After the initial subarachnoid hemorrhage (SAH), rebleeding is the major cause of morbidity and poor outcome, which is maximal in the first 24 h. We supposed that the coiling of ruptured intracranial aneurysms within 24 h of SAH is related to the improved clinical outcome compared with coiling 24 h after aneurysmal SAH.
We examined whether coiling ruptured aneurysms within 24 h of aneurysmal SAH is associated with better early 24 h and late 30 days outcome.
This prospective study was carried on 30 patients with aneurysmal SAH presenting to the Alexandria University Hospital and Insurance Main Hospital during the period from February 2013 to May 2014. They were divided into two groups: Group I (10 patients treated within 24 h of presentation) and Group II (20 patients treated after 24 h of presentation). Time interval from presentation to treatment were 78.60 and 10.60 h for subacute and hyperacute group, respectively. All patients were treated with endovascular coiling. Change between admission and immediate postoperative World Federation of Neurosurgeons classification Scale was measured for early outcome, while remote outcome was measured by modified Rankin Scale at 30 days follow-up.
There was a clinical improvement regarding early 24 h outcome (weighted by postoperative WFNS grade) and on late 30 days outcome (weighted by Modified Rankin Scale Score) in the group managed within 24 h versus who were treated after 24 h (P = 0.049 and P = 0.024, respectively). There was a significant decrease in the incidence of clinical rebleeding detected by postoperative computed tomography (CT) of the brain in patients undergoing aneurysm treatment within 24 h (P = 0.029).
The study affirms evidence that the management of ruptured intracranial aneurysms within 24 h of SAH is associated with better immediate and short-term clinical outcome.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 16 June 2016.
All research outputs
#20,333,181
of 22,877,793 outputs
Outputs from Frontiers in Neurology
#8,811
of 11,802 outputs
Outputs of similar age
#282,528
of 326,206 outputs
Outputs of similar age from Frontiers in Neurology
#46
of 55 outputs
Altmetric has tracked 22,877,793 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 11,802 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.3. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 326,206 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 55 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
