Abstract: | A 30-year-old female was admitted to our hospital with a 3-month history of general fatigue and one month history of left flank mass. Computed tomography revealed a huge left renal tumor (20 × 13 × 10 cm) with intracaval tumor thrombus. The tumor thrombus extended into the right atrium. The left renal vein (lt-RV) was expanded 3.5 cm in diameter by the tumor thrombus. The tumor was surrounded by a tortuous dilated capsular vein. The strategic issue was how to ligate the left renal artery (lt-RA) behind the expanded lt-RV. We first divided the lt-RV occluded by the tumor thrombus using a Linear Cutter? and then divided the lt-RA before the dissection of the tumor to avoid excessive bleeding. Even transarterial embolization of lt-RA were to be performed,the tumor was too large to dissect without division of lt-RV and lt RA. After the left kidney was removed,the lower half of the tumor thrombus was excised,clamping the inferior vena cava,three right renal arteries,two right renal veins,and the lumber vein. Finally,we removed the upper half of the tumor thrombus extending to the right atrium through atriotomy and cavotomy under an extracorporeal cardiovascular bypass. Operation time was 9 h 22 m,and total blood loss was 1670 ml. Convalescence was uneventful except for abdominal lymphocele. |
