title: CT angiography-guided single-stage release of adjacent webspaces in non-Apert syndactyly.
abstract: We describe the CT angiography protocol and surgical technique utilized at our institution for single-stage release of adjacent web-spaces in non-Apert syndactyly. In a series of seven consecutive hands we analyse syndactyly anatomy, CT angiographic findings, operative details, and complications. Outcomes were assessed with a functional activity evaluation, range of motion, and a parental visual analogue scale. Seven affected hands in four patients underwent single-stage release of adjacent webspaces. In all cases, the CT angiogram correctly predicted the presence of at least one artery supplying each digit. There were no cases of digital ischemia or loss. Angiographically guided, single-stage release of adjacent webspaces is technically feasible and benefits patients by reducing the number of surgical stages and allowing complete release to be achieved at an earlier age compared with the standard multi-stage approach.
