Comparing the adult submammalian brain with the human embryonic brain, some patterns of venous drainage are quite similar. The veins lying on the lateral surface of the brain in sub-mammals resemble those of the human embryo. In addition, the new longitudinal venous anastomosis ventral to the brain vesicles occurring late in human embryonic development seems to be similar to the late appearance of the basal vein and the ventral brain stem venous plexus found in adult mammals including man. The evolution of the new structures of the brain vesicles throughout the vertebrate series may have an induction role on the appearance of the cranial venous system. This part of the article series focuses on the evolution of the lateral-ventral venous system of the five brain vesicles. Nevertheless, the limitation of this article is due in part to the paucity of circumstantial papers and different names used for the veins.

Many classifications of the cerebral venous system are found in the literature but they are seldom based on phylogenic study. Among vertebrates, venous drainage of the brain vesicles differs depending on the species. Due to the variability, poorly descriptive articles, and many different names used for the veins, the comparative study of the cranial venous system can hardly be performed in detail. The cranial venous system in vertebrates can be divided into three systems based on the evolution of the meninges and structures of the brain vesicles: the dorsal, lateral-ventral and ventricular systems. This study proposes a new classification of the venous drainage of brain vesicles using knowledge from a comparative study of vertebrates and focusing on the dorsal venous system. We found that the venous drainage of the neopallium and neocerebellum is involved with this system which may be a recent acquisition of cranial venous evolution.

Many malignancies, like prostate, colon, and breast cancer, metastasize throughBatson’s plexus (vertebral venous plexus). Although lung cancer is one of the mostcommon cancers in the United States, its spread through Batson’s plexus is consideredextremely rare. We report a 76-year-old woman with adenocarcinoma of the lung whohad metastasis affecting multiple contiguous vertebral bodies likely due to disseminationthrough Batson’s plexus of veins. This plexus is a component of the cerebrospinalvenous system (CSVS) consisting of the cranial venous system and the vertebralvenous plexus (Batson’s plexus). The CSVS is a valveless network of veins which areimportant in the venous drainage of the brain and spine. However, this venous networkprovides an easy channel for the dissemination of infections and malignant cells.

Adjacent to the arterial circle of Willis at the base of the brain, there is an anastomotic circle of veins linking the right and left halves of the cerebral deep venous system. This venous circle is formed by anterior and posterior transverse anastomotic channels (the anterior and posterior communicating veins), and paramedian longitudinal vessels (the basal veins of Rosenthal). This collateral venous network has received considerably less attention than its arterial counterpart, but is its functional homologue. Although inconstant, it can be seen readily with current neuroimaging techniques including three-dimensional digital subtraction venographic phase 3D arteriography (3D-DSV) and CT venography (CTV). The venous circle represents a route of contralateral venous drainage that may become important, particularly when segments of the basal vein are absent (with or without complex DVA), or in high flow states including arteriovenous shunts that access the deep venous system. We review the gross anatomy and provide examples of the radiologic imaging of this venous circle.

Ontogenetically, the ventricular venous system may develop in order to drain the gray matter (cells of the mantle layer of the neural tube) which migrates dorsally. On primitive brain vesicles of submammals especially fish, amphibian and reptile, the ventricular venous system is the major venous collector located on the mid-dorsal surface, in between the meningeal layers comparable to the subarachnoid space in mammals. The ventricular venous system functions as a major drainage system for the brain vesicles in these submammals but its role decreases when the other two venous systems develop. Concerning the route of venous exit from the brain vesicles, we found that it resembles the spinal cord but could not be found all the way along the brain vesicles.

Brain Patterning

In vertebrates (deuterostomes), brain patterning depends on signals from adjacent tissues. For example, holoprosencephaly, the most common brain anomaly in humans, results from defects in signaling between the embryonic prechordal plate (consisting of the dorsal foregut endoderm and mesoderm) and the brain. I have examined whether a similar mechanism of brain development occurs in the protostome Drosophila, and find that the foregut and mesoderm act to pattern the fly embryonic brain. When the foregut and mesoderm of Drosophila are ablated, brain patterning is disrupted. The loss of Hedgehog expressed in the foregut appears to mediate this effect, as it does in vertebrates. One mechanism whereby these defects occur is a disruption of normal apoptosis in the brain. These data argue that the last common ancestor of protostomes and deuterostomes had a prototype of the brains present in modern animals, and also suggest that the foregut and mesoderm contributed to the patterning of this ‘proto-brain’. They also argue that the foreguts of protostomes and deuterostomes, which have traditionally been assigned to different germ layers, are actually homologous.

Pulmonary sequestrations are congenital masses of aberrant, nonfunctioning pulmonary tissue that usually do not connect with the bronchial tree and derive their arterial blood supply from systemic vessels, most often the distal thoracic or upper abdominal aorta. The majority of sequestrations are intralobar and contained within the visceral pleura of the normal lung; these usually have their venous drainage to the pulmonary venous system. Extralobar sequestrations have a separate pleural covering and usually drain to systemic veins or the portal venous system.1-3 Patients most often come to clinical attention with repeated respiratory infections.2 The sequestered segment is usually visualized radiographically as a nonaerated opacity at the medial lung base, more often left-sided.

AbstractGrafting embryonic brain tissue into the brain of patients with visual field loss due to cerebral lesions may become a method to restore visual function. This method is not without risk, however, and will only be considered in cases of complete blindness after bilateral occipital lesions, when other, risk-free neuropsychological methods fail.
