Aims and objectives
Congenital syndactyly malformation (CSM) is an anomaly where there is fusion of adjacent digits due to failure of separation of developing phalanges during organogenesis.
Proper operation opportunity and methods are crucial for better prognosis,
which need to identify the position and trend of the bifurcated blood vessels before surgery.
This study aimed to analyze the preoperative evaluation value of contrast enhanced three dimensional water selective cartilage scan (CE-3D-WATSc) for CSM in children.
Methods and materials
Twelve patients with clinical diagnosis of CSM(Fig.
1) underwent CE-3D-WATSc before operation by a 3.0-T magnetic resonance imaging(MRI)unit,
who would take the separation surgery of syndactyly were included between May 2014 and April 2017.CE-3D-WATSc was performed to observe the bifurcated positions of common palmar digital arteries,
and the development and trend of proper palmar digital arteries ,
using a three dimensional spoiled gradient echo sequence with fat saturation.
Subsequently the patients underwent operation according to the MRI manifestations.The consequences of CE-3D-WATSc and intraoperative observation were...
Results
In 12 cases the common palmar digital arteries of hands were shown by CE-3D-WATSc,
of which the bifurcated positions were normal in 10 cases and were slightly elevated to about one third of proximal phalanges in 2 cases (Fig.
2).
They were completely consistent with the intraoperative observation results.
In 10 cases the proper palmar digital arteries were displayed by CE-3D-WATSc and in 2 cases were not shown,
of which 9 were normal development and 1 was small (Fig.
3).
During operation the proper palmar...
Conclusion
CE-3D-WATSc has some application value in evaluating vessels of hand for CSM in children before operation.
