UNASSIGNED: Background   Negative angiography @entity510 , also known as idiopathic @entity510 (iSAH), is a challenging pathologic condition whose evolution and final outcome is difficult to predict with certainty. This article describes the clinical features, the type of complications and rates, as well as the final outcome of @entity1 with iSAH. Methods   A prospective evaluation of @entity1 with @entity510 was performed. @entity1 with a diagnosis of iSAH were included. Demographic data, clinical features, complication rates, and functional outcomes were all collected. iSAH cases were subsequently compared with @entity1 with @entity439 @entity510 (aSAH) taken from the same period. Results   Forty-nine @entity1 fulfilled the criteria for iSAH. @entity1 with aSAH presented with a worse clinical condition and had a larger amount of blood in the initial computed tomography (CT) scan than iSAH @entity1 . There were no differences in the incidence of acute @entity1276 , and there was a positive correlation with the Fisher score and the initial clinical status in both groups. @entity2553 was more frequent among @entity1 with aSAH, but the relationship between the incidence of @entity2553 and the amount of blood in the initial CT scan was not linear. Good functional outcome was present in   >   90% of iSAH @entity1 . Conclusions   Although iSAH generally has a good prognosis, it may be accompanied with serious complications. The incidence of acute @entity1276 in iSAH is similar to that in aSAH. There is a lower incidence of @entity2553 in iSAH than aSAH. A different relationship seems to exist between these complications and the amount of blood in the CT scan.
