PURPOSE: The artery of Adamkiewicz (AKA) provides the major blood supply to the anterior thoracolumbar spinal cord and iatrogenic injury or inadequate reconstruction of this vessel during vascular and endovascular surgery can result in postoperative neurological deficit due to spinal cord ischemia. The aim of this study was to provide comprehensive data on the prevalence and anatomical characteristics of the AKA. METHODS: An extensive search was conducted through the major electronic databases to identify eligible articles. Data extracted included study type, prevalence of the AKA, gender, number of AKA per patient, laterality, origin based on vertebral level, side of origin, morphometric data, and ethnicity subgroups. RESULTS: A total of 60 studies (n = 5437 subjects) were included in the meta-analysis. Our main findings revealed that the AKA was present in 84.6% of the population, and patients most frequently had a single AKA (87.4%) on the left side (76.6%) originating between T8 and L1 (89%). CONCLUSION: As an AKA is present in the majority of the population, caution should be taken during vascular and endovascular surgical procedures to avoid injury or ensure proper reconstruction. All surgeons operating in the thoracolumbar spinal cord should have a thorough understanding of the anatomical characteristics and surgical implications of an AKA.

The general microscopic characteristics of nerves are described in several textbooks of histology, but the specific microanatomies of most nerves that can be blocked by anesthesiologists are usually less well known. Our objective was to evaluate the 3D reconstruction of nerve fascicles from optical projection tomography images (OPT) and the ability to undertake an internal navigation exploring the morphology in detail, more specifically the fascicular interconnections. Median and lingual nerve samples were obtained from five euthanized piglets. OPT images of the samples were acquired and 3D reconstruction was performed. The OPT technique revealed the inner structure of the nerves at high resolution, including large and small fascicles, perineurium, interfascicular tissue, and epineurium. The fascicles were loosely packed inside the median nerve and more densely so in the lingual nerve. Analysis of the 3D models demonstrated that the nerve fascicles can show six general spatial patterns. Fascicular interconnections were clearly identified. The 3D reconstruction of nerve fascicles from OPT images opens a new path for research into the microstructure of the inner contents of fascicular nerve groups and their spatial disposition within the nerve including their interconnections. These techniques enable 3D images of partial areas of nerves to be produced and could became an excellent tool for obtaining data concerning the 3D microanatomy of nerves, essential for better interpretation of ultrasound images in clinical practice and thus avoiding possible neurological complications.

This article deals with a recent revision of the terminology of the Sections Central Nervous System (CNS; Systema nervosum centrale) and Peripheral Nervous System (PNS; Systema nervosum periphericum) of the Terminologia Anatomica (TA, 1998) and the Terminologia Histologica (TH, 2008). These sections were extensively updated by the Federative International Programme for Anatomical Terminology (FIPAT) Working Group Neuroanatomy of the International Federation of Associations of Anatomists (IFAA). After extensive discussions by FIPAT, and consultation with the IFAA Member Societies, these parts were merged to form a Terminologia Neuroanatomica (TNA). After validation at the IFAA Executive Meeting, September 22, 2016, the TNA has been placed on the open part of the FIPAT website (http://FIPAT.library.dal.ca) as the official FIPAT Terminology. This article outlines the major differences between the TNA and the TA. Clin. Anat. 30:145-155, 2017. © 2016 Wiley Periodicals, Inc.

BACKGROUND: The relationship between the recurrent laryngeal nerve (RLN) and inferior thyroid artery (ITA) is highly variable and traceable back to embryological life. METHODS: Comprehensive database searches were conducted, followed by judgment of eligibility, assessment, and extraction of data concerning the RLN/ITA relationship. The data were pooled into a meta-analysis and subjected to sex, side-based, geographic origin of study, and study modality subgroup analyses. RESULTS: Seventy-nine studies (n = 14,269 nerves) reported data on the relationship of the RLN to the ITA. The left versus right-sided comparison revealed stark differences: RLNs were predominantly posterior (62.6% vs 37.0%) and anterior (17.2% vs 37.1%) on the left and right sides, respectively. CONCLUSION: Symmetry of neurovascular relationships should not be assumed. Extra care should be taken during procedures on the right side, because the nerves are significantly more likely to present in patterns (anterior and between) associated with greater risk of iatrogenic injury. © 2016 Wiley Periodicals, Inc.

OBJECTIVE The foramen arcuale (FA) is a bony bridge located over the vertebral artery on the posterior arch of the atlas. The presence of an FA can pose a risk during neurosurgery by providing a false impression of a broader posterior arch. The aim of this study was to provide the most comprehensive investigation on the prevalence of the FA and its clinically important anatomical features. METHODS Major electronic databases were searched to identify all studies that reported relevant data on the FA and the data were pooled into a meta-analysis. RESULTS A total of 127 studies (involving 55,985 subjects) were included. The overall pooled prevalence of a complete FA was 9.1% (95% CI 8.2%-10.1%) versus an incomplete FA, which was 13.6% (95% CI 11.2%-16.2%). The complete FA was found to be most prevalent in North Americans (11.3%) and Europeans (11.2%), and least prevalent among Asians (7.5%). In males (10.4%) the complete FA was more common than in females (7.3%) but an incomplete FA was more commonly seen in females (18.5%) than in males (16.7%). In the presence of a complete FA, a contralateral FA (complete or incomplete) was found in 53.1% of cases. CONCLUSIONS Surgeons should consider the risk for the presence of an FA prior to procedures on the atlas in each patient according to sex and ethnic group. We suggest preoperative screening with computerized tomography as the gold standard for detecting the presence of an FA.
Standard cutaneous innervation maps show strict midline demarcation. Although authors of these maps accept variability of peripheral nerve distribution or occasionally even the midline overlap of cutaneous nerves, this concept seems to be neglected by many other anatomists. To support the statement that such transmedian overlap exists, we performed an extensive literature search and found ample evidence for all regions (head/neck, thorax/abdomen, back, perineum, and genitalia) that peripheral nerves cross the midline or communicate across the midline. This concept has substantial clinical implications, most notably in anesthesia and perineural tumor spread. This article serves as a springboard for future anatomical, clinical, and experimental research.

Vincent Alexander Bochdalek, Czech anatomist and professor, was one of the pioneers in describing congenital diaphragmatic hernias in newborns. Interestingly, there is very little in the literature and almost nothing in the English literature regarding this important medical figure. A dedicated individual, Bochdalek had great perseverance, which allowed him to surpass obstacles in both his personal life and career. He is recognized for his accurate description of posterior diaphragmatic herniation, for which during his lifetime, there was no treatment. In addition, Bochdalek has multiple eponyms in his honor: ganglion Bochdalecki, Bochdalek's basket, and the valves of Bochdalek. Always steadfast in his beliefs, Bochdalek fought for the creation of anatomy labs in Prague against society pressures. His devoted study of anatomy, especially of congenital diaphragmatic hernias, laid the foundation for the successful surgical correction of this once lethal anomaly.
