[Surgery of grade "0" aneurysms. Report of 22 cases].
Subarachnoid hemorrhage secondary to aneurysms rupture is still a devastating disease, in spite of advances of medical and surgical management. Mortality remains about 50% at the initial event, and less of 30% of survivors recover their previous level. The authors present a series of 22 patients with grade "0", aneurysms that had not bled, operated on during a six year period, with no mortality and a very low morbidity (less than 5%). An analysis of the cases and a bibliographic revision is made, concluding that most of those aneurysms should be treated, for the surgical risks are lower than those of the disease itself, and also lower than those of the endovascular therapy. lt is believed that the advances in the diagnosis and treatment of unruptured aneurysms will reduce the high morbimortality they cause after the bleeding.
