In spite of some meritorious analysis, further discussion is helpful to understand the actual state of art. Retreatment and rebleeding rates clearly favors clipping, although short-term functional outcome seems to be beneficial for clipping, while this different is not such if we perform the comparison at a longer follow up. Longterm follow ups and cost analysis are mandatory to have a clear view of the current picture in treatment of subarachnoid hemorrhage. Treatment strategy should be made by a multi-disciplinary team in accredited centers with proficient experience in both techniques.展开更多

The diagnosis of CVT is often missed or delayed because of non- specific clinical manifestations, and brain computerized tomography （CT） may easily be misinterpreted.展开更多

The radiographic vasospasm can reach up to 90% of aneurysmal SAH. Materials and Methods: 139 consecutive patients admitted to Cairo University Hospitals from June 2013 to September 2014 with SAH who had been enrolled in a retrospective controlled study were analyzed retrospectively for the occurrence of vasospasm. The data collected from the charts of Cairo University Hospitals were the patient’s demographics, clinical presentation, aneurysm location, treatment modality, and Glasgow Outcome Scale (GOS) scores. We excluded 24 patients with nonaneurysmal SAH, 3 internal carotid artery (ICA) aneurysms, 7 with multiple aneurysms and 4 patients died before treatment. Results: 72 males and 29 females were included in the study, mean age 53.5 ± 11.5 years. Twelve patients had aneurysms located in the vertebral artery group, 24 had middle cerebral artery aneurysms, 11 had pericallosal aneurysms, and 54 patients had anterior communicating artery (ACoA) complex aneurysms. Radiographic vasospasm occurred in 62.4% with the highest incidence (75.9%) at the ACoA complex group. Symptomatic vasospasm occurred in 48.5% with the highest incidence (63%) at the anterior communicating artery complex aneurysm location. The mean GOS at 6 months follow-up was 4.2. The worse GOS was found in the vertebral artery (VA) aneurysm group with a mean of 3.75. Conclusion: Aneurysms of the anterior communicating artery complex group have a greater risk of both radiographic and clinical vasospasm. Also, the worse 6 months follow-up GOS when an aneurysm was located in the VA group.展开更多

However, several hypotheses are put forward and are mostly found in Virchow’s triad. We report the case of a man who suffered subarachnoid hemorrhage by rupture of a blister aneurysm of the P1 segment of the left posterior cerebral artery. A control arteriography performed one week after the rupture showed a disappearance of the aneurysm and a significant vasospasm of the carrier artery. Angiograms performed at 3 weeks and 3 months confirmed this disappearance of the aneurysm and a return to normal artery size. Clinically the patient was doing well. Therefore his aneurysm was spontaneously declared cured. Several studies are needed to clarify the natural history of spontaneously thrombosed aneurysms and elucidate their occurrence mechanism in order to improve the management of intracranial aneurysmal pathology.展开更多
