Inferior vena cava (IVC) syndrome is a cluster of symptoms that occur due to obstruction or stenosis of the inferior vena cava. Symptoms include lower extremity swelling and erythema, shortness of breath, and abdominal discomfort. This case describes a patient who presented for evaluation of lower extremity swelling and weakness associated with nausea and vomiting. A plan was made to investigate a cardiopulmonary etiology; however, the initial bedside ultrasound that included the evaluation of the abdomen discovered a mass in the IVC and left kidney. Additional imaging and intervention that involved a posterior radical nephrectomy and IVC thrombectomy allowed confirmation of left renal cell carcinoma (RCC) extended into the IVC with a thrombus causing the constellation of symptoms. A detailed history is always important to configure the IVC syndrome, but a quick and easy bedside ultrasound can identify IVC and other abdominal pathologies. A multidisciplinary approach is highly recommended for optimal results.
下腔静脉（IVC）综合征是一组由于下腔静脉阻塞或狭窄而出现的症状。症状包括下肢肿胀、红斑、呼吸急促和腹部不适。本病例描述了一名因下肢肿胀、无力伴恶心呕吐前来评估的患者。最初计划调查心肺病因；然而，最初包括腹部评估的床边超声检查发现下腔静脉和左肾有一个肿块。进一步的影像学检查和包括后根治性肾切除术及下腔静脉血栓切除术在内的干预措施证实了左肾细胞癌（RCC）已扩展至下腔静脉并伴有血栓，从而导致了一系列症状。详细的病史对于诊断IVC综合征始终很重要，但快速简便的床边超声检查可以识别下腔静脉和其他腹部病变。强烈建议采用多学科方法以获得最佳结果。
