Non classical Potter’s sequence: a rare complication of chronic oligohydramnios

Abstract

Chronic oligohydramnios due to any cause can have grave foetal prognosis. One of the rare complications is Potter‘s sequence which occurs as a result of intrauterine mechanical compression of the foetus due to decreased liquor volume. This case report aims to give an insight into this rare complication. Classical Potter‘s sequence is due to renal cause whereas non classical, a still rarer variant of Potter‘s sequence is due to non renal cause. We describe a case of a lady at 38 weeks of gestational age with chronic oligohydramnios due to prolonged leaking per vaginum and severe intrauterine growth restriction. She delivered a congenitally malformed male baby with features of Potter‘s sequence. The renal abnormalities were conspicuously absent in our case, suggesting a diagnosis of non classical Potter sequence.
