Surgical management of malignant pheochromocytoma with tumor-induced venous obstruction involving the entrance to the right atrium is challenging. The risk of marked hypotension and hemodynamic instability following clamping of the vena cava is increased as a consequence of the sudden decrease in circulating catecholamines. The use of cardiac bypass, however is burdened with additional operating time and coagulopathy. The present report illustrates that veno-venous bypass is a valuable tool during resection of phenochromocytoma with a large vena caval tumor thrombus.
[Show abstract][Hide abstract] ABSTRACT: We report the first case of successful surgical resection of a malignant phaeochromocytoma with tumour extension into vena cava and right atrium in a patient with multiple endocrine neoplasia type 2A. A 21-year-old woman with genetic confirmation of multiple endocrine neoplasia type 2A syndrome was diagnosed with a very rare case of malignant phaeochromocytoma with tumour thrombus extension into vena cava and right atrium causing Budd-Chiari syndrome. It posed a challenge to the surgeons with regard to complete tumour resection and vascular control. Reviewing the limited literature, surgical resection by means of cardiopulmonary bypass with hypothermic circulatory arrest has been reported with success in phaeochromocytoma with advance vascular involvement. Adopting this approach, adrenalectomy with complete thrombus excision by inferior vena cava exploration and right atriotomy were performed successfully by a multidisciplinary team.

[Show abstract][Hide abstract] ABSTRACT: Adrenal gland metastasis from osteogenic sarcoma is extremely rare and is an atypical location for metastasis. Vascular hepatic exclusion techniques and the use of venovenous bypass with cardiac surgical techniques may be required to resect large adrenal masses that have invaded the inferior vena cava to achieve curative resection. The use of newer chemotherapeutic agents and aggressive surgical resection have prolonged the survival of patients with osteosarcoma.
[Show abstract][Hide abstract] ABSTRACT: A 61-year-old man presented with feeling of bloating, remarkable sweating, and body weight loss. We diagnosed right pheochromocytoma with inferior vena cava (IVC) thrombus by some plasma and urine catecholamine and their metabolites data and imaging findings. The patient underwent right adrenalectomy and IVC thrombectomy without use of cardiopulmonary bypass. Pathological finding showed potentially malignant pheochromocytoma. After operation, his subjective symptom disappeared, and abnormal plasma and urine catecholamine and their metabolites data fell to normal range. It is very important to get preoperative information of the exact location of tumor thrombus for the safe surgical management of pheochromocytoma with IVC thrombus. Magnetic resonance imaging (MRI) and ultrasound imaging more useful for diagnosis of the exact location of IVC thrombus.
