Resection of extensive segments of inferior vena cava without reconstruction in the treatment of renal carcinoma with inferior vena cava tumor thrombus: A case report.

We present a 55-year-old male patient with right renal carcinoma with long inferior vena cava (IVC) tumor thrombus who underwent robot-assisted laparoscopic radical nephrectomy with extensive IVC resection and left renal vein ligation. The patient had a history of hematuria only prior to admission. Our case involved resection of the entire abdominal segment of the IVC and left renal vein without reconstruction. Unfortunately, the patient passed away over a year after the surgery due to brain metastasis.
