Lymphatic drainage of the UE and breast are closely related in the caudal part of the axilla. SN groups for the UE and breast share connections in 24% of cases, which could explain lymphedema after surgery if damaged. Additional studies are needed to further improve our understanding of the lymphatic drainage of the UE and breast.
Patterns of arterial supply to the atria were studied with respect to the coronary sinus region in 60 human hearts obtained from patients with a negative cardiac history and in 2 hearts with ECG-demonstrated coronary sinus rhythm. The atria, including the interatrial septum, were supplied by the right (40%) or left (30%) or both (30%) sinuatrial arteries which, however, did not reach as far as the posterior margin of the oval fossa and the coronary sinus. The region of the coronary sinus with the Eustachian ridge received direct branches from the trunk of the right (41 %) or left (11 %) coronary artery or both (48 %) in the adjacent part of the coronary sulcus. Possible development of the ‘coronary sinus rhythm’ on the basis of multifocal damage of the sinuatrial arteries is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
