It is known that the prognosis of spontaneous SAH(subarachnoid hemorrhage) of undetermined cause is generally favorable. Yet, the natural history and pathogenesis of SAH of undetermined cause remain controversial and patients management is largely empirical. 42 cases of non-traumatic SAH of undetermined cause of a total of 415 cases of SAH treated during a 5-year period(1991-1996) were available for this study. What should be done when angiography is negative after SAH? This study was undertaken to present a more definitive management in preventing rebleeding after SAH of undetermined cause. This study show that explorative craniotomy for aneurysmal operation is warranted, despite negative cerebral panangiograms, if the patient manifests the classical signs and symptoms of SAH and definite subarachnoid blood in CT(computed tomogram) or direct lumbar puncture and any suspicious lesions in cerebral panangiography, particularly the AcoA(anterior communicating artery) region.
Key Words: SAH(subarachnoid hemorrhage) of undetermined cause; Panangiography; Explorative craniotomy; AcoA(anterior communicating artery)
