Aneurysm location and clipping versus coiling for development of secondary normal-pressure hydrocephalus after aneurysmal subarachnoid hemorrhage: Japanese Stroke DataBank.
CONCLUSIONS Patients with low-grade SAH caused by a ruptured MCA aneurysm had a low risk for the development of sNPH. In contrast, patients with high-grade SAH caused by a ruptured ACA aneurysm had a higher risk for sNPH. Endovascular coiling might confer a lower risk of developing sNPH than microsurgical clipping.

Acute Stroke Care in Korea in 2013-2014: National Averages and Disparities.
CONCLUSION: This study describes the current status of acute stroke care in Korea. Despite quite acceptable quality of stroke care, it suggests regional and hospital disparities. Expansion of stroke units, stroke center certification or accreditation, and connections between stroke centers and emergency medical services are highly recommended.

E-011 SOFIA Distal Access Catheter for Endovascular Treatment of Acute Ischemic Stroke Using Combined Mechanical and Aspiration Thrombectomy
ConclusionSOFIA is a safe and effective intermediate catheter for mechanical and aspiration thrombectomy in acute stroke intervention. In conjunction with stent retrievers and suction aspiration technique, successful revascularization was 94%, with average number of passes of 1.6. There were no complications directly attributable to the use of SOFIA.Abstract E-011 Figure 1DisclosuresJ. Wong: None. H. Do: 2; C; MicroVention, Inc. N. Telischak: None. A. Moraff: None. M.

Initial experience with SOFIA as an intermediate catheter in mechanical thrombectomy for acute ischemic stroke
Conclusions Mechanical and aspiration thrombectomy with SOFIA is safe and effective with high revascularization rates. Its trackability, stability, and luminal size make SOFIA suitable for stroke intervention.

Development and Validation of Scoring Indication of Surgical Clipping and Endovascular Coiling for Aneurysmal Subarachnoid Hemorrhage from the Post Hoc Analysis of Japan Stroke Data Bank.
Authors: Yoshiyama M, Ikawa F, Hidaka T, Matsuda S, Ozono I, Toyoda K, Kobayashi S, Yamaguchi S, Kurisu K Abstract There are no scoring methods for optimal treatment of patients with aneurysmal subarachnoid hemorrhage (aSAH). We developed a scoring model to predict clinical outcomes according to aSAH risk factors using data from the Japan Stroke Data Bank (JSDB). Of 5344 patients initially registered in the JSDB, 3547 met the inclusion criteria. Patients had been diagnosed with aSAH and treated with surgical clipping or endovascular coiling between 1998 and 2013. We performed multivariate logistic regression for po...

Extensive stretching of intracranial aneurysm coil causing TIAs
A 58-year-old man with a history of ruptured posterior cerebral artery aneurysm, repaired with coil embolization 5 years previously, presented with right hemi-numbness lasting 30 minutes. Cerebral MRI did not reveal acute stroke. CT angiogram showed a stretched wire complex extending through the posterior communicating artery, down the carotid artery, and into the most inferior visualized portion of descending aorta, terminating in a loosely coiled wire (figure, A and B). A transesophageal echocardiogram showed evidence of a possible thrombus on the coil in the aortic arch (figure, C and D; video on the Neurology® Web ...

Analysis of outcome at discharge after aneurysmal subarachnoid hemorrhage in Japan according to the Japanese stroke databank
AbstractThe outcomes at discharge for ruptured cerebral aneurysms after subarachnoid hemorrhage (SAH) were investigated using data from the Japanese stroke databank. Among 101,165 patients with acute stroke registered between 2000 and 2013, 4693 patients had SAH caused by ruptured saccular aneurysm. Of these, 3593 patients (1140 men and 2453 women; mean age 61.3  ± 13.7 years) were treated by surgical clipping (SC) and/or endovascular coiling (EC). The outcomes of modified Rankin scale (mRS) at discharge were compared between the SC and EC groups. There were 2666 cases in the SC group, 881 cases in the EC group, and 46...

Endovascular management of extracranial occlusions at the hyperacute phase of stroke with tandem occlusions
Conclusions ervical occlusion with coils and thrombectomy with stent-retrievers may be relevant to prevent early embolic recurrence in cervical occlusions with intraluminal thrombus. Stent-retrievers should be further assessed as a first-line approach, since delayed stroke may occur following occlusion with coils.

Relationship between patient safety indicator events and comprehensive stroke center volume status in the treatment of unruptured cerebral aneurysms.
CONCLUSIONS In the treatment of unruptured cerebral aneurysms, PSI events occur relatively frequently and are associated with significant increases in morbidity and mortality. In patients treated at institutions achieving the volume thresholds for CSC certification, the likelihood of having a PSI event, and therefore the likelihood of poor outcome and mortality, was significantly decreased. These improvements are being driven by the improved outcomes in surgical patients, whereas outcomes and mortality in patients treated endovascularly were not sensitive to the CSC volume status of the hospital and showed no significant r...

The role of interventional neuroradiology in treatment of hemorrhagic stroke.
Abstract Treatment of hemorrhagic strokes necessitates hospitalization in an accommodated hospital offering the possibility of a multidisciplinary approach. In this setting, over recent years interventional radiology has become increasingly important from the diagnostic as well as the therapeutic standpoint. In the context of subarachnoid hemorrhage by intracranial aneurysm rupture, the NICE (National Institute for Health and Clinical Excellence) and ASA (American Stroke Academy) recommendations suggest that endovascular coiling should be considered as an alternative to surgical clipping (class I, level of evidenc...

Effects of case volume and comprehensive stroke center capabilities on patient outcomes of clipping and coiling for subarachnoid hemorrhage.
CONCLUSIONS: The effects of case volume and CSC capabilities on in-hospital mortality and short-term functional outcomes in SAH patients differed between patients undergoing clipping and those undergoing coiling. In the modern endovascular era, better outcomes of clipping may be achieved in facilities with high CSC capabilities. PMID: 32168489 [PubMed - as supplied by publisher]

Nomogram for predicting delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage in the Chinese population
The incidence of stroke is high worldwide1 and is the leading cause of death in China presently.2,3 Subarachnoid hemorrhage caused by ruptured intracranial aneurysm is a subtype of severe stroke that occurs suddenly in seemingly healthy individuals with generally poor prognosis.4 Surgical clipping and endovascular coiling are effective treatment modalities for patients with aneurysmal subarachnoid hemorrhage (aSAH). Delayed cerebral ischemia (DCI) is a complication of aSAH, occurring in up to 30% of patients,5 and is an important cause of disability and death, often leading to deterioration of patients ’ condition or quality of life.
