Intravascular ultrasound (IU) imaging provides detailed tomographic images of the vascular wall and lumen. 1–3 One liability of this novel imaging modality, however, is the inability to view a given vascular segment in a composite format; detailed cross-sectional images are thus provided at the expense of a longitudinal perspective. The circumferential nature of a postangioplasty dissection may be well demonstrated by IU, for example, but the full longitudinal extent may not be readily apparent, even after repeated review of the videotaped images recorded over the length of the involved segment. Computer-based 3-dimensional (3-D) reconstruction (R) from serially recorded IU images offers a potential solution to this problem. By creating a longitudinal display of the entire vascular segment, 3-DR offers a composite format for presentation of detailed IU data, facilitating comparison of selected cross-sectional ullages with those that are proximal and distal. Previous studies from our laboratory have outlined the concepts, technique and instrumentation used for 3-DR, and demonstrated the feasibility and potential use of 3-DR. 4–6 Whereas off-line analysis of such 3-DRs has provided insight into mechanisms of recanalization, to be clinically useful during interventional procedures, 3-D image generation must be rapid, if not instantaneous. We report here the use of real-time 3-DR from IU images recorded during percutaneous iliac artery revascularization in 2 patients.
