Study Cohort
This retrospective, institutional review board–approved, Health Insurance Portability and Accountability Act–compliant study was conducted with a study cohort of 57 patients (26 women, 31 men; mean age, 63 y, age range, 11–84 y) (Table 1). Informed consent was waived per institutional review board protocol. Ten patients underwent lymphatic intervention apart from INL only, INL with TDE, or INL with TDD. One patient was immediately lost to follow-up. Seven patients did not meet algorithmic
Results
Mean daily effusion output was 1,063 mL (range, 200–3,000 mL). Mean Lipiodol injected was 8.5 mL (range, 4–15 mL). There was no difference in sex distribution of patients undergoing INL with TDE, INL with TDD, or INL only (INL with TDE, 66.7% male; INL with TDD, 50% male; INL only, 50% male; P = .51), although the mean age of patients in the INL only group was younger compared with the other groups (INL with TDE, mean 66.5 y [range, 47–83 y]; INL with TDD, mean 67.1 y [range, 50–81 y]; INL
Discussion
INL has hitherto been an understudied intervention for management of chylous effusions. Previous studies evaluating the clinical success rate with BPL with TDE or TDD have reported rates of 45%–74% (10, 12, 13, 14). A recently published study mostly using INL to access the lymphatic system for abdominal intervention documented a clinical success rate of 94% (21). The present study documented an overall clinical success rate of all image-guided percutaneous interventions of 71%. Clinical and
