The development of the pulmonary vein in the domestic cat

A review of the literature concerning the pulmonary vein reveals the fact that the various investigators have been divided into two groups according to their method of dkaling with t h i subject. On the one hand the older writers, such as Reisseisen (l), Sommering (a), Zuckerkandl (3) and J. F. Meckel (4) regarded the vein simply as part of the general vascular complex and consequently described its morphology with relation both to other portions of the pulmonary system and to the systemic

The later investigators, as Schmidt (16), His (17) , Born (18), Rose (19) and Fedorow (22) have studied the morphology of the vein as such, without reference to its relation to or possible connection with, the extrapulmonary vascular system. They have thus not defined the proper position of the vein in the vascular complex. The first important contributions were those of Reisseisen (1) and Sommering (2). They established the fact that the bronchial and pulmonary veins communicate freely within the lung and that the bronchial veins empty, either directly or through subordinate branches, into the azygos and hemiazygos veins and thus into the systemic circulation. J. F. Meckel (4) accepted the results of Reisseisen and $ommering, and further noted instances in which the pulmonary veins communicate through large or small radicles with the systemic circulation.
