Dementia and parkinsonism are rarely observed in dural arteriovenous fistula. Here, we report a case of a 63-year-old man with recurrent dural arteriovenous fistula, who developed progressive dementia and parkinsonism as a result of a dural arteriovenous fistula at the torcular herophili. A sinus thrombosis induced the abnormal cortical venous reflux from the isolated straight sinus, resulting in the deep venous congestion of the thalamus and basal ganglia, which led to dementia and parkinsonism. However, the third endovascular embolization ameliorated memory disturbance and apathy with a slight improvement of parkinsonism. Although recoveries from dural arteriovenous fistula-associated neurological deficits are variable depending on the severity, duration and, furthermore, selective vulnerability of the responsible ischemic lesions, early treatment should be essential for better recovery.

OBJECTIVE The aim of this study was to evaluate whether combined gene therapy with vascular endothelial growth factor (VEGF) plus apelin during indirect vasoreconstructive surgery enhances brain angiogenesis in a chronic cerebral hypoperfusion model in rats.METHODS A chronic cerebral hypoperfusion model induced by the permanent ligation of bilateral common carotid arteries (CCAs; a procedure herein referred to as "CCA occlusion" [CCAO]) in rats was employed in this study. Seven days after the CCAO procedure, the authors performed encephalo-myo-synangiosis (EMS) and injected plasmid(s) into each rat's temporal muscle. Rats were divided into 4 groups based on which plasmid was received (i.e., LacZ group, VEGF group, apelin group, and VEGF+apelin group). Protein levels in the cortex and attached muscle were assessed with enzyme-linked immunosorbent assay (ELISA) on Day 7 after EMS, while immunofluorescent analysis of cortical vessels was performed on Day 14 after EMS.RESULTS The total number of blood vessels in the cortex on Day 14 after EMS was significantly larger in the VEGF group and the VEGF+apelin group than in the LacZ group (p < 0.05, respectively). Larger vessels appeared in the VEGF+apelin group than in the other groups (p < 0.05, respectively). Apelin protein on Day 7 after EMS was not detected in the cortex for any of the groups. In the attached muscle, apelin protein was detected only in the apelin group and the VEGF+apelin group. Immunofluorescent analysis revealed that apelin and its receptor, APJ, were expressed on endothelial cells (ECs) 7 days after the CCAO.CONCLUSIONS Combined gene therapy (VEGF plus apelin) during EMS in a chronic cerebral hypoperfusion model can enhance angiogenesis in rats. This treatment has the potential to be a feasible option in a clinical setting for patients with moyamoya disease.

We present the case of a de novo vertebral artery dissecting aneurysm (VADA) after endovascular trapping of a ruptured VADA on the contralateral side. The first ruptured VADA involved the posterior inferior cerebellar artery, which was successfully treated by endovascular internal trapping using a stent. A follow-up study at 3 months revealed a de novo VADA on the contralateral side. The second VADA was successfully embolized using coils while normal arterial flow in the vertebral artery was preserved using a stent. Increased hemodynamic stress may cause the development of a de novo VADA on the contralateral side.

Perioperative management is critical for positive neurosurgical outcomes. In order to maintain safe and authentic perioperative management, a perioperative management center (PERIO) was introduced to patients of our Neurosurgery Department beginning in June 2014. PERIO involves a multidisciplinary team consisting of anesthesiologists, dentists/dental hygienists/technicians, nurses, physical therapists, pharmacists, and nutritionists. After neurosurgeons decide on the course of surgery, a preoperative evaluation consisting of blood sampling, electrocardiogram, chest X-ray, and lung function test was performed. The patients then visited the PERIO clinic 7-14 days before surgery. One or two days before surgery, the patients without particular issues enter the hospital and receive a mouth cleaning one day before surgery. After surgery, postoperative support involving eating/swallowing evaluation, rehabilitation, and pain control is provided. The differences in duration from admission to surgery, cancellation of surgery, and postoperative complications between PERIO and non-PERIO groups were examined. Eighty-five patients were enrolled in the PERIO group and 131 patients in the non-PERIO group. The duration from admission to surgery was significantly decreased in the PERIO group (3.6 +/- 0.3 days), compared to that in the non-PERIO group (4.7 +/- 0.2 days). There was one cancelled surgery in the PERIO group and six in the non-PERIO group. Postoperative complications and the overall hospital stay did not differ between the two groups. The PERIO system decreased the duration from admission to surgery, and it is useful in providing high-quality medical service, although the system should be improved so as not to increase the burden on medical staff.

<p>Objective: Unidentified fever, headache, and gastrointestinal symptoms after endosaccular coil embolization are occasionally observed in patients with unruptured cerebral aneurysms. We defined these symptoms as post coiling syndrome (PCS) and analyzed the clinical risk factors involved.</p><p>Methods: We applied the PCS diagnostic criteria based on the scoring of symptoms, which include fever, headache, nausea, and/or vomiting. Thirty-six consecutive patients were included in this retrospective study. Systematic follow-up included clinical and blood examinations.</p><p>Results: Based on our criteria, 11 of 36 patients were diagnosed with PCS. Between patients in the PCS group and patients in the non-PCS group, we recognized significant differences in age (63.4 ± 12.5 vs. 53.8 ± 12.9, respectively; p <0.029) as patient background and in aneurysmal diameter (9.96 ± 4.24 vs. 6.48 ± 3.06, respectively; p <0.049), aneurysmal volume (242 ± 254 vs. 87.9 ± 70.1, respectively; p <0.015), total coil length (122 ± 106 vs. 39.1 ± 25.7, respectively; p <0.0021), and volume embolization ratio as aneurysmal data (41.9 ± 8.1 vs. 30.7 ± 8.5, respectively; p <0.0019). In addition, we recognized a significant difference in postoperative leukocytosis as an inflammatory factor.</p><p>Conclusions: Patient age, aneurysmal diameter, aneurysmal volume, total coil length, and volume embolization may enable the prediction of PCS.</p>

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年

掲載種別：研究論文（学術雑誌）

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.

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.

Object. The effect on clinical outcomes of symptomatic vasospasm after aneurysmal subarachnoid hemorrhage (SAH) in patients over 80 years who underwent coil embolization was evaluated. Methods. Forty-four cases were reviewed and divided into two groups according to patient age: Group A, 79 years or younger, and Group B, 80 or older. Patient characteristics, prevalence of symptomatic vasospasm, modified Rankin Scale (mRS) scores at discharge and frequency of symptomatic vasospasm in patients with mRS scores of 3-6 were analyzed. Results. Thirty-two (73%) of the 44 cases were categorized as Group A and 12 (27%) as Group B. Group B had a significantly higher prevalence of symptomatic vasospasm compared to Group A (P = 0.0040). mRS scores at discharge were significantly higher in Group B than in Group A (P = 0.0494). Among cases with mRS scores of 3-6, there was a significantly higher frequency of symptomatic vasospasm in Group B than in Group A (P = 0.0223). Conclusions. In our cohort of aneurysmal SAH patients treated by coil embolization, patients over 80 years of age were more likely to suffer symptomatic vasospasm, which significantly correlated with worse clinical outcomes, than those 79 years and under.
