Hemorrhage is the main complication of hepatocellular adenoma (HCA). The aim of this study was to describe a single center's evolving management of patients with hemorrhagic HCA. Between 1990 and 2013, all patients with hemorrhagic HCA were included. During the study period, the management evolved from urgent surgery (period <2004) to arterial embolization with (period, 2004–2010) or without (period > 2010) delayed resection. A total of 56 patients were identified. The median (range) size of HCA and the hematoma was 80 mm (35–160) and 50 mm (10–160). Patients were treated by urgent resection (group 1, n = 6), delayed resection with or without embolization (group 2, n = 43) and systematic embolization without surgery (group 3, n = 7). Embolization was performed in 0/6, 15/43 and 7/7 in groups 1, 2 and 3. Urgent resection was associated with higher morbidity (p < 0.001). Complete necrosis was observed in 0/6, 13/43 and 3/7 patients, and on histology it was associated with embolization (p = 0.001), a hematoma-tumor ratio > 60% (p = 0.046) and a cystic non-viable lesion before surgery (p < 0.001). Hemodynamic stability can be achieved in patients presenting with hemorrhagic HCA by none surgical means. Subsequent surgery can be completely avoided with such an approach in up to 40% of patients.
