Abstract
To report and discuss four cases of renal cell carcinoma (RCC) in which preoperative investigations yielded contradictory results regarding the cranial extension of propagation of the tumor thrombus into the vena cava. An intraoperative ultrasound scan (IOU) was performed in all cases to identify the exact level of the tumor thrombus. We have performed an IOU of the vena cava in four patients with RCC propagation into the inferior vena cava. Preoperative investigations were performed in all patients and consisted of abdominal Ultrasound scan (USS), contrast enhanced CT scan and gadolinium enhanced MRI scan. Intraoperative ultrasound has identified correctly the cranial extension and the absence of tumor thrombus infiltration in all patients. The thrombus reached the suprahepatic vena cava in two cases and was confined to the infrahepatic vena cava in the remainder.
