[The perinatal risk factors of periventricular leukomalacia (PVL) in premature infants].
Periventricular leukomalacia (PVL) has recently been recognized as an important risk factor in neurological impairment of the premature infant. We studied 29 PVL cases concerning perinatal risk factors retrospectively comparing them with a non-PVL matched control group. Variable decelerations were more frequently observed with statistical significance in the PVL group in the intrapartum period. There was no significant difference between the two groups in the appearance of late deceleration. A lower incidence of RDS, a higher incidence of low Apgar score, a longer period of ventilation and oxygen inhalation and a more persistent presence of apneic spells were documented in the PVL group with statistical significance. Our study suggests the significance of variable deceleration as a risk factor in the occurrence of PVL in premature infants as well as other previously documented risk factors.
