Background: Pregnant women with pathological conditions requiring a neurosurgical intervention pose a unique therapeutic challenge. Changes in normal physiology add to the complexity of patient management. We describe our experience in treating various neurosurgical diseases in parturient women.
Methods: Thirty-four pregnant and early postpartum women were treated at our center between 2003 and 2010. The general guideline used in these patients (now deserving re-evaluation based on the presented data) was to postpone surgery until the patient reached term (weeks 34-38 of gestation) unless there was evidence of a life- or function-threatening condition, in which case surgery was promptly performed.
Results: Sixteen patients underwent neurosurgical intervention during pregnancy between 11 to 34 weeks of gestation (7 tumor, 3 vascular, 2 VP shunt, 2 spinal, 2 trauma). Thirteen women underwent a neurosurgical procedure after delivery (12 tumor, 1 spine), and 5 women were treated conservatively (2 vascular lesions, 3 trauma). Three patients underwent abortions (one spontaneous and two elective). The other 31 women delivered at 30-42 weeks' gestation. Of 12 patients whose definitive neurosurgical procedure was initially delayed, 5 were not able to complete their pregnancy naturally. Of 21 patients that underwent a cesarean section (CS), 3 were performed urgently. Although two pairs of twins and two singletons had an initial low Apgar score (<7), the outcome for all the neonates was good. Neurosurgical outcome was satisfactory.
Conclusions: Our experience demonstrates the safety of neurosurgical intervention and anesthesia during pregnancy. Delaying intervention often resulted in maternal deterioration and urgent intervention. Thus, pregnancy by itself should not be considered a major contraindication for performing a neurosurgical procedure, which should be considered early rather than late in most patients.
