ABSTRACT
Objective To investigate the diagnostic values of direct lymphangiography for the thoracic duct outlet obstruction.Methods The image data of direct lymphangiography were retrospectively analyzed in 124 patients with lymphedema,Chylothorax,chylous ascites,chyluria and intestinal lymphangiectasis,and compared with the results of neck thoracic duct surgical exploration,2 radiologists reviewed DLG DSA images in a double blind manner.The number of neck stem,subclavian stem,bronchialmediastinal stem and TD terminal into blood obstruction on the operation side showed by DLG were assessed using Kappa analysis.Results Of 124 patients,80 patients had the left cervical lymphatic stem reflux on DLG,75 patients with the left subclavian lymphatic stem reflux,30 patients with the left bronchial-mediastinal lymphatie stem reflux,118 patients showed the thoracic duct outlet barrier into the blood.The consistency rate of DLG were 89.9% (80/89),92.6% (75/81),90.9% (30/33) and 95.2% (118/124) compared with the neck thoracic duct surgical exploration.Tow radiologists had a high degree of diagnostic consistency (K =0.82,P < 0.05).In addition,114 patients (91.9%) had tortuous,dilated waist lymphatic stem,only 10 patients (8.1%) were normal.The cisterna chyli reflux were found in 92 patients (74.2%),intestinal stem reflux in 16 patients (12.9%),reflux to the kidney area in 11 patients (8.9%),to the pericardium reflux in 5 patients (4.0%),vaginal lymphatic leakage in 7 patients (5.6%),retroperitoneal lymph leakage in 2 patients (1.6%),pleural lymphatic leakage in 3 patients (2.4%),tracheal lymph leakage in 1 patient (0.8%).Conclusion Direct lymphangiography has a high consistency with the cervical thoracic duct surgical exploration in displaying thoracic duct outlet obstruction.
