[Subarachnoid hemorrhage syndrome and its aneurysmal etiology. From Morgagni to Moniz, Dott and Dandy. A historical overview].

Although obvious today, the concept of subarachnoid hemorrhage due to ruptured intracranial aneurysms emerged slowly in medical knowledge with the clinical and pathological observations of many perspicacious authors beginning with Morgagni in the middle of the eighteenth century. This body of clinical material made it possible for Symonds in 1924 to affirm this concept on clinical and pathological grounds just a few years before Egas Moniz performed the first cerebral angiograms and such pioneers as Norman Dott and Walter Dandy the first direct attacks on cerebral aneurysms.
