    Azygos venous pathway (AVP) status can help identify patients at high risk for massive hemorrhage during renal cell carcinoma surgeries.

  • 2

    Radical nephrectomy and tumor thrombectomy (RNTE) is a complex procedure with significant intraoperative hemorrhage risk, averaging 1900 ml blood loss.

  • 3

    Minimally invasive RNTE techniques generally result in lower blood loss compared to open procedures, but massive hemorrhage risk remains.

  • 4

    The study quantifies the compensatory state of the azygos-hemiazygos pathway to aid in preoperative surgical planning for RCC patients.

  • 5

    Understanding AVP's role in venous drainage may improve surgical outcomes by reducing intraoperative bleeding during RNTE.
