Objective: To observe vessels of hand for congenital syndactyly malformation (CSM) in children with contrast-enhanced three-dimensional water selective cartilage scan (CE-3D-WATSc). Methods Twelve children with CSM underwent CE-3D-WATSc before separation surgery of syndactyly were included. The bifurcated positions of common palmar digital arteries, the development and trend of proper palmar digital arteries were observed. The consequences of CE-3D-WATSc and intraoperative observation were compared and analyzed. Results: The common palmar digital arteries of hands in 12 cases were shown with CE-3D-WATSc, of which the bifurcated positions were normal in 10 cases and were slightly elevated to about 1/3 of proximal phalanges in 2 cases, which were completely consistent with the intraoperative observation results.The proper palmar digital arteries were displayed with CE-3D-WATSc in 10 cases, among which 9 were normal development and 1 was small, while not shown in 2 cases. During surgical operation, the proper palmar digital arteries were found in 12 cases, while being filamentous in 2 cases that not shown with CE-3D-WATSc. Conclusion: CE-3D-WATSc has some application values in evaluating vessels of hand for CSM in children before surgical operation.
