Trachea And Thoracic Lines In Young Patients With Spontaneous Pneumothorax CT Measurement And Analysis Of Related Factors

Objective: For various reasons, the pleural cavity is communicated withatmosphere, air into the chest of the formation of the thorax pneumatosis, calledpneumothorax."Self" in patients with pneumothorax is called spontaneouspneumothorax, more common in young men, severe cases can be life-threatening.Spontaneous pneumothorax incidence rate is rising in recent years, especially since thelife expectancy increases, the incidence of spontaneous pneumothorax secondary tochronic obstructive pulmonary disease in the rate of increase. The great majority ofcases in the first first months after the onset of disease recurrence. If no effectivemeasures to prevent spontaneous pneumothorax in5years, the recurrence rate was43%.If no effective measures to prevent spontaneous pneumothorax in5years, therecurrence rate was43%. This research through the tracking measurement in136casesof16-30years old of young patients with spontaneous pneumothorax thorax and pipeline, and151cases of non diseased youth for comparison, preliminary study ofpathogenesis of spontaneous pneumothorax in young, and provide the scientific basisfor clinical diagnosis and treatment.Methods: From2008August to2012December, select young patients withspontaneous pneumothorax (Study Group) and136patients (mean age21.2years), nonspontaneous pneumothorax youth (control group)151patients (mean age21.5years).USE The Siemens SOMATOM Definition AS plus64rows of128layer MSCTscans chest，and measuring the anteroposterior diameter, chest diameter, width andlength of the windpipe trachea transverse thoracic on CT image. Calculate the horizontallength of the chest and thoracic anteroposterior diameter ratio, tracheal length todiameter ratio. Study group and control group, comparative study of the clinical treatment before and after treatment. The data were analyzed by SPSS19.0, the meancompared with t test, study groups before and after the treatment of thoracic and tracheaof the numerical comparison with rank sum test, the test level of α=0.0500Results:1. The study group included114male,22female, in which smokers orhad a smoking history of65, there were1people, has a history of pulmonary diseaseand16people, with chest CT confirmed pulmonary bulla in66people; The controlgroup consisted of young male126people, female25people, including smokers or hada smoking history of66, have a family history of0, had a history of pulmonary diseaseand7people, with chest CT confirmed pulmonary bulla in0people.2. The research group of thoracic transverse diameter was245.11±2.75mm,6.85±5.69mm chest diameter, pipe length of142.82±4.83mm, tracheal diameter of18.16±0.97mm; the control group transverse thoracic anteroposterior diameter was244.42±3.38mm,91.28±4.6mm chest diameter, pipe length of142.05±3.99mm, pipediameter of19.15±0.74mm; transverse thoracic study group size and thoracicanteroposterior diameter ratio and the tracheal length to diameter ratios were2.82±0.07,7.864±0.18, the corresponding numerical control group was2.677±0.11,7.417±0.21. Transverse thoracic study group size, pipe length, horizontal length of the chestand thoracic anteroposterior diameter ratio and tracheal length to diameter ratio isobviously higher than that of control group, the difference was statistically significant(P<0.05).3. Patients with spontaneous pneumothorax after clinical treatment of chestanteroposterior, transverse thoracic diameter, length and transverse diameter of tracheatrachea average values were244.47mm,80.57mm,141.70mm and17.70mm, comparedwith before treatment significantly reduced, the difference was significant (P<0.05).Conclusion：1.There are differences in the thorax and thoracic tracheal warp ofspontaneous pneumothorax patients and healthy people, description of thoracicdysplasia (flat thorax) and slender pipe and the pathogenesis of primary spontaneouspneumothorax.2. The chest of patients with spontaneous pneumothorax after clinical treatment isrelatively narrow, tracheal coarsening.3. There is a significant correlation between the youth of spontaneouspneumothorax and suffering from pulmonary bulla.4. In daily medical popular science education and the medical work, the lanky,chest flat type teenagers should be special to strengthen health education, told their attention to self protection in daily life, to avoid a sudden increase in airway pressurewithout ready in case the actions and behavior, reduce the chance of pneumothorax.
