Computed tomographic evaluation of hemorrhage secondary to intracranial aneurysm

Computed tomography in aneurysmal subarachnoid haemorrhage.

“…This information was available i.n 68 patients, and the hypertensive history was correlated with the scan appearance. All the patients underwent a,ngiography prior to surgery, and the detection Timing of CT scan following the bleed [2][3][4][5][6][7][8][9][10][11][12][13][14][15] of spasm by the radiologist reviewing the initial angiograms, performed within 15 days of the SAH, was noted. The proportion of patients in each scan category showing angiographic spasm was calculated, as was the timing of angiography in relation to the bleed.…”

Aneurysmal subarachnoid hemorrhage: Prevention of delayed ischemic dysfunction with intravenous nimodipine

“…In 1976, DAvis and co-authors reported on computed tomographic scanning (CT) of aneurysmal SAH [13] and in the following years CT rapidly came into routine use in the acute evaluation of patients with a ruptured aneurysm. Evidence increased that the amount of extravasated blood within the intracranial compartment correlates positively with the later development of vasospasm and ischemic dysfunction [22,42,46].…”

Spontaneous Subarachnoid Hemorrhage: Assessment of Prognosis and Initial Management in the Intensive Care Unit

“…CT Findings CT has been demonstrated to detect the pattern of subarachnoid bleeding, presence of concomitant ICH and IVH, hydrocephalus, and cerebral infarction [72]. As outlined previously here, timing of this examination must be accounted for [45,73].…”

“…As outlined previously here, timing of this examination must be accounted for [45,73]. A localized clot or characteristic bleeding pattern may point to the site of aneurysm rupture [72,74,75]. Isolated IVH may be caused by rupture of aneurysms of the anterior cerebral or anterior communicating arteries [75] or posterior inferior cerebellar artery [76].…”
