Feasibility of ultrasound-guided intranodal lymphangiogram for thoracic duct embolization.

摘要: Abstract Purpose To show the feasibility of opacifying thoracic duct using ultrasound-guided intranodal lymphangiogram (IL) for embolization (TDE). Materials and Methods Six patients (two women four men, mean age, 59.2 y [range, 43–74 y]) underwent IL TDE chylothorax. Under ultrasound guidance, a needle was positioned in groin lymph node, lipiodol injected. The catheterized, performed as indicated. Cumulative times from start procedure until initiation lymphangiogram, identification target lymphatic, catheterization duct, completion were collected. Times compared with control group six 66.7 49–82 who had undergone pedal lymphangiography (PL). Results opacification, catheterization, successful all cases. (mean ± standard deviation) PL groups ( i ) initial 20.5 minutes 8.6 46.5 22.6, ii lymphatic 60.5 18.2 110.5 31.6, iii 79.0 28.9 128.2 37.0, iv 125.8 49.0 152.8 36.4. Conclusions is feasible technique to visualize embolization. Using IL, may be more quickly visualized catheterized than PL.
