Introduction: Splanchnic vein thrombosis (SVT) is rare in the general population. It often occurs in the context of liver cirrhosis. The association between clear-cell renal cell carcinoma and splanchnic vein thrombosis is very rare, and most data come from case reports. We surgically treated a 53-year-old man who presented with a left middle renal tumor with extensive venous thrombosis of the portal vein extended to the superior mesenteric vein and its collaterals, we also provided a brief review of the literature on this topic. Conclusion: SVT is rare, especially in the absence of liver pathology. There is a well-defined relationship between cancer and thrombosis, but the association between clear-cell renal cell carcinoma and DVT is poorly described. The management of DVT must be individualized, assessing the benefits and risks in each case. Early anticoagulation combined with local treatment of the tumor improves recanalization of splanchnic vein thrombosis.
