[Do differences exist in the neurosurgical handling of intracranial lesions of pregnant patient? Outcomes of our experience and literature review]

OBJECTIVE

The main objective of our work is to revise our neurosurgical experience in pregnant patient and to carry out a revision of the related literature in order to optimize the neurosurgical handling of these kind of patients.

METHOD

Retrospective study between august 1993 and June 2010. We included patients who were pregnant at the time and who presented any trace of cranial neurosurgical or spinal disease.

RESULTS

The research includes the cases of 12 patients aged between 17 and 37 years old with an average age of 28.8 years old. The average gestation period was of 24.17 weeks, finding 50% of the patients within their third three-month period of pregnancy at the moment of diagnosis, 25% in their second three-month period and the remaining 25% in their first three-month period. The mean follow-up duration for this series was 84 months. 4 of them presented brain vascular lesions, 5 presented brain tumor lesions, 1 of them presented Chiari malformation, one lumbar disc herniation and 1 patient suffered from traumatic intracraneal hemorrhage. 8 of the 12 patients were subjected to neurosurgical procedures under general anesthetic, 2 for aneurysm embolizations and 2 for conservative treatments. Between the neurosurgical procedures 6 craniotomies were done, of wich 4 were to resection of the tumor and 2 for aneurysm clippings. There were done a transesfenoidal approach and a lumbar microdiscectomy. 2 of the 6 patients given craniotomies required external ventricular drainage before the operation. 5 elective cesareans were done in the group of patients given the craniotomies whilst of the rest the pregnancy was allowed to bring to term for reasons of pulmonary maturity. In our patients there were no cases of therapeutic abortion. There was found no morbidity no mortality neither in the mother nor in the fetus related to surgery.

CONCLUSIONS

In our experience with pregnant patients who suffered from neurosurgical lesion and in the experience we got from the revision of the related literature, the surgery of intracranial lesions is well tolerated by the mothers and the fetus. It must though be considered, the possibility of labor through cesarean depending on the fetus' lung maturity.

Neurosurgical management of intracranial lesions in the pregnant patient: a 36-year institutional experience and review of the literature

Object

A review of the literature has revealed scant data related to neurosurgical treatment of gravid patients. The authors reviewed their experience with the neurosurgical treatment of pregnant women to better characterize the optimal management strategies for intracranial pathological entities in this population.

Methods

Between July 1969 and July 2005, 34 patients with documented pregnancy and concomitant intracranial pathological entities were treated at the authors' institution. The average age of the gravid patients at presentation was 27 ± 6 years. Twelve patients harbored vascular and 14 patients harbored neoplastic lesions. Four gravid patients suffered from traumatic intracranial hemorrhage, 2 had primary intracerebral hemorrhage, and 2 had hydrocephalus. The medical records of these patients were reviewed to assess the outcome for the mothers and fetuses.

Results

Nineteen pregnant patients (56%) underwent a neurosurgical procedure after induction of general anesthesia. Of these, 14 (74%) underwent craniotomies for clipping/resection of their lesion, 2 (10%) underwent stereotactic biopsies, and 3 (16%) underwent CSF shunting procedures. Three patients (9%) delivered by cesarean section followed by their neurosurgical procedure, and 5 (15%) underwent therapeutic abortion preoperatively to allow for radiation therapy early in their pregnancy (4 of these patients underwent surgery prior to their therapeutic abortion). Eleven patients (32%) were treated nonoperatively while pregnant, and 3 of these received their treatment after delivery. There was no operative maternal mortality or permanent morbidity. The fetuses did not suffer from any complications related to the mother's neurosurgical procedure.

Conclusions

Based on the authors' experience and a review of the literature, surgery for intracranial lesions in pregnant patients is generally well tolerated by both mother and fetus. Preoperative delivery by cesarean section of term or near-term babies is reasonable. Some patients treated conservatively may deteriorate and require an operation.

Trauma in pregnancy

Over the past 60 years, trauma has become the leading cause of morbidity and mortality in the pregnant patient. The emotional and physiological challenges of treating two patients simultaneously adds to an already stressful situation. Resuscitation of the pregnant trauma patient is discussed from the prehospital setting to disposition. Also discussed are non-invasive monitoring tools, such as tocodynanomometry and ultrasonography.
