Morphologie der Ventrikulocoronaren Anastomosen bei Herzen mit intaktem und pathologisch verändertem Coronargefäßsystem

Abstract

Morphology o/ Ventriculo-Coronary Anastomoses i~ Heartswith Intact and Pathologically Altered Coronary Vessels Summary. With the aid of plastic casts and injected hearts, which were treated by the method of Drahn, a survey was given of the morphology of the ventriculo-coronary anastomoses. In principle we distinguish Thebesian vessels, ventriculo-capillary vessels, ventriculo-venous and ventriculo-arterial communications. The last two types can be summarized as ventriculo-vasal vessels. Besides the elaboration of the morphology the functional importance of ventriculo-coronary anastomoses in the presence of coronary ischemia was pointed out.

How Lymph Is Drained away from the Human Papillary Muscle: Anatomical Conditions

“…The most detailed morphological and pathological data pertain to the arteries [1][2][3][4][5]. The venous drainage of papillary muscles has not been described as a whole in the literature until recently; the in vestigators' attention was focused upon the system of thebesian vein running through the papillary muscles [6][7][8][9], Scanty informations are available concerning the lymphatic bed of papillary muscles [10]. Until recently, the in vestigators were able to visualize the subendo cardial lymphatic network in man and ani mals [11][12][13][14][15]; electron-microscopical studies pertained to the lymphatics situated in the chordae tendineae and the subendocardial layer of animal papillary muscles [ 16,17],…”
