J. Jurgens et J. Woll, Theoretical thoughts about the sonographic diagnosis of real cordknot based on experimental evidence, Z GEBU NEON, 203(2), 1999, pp. 73-76
Modern sonographic technique allows the detection of cord complication as n
eck cord entanglement. Far more difficult is the detection of a real cord k
not. This article describes a theoretical model for detection of a cord kno
t and proves it in an in-vitro model.
