However, because the devices for SAC may cause mechanical injuries to the aneurysms, urokinase should be used cautiously for cerebral aneurysms, even if unruptured.Infra-optic course of the anterior cerebral artery (IOA) is rare and approximately 55 cases of this anomaly have been described. We present a case of a ruptured anterior communicating artery (ACoA) aneurysm arising at the junction between the left IOA and the bilateral A2 segments, at which the right A1 segment was absent. One of the recurrent arteries of Heubner branched off directly from the aneurysmal dome, and was obstructed at aneurysmal neck clipping via an anterior interhemispheric (AIH) approach. In this report, accompanied anatomical variations and surgical approaches for ACoA aneurysms with IOA are reviewed. An IOA is frequently associated with other vascular anomalies, and the origin of functionally important recurrent arteries of Heubner is also variable. ODM208 price Preoperative accurate evaluation of vessel structures and the maximal exposure at surgery are very important. Pterional approach from the ipsilesional side is reportedly to be safe, but interhemispheric approach is also suggested to be effective as to full exposure to recognize the perianeurysmal anatomical structures including potential vessel anomalies.Subacute subdural hematoma (SASDH) is a neurotraumatic entity. There are few reports of chronological changes of cerebral blood flow (CBF) on arterial spin labeling (ASL) and subcortical low intensity (SCLI) on fluid-attenuated inversion recovery (FLAIR) images of magnetic resonance imaging (MRI) observations from the injury onset, deterioration, to post-surgery. We reported a SASDH patient presenting postoperative cerebral hyperperfusion (CHP) syndrome with chronological changes of those findings. An 85-year-old woman fell and presented right ASDH. She was treated conservatively due to no neurological deficits. On day 3, ASL image revealed increased CBF against brain compression. On day 7, the CBF was normalized on ASL image, but SCLI was confirmed. On day 14, SCLI was strengthened. Then she developed left hemiparesis due to brain compression by SASDH. Considering age and comorbidities, we performed endoscopic hematoma removal under local anesthesia, and her neurological deficits improved after the surgery. On postoperative day 1, she newly presented left upper limb paresis. MRI revealed increased CBF and enhanced SCLI. We diagnosed CHP syndrome, and antihypertensive treatment improved the symptoms gradually. However, SCLI had been consistently observed, and CBF easily changed depending on the blood pressure, suggesting dysfunction of the CBF autoregulation. We showed the endoscopically treated SASDH patient with CBF's chronological changes on ASL images and SCLI on FLAIR images. Long-time brain compression would lead to dysfunction of the CBF autoregulation, and we should be careful about CHP syndrome after the endoscopic surgery for SASDH.Superficial temporal artery (STA)-middle cerebral artery (MCA) bypass is the standard surgical treatment for moyamoya disease (MMD). Local cerebral hyperperfusion (CHP) is one of the potential complications, which could enhance intrinsic inflammation and oxidative stress in MMD patients and accompany concomitant watershed shift (WS) phenomenon, defined as the paradoxical decrease in the cerebral blood flow (CBF) near the site of CHP. However, CHP and simultaneous remote reversible lesion at the splenium have never been reported. A 22-year-old man with ischemic-onset MMD underwent left STA-MCA bypass. Although asymptomatic, local CHP and a paradoxical CBF decrease at the splenium were evident on N-isopropyl-p-[123I] iodoamphetamine single-photon emission computed tomography 1 day after surgery. The patient was maintained under strict blood pressure control, but he subsequently developed transient delirium 4 days after surgery. MRI revealed a high-signal-intensity lesion with a low apparent diffusion coefficient at the splenium. After continued intensive management, the splenial lesion disappeared 14 days after surgery. The patient was discharged without neurological deficits. Catheter angiography 2 months later confirmed marked regression of posterior-to-anterior collaterals via the posterior pericallosal artery, suggesting dynamic watershed shift between blood flow supplies from the posterior and anterior circulation. Mild encephalitis/encephalopathy with a reversible splenial lesion could explain the pathophysiology of the postoperative splenial lesion in this case, which is associated with generation of oxidative stress, enhanced inflammation, and metabolic abnormalities. Rapid postoperative hemodynamic changes, including local CHP and concomitant WS phenomenon, might participate in the formation of the splenial lesion.Dystonia is a movement disorder that has various treatment options. For primary dystonia, stereotactic procedures such as deep brain stimulation (DBS) have demonstrated favorable outcomes. For secondary dystonia, however, the treatment outcomes remain inconclusive, and the heterogeneous etiological background is considered to contribute to the poor outcomes of the disease. Here, we report a rare pediatric case of post-stroke focal dystonia treated with conventional radiofrequency ventro-oral (Vo) thalamotomy. The patient was an 11-year-old girl with secondary focal dystonia in her right hand. The dystonia was considered to result from a stroke lesion in the putamen due to vasculitis following varicella-zoster virus infection. We hypothesized that the infarction of the putamen resulted in hyperactivity in the thalamus, and, thus, performed a radiofrequency Vo thalamotomy. Markedly decreased muscle tone in her right hand was noted immediately after surgery. However, the improvement was temporary, as her symptoms returned to baseline level by the 6-month follow-up. Although the observed improvement was temporary in this case, our findings may elucidate the possible mechanisms of secondary focal dystonia. Further studies are needed to establish an effective surgical treatment for secondary focal dystonia.
Posterior cerebral artery (PCA) aneurysms are extremely rare and can be difficult to treat. We report successful trapping and thrombectomy of a giant thrombosed P2 segment aneurysm via a transpetrosal approach.

A 62-year-old woman was admitted to our hospital with a progressive left hemiparesis. Magnetic resonance imaging (MRI) showed a 30 mm mass lesion in the right ambient cistern. On vertebral angiography, the right P2 trunk was deviated medially and inferiorly, and the right posterior temporal artery (PTA) was not visualized. We diagnosed a giant thrombosed aneurysm of the right PTA. Surgery was performed via a right posterior transpetrosal approach. The proximal P2 was identified above the oculomotor nerve in the ambient cistern, and a giant PTA aneurysm was found. After coagulating the distal PCA, a temporary clip was applied to the proximal P2, the aneurysm wall was incised, thrombus was removed, and a permanent titanium clip was applied to complete trapping. Postoperative MRI showed disappearance of the aneurysm. The patient's left hemiparesis was resolved 2 months after the operation, and she was discharged home.

Although trans-sylvian and subtemporal approaches are often performed for P2 aneurysms, they have difficulty identifying the distal PCA and may require excessive brain retraction. The transpetrosal approach can also be effective for giant thrombosed P2 aneurysms.

Infection and stroke are major complications after LVAD implantation. However, the incidence of intracranial mycotic aneurysm after LVAD implantation is rare, and with no standard of care. In this study, we describe a case of an intracranial mycotic aneurysm after LVAD implantation that was successfully treated with trans-arterial embolization (TAE) with N-butyl 2-cyanoacrylate (NBCA) via the brachial artery. A 49-year-old man with a history of implantation of LVAD for ischemic cardiomyopathy was admitted to our institution. He had infectious endocarditis and was administered systemic antibiotics. At 3 weeks after admission, intracranial mycotic aneurysm of the left posterior parietal artery was detected during a diagnostic examination for asymptomatic intracranial hemorrhage. Anticoagulant therapy was administered to prevent thromboembolic complications of LVAD implantation. Under local anesthesia, TAE with NBCA was performed via the brachial artery because of the tortuous anatomy of the origin of the innominate artery and implant of the aortic arch. The aneurysm was completely obliterated. The patient was discharged without neurological deficits. TAE using NBCA could be an effective modality for the treatment of intracranial mycotic aneurysm after LVAD implantation.There are some intraspinal cystic lesions presenting with myelopathy. We report a case of myelopathy caused by a possible thoracic interdural ganglion cyst. A 70-year-old man with subacute bilateral lower extremity numbness, muscle weakness, and gait disturbance presented to our hospital. Magnetic resonance (MR) images showed a cystic lesion which compresses the left dorsolateral intraspinal space of T2-3. During surgery, a ganglion cyst was found without adhering to the periphery of the epidural space. The capsule and contents were removed. He showed postoperative improvement in activities of daily living. A postoperative pathological diagnosis of ganglion cyst was made. The development mechanism of thoracic interdural ganglion cysts is unknown. To our knowledge, this is the first report of this disease. Surgery improved symptoms of a patient with myelopathy caused by thoracic interdural ganglion cysts. This must be considered as one of the cystic lesions presenting with myelopathy.Adhesive arachnoiditis (AA) is a chronic inflammation inside the dura and remains one of the most challenging diseases. We describe a case of treatment-resistant extensive AA that offers insight into surgical treatment selection. The patient had a 2-year history of progressive spastic gait and was diagnosed with syringomyelia caused by extensive AA. Although syringe-subarachnoid and subarachnoid-subarachnoid shunting resulted in recurrence within a short period, syringo- peritoneal shunting improved the symptoms and there was no recurrence. This case suggests that syringo-peritoneal cerebrospinal fluid (CSF) shunt drainage, which has previously been considered a further step, may be a first-surgery option for extensive AA.Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor, and develops infrequently in the central nervous system. To our knowledge, this is the first case of EHE of the spinal cord. An 85-year-old man presented with about 6-month progressive myelopathy. Magnetic resonance imaging (MRI) demonstrated an oval-shaped intradural extramedullary mass at T10 level with extensive intramedullary edema. A reddish tumor was removed via a total laminectomy of T9-T10. Histologically, the tumor cells with nuclear atypia and active mitoses were immunopositive for vascular tumor markers, and formed a lobular architecture associated with capillary-sized vessels lined with edematous endothelial cells. Although very rare, EHE should be considered in the differential diagnosis of a spinal intradural extramedullary tumor.
