atherosclerosis might affect clinical outcomes after decompressive surgery for cervical compression myelopathy. However, to the best of our knowledge no study evaluating the deleterious effects of CKD and atherosclerosis on such outcomes has previously been reported. The purpose of the present study was thus to examine whether CKD and systemic atherosclerosis affect surgical outcomes after laminoplasty in patients with cervical spondylotic myelopathy (CSM). Methods Patients At our institution, patients with CSM are treated with cervical laminoplasty unless they have

patients with kyphotic alignment of the cervical spine or a large OPLL. However, some patients have had poor clinical outcomes after laminoplasty. Several studies have focused mainly on static factors, such as cervical alignment or the OPLL size, and little is known about the impact of dynamic factors on surgical outcomes. The purpose of this study was to assess the predictive factors associated with poor surgical outcomes, particularly the impact of dynamic factors, after laminoplasty for cervical OPLL.

except for transient hemianopia; the other three patients experienced postoperative permanent neurological deterioration, including memory disturbance and hemianopia. Among the three patients who had undergone a subtotal tumor removal, no neurological deterioration occurred postoperatively. Surgical outcome was graded as satisfactory in eight patients (Cases 1–8) given that the tumors had been totally removed and there was no permanent neurological deterioration. Outcome was unsatisfactory in six patients (Cases 9–14) because either the lesions were not totally removed

of advances in microsurgical techniques and the development of electrophysiological recordings. 7, 10 Many of these reports contain relatively small patient populations, however, and have primarily focused on wrist-level injuries with few observations of injuries at the arm or elbow—forearm level. 18 The purpose of this study was to review retrospectively the cases of 654 patients with ulnar nerve injuries, nerve sheath tumors, and ulnar nerve entrapment neuropathy. Postoperative surgical outcomes were evaluated with respect to the type of lesion (in continuity

, particularly in the elderly. These issues, combined with the fact that CSM may stabilize clinically in a subset of patients without surgery, 11 increases the importance of prospectively determining which patients are most likely to benefit from surgical intervention. Our goal in this manuscript is to evaluate the ability of clinical prognostic factors to predict surgical outcome in CSM. A number of factors have been purported to have an impact on surgical outcome in CSM, including neurophysiological function, age, duration of symptoms, preoperative neurological function

. Photomicrographs showing endothelial cell positivity after immunostaining with Factor VIII (A) and CD34 (B) . Original magnification ×200. The postoperative follow-up periods ranged from 24 months to 11 years (mean 82.4 months). Surgical outcomes and assessment of neurological function are summarized in Table 3 . Postoperative and follow-up MRI showed complete tumor excision and no recurrence in 4 patients. The residual lesion in 1 patient regrew during the follow-up period and caused neurological deterioration. This patient (Case 5) underwent a second operation and the

Recursive partition of variables included in multivariate analysis of patients at high risk for complication. The number of partitions (2) was based on the k-fold cross-validation with the highest R 2 value. Comp. = complication(s). Discussion Key Results The objective of this study was to report surgical outcomes following reoperation for recurrent supratentorial non–skull base meningiomas and identify risk factors for complications

following lumbar spinal surgery. Ho Lee et al. investigated surgical outcomes of LSS patients with or without KOA using the Oswestry Disability Index (ODI) and demonstrated that the presence of preoperative KOA was a poor prognostic factor for surgical outcomes of LSS. 11 However, because they assessed surgical outcomes using a single self-reported health-related quality of life (HRQOL) questionnaire, no definitive conclusions could be drawn. Therefore, by using multiple HRQOL parameters, this study aimed to investigate how the KOA condition affects the surgical outcome

or because of intolerance to the drug. Controversy exists in the neurosurgical literature regarding the effect of preoperative treatment of prolactinomas with bromocriptine on surgical outcome, 6, 7, 12, 35 and this has prompted us to review our experience. Clinical Material and Methods Clinical Aspects The case histories of 55 patients with immunocytochemically confirmed prolactin-secreting pituitary adenomas who were operated on by a transsphenoidal approach between 1981 and 1985 were reviewed. The patients comprised 39 women and 16 men, whose ages

those with the cyst on the surface) should be categorized as a different group within VSs and should be appropriately analyzed and reported separately. 13 It is widely believed that CVSs have less favorable surgical outcomes than SVSs with regard to facial nerve outcomes, surgery-related complications, and mortality. 1 , 5 , 6 , 26 , 29 , 32 On the contrary, recently there have been reports that have shown no significant differences in the surgical outcomes among the 2 cohorts of VSs. 9 , 10 , 25 To our knowledge, currently there is no systematic review in the
