Methods: An animal model was developed to permit daily monitoring of neovascularization of the flap with autoradiography, tissue transparent technique, gross observation and histological examination. Results: The revascularization of the flap was chiefly raised from the surrounding tissues. The pedicles of 334 cross finger flaps of the patients were successfully divided from 1 to 5 d after operations, averagely 3.3 d. All of the cases showed satisfatory results according to a follow up survey of 3 to 72 mon. The results further proved that the revascularization of the cross finger flaps had accomplished within 3 d. Conclusions: It suggests that the division of a cross finger flap can be carried out between the 3rd and 5th day after operation with a high degree of safety.展开更多
