Abstract

Objective: To investigate MSCT morphologic characteristics of the diaphragmatic crevasse in traumatic diaphragmatic hernia(TDH). Materials and Methods: The MSCT features of 27 patients with TDH were analyzed retrospectively, which included 21 cases of blunt diaphragmatic hernia(BDH)(all confirmed by surgery) and 6 cases of iatrogenic diaphragmatic hernia(IDH)(2 surgically confirmed). Twenty-seven patients all underwent MSCT scanning, slantwise, projective and linear methods of MPR reconstruction were adopted to observe and compare diaphragmatic crevasse for its display and morphological characteristics. Result: Diaphragm crevasse can display in 21 cases of the 27 cases with slantwise methods of MPR(77.8%), besides 24 cases(88.9%) with projective methods and 20 cases(74.1%) with linear methods, average 77.2%, without difference in coronal or sagittal sites of the last two methods. Of the 27 cases with TDH, the shape of the crevasse was not clearly displayed, 11 ones could not show right side(36.7%, 11/30), 15 ones could not display left side(14.3%, 15/105), t=6.51, P<0.05. Form of diaphragmatic crevasse is mainly classic round, oval or spindle, of which, 16 cases(59.3%), 20 cases(45.5%), 26 cases(59.1%) displayed classic round by tilted method, projective method and linear method in turn, likewise 11 cases(40.7%), 24 cases(54.5%), 18 cases(40.9%) were displayed oval or spindle by three methods above mentioned in turn. Conclusion: The morphological characteristics of break in the most of TDH can be displayed directly or indirectly, the demonstrative situation of tilted method and linear method is similar; and more objective than that of the projective ones.
