Introduction:
The anterior approach to the inferior vena cava (IVC) by the liver hanging maneuver is effective in resecting large retrohepatic tumors without mobilizing the right lobe.
Case presentation:
A 50-year-old man was referred to our hospital with a diagnosis of pheochromocytoma. He had severe congestive heart failure and cardiac ejection fraction was 15%. Abdominal magnetic resonance imaging (MRI) and ultrasonography (US) showed an adrenal mass about 80 mm in diameter. The tumor-infiltrated posterior segment of the right hepatic lobe and tumor were widely attached to the IVC. After treatment of congestive heart failure with conservative therapy, surgery was planned. Right adrenectomy and right hepatectomy were performed, the latter using the liver hanging maneuver to avoid mobilizing the right lobe, and we were able to minimize blood pressure fluctuations and perform the operation safely. The histopathologic diagnosis was malignant pheochromocytoma.
Conclusions:
We performed right hepatectomy without mobilizing the right lobe by the liver hanging maneuver and minimized stimulation of the tumor. We could perform the operation safely using the liver hanging maneuver, which seems effective in such cases.
