Radical nephrectomy and intracaval thrombectomy for advanced renal cancer with extensive inferior vena cava involvement utilising cardiopulmonary bypass and hypothermic circulatory arrest: Is it worthwhile?

摘要

ObjectiveTo report our long-term outcomes of surgical treatment of renal tumours with inferior vena cava (IVC) tumour thrombus above the hepatic veins, utilising cardiopulmonary bypass (CBP) and hypothermic circulatory arrest (HCA), as surgical resection remains the only effective treatment for renal cancers with extensive IVC tumour thrombus.Patients and methodsWe retrospectively reviewed 48 consecutive patients (median age 58?years) who underwent surgical treatment for non-metastatic renal cancer with IVC tumour thrombus extending above the hepatic veins. Perioperative, histological, disease-free (DFS) and overall survival (OS) data were recorded.ResultsTumour thrombus was level III in 23 patients and level IV in 25 patients. The median (range) CBP and HCA times were 162 (120–300)?min and 35 (9–64)?min, respectively. Three patients underwent synchronous cardiac surgical procedures. There were three (6.3%) perioperative deaths. American Society of Anesthesiologists grade and perioperative blood transfusion requirement were significant factors associated with perioperative death (P?
