“…In the current series, patients with NPM-SAH or PM-SAH had a different outcome. Patients with PM-SAH had an excellent outcome, as in other series,7 8 15 16 21 24–26 which also confirmed that the patients were classified correctly. However, excluding Fi3 (favorable outcome in only 71% of the patients; table 1), patients with NASAH without Fi3 also had an excellent chance of a favorable outcome, similar to patients with PM-SAH (both about 90%; table 2).…”

“…Also, in about 15–25% of patients with subarachnoid hemorrhage (SAH), cerebral angiography, CT scan, and spinal MRI are negative for aneurysms or other vascular malformations 2–5. Data from series with small patient numbers showed a similar outcome between perimesencephalic (PM) and non-PM (NPM) SAH but larger series, maybe due to the improved statistical power, identified different outcomes between PM-SAH and NPM-SAH 6 7. In a recent review of PM-SAH, most series had a patient cohort of about 50 patients and only one paper had a cohort of more than 150 patients 8.…”

Patients with NASAH without a Fi3 bleeding pattern had a similar excellent outcome to patients with PM-SAH. Patients with Fi3 had a high risk for early hydrocephalus, CVS, DCI, and an unfavorable outcome, similar to patients with aneurysmal SAH. After multivariate analysis, early hydrocephalus, elderly patients, and Fi3 were identified as negative prognostic factors. Therefore, patients with Fi3 are at risk and need careful clinical observation.

“…However, data on patients with spontaneous NASAH are commonly based on case series and are therefore rare . But even more, data assessing the long‐term outcome are scarce and lacking for physiological and psychological outcome in a series with more than 50 patients. Our neurovascular database was therefore analyzed concerning patients suffering from NASAH.…”

Excluding rolph, only patients with a PM-SAH have a similar QoL at long-term follow-up compared to the standard population. Patients with NPM-SAH have a significantly decreased QoL in long-term follow-up. Furthermore, the Fisher 3 blood pattern group in particular had a significantly worse outcome - at short-term and long-term follow-up. Therefore the NPM-SAH group was stratified into patients with Fisher 3 blood pattern and patients without Fisher 3 in further investigations.

“…Aneurysm, arteriovenous malformation and cavernous malformation are the most common causes of non-traumatic intracranial hemorrhages [3][4][5]. Conventional catheter angiography is the gold standard for diagnosis of vascular abnormality; however; other imaging modalities such as CTA and MRA can help to find out about vascular abnormalities [6][7][8]. Intracranial aneurysms are the most common causes of non-traumatic intracranial hemorrhage, occurring in 60%-85% of cases [9,10].…”

Background and Aim:This study aimed at analyzing the demographic characteristics of the patients with non-traumatic intracranial hemorrhage, their angiographic results and the correlation between computed tomography (CT) scan and angiography findings. Methods and Materials/Patients:In a descriptive study, we retrospectively reviewed the records of the patients with non-traumatic intracranial hemorrhage based on their brain CT or lumbar puncture findings from 2011 to 2017. For all patients, four vessel catheter angiography via the femoral approach was performed in the Medical Imaging Center of Kermanshah University of Medical Sciences, Iran. Results:We investigated 143 cases with non-traumatic intracranial hemorrhage which was indicated in CT findings (91.61%) or lumbar puncture (8.39%). Of 143 patients, 64 (44.8%) were men and 79 (55.2%) women (mean age 53.7±12.1 years old). Moreover, 104(72.7%) patients had Subarachnoid Hemorrhage (SAH), 19(13.3%) of them had Intracranial Hemorrhage (ICH), 8(5.6%) ones had Intraventricular Hemorrhage (IVH) and 12(8.4%) patients had normal brain CT. There were 100 cases of aneurysm (69.93%), 13 cases of Arteriovenous Malformations (AVM) (9.09%), 28 cases with negative angiograms (19.58%), and 2 cases with other pathologies (1.4%). Seven (4.89%) cases of multiple aneurysms were also recorded. Of 13 patients with AVM, 8(61.5%) patients had AVM in parieto-occipital region, 2(15.4%) in temporal, 1(7.7%) in frontal region and 2(15.4%) had deep AVM. Two (1.4%) patients with SAH had dural AVF. Twenty-eight (19.6%) patients had negative angiogram, 22 cases of them had second angiography after one to two weeks. The most common positive finding in the second angiogram was Acom aneurysm (18.18%). Conclusion:Aneurysms and AVMs are the most common causes of non-traumatic intracranial hemorrhage. The most common site of intracranial aneurysms is the circle of Willis. A second angiogram after one to two weeks is necessary in most patients with negative results in first angiography after non-traumatic intracranial hemorrhage.
