Temporary hidden aneurysms during pregnancy. A case report.

SUMMARY: There are a number of reports on cerebral aneurysmal ruptures during pregnancy. Although the cerebral aneurysmal rupture is quite rare during pregnancy, it leads to a high maternal mortality; which gives rise to a clinical significance. We have encountered a number of multiple cerebral aneurysms during pregnancy, and the ruptured cases were successfully treated with the coiling procedures. The coiling is found to be a good treatment method for ruptured aneurysms during pregnancy. The cerebral angiogram is the gold standard diagnostic method for detecting cerebral aneurysms. However, 1.8-20% of the cases are reported to be false negative in initial angiography, and only up to 20% can be diagnosed even with the additional angiographies.A special attention for a hidden aneurysm should also be required while managing the patients.
