M any attempts to visualize the vertebrobasilar system were made before 1959 when Pygott and Hutton described cerebral arteriography by direct percutaneous brachial injection using a catheter. 10, 27, 30, 34, 35, 40, 44, 46, 50, 52–54 The accessibility of the brachial artery, the simplicity of technique, the useful information obtained, and the relative freedom of complications justify the procedure and have promoted its popularity. Clinical Material The records of 1000 patients undergoing brachial arteriography at the Baptist Memorial Hospital, Memphis

, postinfectious hydrocephalus, and hydrocephalus related to Chiari malformation Type I and Dandy-Walker malformation. 20 , 22 , 33 , 36 The variability of the method's success rate, depending on the underlying pathology, has led to the establishment of corresponding indications of various strengths. However, many experts continue to propose different strategies, depending on individual experience and based on the fact that ETV is considered conceptually preferable to VP shunt placement, due to the avoidance of lifetime shunt dependency and associated complications, such as

complications. Endoscopic optics, although improving, can limit 3D image representation and provide imperfect color representation. Tissues of similar color and structure are difficult to differentiate, such as nerve roots and the ligamentum flavum. Surgeons mistaking these structures could encounter intraoperative complications such as dural tears or nerve root injury. Recent developments in tubular retractors, which can reduce the need for thoracoscope or endoscope use, permit 3D visualization through loupe magnification and/or the operating microscope. However, these

I ndividuals who have sustained a traumatic SCI are highly susceptible to physiological disturbances and medical complications that can prolong their hospitalization and impair their recovery. 3 , 18 , 21 Knowledge of the types, frequency, and severity of specific complications and their time of occurrence after SCI can aid health care workers in their detection and prevention. Such information can also inform the choice of new therapies for SCI. For example, knowledge of a high probability of developing pneumonia within the first 2 weeks after SCI

M esial temporal lobe epilepsy is usually resistant to medical management; 8 for those resistant cases, surgical intervention has been proven to be effective. 20 , 25 The aim of surgery is resection of the mesial structures of the temporal lobe with minimal complications and no deaths. Although several studies of MTLE surgery indicate that seizures are resolved for as many as 75%–90% of adequately chosen candidates, 12 , 14 , 19 , 25 misconceptions and stigmas surrounding epilepsy surgery prevent referral of some patients for early treatment. 4

L eptomeningeal metastases (LM) have become increasingly common as anticancer therapies become more effective. 6, 7, 9, 35, 38 Approximately 5% of all patients with solid tumors ultimately develop LM, a metastatic central nervous system (CNS) complication with profound implications for the affected patient. The average survival time following a diagnosis of LM is 4 to 6 months; however, some groups of patients, such as those with breast or hematological cancers, may have considerably longer survival times. Notwithstanding the limited life expectancy of

V entriculostomy , or external ventricular drainage, is among the most common procedures in neurosurgery practice. However, it is not exempt from complications. 6 , 7 Since its first description, it has been improved with several technical advances and safer protocols. 5 , 8 Additionally, complications from the procedure have been addressed in several papers, including reports on infection 2 , 4 and misplacement 3 , 9 as the most important. Despite the better understanding we have about external ventricular drains (EVDs) and the technical advances

T here has been much focus on improving the quality of health care by limiting complications, hospital-acquired conditions, and other provider-preventable complications, as this would be beneficial to patients, providers, and payers. Pay-for-performance measures seek to improve the quality of health care by rewarding practitioners for achieving better patient outcomes. 15 This system assumes that patient outcomes can be favorably changed by practitioner practices in every situation or that complications are all avoidable. Preexisting comorbidities have

E ndoscopic third ventriculostomy (ETV) is an established therapeutic alternative to conventional shunt surgery for patients with noncommunicating hydrocephalus. 22 Neuroendoscopy has many advantages, including speed, simplicity, avoidance of implants, and avoidance of brain retraction or dissection. However, a variety of perioperative complications have been reported in ETV, attributed mostly to the unique surgical technique, which causes alterations in cerebral flow dynamics and injuries to vital brain areas. Previously reported complication rates range

T he prevalence of positional plagiocephaly in infants has grown significantly with the “Back to Sleep” campaign. The incidence of this deformity is estimated to have increased from 0.3% prior to the campaign to 8.2% or even higher today, depending on the sensitivity of criteria used to establish the diagnosis. 11 , 13 , 14 , 19 , 33 Given this increased prevalence, careful examination of treatment strategies and their potential complications is important. It has been determined that about 85% of cranial growth takes place during the 1st year of
