Abstract

Objective : A retrograde clinical study was undertaken to determine the effect of opening lamina terminalis on the development of hydrocephalus after aneurysmal subarachnoid hemorrhage(SAH). We compared the incidence ratios of the development of hydrocephalus with and without opening lamina terminalis during operation after aneurysmal SAH. Patients and Methods : From Oct. 1996 to Sep. 1998, we performed 138 aneurysm surgery for 122 patients. In 98 cases, the lamina terminalis was opened to make direct cerebrospinal fluid flow from the third ventricle to subarachnoid space for prevention of delayed hydrocephalus. We compared the incidence of hydrocephalus after opening lamina terminalis to those without opened lamina terminalis. Results : In 95 cases, the hydrocephalus was noticed in 2 cases(2.2%). It is significantly lower in the group with opening lamina terminalis than the group without opening lamina terminalis(about 10%). Conclusion : It is simple and easy procedure to open the lamina terminalis during aneurysm surgery. With this maneuver, we could reduce the incidence of hydrocephalus after aneurysmal spontaneous SAH. Thus, it is considered that the opening lamina terminalis is one of the effective methods for preventing the development of hydrocephalus after aneurysmal spontaneous SAH.
