PURPOSE: To demonstrate the utility of computed tomography angiographic planning 
of a single-stage, complete release of syndactyly in Apert syndrome.
METHODS: Computed tomography angiograms were performed as a preoperative 
planning tool in 6 patients. Five came to surgery. All had a single-stage 
operation for complete release of their syndactyly.
RESULTS: Five patients, ranging from Upton type 1 to type 3 Apert hand 
deformities, have had preoperative computed tomography angiography that 
delineated the vascular anatomy. This allowed planning and execution of a 
single-stage syndactyly release in all patients. The preoperative imaging 
identified noteworthy abnormalities in vascular anatomy that were incorporated 
into surgical planning.
CONCLUSIONS: The protocol presented allows preoperative planning and 
single-stage operation for complete release of syndactyly in patients with Apert 
syndrome.
