Madam,

We operate 180–200 renal cell carcinomas (RCCs) annually with 10–15 having vena caval extension. Literature reports embolism in 1.5% RCC with mortality as high as 75%.[1],[2] We describe a case of tumor embolism in which a catastrophic event was averted by the prompt and coordinated anesthetic and surgical intervention.

A 59 American Society of Anesthesiologist II female with a diagnosis of RCC was posted for radical nephrectomy. Magnetic resonance imaging (MRI) showed left renal mass measuring 5.2 cm × 3.7 cm abutting the inferior vena cava (IVC). Her preanesthetic evaluation was remarkable with no comorbidities. She was planned for general anesthesia with epidural analgesia and induced with intravenous propofol and morphine. The tumor was vascular, extending 3–4 cm into the IVC. The dissection went uneventful. Vascular clamps were applied on suprahilar IVC, right renal vein along with infrahilar IVC, and radical nephrectomy was performed. Left renal along with the thrombus in situ was secured in the clamp. The thrombus was retrieved from the left renal vein after releasing its clamp. After ensuring complete thrombus retrieval (by palpation of the IVC), the clamps were released. As soon as the clamp was released, there was sudden hypotension and the blood pressure dropped to 60/30 mmHg. The central venous pressure rose to 25 cm H2O. On suspicion of tumor embolism, 5000 units heparin intravenous (IV) was given. Two units of packed cell blood were transfused, and IV infusion of noradrenaline at 0.2 mcg/kg was started. The blood pressure rose to 128/75 mmHg, and a mean arterial pressure of 75 mmHg and above was maintained throughout the surgery. The arterial blood gas showed pH - 7.339, PaO2- 200, PCO2- 40.1, HCO3- 21.1, and Base excess (BE) - −4.3. The patient was extubated after complete reversal of neuromuscular blockade. Five minutes following extubation, the patient became unresponsive. There was an episode of ventricular tachycardia with hemodynamic instability which was reverted on cardioversion. The patient was re-intubated, and the hemodynamics was maintained on noradrenaline 0.2 mcg/kg/min, adrenaline 0.1 mcg/kg/min, and dobutamine 2 mcg/kg/min. The computed tomography pulmonary angiography confirmed the diagnosis of pulmonary thromboembolism [Figure 1]. The right side cardiac chambers were dilated with reflux in inferior vena cava. The patient was shifted for embolectomy. Multiple fresh and organized thrombi were removed from both right pulmonary artery, left pulmonary artery and its 2nd generation branches. The patient was extubated on day 2 and discharged on day 10 from the hospital without any sequelae.

RCC with intravascular tumor thrombus is seen in 10% cases and is associated with severe cardiopulmonary morbidity and mortality.[3]

Preoperative characterization of tumor thrombus (Level 0 thrombus limited to the renal vein, Level I <2 cm into the IVC, Level II >2 cm in the IVC below hepatic veins, Level III extends above hepatic veins but below the diaphragm, Level IV above the diaphragm, including atrium) through an MRI is required to plan intraoperative management.[4]

Vascular bypass is classically indicated in Level III or IV tumor thrombus to facilitate safe resection.[5] In our case, it was Level II tumor extension into the IVC which demands complete caval isolation with control of the infrarenal and suprarenal IVC, contralateral renal vein, and lumbar veins. As the clamp was placed on the IVC, there could have been a possibility of thrombus discharge from the lumbar veins. Aggressive surgical technique or prolonged cavotomy can also add to the risk of thrombus discharge.

Through this case report, we aim to highlight that in a patient with suspected intraoperative embolism, prompt and coordinated multidisciplinary approach can revert the catastrophic event.
