This article is the first of three parts. Several aneurysm classification schemes have been proposed for aneurysms arising from the proximal segment of the internal carotid artery in the vicinity of the anterior clinoid process. We have found these schemes to be either contradicting or overlapping. Our desire to categorize these aneurysms more accurately has been aided by an evolving insight into their intricate anatomy as they relate to the complex region of the skull base. We seek to make possible a more accurate definition of the location of the aneurysm preoperatively, thereby allowing for more accurate selection of the proper treatment modality, as well as the best surgical approach and surgical steps, consequently increasing the safety of the treatment. This article presents a classification system we propose based on our experiences with proximal internal carotid artery aneurysms arising in proximity to the anterior clinoid process. Our system is based on analysis of surgical and anatomic findings, correlation of these findings with the radiologic features, and comparison of these findings with previously reported classifications. We emphasize the unique features of each aneurysm type as we present the surgical techniques required for intraoperative understanding as well as successful and safe clipping of each type. This classification system encompasses aneurysms classified by previous methods.
本文是三个部分中的第一部分。对于前床突附近颈内动脉近端段的动脉瘤,已经提出了几种动脉瘤分类方案。我们发现这些方案要么相互矛盾,要么相互重叠。我们希望更准确地对这些动脉瘤进行分类,这得益于对其复杂解剖结构的不断深入了解,因为它们与颅底的复杂区域有关。我们试图在术前更准确地确定动脉瘤的位置,从而更准确地选择合适的治疗方式,以及最佳的手术方法和手术步骤,从而提高治疗的安全性。本文根据我们在前床突附近发生的颈内动脉近端动脉瘤的经验,提出了一个分类系统。我们的系统基于对外科和解剖发现的分析,这些发现与放射学特征的相关性,以及这些发现与先前报道的分类的比较。我们强调了每种动脉瘤类型的独特特征,同时介绍了术中理解所需的手术技术,以及每种类型的成功安全夹闭。这个分类系统包括以前方法分类的动脉瘤。

A 77-year-old woman with a history of hypertension developed acute onset of aphasia and right hemiplegia and hemisensory loss. She was urgently referred to emergency department. Cerebral multidetector computed tomographic angiography (MD-CTA) revealed an acute ischemic stroke due to the occlusion of the left middle cerebral artery (Figure 1). Since the symptoms started three hours previously, the patient was candidate for mechanical thrombectomy. The patient then performed a selective digital subtraction angiography (DSA) of the left internal carotid artery that confirmed occlusion of the ipsilateral middle cerebral artery (Figure 2) and subsequently successfully performed the endovascular mechanical thrombectomy (Figure 2). Her clinical course has shown neurological symptoms improvement over time. Acute ischemic stroke can be caused by several factors, but the main ones are arterial and cardiac embolism, arterial wall disease or variants(1-4). The National Institutes of Health Stroke Scale (NIHSS) score, is widely used as clinical assessment for neurological deficits related to ischemic stroke(1). MDCTA and Magnetic Resonance Imaging are the two gold standard methods for diagnosis in acute ischemic stroke patients(1-5). Thrombolytic therapy of this pathological state began in the fifties, while the endovascular mechanical thrombectomy was defined as a new standard of care in 2015(1,5,6). This recent technique have added tissue window" to the existing "time window" (5,6). So, nowadays patients with small ischemic core, large penumbra, and good collaterals vessel may benefit from endovascular mechanical thrombectomy(1,5,6); even if they arrive within 6-24 h of stroke onset(5.
一名有高血压病史的77岁女性出现急性失语症、右侧偏瘫和半感觉丧失。她被紧急转诊到急诊科。大脑多探测器计算机断层造影(MD-CTA)显示,由于左大脑中动脉闭塞,急性缺血性中风(图1)。由于症状在三小时前开始,该患者有望接受机械血栓切除术。然后,患者对左颈内动脉进行了选择性数字减影血管造影术(DSA),证实了同侧大脑中动脉的闭塞(图2),随后成功进行了血管内机械血栓切除术(图2。她的临床过程显示,随着时间的推移,神经系统症状有所改善。急性缺血性中风可由多种因素引起,但主要是动脉和心脏栓塞、动脉壁疾病或变异(1-4)。美国国立卫生研究院卒中量表(NIHSS)评分被广泛用作缺血性卒中相关神经功能缺损的临床评估(1)。MDCTA和磁共振成像是诊断急性缺血性脑卒中患者的两种金标准方法(1-5)。这种病理状态的溶栓治疗始于50年代,而血管内机械血栓切除术在2015年被定义为一种新的护理标准(1,5,6)。这项最新技术在现有的“时间窗口”(5,6)的基础上增加了“组织窗口”。因此,如今,具有小缺血核心、大半影和良好侧支血管的患者可能会受益于血管内机械血栓切除术(1,5,6。

surgical exposure to periand intra-Sylvian structures and allows direct access to parasellar structures. Despite its widespread use, the pterional approach presents several limitations: (1) potential postoperative temporal atrophy due to complete temporal muscle dissection; (2) injury to the frontal branch of the facial nerve; and (3) large incision and craniotomy, which may need longer healing time. Over the years, pterional craniotomy has seen many modifications, including extensions (intradural and extradural clinoidectomy, orbit unroofing, etc) and minimally invasive modifications as well. Among the minimally invasive pterional keyhole craniotomies, many have failed to address the limitations associated with the standard pterional craniotomy, and seldom were these approaches standardized. We present a minimally invasive keyhole craniotomy centered on the sphenoid ridge: the extended lateral orbital (XLO) approach (Figure 1). XLO is a novel approach developed to improve the limitations associated with the pterional craniotomy. This review illustrates the anatomic basis of the approach and its limitations and indications.
手术暴露于肛周Sylvian内结构,并允许直接进入鞍旁结构。尽管翼点入路广泛使用,但它存在几个局限性:(1)由于完全颞肌剥离,可能导致术后颞肌萎缩;(2) 面神经额支损伤;以及(3)大切口和开颅手术,这可能需要更长的愈合时间。多年来,翼点开颅术有许多改进,包括扩展(硬膜内和硬膜外床侧切除术、眼眶去顶术等)和微创改进。在微创翼点锁孔开颅术中,许多方法未能解决与标准翼点开颅术相关的局限性,而且这些方法很少标准化。我们提出了一种以蝶嵴为中心的微创锁孔开颅术:扩展外侧眶(XLO)入路(图1)。XLO是一种新的方法,旨在改善翼点开颅术的局限性。这篇综述说明了入路的解剖学基础及其局限性和适应症。

rette smoking remains a significant public health concern. Smoking and secondhand smoke exposure account for approximately 480,000 deaths each year in the United States alone. Among other medical complications, smoking has been established to cause cancer, stroke, coronary artery disease, chronic obstructive pulmonary disease, and increases the risk of developing tuberculosis, rheumatoid arthritis, and pregnancy complications. In addition to numerous health consequences, cigarette smoking gives rise to considerable economic costs, including over $170 billion per year in direct medical expenditures. The burden of smoking-related cardiovascular and respiratory disease is well-characterized and remains a focus in the literature, but mounting evidence points to equivalently impactful effects on the musculoskeletal system. Patients’ tobacco use is of particular interest to spine surgeons, as cigarette smoking inhibits vertebral bone healing, increases rates of infection and reoperation, and leads to poor patientreported outcomes.
吸烟仍然是一个重大的公共卫生问题。仅在美国,每年就有大约48万人死于吸烟和二手烟。在其他医疗并发症中,吸烟已被确定会导致癌症、中风、冠状动脉疾病、慢性阻塞性肺病,并增加患结核病、类风湿关节炎和妊娠并发症的风险。除了许多健康后果外,吸烟还造成相当大的经济成本,包括每年超过1700亿美元的直接医疗支出。与吸烟相关的心血管和呼吸系统疾病的负担已经得到了很好的描述,并且仍然是文献中的焦点,但越来越多的证据表明,吸烟对肌肉骨骼系统也有同样的影响。脊柱外科医生对患者的烟草使用特别感兴趣,因为吸烟会抑制椎体骨愈合,增加感染和再手术率,并导致患者报告的预后不佳。

light interference-based imaging technique that provides real-time, in situ, cross-sectional images of human tissues or biological materials with excellent resolution. It is based on differential reflection or backscattering of light waves with corresponding time delays and variable magnitudes used to generate depth-resolved images—in a sense, analogous to B-mode ultrasonography—except it uses light instead of sound. The image resolution with OCT is not as precise as that seen with confocal or fluorescence microscopy but it is far superior to the resolution obtained with ultrasonography. Ophthalmology was the first field to adopt this technology—the anatomic components of the eye transmit light with minimal optical attenuation and scattering providing high-resolution images of the retina with OCT. In fact, structural damage to the entire optic pathway can be assessed and response to therapy tracked with OCT. OCT also has the ability to penetrate nontransparent tissues extending its applications further. The roots of OCT lie in femtosecond optics—the concept of using echoes of light to see inside biological tissues. Its origins trace back to basic science and physics laboratories—in fact, its application as a clinical modality represents one of the best paradigms of innovative thinking, translational research, and multidisciplinary collaboration, along with industry and governmental support. In 1991, Huang first demonstrated its utility in imaging living tissues providing the first in vitro cross-sectional images of the retina. Shortly thereafter, in 1993, Swanson et al at the Massachusetts Institute of Technology provided the first in vivo human retinal images depicting the retinal nerve fiber layer
光干涉成像技术,提供实时的,原位的,具有优异分辨率的人体组织或生物材料的横断面图像。它基于光波的微分反射或后向散射,具有相应的时间延迟和可变幅度,用于产生深度分辨图像——在某种意义上类似于b型超声——只是它使用光而不是声音。OCT的图像分辨率不如共聚焦显微镜或荧光显微镜精确,但远优于超声成像。眼科是第一个采用这项技术的领域——眼睛的解剖成分以最小的光学衰减和散射传输光,使用OCT提供视网膜的高分辨率图像。事实上,可以评估整个视神经通路的结构损伤,并跟踪OCT对治疗的反应。OCT的根源在于飞秒光学——利用光的回声来观察生物组织内部的概念。它的起源可以追溯到基础科学和物理实验室——事实上,它作为一种临床模式的应用代表了创新思维、转化研究和多学科合作的最佳范例之一,同时得到了行业和政府的支持。1991年,Huang首次展示了其在活体组织成像中的应用,提供了第一张视网膜的体外横切面图像。此后不久,在1993年,麻省理工学院的Swanson等人提供了第一张描绘视网膜神经纤维层的人体视网膜图像

Spinal Hemangioblastomas: Clinical Presentation, Radiology, and Treatment 脊柱成血管细胞瘤:临床表现、放射学和治疗

tion (WHO) grade I benign tumors that occur throughout the neuraxis. Spinal hemangioblastomas (SHs) make up 2% to 15% of all spinal intramedullary tumors. These highly vascular tumors usually arise from the dorsolateral pia mater. Considerable progress has been made in the surgical treatment of SHs since the fi rst report of successful excision by Schultze in 1912. The principles for surgical resection of SHs are similar to those for the arteriovenous malformations (AVMs) and different from the intramedullary glial tumors. Both SH and AVM require a circumferential dissection from the surrounding normal tissue, whereas in contrast to the intramedullary glial tumors, resection of SH and AVM is performed en bloc without internal debulking, because of the highly vascular nature of these tumors. Epidemiology SH is the third most frequently found intramedullary spinal cord tumor, after gliomas and ependymomas. They commonly occur in young adults age 30 to 40 years, with some patients having a positive family history. Hemangioblastomas are more common in the posterior fossa than the spinal cord. SH can arise sporadically (∼60% of cases) or in the context of von Hippel-Lindau (VHL) disease. Sporadic cases are generally in patients who are a decade older than those with VHL disease. Multiple tumors are observed in 60% to 80% of VHL-associated hemangioblastomas, and most are revealed as smaller lesions. In contrast, multifocal tumors comprise only about 3% of sporadic hemangioblastomas.
(世界卫生组织)一级良性肿瘤,发生于整个神经系统。脊髓血管母细胞瘤(SHs)占所有脊髓髓内肿瘤的2%至15%。这些高度血管性肿瘤通常发生在软脑膜背外侧。自1912年Schultze首次报道成功切除SHs以来,SHs的外科治疗已经取得了相当大的进展。SHs手术切除的原则与动静脉畸形(AVMs)的原则相似,但与髓内神经胶质瘤的原则不同。SH和AVM都需要从周围的正常组织中进行周向剥离,而与髓内神经胶质瘤相比,由于这些肿瘤的高度血管性,SH和AVM的切除是在没有内部剥离的情况下整体进行的。流行病学SH是第三常见的髓内脊髓肿瘤,仅次于胶质瘤和室管膜瘤。它们通常发生在30至40岁的年轻人中,有些患者有阳性家族史。血管母细胞瘤在后颅窝比在脊髓更常见。SH可偶尔出现(约60%的病例)或在von Hippel-Lindau(VHL)疾病的背景下出现。散发性病例通常发生在比VHL患者年长十岁的患者身上。在60%至80%的VHL相关血管母细胞瘤中观察到多发性肿瘤,大多数表现为较小的病变。相反,多灶性肿瘤仅占散发性血管母细胞瘤的约3%。

Spinal hemangioblastomas (SHs) make up 2% to 15% of all spinal intramedullary tumors. These highly vascular tumors usually arise from the dorsolateral pia mater. Considerable progress has been made in the surgical treatment of SHs since the fi rst report of successful excision by Schultze in 1912. The principles for surgical resection of SHs are similar to those for the arteriovenous malformations (AVMs) and different from the intramedullary glial tumors. Both SH and AVM require a circumferential dissection from the surrounding normal tissue, whereas in contrast to the intramedullary glial tumors, resection of SH and AVM is performed en bloc without internal debulking, because of the highly vascular nature of these tumors. Epidemiology SH is the third most frequently found intramedullary spinal cord tumor, after gliomas and ependymomas. They commonly occur in young adults age 30 to 40 years, with some patients having a positive family history. Hemangioblastomas are more common in the posterior fossa than the spinal cord. SH can arise sporadically (∼60% of cases) or in the context of von Hippel-Lindau (VHL) disease. Sporadic cases are generally in patients who are a decade older than those with VHL disease. Multiple tumors are observed in 60% to 80% of VHL-associated hemangioblastomas, and most are revealed as smaller lesions. In contrast, multifocal tumors comprise only about 3% of sporadic hemangioblastomas.","PeriodicalId":91465,"journal":{"name":"Contemporary neurosurgery","volume":"41 1","pages":"1 - 5"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/01.CNE.0000558612.20449.66","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43307061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
