A focal nodular hyperplasia (FNH) rarely requires surgical intervention unless complications or clinical symptoms come into play. In 2 female patients, ages 35 and 44, with symptomatic tumors of that entity (10 and 14 cm, respectively, in size) we performed a laparoscopic liver resection. Directly before undergoing this operation they underwent a selective angiographic embolization of the arterial inflow for control of hemorrhage by application of polyvinyl alcohol particles to the afferent arteries. This procedure led to a complete interruption in arterial inflow and the subsequent laparoscopic resection itself could be carried out as planned with minimal blood loss as well an uncomplicated postoperative course. The patients demonstrated a high degree of subjective satisfaction with the procedure. A reduction in arterial inflow through selective embolization is a useful tool in the preparation for laparoscopic resection of large, well-vascularized liver tumors.
