“…If major lymph trunks are obstructed, lymph enters the bloodstream through these lymphatic-venous anastomoses, and clinical signs referable to lymphatic obstruction generally do not occur [Blalock et al, 1937;Threefoot, Pearson, Cabrera-Gil and Bradburn, 1967]. However, some authors have been able to impede the entry of lymph into the bloodstream, and have suggested that this may cause important alterations in structure and function [Blalock et al, 1937;Yoffey and Courtice, 1956;Csillik and F6ldi, 1967;Threefoot, Pearson, Cabrera-Gil and Bradburn, 1967]. This may be of particular importance during a period of local lymphatic obstruction in a transplanted organ [Malek, 1967].…”
