  • Effects of Pectus excavatum on the Spine of Pectus excavatum Patients with Scoliosis
    Journal of Healthcare Engineering, 2017
    Co-Authors: Wei-hong Zhong, Jinduo Ye, Jing-jing Feng, Liyang Geng, Guang-pu Lu, Chunqiu Zhang
    Abstract:

    Background. There is high risk in the correction surgery of Pectus excavatum with scoliosis because of the lack of the correction mechanism of Pectus excavatum with scoliosis. This study performed a comprehensive analysis about the impact that Pectus excavatum had on scoliosis and elaborated its biomechanical mechanism in Pectus excavatum patients with scoliosis. Methods. 37 Pectus excavatum patients were selected. According to age, Haller index of Pectus excavatum, offset coefficient, vertical position, sternal torsion angle, and asymmetric index, 37 patients were, respectively, divided into 2 compared groups. The result was statistically calculated. Results. The scoliosis incidence and severity did not correlate with Haller index, offset coefficient, vertical position, sternal torsion angle, and asymmetric index of Pectus excavatum, and there was no statistical significance between the two compared groups. Conclusions. The incidence and severity of scoliosis in PE patients with scoliosis have nothing to do with the geometric parameters of Pectus excavatum but correlate with age. The scoliosis will aggravate with the increase of age. The heart may provide an asymmetric horizontal force to push the spines to the right. The mechanism of how the biomechanical factors exert influences on spines needs to be further investigated to keep the spine stable.

  • Numerical simulation of minimally invasive correction surgery of Pectus excavatum with scoliosis
    2014 IEEE International Conference on Mechatronics and Automation, 2014
    Co-Authors: Meijiao Zhao, Wei-hong Zhong, Jinduo Ye, Peibei Dong, Chunqiu Zhang
    Abstract:

    Objective: Establish three dimensional solid model of thorax of Pectus excavatum with scoliosis, carry out numerical simulation of minimally invasive correction surgery of Pectus excavatum with scoliosis, study the influence how Pectus excavatum correction affect scoliosis, and conduct clinical correction surgery. Methods: Reconstructed the model of thorax of Pectus excavatum with scoliosis by CT images with software Mimics, simulate minimally invasive correction process by considering geometrical non-linear finit element method, design correction surgery plan, and carry out correction surgery according to the result of numerical calculation. Result: The result of calculation indicates that if the spine twisted toward the direction of the location of Pectus excavatum, the scoliosis will be improved, the symptom of which will be ease. The surgery plan designed by the result of numerical calculation has been adapted to clinical surgery, and a good result has been obtained.

  • a modified nuss procedure for late adolescent and adult Pectus excavatum
    World Journal of Surgery, 2010
    Co-Authors: Yoo Sang Yoon, Yong Soo Choi, Young Mog Shim
    Abstract:

    Background Although the Nuss procedure has been widely adopted as a standard procedure in children with Pectus excavatum, reports focusing on its use in adults are rare. We retrospectively reviewed postoperative results to evaluate the safety and efficacy of the Nuss procedure in late adolescents and adults with Pectus excavatum.

  • surgical repair of Pectus excavatum and carinatum
    Seminars in Thoracic and Cardiovascular Surgery, 2009
    Co-Authors: Francis Robicsek, Larry T Watts, Alexander A Fokin
    Abstract:

    The author discusses different forms of Pectus deformities and presents appropriate surgical methods he developed for their correction. For Pectus excavatum, the surgical technique includes conservative sub-perichondral resection of deformed costal cartilages and detachment of the xiphoid process. A transverse sternotomy is performed at the upper level of the deformed sternum, which is then bent forward. The corrected sternal position is secured by a "hammock" of synthetic mesh, spread behind the sternum, and attached to the respective cartilage remnants. The pectoralis muscles are then united presternally. The initial steps of Pectus carinatum correction are similar to that of Pectus excavatum. The sternum, however, is not freed of its environment. A length of 3-4 cm is resected from the distal sternum and the xiphoid process is reattached in the proper anatomical direction. Measures to correct different anatomical varieties, such as pouter pigeon breast, asymmetrical Pectus excavatum, and carinatum, are discussed individually.
