Anterior communicating artery aneurysm rupture: An unusual cause of acute subdural hemorrhage

Acute Subdural Hematoma Without Subarachnoid Hemorrhage Caused by Ruptured A1-A2 Junction Aneurysm

“…7,11,13) Outcome was good in 17 patients, 1,5,7,8,[10][11][12][13][14][15][16]19,24,25) but poor in 10 patients, with 5 disabled and 5 dead patients. 4,8,9,15,[21][22][23]26,28,29) The aneurysms in the poor prognosis group originated from the ICA-PcomA in 5 cases, the MCA in 2 cases, the distal anterior cerebral artery (ACA) in 2 cases, and the AcomA in 1 case, similar to the overall series. These patients had lower increase in intracranial pressure due to massive ASDH.…”

“…10,15,16,19) Surgery was performed in 26 cases. 1,5,[7][8][9][10][11][12][13][14][15][16][17]19,[22][23][24][25][26]28,29) Aneurysm clipping and hematoma evacuation were performed in 17 cases, 1,8,10,12,15,16,19,22,24-26, 28,29) and only clipping in 4 cases, including the present case. 7,11,13) Outcome was good in 17 patients, 1,5,7,8,[10][11][12][13][14][15][16]19,24,25) but poor in 10 patients, with 5 disabled and 5 dead patients.…”

Migrating Subdural Hematoma without Subarachnoid Hemorrhage in the Case of a Patient with a Ruptured Aneurysm in the Intrasellar Anterior Communicating Artery

“…Of the 28 cases reported in the literature, 16 were aneurysms involving the internal carotid artery and posterior communicating artery, 4 were aneurysms of the middle cerebral artery, 4 were aneurysms of the distal anterior cerebral artery, 3 were aneurysms of the AcomA, and 1 was a bifurcation aneurysm of the internal carotid artery. [1][2][3][4][5][6][7] Several mechanisms have been proposed to explain the occurrence of SDH after aneurysmal rupture. An aneurysm may become adherent to local arachnoid granulation as a result of previous minor hemorrhage.…”

Aneurysmal Rupture Without Subarachnoid Hemorrhage: A Case Report Abstract

“…[1][2][3][4] The incidence of SAH with IPH, IVH and SDH is 40%, 17% and 35%, respectively. [5][6][7] However, the presence of a ruptured aneurysm presenting as IPH, IVH or SDH without SAH is extremely rare.…”
