Ans:A. Potter facies.
Potter sequence
It is a constellation of findings demonstrated postnatally as a consequence of severe, prolonged oligohydramnios in utero.
It consists of :
- pulmonary hypoplasia: often severe and incompatible with life
- growth restriction (IUGR)
- abnormal facies (Potter facies)
- low set ears
- flattened nose
- wrinkled skin
- micrognathia
- prominent infraorbital folds
- widely seperated eyes with epicanthic folds
- limb abnormalities: including club feet and contractures
Pathology
Although originally associated with renal causes of olighydramnios, the Potter sequence may be seen with severe oligohydramnios of essentially any cause.
Common aetiologies include:
- fetal renal insufficiency
- bilateral renal agenesis: traditionally known as the classic Potter syndrome
- autosomal recessive polycystic kidney disease
- posterior urethral valves, and other causes of antenatal renal tract obstruction
- premature rupture of membranes (PROM)
- twin-twin transfusion
