Life-threatening hemorrhage after liver radiofrequency ablation successfully controlled by transarterial embolization

Figure 1 The exposure and radiofrequency ablation of the lesion in the caudate lobe under laparotomy. A: The tumor found in the caudate lobe. The arrow indicates the lesion; B: The largest tumor in the Caudate lobe measuring 4 cm was treated with radiofrequency (RF) ablation, with RF electrodes were placed at the tumor site.

Figure 2 Introperative ultrosound study showed a hepatic artery pseudoaneurysm within the hematoma.

Figure 3 Hepatic angiography before and after coil embolization. A: Hepatic angiography revealed a pseudoaneurysm in the lower left hepatic artery; B; Hepatic angiography immediately after coil embolization. Coils were placed using a 2.1 F microcatheter into and proximal to the pseudoaneurysm. The pseudoaneurysm was then excluded.

Figure 4 Computed tomography scan acquired 1 mo later. The image revealed that the pseudoaneurysm had disappeared. No tumor enhancement was apparent at the ablated site. The coils used for embolization were visualized.
