Single-session alcohol sclerotherapy in symptomatic benign hepatic cysts -Long-term results

Purpose: To evaluate the long-term results of single-session alcohol sclero therapy of symptomatic benign liver cysts. Material and Methods: 23 cysts in 19 patients were treated by single-sessio n percutaneous catheterization and injection of 96% ethanol. Evaluation of longterm results was possible in 11 cysts (volume 200-2,700 ml, mean 1,317 ml) in 11 patients. Time of observation was 12-67 months, mean 38.3 months. Results. The reduction of volume was 93-100% (mean 98%). The re-accumulatio n of fluid after therapy seen in 9 patients proved to be transitory. Except for pain there were no complications. Conclusion: Single-session sclerotherapy resulted in satisfactory cyst volu me reduction in all 11 long-term follow-up patients.
