Imaging CT Central Pool Changes And Traumatic Brain Injury Prognosis

Objective: To study on the prognosis of the CT change of cisterna ambiens andtraumatic brain injury, patients injured admission check in time to the brain CT is thediagnostic method of choice and established therapy, rehabilitation assessment ofmorphological changes of brain CT ring pool for admission diagnosis, the patients withcraniocerebral injury of guideline for treatment and after discharge is clinical themeaning is very important, is beneficial to the recovery of guiding the treatment ofaccurate and objective judgment of prognosis.Methods:108cases of patients withtraumatic brain injury admitted in the emergency department of the first head CT scan(after30minutes to12hours after injury,), ring pool wrapped around the midbrain onboth sides, as the ring pool, easily found in the posteroanterior, so in the measurementloop pool midbrain level accurate width, precision for0.1mm.According to the changesof ambient cistern degree classification of six groups: type I: the central pool of occlusion;type II:0-0.5mm; type III:0.5-1mm;1-2mm; type IV: V:2-3mm; type VI:>3mm, andat the same time were observed in the midbrain form has no change.According to theGlasgow outcome score (GOS) standards are:1a better prognosis group (recovery isbetter, the residual);2poor prognosis group (severe disability, plant survival, death).Alldata were processed by statistical software SAS.Results: there were significantcorrelation ring pool morphological changes and GCS score, the central pool shapechange is more obvious, the lower the GCS, the prognosis is worse.The prognosis ofmorphological changes of type Ⅰ ring pool poor rate the most significant (comparedwith type VI, P <0.01), and when the ring pool deformation is1-3mm despite the badprognosis rate than type VI to be high, but the difference was not statistically significant (P>0.5).Midbrain compression for the prognosis of patients with craniocerebral injuryat the same time also has certain influence.The data confirm the prognosis of differentdegree of compression ring pool can affect patients with acute craniocerebral injuryrecovery and quality of life, and further proves that when the ring pool width>2mmgood prognosis, ring pool pressure <1mm, even when the ring pool complete occlusionand ring pool <0.5mm will increase significantly the prognosis of the patients the rate ofdisability and even death.Conclusion:So change ring pool image morphology providesimportant basis for evaluation the prognosis of patients with craniocerebral injury.
