Thorax Ct

Pectus excavatum is the most common congenital chest wall deformity. Extensive corrective surgery prior to age 3 may disturb chest wall growth and result in a constricted thorax. We paid particular attention to the role of thoracic spiral computed tomography (CT) image and 3D 1modeling of patient with pectus excavatum. Thoracic spiral CT was always performed on patient who had developed restrictive chest walls following pectus excavatum surgery. These patients then underwent a Nuss operation to elevate the sternum and attempt to correct their restrictive chest wall defects. The method used the CT image to set up 3D modeling reconstruction defined the orientation of the ribs and costal cartilages and their relationship to the sternum, allowing exact preoperative measurement of the bony rib cage and guiding individualized operative correction. It also has laid foundation for simulation of Nuss operative correction of pectus excavatum and has important reference value in selecting and positioning of support frame. As was shown in the result, the accuracy of costal cartilage’s model was promoted in certain extent. Manual work of model modification was significantly reduced and the period of 3D modeling was shortened by approximately 40%. The 3D modeling of spiral CT data is useful in both preoperative and postoperative evaluation.

AbstractSurgical procedures for pectus excavatum (PE) repair, such as minimally invasive repair of pectus excavatum or similar interventions (modified open videoendoscopically assisted repair of pectus excavatum), for remodeling the anterior thoracic wall may finally not always achieve sufficiently pleasing aesthetic results. Particularly in the asymmetric and polymorphic cases, remnant deformities may still be present after any sophisticated remodeling attempt. On the other hand, some cases despite optimal surgical management develop mild recurrences with partial concavity or rib cartilage distortion shortly after pectus-bar removal. Secondary treatment options then may include open access surgery, resection, or reshaping of deformed and prominent costal cartilage. Residual concave areas can be filled by autologous tissue, such as cartilage chips, liposhifting, or implantation of customized alloplastics. To provide the best options for a variety of primary or secondary postsurgical expressions of anterior wall deformities, any physician dealing with PE corrections should be familiar with various shaping and complementary reconstructive techniques or at least should have knowledge of such. However, among treating surgeons, there is an awareness that no single method can be applied for every kind of funnel chest deformity. Careful selection of appropriate techniques, either as a single approach for the ordinary deformities or in conjunction with ancillary procedures for the intricate cases, should be mandatory, based on the heterogeneity of symptoms, severity, expectations, and surgical and technical resources. A variety of such ancillary reconstructive procedures for PE repair are explained and illustrated herewith.
