Abstract
Prenatal artery occlusion is a relatively rare diagnosis, often under subclinical. Therefore, diagnostics often escape and so its exact incidence is unknown.
Diagnosis is often determined after delivery. Its closure mostly occurs idiopathically, but is also described in connection with the use of prostaglandin-inhibitors by the mother in the second and third trimesters of pregnancy.
During prenatal arterial occlusion, there is a significant overload and consequently failure of the right-sided heart sections, which can lead to intrauterine death of the fetus. Depending on the closure time, the speed of diagnosis, and the subsequent termination of pregnancy, it may appear under different clinical images after birth.
We present four patients with this diagnosis.
