Language：English Publisher：CAMBRIDGE UNIV PRESS

Background: Inflammatory pseudotumours are mostly seen in the lung, and occasionally in the head and neck region including the sinonasal area. Reported treatment modalities comprise corticosteroid treatment, surgical excision and radiotherapy. The latter option is required because wide surgical resection may be difficult for head and neck lesions, especially in children. However, clinicians should be aware of the risk of late-onset side effects of radiotherapy in children.
Case report: We present a two-year-old girl with a massive inflammatory pseudotumour of the maxillary sinus. Transcatheter arterial embolisation was performed, and the lesion was successfully managed without additional therapy. There was no evidence of recurrence over the next five years.
Conclusion: This is the first report presenting the utility of arterial embolisation for inflammatory pseudotumour.

OBJECTIVE: To examine current determinants of poor outcome after aneurysmal subarachnoid hemorrhage (SAH) when ruptured aneurysms are treated with either microsurgery (clipping) or endovascular treatment (coiling) depending on each patient's characteristics.
METHODS: Between March 2006 and February 2007, 534 patients with SAH were enrolled in the Prospective Registry of Subarachnoid Aneurysms Treatment (PRESAT) project. Patients were treated according to the preference of investigators who were experienced in performing both clipping and coiling. Factors influencing poor outcome (12-month modified Rankin Scale [mRS], 3-6) were determined using multivariate logistic regression analyses.
RESULTS: In this cohort, 32.4% of patients were World Federation of Neurosurgical Societies (WFNS) grade IV-V, and 28.1% had a poor outcome. Clipping was preferably performed for small aneurysms with a wide neck and for middle cerebral artery (MCA) aneurysms, whereas coiling was preferred for larger, internal carotid artery (ICA) and posterior circulation aneurysms. In addition to increasing age, admission WFNS grade IV-V, preadmission aneurysmal rerupture, vasospasm-induced cerebral infarct, pneumonia, sepsis, shunt-dependent hydrocephalus and seizure, postclipping hemorrhagic complications (odds ratio 4.8, 95% confidence interval 1.5-15.3, P < 0.01), and postcoiling ischemic complications (odds ratio 4.4, 95% confidence interval 1.3-15.2, P < 0.05) significantly caused poor outcomes, although the complications did not affect mortality. Type of treatment modality and size and location of aneurysms did not influence outcome.
CONCLUSIONS: Introducing an endovascular treatment option has made aneurysm characteristics less important to outcome, but procedural complications are problematic and should be reduced to improve outcome.

An 84-year-old woman with a history of hypertension and a brain infarction presented with a rare distal anterior choroidal artery (AChoA) aneurysm not associated with moyamoya disease manifesting as sudden onset of headache caused by intraventricular hemorrhage. Digital subtraction angiography revealed a peripheral aneurysm in the left AChoA located distal to the plexal point and steno-occlusive changes of the proximal left middle cerebral artery (MCA) and the left posterior cerebral artery (PCA). Collateral arterial channels to the left MCA and left PCA territories were observed along the left AChoA. No neuroimaging findings were compatible with moyamoya disease. Since the aneurysm did not shrink at 2 months after the onset, endovascular treatment was indicated. Under local anesthesia, a microcatheter was placed into the AChoA proximal to the aneurysm with the aid of a 0.008-inch microguidewire. After a provocation test, three detachable platinum coils were delivered into the aneurysm and the parent artery. Complete obliteration of the aneurysm was achieved without additional neurological sequelae. Successful treatment of a ruptured distal AChoA aneurysm associated with atherosclerotic changes of the intracranial arteries was achieved using a meticulous endovascular technique.

Posterior reversible encephalopathy syndrome (PRES) is a clinico-neuroradiological entity with typical symptoms and symmetric high-signal intensity lesions in the bilateral parieto-occipital lobes on T2-weighted or fluid-attenuated inversion recovery (FLAIR) MRI. We described three patients with PRES of varied etiologies. Patient 1 was a young man with severe hypertension who presented with headache and visual disturbance. Patient 2 had leukemia and was receiving umbilical cord blood cell transplantation with immunosuppressant, and developed PRES with convulsions. Patient 3 was a pregnant woman with renal failure, who repeatedly developed PRES with convulsions. FLAIR and apparent diffusion coefficient mapping were useful in detecting PRES lesions in our patients, although diffusion-weighted imaging and CT scans had limited use in the diagnosis. Adequate and prompt treatment with antihypertensive medication immediately ameliorated the symptoms, with improvement of abnormal MRI findings. In previous reports, delayed diagnosis might have affected the prognosis. Further work on the clinical manifestations of PRES and its therapy is required. (C) 2010 Elsevier Ltd. All rights reserved.

Vascular endothelial growth factor (VEGF) administration has recently been assessed as a therapeutic strategy for ischemic diseases including brain ischemia because of its angiogenic effect. However, VEGF also causes detrimental adverse effects by increasing vascular permeability. This study examined whether plasmid human VEGF (phVEGF) administration induced angiogenic effects in the rat brain ischemia model caused by permanent ligation of both common carotid arteries, and investigated the occurrence of adverse effects. Administration of various doses (0-200 mu g) of phVEGF in the temporal muscle was followed by encephalo-myo-synangiosis. Thirty days after treatment, the numbers and areas of capillaries per field in the extracted brains were analyzed with the National Institutes of Health Image software program. The maximal angiogenic effect occurred with a 100 mu g dose of phVEGF in the numbers and areas of capillaries in the VEGF-treated brains. Histological examination showed no apparent adverse effects in the brain parenchyma even at the highest administration dose (200 mu g) of phVEGF. The maximal angiogenic effect at the optimal dose of phVEGF can be considered under the threshold to cause serious adverse effects in the rat brain.

Rebleeding From a Vertebral Artery Dissecting Aneurysm After Endovascular Internal Trapping: Adverse Effect of Intrathecal Urokinase Injection or Incomplete Occlusion?-Case Report

Kenji Sugiu, Koji Tokunaga, Shigeki Ono, Ayumi Nishida, Isao Date

NEUROLOGIA MEDICO-CHIRURGICA 49 ( 12 ) 597 - 600 2009.12

Language：English Publisher：JAPAN NEUROSURGICAL SOC

A 67-year-old woman suffered rebleeding from a ruptured vertebral artery dissecting aneurysm after endovascular internal trapping. The dissecting aneurysm was initially successfully occluded with the affected vertebral artery using detachable coils. However, rebleeding from the aneurysm occurred on the next day. The rebleeding may have resulted from the thrombolytic effect of urokinase, which was injected intrathecally 3 hours before rebleeding occurred, or the relatively loose coil packing of the aneurysm. This case indicates the potential risk of intrathecal use of thrombolytic agents and the importance of complete tight coil packing of the whole dissected site in the treatment of ruptured vertebral artery dissecting aneurysms.

OBJECTIVE: Carotid endarterectomy with a patch graft (Patch CEA) has been our Standard treatment for patients with carotid artery stenosis, but carotid artery stenting (CAS) has emerged as an alternative. The purpose of this study was to compare the postoperative changes in the configurations and the flow velocities of carotid arteries after CAS or Patch CEA.
METHODS: Thirty-one patients undergoing CAS or Patch CEA were included. The pre- and postoperative shapes of the carotid arteries were evaluated by angiography and ultrasonography. Doppler waveforms were recorded in the middle portion of the common carotid artery and in the internal carotid artery bulb to measure flow velocities, including peak systolic, mean, and end-diastolic velocities.
RESULTS: Eighteen patients were treated by CAS, and Patch CEA was performed for 13 patients. Preoperatively, there were no differences in the degrees of stenosis or the flow velocities between the 2 groups. The averages of the diameters of the postoperative internal carotid artery bulbs were 4.5 mm in the CAS group and 7.0 mm in the Ratch CEA group (P < 0.01). The averages of peak systolic, mean, and end-diastolic velocities measured in the internal carotid artery were 80, 42, and 25 cm/s, respectively, in the CAS group, and were significantly greater than those (53, 28, and 16 cm/s, respectively) in the Patch CEA group (P < 0.01).
CONCLUSION: Significant differences in postoperative morphological and hemodynamic conditions between CAS and Patch CEA were observed. The impact of these differences will be determined by further studies.
