Spinal Surgery 29 ( 1 ) 53 - 58 2015

Language：Japanese Publisher：The Japanese Society of Spinal Surgery

Spinal hemangioblastomas are benign, and total surgical resection is the standard treatment method used. However, hypervascular tumors may have excessive operative blood loss if the tumors are divided. We encountered a case of cauda equina hemangioblastoma with extraordinary blood supply, which was treated with preoperative embolization. A 49-year-old woman with von Hippel-Lindau disease who had undergone multiple surgeries for intracranial/extracranial hemangioblastomas had lumbago and leg pain. Magnetic resonance images revealed intradural spinal tumors at the L4-S1 vertebral level, with remarkable gadolinium enhancement. The patient was referred to our hospital, after a plan of total resection had been abandoned elsewhere because of the high flow feeders and high pressure of the tumors. Preoperative embolization was performed with consequent disappearance of the arterial blood supply to the tumor. Two days later, the tumor was resected subtotally with reduced tension and a little blood loss. The patient's symptoms resolved soon after surgery. Selective preoperative embolization for a spinal hemangioblastoma with a rich blood supply is a valid option as an adjuvant to the complete surgical resection of a tumor.

Pathophysiology of moyamoya disease

Tomohito Hishikawa, Masafumi Hiramatsu, Koji Tokunaga, Kenji Sugiu, Isao Date

Japanese Journal of Neurosurgery 24 ( 4 ) 239 - 243 2015

Language：Chinese Publisher：Japanese Congress of Neurological Surgeons

In this article, we introduce cutting-edge knowledge pertaining to the pathophysiology of moyamoya disease from the viewpoint of angioarchitecture and genetic analysis. A complementary relationship among the anterior circulation(AC), the posterior circulation(PC)and the external carotid artery(ECA)system is involved in the pathophysiology of moyamoya disease. Suzuki’s grading is representative of the interaction between the AC and ECA, and it has traditionally played a leading role in evaluating disease progression. The interaction between the AC and PC is related to hemodynamic ischemia. There is a difference between pediatric and adult moyamoya patients in the interaction between the AC and PC. The analysis of the RNF213 gene is noteworthy as a new approach to understanding the pathophysiology of moyamoya disease. The prognosis and responsiveness to revascularization surgery can be predicted on the basis of genetic analysis. Although gene therapy for moyamoya disease is only now just in the basic experimental studies stage, it can be expected to emerge as an assisting modality for indirect revascularization surgery.

Long-term outcomes in adult patients with ischemic-type moyamoya disease involving posterior circulation International journal

Tomohito Hishikawa, Koji Tokunaga, Kenji Sugiu, Isao Date

ACTA NEUROCHIRURGICA 156 ( 9 ) 1745 - 1751 2014.9

Language：English Publisher：SPRINGER WIEN

The object of this study was to compare the long-term outcomes in adult patients with moyamoya disease (MMD) with posterior circulation involvement (PCi) treated through surgical revascularization with those in adult patients without PCi.
The records of 32 consecutive adult patients with ischemic-type MMD who were treated with revascularization were reviewed. Twelve of these patients (38 %) had PCi at initial onset. Clinical characteristics of the patients with PCi were compared to those without PCi. Neurological outcomes were assessed using the modified Rankin Scale (mRS) in the preoperative and postoperative follow-up periods. A five-year Kaplan-Meier stroke risk was calculated.
The frequency of presenting with infarction was significantly higher among patients with PCi than among those without PCi (p = 0.006). mRS scores in the preoperative period were significantly higher in patients with PCi than in patients without PCi (p = 0.0004). There were no significant differences in mRS scores between the preoperative and postoperative follow-up period in patients with PCi (p = 0.3), nor were there any between the preoperative and postoperative follow-up periods in patients without PCi (p = 0.2). The five-year Kaplan-Meier risk of surgical morbidity and ipsilateral stroke was 14.3 % in surgically treated hemispheres with PCi versus 14.9 % in surgically treated hemispheres without PCi (p = 0.96).
PCi at initial onset was significantly correlated with poor outcome. Revascularization for the middle cerebral artery territory in patients with PCi was effective at preventing recurrent ischemic stroke.

Nationwide survey of the nature and risk factors of complications in embolization of meningiomas and other intracranial tumors: Japanese Registry of NeuroEndovascular Therapy 2 (JR-NET2) International journal

Language：English Publisher：SPRINGER

Embolization of intracranial tumor is widely performed in Japan, mainly before neurosurgical resection. A retrospective, multicenter, observational study in Japan was conducted to clarify the nature, frequency, and risk factors of complications in intracranial tumor embolization.
Patients were derived from the Japanese Registry of NeuroEndovascular Therapy 2 (JR-NET2). A total of 20,854 patients were enrolled in JR-NET2, of which 1,018 patients (4.88 %) with intracranial tumors underwent embolization. The primary end point was the proportion of patients with a modified Rankin scale (mRS) score of 0-2 (independency) at 30 days. The secondary end point was the occurrence of complications related to the procedures. The risk factors of the occurrence of complications were studied.
The proportion of patients with mRS scores a parts per thousand currency sign2 at 30 days after procedure was 91.3 %. Complications occurred in 15 of the 1,012 patients (1.48 %). Multivariate analysis showed that embolization for tumors other than meningioma (OR, 4.626; 95 % CI, 1.347-14.59; p = 0.0105) was significantly associated with the development of complications.
The frequency of complications after intracranial tumor embolization was relatively low in this large Japanese cohort. Embolization for tumors other than meningioma was the only significant risk factor for the occurrence of complications.

Language：English Publisher：JAPAN NEUROSURGICAL SOC

The present study retrospectively analyzed the database of the Japanese Registry of Neuroendovascular Therapy 1 and 2 (JR-NET1&2) to determine annual trends, including adverse events and clinical outcomes at 30 days after undergoing neuroendovascular therapy. JR-NET1&2 are surveys that targeted all patients in Japan who underwent neuroendovascular therapy delivered by physicians certified by the Japanese Society of Neuroendovascular Therapy (JSNET) between 2005 and 2009. Medical information about the patients was anonymized and retrospectively registered via a website. Data from 32,608 patients were analyzed. The number of treated patients constantly increased from 5,040 in 2005 to 7,406 in 2009 and the rate of octogenarians increased from 7.0% in 2005 to 10.4% in 2009. The proportion of procedures remained relatively constant, but ratios of angioplasty slightly increased from 32.8% in 2005 to 33.7% in 2009. Procedural complications were associated more frequently with acute stroke (9.6%), ruptured aneurysms (7.4%), intracranial artery disease (ICAD) (5.4%), and arteriovenous malformation (AVM, 5.2%). The number of patients requiring neuroendovascular treatment in Japan is increasing and the outcomes of such therapy are clinically acceptable. Details of each type of treatment will be investigated in sub-analyses of the database.
