Tumores renais e adrenais com invasão cardíaca: resultados cirúrgicos imediatos em 14 pacientes
BACKGROUND: The resection of tumor thrombus of the inferior vena cava (IVC) and right atrium (RA) increases the survival rate of patients with renal/adrenal cancer. OBJECTIVE: To evaluate the surgical procedure in cases of IVC and RA in the treatment of renal and adrenal tumors. METHODS: Fourteen pa...

| Sumario: | BACKGROUND: The resection of tumor thrombus of the inferior vena cava (IVC) and right atrium (RA) increases the survival rate of patients with renal/adrenal cancer. OBJECTIVE: To evaluate the surgical procedure in cases of IVC and RA in the treatment of renal and adrenal tumors. METHODS: Fourteen patients undergoing surgical intervention (during the period) between January 1997 and June 2007, for resection of IVC and/or RA thrombus due to renal or adrenal tumors, were retrospectively evaluated. The patients (64.2% male) presented with Wilms' tumor, clear cell carcinoma and adrenal adenocarcinoma, and had mean age of 4.5, 60.5 and 2.5 years, respectively. Epidemiological characteristics and intra- and postoperative parameters were evaluated. RESULTS: Suprahepatic IVC tumor thrombus were observed in all the patients, and in 62.4% of them the thrombus invaded the RA. Thrombectomy was performed with extracorporeal circulation with deep hypothermia and total circulatory arrest in 85.7%, with mild hypothermia in the remaining cases. The inferior vena cava was ligated in 7.1% of the cases, and reconstruction with suture was performed in 92.9% of the patients. The duration of orotracheal intubation and length of hospital stay were different, according to the tumor type. Two deaths, due to intraoperative cardiorespiratory arrest, were seen among patients with adrenal adenocarcinoma. CONCLUSION: IVC and RA tumor thrombi are more frequent in patients with Wilms' tumor. More postoperative complications are seen in patients with adrenal adenocarcinoma, and the postoperative prognosis is better for patients with Wilms' tumor. |
