The Exploratory Development With Color Doppler Ultrasound Image Formation Technology On The Toe-to-thumb Reconstruction

Objective: To get the normal image data and the rate of the variation about the health adult's part of blood vessels of the hands and feet(relevant to toe-to-thumb reconstruction), and to know if there was any damage or absence in the vascular systems of either the donor or the recipient site, and to know the condition of the courser, the size of caliber of the vessels with Color Doppler image formation technology, so as to provide suitable operation scheme before the toe-to-thumb reconstruction, shorten operation time, decrease wounds in either the donor or the recipient site and raise reconstruction survival rate.Methods: The subjects were divided into healthy adult group and the researchgroup for toe-to-thumb and underwent the Color Doppler checks .The healthy group consisted of 40 healthy adult students, with both their hands and feet checked by Color Doppler. The checks were performed for the donor site's conditions of the dorsalis pedis artery, the first dorsal metatarsal artery and the branch of toe web, the great saphenous vein and the dorsum pedis vein, and recipient site's condition of radial artery and cephalic vein's courser, the size of caliber, to obtain part of the healthy adult's blood vessel (relevant to reconstruction) image data of both of hands and feet by means of Color Doppler. In the research group, 36 patients were selected with single thumb coloboma intend to toe-to-thumb reconstruction. Before the operation, colour Doppler was used to examine the conditions of the opposite side of donor site's artery, as for the patients with high risks(Gilbert IIImodel and F model in toe web) in the opposite side foot, the vessels of the same side foot were also examined. For those patients free from high risk in the opposite side foot, the second opposite side toe was to be transplanted, if the opposite side foot was of high risk mode, the same side toe was to be transplanted. If both feet were of high risk mode, the second opposite side toe was to be transplanted, two sets of blood-supply systems...
