CT Angiography for Surgical Planning in Face Transplantation Candidates

Abstract

SUMMARY:Facial allotransplantation replaces missing facial structures with anatomically identical tissues, providing desired functional, esthetic, and psychosocial benefits far superior to those of conventional methods. On the basis of very encouraging initial results, it is likely that more procedures will be performed in the near future. Typical candidates have extremely complex vascular anatomy due to severe injury and/or multiple prior reconstructive attempts; thus, each procedure is uniquely determined by the defects and vascular anatomy of the candidate. We detail CT angiography vascular mapping, noting the clinical relevance of the imaging, the angiosome concept and noninvasive delineation of the key vessels, and current controversies related to the vascular anastomoses.

Influence of using a single facial vein as outflow in full-face transplantation: A three-dimensional computed tomographic study

“…This gives a perioperative take-back rate of face transplantation of seven, 4% (two out of 27 transplants) of which is slightly lower in comparison with conventional head and neck free tissuetransfer reconstruction, which ranges around 10%. 6e8 This low perioperative take-back rate in face transplantation maybe due to careful planning including vascular mapping of the donor and recipient, 13 performance of multiple anastomoses in both sides of the face, and that face transplantations are performed by a highly experienced microsurgeons.…”

Evaluation of velopharyngeal closure by 4D imaging using 320-detector-row computed tomography

“…Modern CT imaging enables fourdimensional (4D) scanning, wherein dynamic blood flow or movement of an organ can be characterized. 10,11 The purpose of this study was to validate the use of a novel 4D-CT technique for the morphological and kinematic evaluation Figure 1 Comparison between cephalometric evaluation and 4D airway CT in patient 4. Note the discrepancy between the cephalometry (c) and 4D airway CT (f) images during phonation [i:].…”

Transformation of Face Transplants: Volumetric and Morphologic Graft Changes Resemble Aging After Facial Allotransplantation

“…Imaging details have been reported (6)(7)(8). For this project, 1 Â 0.5-mm (overlapping) reconstructed images were transferred to a dedicated workstation (Vitrea version 6.1; Vital Images, Minnetonka, MN).…”
