligohydramnios (trigger)
Twisted face
Twisted skin
Extremity defects
Renal failure (in utero)

11

• A newborn is found to have bilateral renal agenesis, which leads to the Potter sequence (syndrome). What else causes this sequence to occur?

Autosomal recessive polycystic kidney disease (ARPKD), obstructive uropathy (e.g., posterior urethral valves)
