متن کاملLymphatic drainage of the heart in the laboratory rat.
We showed in the Sprague Dawley rat that the principal ascending cardiac lymphatic is similar in location to that of man and dog and can be readily visualized by injection of a small amount of T1824 blue dye (Evans) into the apex of the left ventricle. We also showed that it is possible to ligate and thereby obstruct this principal cardiac lymphatic near its entry beneath the left atrial append...
متن کاملThe lymphatic drainage of the parietal pericardium in man.
Parietal pericardial lymphatics were visualized by indirect and direct India ink injections in 35 human cadavers. Studies included examination of cleared specimens under the dissecting microscope and standard light microscopy. The lymphatic vessels of the ventral pericardial surface most often pass along the phrenic nerves cranially to terminate in the anterior right and left and transverse med...
متن کاملPitfalls in Cutaneous Melanoma Lymphatic Drainage.
Sentinel node (SN) biopsy has become standard in staging of cutaneous melanoma. As skin lymphatic drainage is complex, preoperative empirical assessment of SN localization is virtually impossible. Therefore in order to identify all regional lymphatic basins corresponding to a specific primary tumor is mandatory to carry out preoperative lymphoscintigraphy. In this paper we present a clinical ca...
