Evaluation Of Endobronchial Ultrasound In The Diagnosis Of Bronchial Submucosal Vessels Malformation

Objective To explore the history, bronchoscope manifestations,Endobronchial ultrasonography manifestations of different bronchial mucosa protrusions lesions,in order to raise awareness of bronchial mucosa protrusions lesions, reduce the inadvertent biopsy for bronchial submucosal vessels malformation.Methods Collection bronchial mucosa protrusions, according to the result of EBUS we divide into groups : the submucosal vessels malformation group 、 mucosal thickening group、cyst group.Record selected cases information: gender, age,the bronchoscope signs( bronchial mucosa protrusions location, shape, colour and lustre, mucosal surface expansion),chest computed tomography, ultrasonic bronchoscope image and so on.To explore the history,bronchoscope manifestations,Endobronchial ultrasonography manifestations of different bronchial mucosa protrusions lesions.Results 43 bronchial mucosa protrusions, EBUS diagnosis of submucosal vessels malformation in 21(48.8%), mucosal thickening of 19(44.2%), submucosal cyst 3(6.7%).The same proportion of vessels: the proportion of the central airway,40.0%(4/10), upper lobe,66.7%(6/9), lower lobe,42.8%(3/7), upper left lobe,40.0%(4/10), the left lower lobe(4/7,57.1%).Shape:24 semicircle bronchial mucosa protrusions, submucosal vessels malformation in 11(45.8%), mucosal thickening of 12(50.0%), submucosal cyst 1(4.2%).17 flat protrusions, submucosal vessels malformation in 8(47.1%), mucosal thickening of 7(41.2%), submucosal cyst 2(11.8%);2 nodular protrusions, submucosal vessels malformation in 2(100%).Lustre: in five pale protrusions, submucosal veins 1(20%), mucosal thickening of 4(80%), 38 protrusions are consistent with the surrounding tissue, submucosal vessels malformation in 19(50%), mucosal thickening in 16(42%), submucosal cyst 3(21%).1 surface capillaries expansion, submucosal veins 1(100%), 42 surface withoutthe capillaries expansion, submucosal vessels malformation in 19(45%), mucosal thickening of 20(48%), submucosal cyst 3(7%).2 mucosal surface with pulsation are all submucosal veins(100%), 41 mucosal surface without pulsation, submucosal vessels malformation in 18(43.9%), mucosal thickening of 20(51.2%), submucosal cyst 3(7.3%);Conclusions 1, Eronchial mucosa protrusions are mainly caused by bronchial submucosal vessels malformation;2,EBUS examinations are important examinations for bronchial mucosa protrusions.
