The most common cause of poor outcome following lumbar disc surgery is recurrent herniation. Recurrence has been noted in 5% to 15% patients with surgically treated primary There have many studies designed determine the risk factors for In this study, we retrospectively analysed influence degeneration, endplate changes, surgical technique, and patient's clinical characteristics on herniation.Patients who underwent single-level L4-L5 discectomy were reoperated herniation reviewed. All these...
OBJECTIVE Tobacco smoking is among the factors known to significantly augment risk of untreated intracranial aneurysm (IA) growth and rupture. Smoking appears have a variable effect on different endovascular treatment modalities. The impact safety, efficacy, outcomes Woven EndoBridge (WEB) device use for wide-neck IAs has not been evaluated. This study aimed investigate WEB devices by status. METHODS A retrospective multicenter analysis was conducted data patients from 36 sites worldwide...
Abstract The Woven EndoBridge (WEB) device is primarily used for treating wide-neck intracranial bifurcation aneurysms under 10 mm. Limited data exists on its efficacy large aneurysms. We aim to assess angiographic and clinical outcomes of the WEB in versus small . conducted a retrospective review WorldWide Consortium database, from 2011 2022, across 30 academic institutions globally. Propensity score matching (PSM) was employed compare baseline characteristics. A total 898 patients were...
Nine patients treated surgically for lumbar spinal synovial cyst were reviewed. Four had synovial, two ganglion, one posterior longitudinal ligament, and ligamentum flavum cyst. Synovial cysts a single layer of epithelial cells in the inner with continuity facet joint. Ganglion no joint lining was present absent case. Posterior ligament lining. Magnetic resonance imaging showed better than computed tomography. All nerve root compression or canal narrowing. One patient suffered recurrence 1...
Purpose Long-term compaction, compression, migration, and recurrence rates of the WovenEndoBridge devices remain unknown. The purpose this study was to detect these safety profiles within 7 years period. Materials methods Eighty-three aneurysms 79 patients treated with device were retrospectively evaluated using an occlusion scale (e.g. complete occlusion, neck remnant, aneurysm remnant) on angiography images. Results residual observed in 11 (13%) aneurysms. mean median diameters recurrent 6...
The combination of anterior and posterior instrumentation provides the most stable repair for burst fractures thoracolumbar spine. However, use both approaches on a trauma patient may increase morbidity. Stabilization three columns through only one approach can provide an effective outcome. We treated eight patients with fracture involving thoracic or lumbar vertebrae by application stabilization instruments approach. desired was obtained in all patients. advantages are absence risks...
AIm:We aimed to show the significance of anterior pontine membrane as a determining structure between subdural and subarachnoid space in clival region.mAterIAl methOds: Five adult cadaver heads five cerebral hemispheres were used.The skull vault hemipheres removed by sectioning through pontomesencephalic junction.Five other but arachnoid was protected side dura mater dissected.In another specimen, dural porus abducens nerve sectioned for histological evaluation.Three cases hematoma at clivus...
Decreasing size of disc material that has herniated, whether "contained" or "protruded" previously been described and sometimes this can be so complete residual is barely visible. In a retrospective clinical survey, from among almost 2180 consecutive patients admitted during 1994 - 2002 with low back pain; due to our follow-up ratios high price the magnetic resonance imaging (MRI), only 42 lumbar protrusion could found who had two MRI scans obtained at least five weeks apart. Among these, 4...
<i>Objective:</i> To report a case of pituitary adenoma apoplexy presenting with bilateral proptosis and third nerve palsy that developed after cardiovascular surgery. <i>Clinical Presentation Intervention:</i> A 45-year-old man coronary artery bypass grafting operation. macroadenoma extension into the sphenoid sinus cavernous involvement was resected on computed tomography scan by microscopic transsphenoidal procedure. Third improved partially first postoperative day...
Vacuum disc phenomenon is seen frequently with degenerative disease and characterized by the collection of gas in space. Although accumulation within space does not have clinical significance, symptoms may develop when occurring spinal canal. We present a 60-year-old female patient low back left leg pain for 3 months before admission to our clinic. Straight raise test was 50 degrees leg. Magnetic resonance imaging showed narrowing L5-S1 vacuum hypointense cystic mass T1 T2-weighted images....
Despite the numerous studies evaluating occlusion rates of aneurysms following WEB embolization, there are limited identifying predictors occlusion. Our purpose was to identify aneurysm and need for retreatment.
OBJECTIVE Cellular schwannomas (CS) are rare in the cranial space. This report is first of a patient with greater superficial petrosal nerve CS presenting abducens palsy and xerophthalmia. CLINICAL PRESENTATION A 16-year-old female presented 1-month history diplopia. Neurological examination was normal except for presence right palsy. Schirmer's test revealed decreased tear secretion eye. Computed tomography magnetic resonance imaging showed mass petrous apex. It thought that schwannoma our...
Abstract The aim of this study was to show morphological sulcal variations the pars triangularis inferior frontal gyrus and provide a clearer description anterior sylvian point. Thirty‐six hemispheres 18 adult cadavers were studied. harvested by classical autopsy method fixed in 10% formalin solution for three weeks. In six hemispheres, arteries veins filled with colored silicone. proximal distal segments fissure, perpendicular distance both point rolandic insular cortex distances between...
There is no study on the role of three-dimensional compressed sensing time flight MR angiography (3D-CS-TOF) in management WEB device. We evaluated efficacy 3-tesla 3D-CS-TOF for and follow-up device implantations.Seventy-three aneurysms 69 patients treated with were retrospectively examined. Morphological parameters embolization results assessed compared 3D-CS-TOF, CTA, DSA images.Occluded, neck remnant, recurrent observed 61 (83.6%), 7 (9.6%), 5 (6.8%) aneurysms, respectively. Inter-...
Background: Syringomyelia is a fl uid-fi lled tubular cavity within the spinal cord.The exact pathophysiology of syringomyelia remains complex and uncertain.Material: We present case resolution cervical after disc operation in follow-up time 6 months.Conclusion: Restoration cerebrospinal uid ow dynamics between syrinx subarachnoid space via removing main pathology such as our reported case, may contribute (Fig. 3, Ref. 22).
Oligodendroglioma, usually found in the cerebral hemispheres may invade ventricles, however primary intraventricular oligodendroglioma is quite uncommon with only a limited number of cases reported literature. A 39-year-old woman harbouring left lateral ventricle was treated by subtotal removal tumour through frontal transcortical transventricular approach. The clinical, radiological and surgical details case are presented correlation current data on oligodendrogliomas. Benefits...
OBJECTIVE The Woven EndoBridge (WEB) device was approved to treat wide-necked bifurcation aneurysms. is designed as an intrasaccular flow disruptor covering aneurysm widths up 10 mm. Although prior studies combined all sizes, it known that aneurysms behave differently in response endovascular treatment based on their size. Therefore, the authors’ objective identify ideal middle cerebral artery (MCA) width and neck sizes most suitable for WEB treatment. METHODS WorldWideWEB consortium a large...
ABSTRACT Purpose We aimed to characterize and further understand CSF circulation outflow of rabbits. To our knowledge, there is no research on contrast material–enhanced MR cisternography ( CE ‐MRC) with T1 T2 mapping in the rabbit model using a clinical 3‐T unit without stereotaxic frame. Materials Methods Twenty‐one rabbits were included study. The ‐MRC exams T1/T2 mappings categorized into approximate time points based an intention‐to‐scan approach: precontrast, less than 4 h after...
