      We wholeheartedly agree that these highly complex cases should only be performed at high-volume centers with specialized surgical expertise. While careful review of available imaging and thorough preoperative planning should be routine for any complex case, as noted the operating surgeon must rely on real-time assessment in the operating room to optimize safe and effective removal of the tumor and thrombus. Some preoperative data that may predict the need for cavectomy include:
      • 1.
        Anterior-posterior or coronal diameter of the IVC > 3.5cm
        • Psutka SP
        • Boorjian SA
        • Thompson RH
        • et al.
        Clinical and radiographic predictors of the need for inferior vena cava resection during nephrectomy for patients with renal cell carcinoma and caval tumour thrombus.
      • 2.
        Radiographic identification of complete occlusion of the IVC at the renal vein ostium
        • Psutka SP
        • Boorjian SA
        • Thompson RH
        • et al.
        Clinical and radiographic predictors of the need for inferior vena cava resection during nephrectomy for patients with renal cell carcinoma and caval tumour thrombus.
      • 3.
        Significant infrarenal IVC bland thrombus
      • 4.
        Presence of sizable patent lumbar veins distal (inferior) to cavectomy site
