Abstract

lymphangiography, identification of the liver lymphatic abnormalities, volume of injected contrast, fluoroscopy time, and complications were recorded. Results: The indications for liver lymphangiography included refractory chylous effusion (6 patients), refractory ascites in patients with heart failure and liver cirrhosis (6), protein losing enteropathy (4), refractory chylothorax (1), and refractory plastic bronchitis (1). Technical success rate was 16/18 (89%). Lymphangiography identified abnormal findings in 16/25 (64%) procedures. All patient's liver lymphangiograms demonstrated an abnormal connection to either the duodenum or mesentery. Mean fluoroscopy time was 49.9 minutes (8-98.6 minutes). Mean lipiodol volume was 6.4 mL (1.5-15 mL). In 17 patients, postprocedural liver function testing (LFTs) was available. Four procedures resulted in a Grade 1 transaminitis, 4 procedures resulted in a Grade 2 transaminitis, and 4 procedures resulted in a Grade 3 transaminitis. All patients remained clinically asymptomatic, and LFTs returned to baseline values within several weeks of the procedure (SIR complication classification 1a). Conclusions: Liver lymphangiography with embolization is a technically feasible and safe procedure that provides important diagnostic information and guidance for interventional therapy.
