The blood supply of the vertebral column and spinal cord in man


Book Description

This book was written in an attempt to fill a serious gap in medieal literature. A coneise anatomieal text, incorporating an atlas of the vaseular anatomy of the vertebral column and spinal cord, it has been designed to suit the needs of ort ho pedie surgeons, neurosurgeons, and neurologists. We also fee! that this work will he!p give direetion to further studies on the morphology and physiology of spinal eirculation. The book begins with a diseussion of the origins of the arteries whieh supply the vertebral eolumn. It eontinues with adescription of the various regions of the spine, the eervieal, thoraeie, and lumbar, and of the arteries which supply the meninges and spinal cord, the veins of the verte bral column, and venous and arterial distribution within the spinal cord. Anatomie studies of the eireulation both in bones and in the spinal cord require the use of teehniques whieh are erude and time consuming. Essential to sueeess is aecess to fresh postmortem human bodies, so that injeetions into the vaseular systems may be attempted before any disseetion has been made in the course of the routine pathologie examination. Permission to pursue these partieular anatomie studies eannot be obtained as a matter of routine. Beeause of the restrieted availability of speeimens therefore, only random sam pIes can be obtained.




The Spinal Cord


Book Description

Many hundreds of thousands suffer spinal cord injuries leading to loss of sensation and motor function in the body below the point of injury. Spinal cord research has made some significant strides towards new treatment methods, and is a focus of many laboratories worldwide. In addition, research on the involvement of the spinal cord in pain and the abilities of nervous tissue in the spine to regenerate has increasingly been on the forefront of biomedical research in the past years. The Spinal Cord, a collaboration with the Christopher and Dana Reeve Foundation, is the first comprehensive book on the anatomy of the mammalian spinal cord. Tens of thousands of articles and dozens of books are published on this subject each year, and a great deal of experimental work has been carried out on the rat spinal cord. Despite this, there is no comprehensive and authoritative atlas of the mammalian spinal cord. Almost all of the fine details of spinal cord anatomy must be searched for in journal articles on particular subjects. This book addresses this need by providing both a comprehensive reference on the mammalian spinal cord and a comparative atlas of both rat and mouse spinal cords in one convenient source. The book provides a descriptive survey of the details of mammalian spinal cord anatomy, focusing on the rat with many illustrations from the leading experts in the field and atlases of the rat and the mouse spinal cord. The rat and mouse spinal cord atlas chapters include photographs of Nissl stained transverse sections from each of the spinal cord segments (obtained from a single unfixed spinal cord), detailed diagrams of each of the spinal cord segments pictured, delineating the laminae of Rexed and all other significant neuronal groupings at each level and photographs of additional sections displaying markers such as acetylcholinesterase (AChE), calbindin, calretinin, choline acetlytransferase, neurofilament protein (SMI 32), enkephalin, calcitonin gene-related peptide (CGRP), and neuronal nuclear protein (NeuN). The text provides a detailed account of the anatomy of the mammalian spinal cord and surrounding musculoskeletal elements The major topics addressed are: development of the spinal cord; the gross anatomy of the spinal cord and its meninges; spinal nerves, nerve roots, and dorsal root ganglia; the vertebral column, vertebral joints, and vertebral muscles; blood supply of the spinal cord; cytoarchitecture and chemoarchitecture of the spinal gray matter; musculotopic anatomy of motoneuron groups; tracts connecting the brain and spinal cord; spinospinal pathways; sympathetic and parasympathetic elements in the spinal cord; neuronal groups and pathways that control micturition; the anatomy of spinal cord injury in experimental animals The atlas of the rat and mouse spinal cord has the following features: Photographs of Nissl stained transverse sections from each of 34 spinal segments for the rat and mouse; Detailed diagrams of each of the 34 spinal segments for rat and mouse, delineating the laminae of Rexed and all other significant neuronal groupings at each level. ; Alongside each of the 34 Nissl stained segments, there are additional sections displaying markers such as acetylcholinesterase, calbindin, calretinin, choline acetlytransferase, neurofilament protein (SMI 32), and neuronal nuclear protein (NeuN) All the major motoneuron clusters are identified in relation to the individual muscles or muscle groups they supply

The Vertebral Artery


Book Description

Our common interest in surgery of the vertebral artery was born in 1976, when as residents in the same hospital, we attended an attempt by two senior surgeons to treat an aneurysm of the vertebral artery at the C 3 level. Long discussions had preceded this unsuccessful trial, to decide if surgery was indicated and to choose the surgical route. Finally a direct lateral approach was performed, but access was difficult and correct treatment was impossible, resulting in only partial reduction of the aneurysmal pouch. Following this experience, we decided to seek a regular and well defined approach for exposition of the vertebral artery. Review of the literature indicated some surgical attempts, but the descriptions did not give the impression of safety and reproducibility. No landmark on the described surgical route appeared sufficiently reliable. Henry's anatomical work (1917) gave the only accurate description on vertebral artery anatomy, and it became the basis for our work. When the same patient was referred again one year later, after a new stroke in the vertebro-basilar system, we had behind us repetitive experience on cadavers of an original approach to the distal vertebral artery.




Spinal Cord Blood Supply


Book Description

The lifeline of our spinal cord is a complex network of arteries and veins. The main players are the vertebral arteries, supplying blood from the brain. They branch off to form the anterior and posterior spinal arteries, running along the front and back of the cord. These arteries are crucial, but not alone. Segmental arteries, branching from various arteries along the spine, provide additional blood flow. They pierce the spinal canal and connect with the radicular arteries, supplying blood to specific nerve roots and the cord itself. This intricate system ensures every part of the spinal cord receives the oxygen and nutrients it needs to function. Life stages can impact this delicate network. In the developing fetus, the blood supply is more vulnerable. Certain birth defects may disrupt blood flow, leading to potential neurological problems. As we age, the blood vessels supplying the cord can naturally narrow, increasing the risk of spinal cord ischemia (reduced blood flow). This can cause pain, weakness, or even paralysis. Maintaining a healthy lifestyle is key. Regular exercise promotes good circulation throughout the body, including the spinal cord. Early detection and treatment of conditions like high blood pressure or diabetes can help prevent complications with blood flow. By understanding the intricate dance of the spinal cord's blood supply across our lifespan, we can take steps to safeguard this vital pathway.




Surgical Management of Aortic Pathology


Book Description

This book follows the concept of perceiving the entire aorta as one functional organ assuming that all individual pathologies and local interventional procedures affect the up- and downstream segments with consequences for complications and disease progression. Thus any preventive or surgical strategy must recognize the aortic disease in its entirety. The book intends to cover the full spectrum of aortic pathologies, mechanisms and functional interplay. The latest available diagnostic tools and options for surgical treatment are presented by the foremost experts in their field in state-of-the-art reviews. The reader is provided with the most current and comprehensive insight into all fundamental and clinical aspects of aortic disease. All chapters are carefully complemented with figures and illustrations.




Vascular Anatomy of the Spinal Cord


Book Description

The idea for this treatise on the radiological anatomy of superficial and deep spinal cord vasculature evolved from daily routine neuroradiological work. This was also the reason for subdividing the monograph into a postmortem anatomical and a clinical part. The actual importance of a clear conception of radio anatomic fundamentals was made clear by many clinical conferences with neurologists, neurosurgeons and orthopedists, where a lack of knowledge about medullary syndromes of suspected vascular origin became evident. Also among neuroradiologists there is still widespread uncertainty in the interpretation of myelograms and angiographies in such cases. A study of the spinal cord's angioarchitecture is all the more justified and necessary considering the vast number of descriptions of cerebro vascular anatomy and pathology. The clinical challenge posed by patients suffering from partial or complete transverse spinal lesions has grown due to new diagnostic and therapeutic approaches. Myelography using water-soluble contrast media, X-ray computed tomography, magnetic resonance imaging and spinal angiography today allow and require both earlier and topographically and pathogenetically more exact classification of diseases of the spinal cord and its surrounding structures. Due to progress in microneurosurgery and interventional neuroradiology, even intramedullary lesions have become more and more accessible and treatable. Therefore this monograph mainly addresses those concerned with invasive therapeutic techniques and who are familiar with the interpretation of radio anatomic findings. A comprehensive description of medullary vascular syndromes would be beyond the scope of this treatise.
