{Abstract}: <B>BACKGROUND: </B>Pheochromocytoma surgery is generally challenging for surgeons and anesthesiologists for cardiovascular complications.<BR><B>METHODS: </B>A 54-year-old Japanese man was found to have a large right pheochromocytoma infiltrating the posterior part of his liver and vena cava and multiple lung metastases. After retroperitoneal laparoscopic dissection of the dorsal side of the tumor and ligation of the feeding vessels, total resection of the primary tumor, extended posterior sectional hepatectomy, and partial vena cava resection were performed by open surgery via a thoracoabdominal approach. Abundant congestive bleeding with instability of vital signs occurred during transection. It could be finally controlled by dissect the remnant feeding artery in the inmost space. Prior control of arterial in-flow enabled successful completion of the planned surgical procedure. The patient has now survived for 27 months since resection of the primary lesion.<BR><B>CONCLUSIONS: </B>Ligation of the feeding arteries to this hypervascular catecholamine-releasing tumor via a retroperitoneal laparoscopic approach prior to performing combined organ resection facilitated successful excision of this large malignant pheochromocytoma.
