A 65-year-old gentleman was referred with progressive bilateral lower limb swelling. Investigation revealed a right renal mass with extensive venous involvement.
Contrast-enhanced CT demonstrated a 6 ร 5 ร 6 cm heterogeneously enhancing mass arising from the upper pole of the right kidney. The lesion extended into the perinephric space, invaded the upper calyceal system, and showed marked neovascularization consistent with renal cell carcinoma.
Further imaging demonstrated tumor thrombus extending from the right renal vein into the inferior vena cava and across to the left renal vein. Despite the relatively modest size of the primary tumor, the extent of venous invasion represented advanced disease and a significant oncovascular challenge.
Importantly, staging investigations demonstrated no pulmonary metastases, pleural disease, mediastinal lymphadenopathy, hilar lymphadenopathy, or other distant metastatic disease, making aggressive surgical treatment a feasible option.
Following multidisciplinary discussion, the patient was scheduled for radical right nephrectomy with caval tumor thrombectomy.
The procedure was performed through a ๐ฟ๐ฒ๐๐ฒ๐ฟ๐๐ฒ ๐-๐๐ต๐ฎ๐ฝ๐ฒ๐ฑ ๐ฎ๐ฏ๐ฑ๐ผ๐บ๐ถ๐ป๐ฎ๐น ๐ถ๐ป๐ฐ๐ถ๐๐ถ๐ผ๐ป, providing excellent exposure of the upper abdomen, retroperitoneum, liver, right kidney, and inferior vena cava.
The operation commenced with mobilization of the hepatic flexure and complete Kocherization of the duodenum to expose the retroperitoneum and major vascular structures.
The right kidney was handled with extreme care throughout the procedure to minimize the risk of tumor thrombus fragmentation and pulmonary embolization.
Following oncological principles, the right renal artery was identified, controlled, and ligated first. This reduced arterial inflow to the tumor, decreased venous congestion, and facilitated safer subsequent dissection.
The right renal vein was then controlled and divided.
Attention was subsequently directed towards the vena cava.
Complete liver mobilization was performed to expose the retrohepatic inferior vena cava. Adequate exposure of the entire caval segment was essential before proceeding with thrombectomy.
Vascular control was achieved by:
โข Control of the infrahepatic IVCโข Portal triad controlโข Suprahepatic IVC control using digital compression and stay sutures with polypropyleneโข Systemic heparinization
After secure vascular control had been established, a longitudinal cavotomy was performed.
The tumor thrombus was carefully extracted from the inferior vena cava and renal venous system while maintaining meticulous control to avoid fragmentation and potentially fatal pulmonary tumor embolization.
The nephrectomy specimen and tumor thrombus were removed en bloc and sent for histopathological analysis.
The cavotomy was repaired primarily using a double-layer continuous 4/0 polypropylene suture technique, restoring caval continuity and preserving venous outflow.
Hemostasis was satisfactory and no immediate intraoperative complications occurred.
The patient was transferred to the intensive care unit for close postoperative monitoring and subsequently made an uneventful recovery.

Renal cell carcinoma has a unique tendency to extend into the renal vein and inferior vena cava.
โ
Tumor size alone does not predict biological behavior; relatively small renal tumors may demonstrate extensive caval invasion.
โ
Radical nephrectomy with caval thrombectomy is fundamentally an oncovascular procedure requiring strict adherence to both oncological and vascular surgical principles.
โ
Early renal artery ligation reduces venous congestion and facilitates safer tumor handling.
โ
Adequate exposure is critical. Reverse L incision, complete Kocherization, and full liver mobilization provide safe access to the retrohepatic inferior vena cava.
โ
Secure proximal and distal caval control must be achieved before cavotomy.
โ
Excessive manipulation of the kidney or tumor thrombus can result in catastrophic pulmonary tumor embolism.
โ
Successful management depends on meticulous planning, vascular control, multidisciplinary collaboration, and attention to oncological principles.
โ
Extensive caval involvement is not necessarily a contraindication to potentially curative surgery in carefully selected patients.

"In advanced renal cell carcinoma, the greatest technical challenge is often not the kidney tumor itself, but the tumor thrombus extending into the vena cava. Success depends on meticulous exposure, secure vascular control, adherence to oncological principles, and prevention of potentially fatal tumor embolization."
