Kyphoscoliosis ventilatory insufficiency: noninvasive management outcomes.
American journal of physical medicine & rehabilitation, 2000Co-Authors: Gloria Ferris, Emilio Servera-pieras, Pedro Vergara, Alice C. Tzeng, Máximo Pérez, Julio Marín, John R. BachAbstract:To determine the effects on symptoms, pulmonary function, sleep, and other clinical variables of treating Kyphoscoliosis-associated chronic alveolar hypoventilation with nocturnal nasal ventilation. Sixteen patients with Kyphoscoliosis were treated with nocturnal nasal ventilation delivered by volume-cycled (seven patients) and pressure-cycled (nine patients) ventilators. Dyspnea, morning headaches, fatigue, hypersomnolence, and perceived sleep quality were assessed. All pretreatment symptoms improved significantly with nasal ventilation. Likewise, PaO2 (mm Hg), PaO2/FlO2, PaCO2 (mm Hg), pH, and forced vital capacity (in milliliters and as a percentage of predicted normal) significantly improved with treatment. Maximum inspiratory pressures and maximum expiratory pressures also significantly increased. Tidal volumes increased significantly and breathing frequency decreased (not significant). Although perceived sleep quality improved, as well as sleep oxyhemoglobin saturation, there was no significant change in sleep architecture. Hospitalization days for respiratory difficulties also decreased from 10.9 +/- 13.3 days in the 6 mo before intermittent positive-pressure ventilation to 0 days during the first 6 mo of treatment. Although not apparently affecting sleep architecture, nocturnal nasal ventilation can significantly improve nocturnal and daytime blood gases, pulmonary function, and symptoms of hypoventilation for patients with severe Kyphoscoliosis.

Progressive Kyphoscoliosis associated with tethered cord treated by posterior vertebral column resection: a case report.
Spine, 2009Co-Authors: Morio Matsumoto, Kota Watanabe, Takashi Tsuji, Ken J. Ishii, Hironari Takaishi, Masaya Nakamura, Yoshiaki Toyama, Kazuhiro ChibaAbstract:STUDY DESIGN.: A case report. OBJECTIVES.: To report a case of progressive Kyphoscoliosis associated with a tethered cord that was corrected by posterior vertebral column resection after complicated untethering surgery. SUMMARY OF BACKGROUND DATA.: There have been few clinical reports on posterior vertebral column resection conducted for severe deformity associated with a tethered cord. METHODS.: A patient with progressive Kyphoscoliosis associated with a tethered cord first underwent untethering surgery, resulting in neurologic deterioration. Posterior vertebral column resection was performed to correct the Kyphoscoliosis while shortening the spinal column to prevent the spinal cord from stretch injury. RESULTS.: Good correction of Kyphoscoliosis was obtained without further neurologic deterioration. The Cobb angles of scoliosis was 103 degrees before surgery and 25 degrees after surgery (correction rate; 75.7%), and that of kyphosis was 90 degrees and 36 degrees , respectively (correction rate; 60.0%). CONCLUSION.: Correction of progressive Kyphoscoliosis associated with a tethered cord can be achieved successfully by posterior vertebral column resection even after complicated untethering surgery.

a successful pregnancy in a woman with severe idiopathic Kyphoscoliosis a case report
European Respiratory Journal, 2016Co-Authors: Ilona Rousalova, Alena Vlachova, Petr Korbelar, Lenka Patlejchova, Michal AndelAbstract:Introduction: Kyphoscoliosis is defined as an abnormal curvature of the spine in both coronal and sagittal plane. The prevalence in the general population varies significantly from 0.3% to 15.3%. Restrictive pulmonary dysfunction is the most common reported pulmonary impairment in these patients. The women with extremely severe spinal deformities are commonly considered to have high-risk pregnancies due to impaired adaptation of the thoracoabdominal architecture during pregnancy. We report a case of a successful pregnancy in a woman with severe uncorrected Kyphoscoliosis and total lung capacity (TLC) of 1.46 L. Case Report/Methods: A 27-year-old primigravid woman presented at 34 week of pregnancy in the pulmonology ambulance with breathlessness and dry cough. She was diagnosed with idiopathic Kyphoscoliosis and agenesis of left kidney after delivery. The Cobb9s angle was 90°C and lung function as follow: TLC 1.46 L (45% of predicted), FVC 0.83 L (35% of predicted), FEV1 0.56 L (27% of predicted), FEV1/FVC 67 (79% of predicted), D L CO 0.53 (10% of predicted). Results: Caesarean section under general anesthesia was performed through a Geppert incision due to preeclampsia. A live healthy female infant was born. Conclusions: This case report demonstrates, that despite severe Kyphoscoliosis the patient was able to carry a pregnancy to 34 weeks of gestation without non-invasive ventilation. Multidisciplinary care with close monitoring is necessary in pregnant women with severe impairment of lung function.

Successful Pregnancy in a Patient with Spinal Muscular Atrophy and Severe Kyphoscoliosis
American journal of physical medicine & rehabilitation, 2003Co-Authors: Roger Yim, Kristi L. Kirschner, Eileen Murphy, John Parson, Christopher WinslowAbstract:Pregnancy imposes a load on the respiratory system that is usually easily assumed because of alterations in the thoracoabdominal architecture. It is presumed that the respiratory mechanical disadvantage of severe Kyphoscoliosis and the muscle weakness of spinal muscular atrophy impede these adaptations sufficiently to preclude a successful gestation. We report the case of a successful pregnancy in a woman with spinal muscular atrophy, severe uncorrected scoliosis, and the lowest spirometric values reported in the literature without the use of ventilatory support. This patient demonstrates that women with severe Kyphoscoliosis and a profound ventilatory limitation can carry a successful pregnancy well into the third trimester without requiring full ventilatory support.
