Renal cell carcinoma (RCC) represents 2%–3% of all cancers. Surgical management is preferred in these patients. These cases present with unique anesthetic challenges and complications. However, with appropriate workup and intraoperative anesthetic management, the surgery can be successfully contemplated without any complications.
A 55-year-old male patient presented with a history of pain in the right lower back of 3 months' duration followed by hematuria of about a month's duration. There were no associated comorbidities. He was evaluated with abdominal ultrasound, computed tomography scan, followed by magnetic resonance imaging and whole-body positron emission tomography scan confirming the diagnosis of right RCC with tumor thrombus extending into right renal vein and infradiaphragmatic inferior vena cava (IVC).
The patient was planned for right radical nephrectomy with thrombectomy. A high-risk consent for the surgery was taken and cardiopulmonary bypass was also kept standby. All the hematological investigations except serum urea (68 mg/dL) and creatinine (2 mg/dL) were within normal range. The surgical plan was laparotomy, and hence, the anesthetic plan was endotracheal intubation with invasive monitoring and epidural analgesia.
All the baseline parameters were within normal limits. Epidural catheter was inserted at T7–T8 level using an 18-gauge Tuohy needle. The patient was intubated using injection propofol and injection pancuronium. Left femoral artery and right internal jugular vein were cannulated. Balanced anesthesia was maintained using opioids and inhalational agents.
The intraoperative course was hemodynamically stable, except when the IVC was clamped during thrombectomy. This hypotension was anticipated and managed with injection noradrenaline 0.03–0.05 mcg/kg/min.
The surgery lasted for 8 h; the patient was not extubated and placed on postoperative mechanical ventilation. As the patient remained hemodynamically stable, he was extubated next morning after appropriate weaning trials.
Intraluminal extension of RCC into IVC occurs in 4%–10% of all the patients. For removal of a large thrombus in the supradiaphragmatic IVC or atrium, cardiopulmonary bypass either with or without deep hypothermic circulatory arrest is appropriate. Cardiopulmonary bypass can be avoided by using transesophageal echocardiography imaging to guide the manipulation of a vena caval balloon.
In this patient, the tumor thrombus extraction was done using balloon extraction technique. Cardiopulmonary bypass, though kept ready, was not required during the surgery.
Another anesthetic consideration is the intraoperative blood loss. Blood loss in RCC with level III IVC thrombus may be of the range 100–5000 mL (mean 500 mL). In our case, the loss was approximately 1.5 L and was appropriately managed using crystalloids (3500 mL) and blood products (1000 mL).
Intraoperative hypotension which commonly appears as a result of blood loss should be tackled using intravenous fluids and vasopressors. Central venous pressure and hourly urine output monitoring can be used to achieve desired hemodynamic goals, as was done in this case.
Successful anesthetic management of RCC with IVC thrombus requires meticulous monitoring, anticipating, and appropriately managing the possible complications.
