RIOJA ZUAZU, J. et al. Extracorporeal circulation and hypothermy surgery in tumors with vena cava extension: 20 years experience at the University Clinic Of Navarra. Actas Urol Esp [online]. 2008, vol.32, n.4, pp.396-403. ISSN 0210-4806.

Objective: We present our 20 years experience treating patients with vena cava extension in whom an extracorporeal circulation, hypothermia, cardio circulatory arrest (ECC-H-CCA) in order to perform, together with a tumoral resection, a thrombus resection. Material and Methods: From 1985 to 2005 a total of 28 retroperitoneal tumor were treated: 25 renal cancers, a Wilms tumor, a paratesticular rabdomiosarcoma, and a pheocromocitoma. All of them had an extension by means of thrombus above the suprahepatics veins. All of them were treated by means of ECC-H-CCA for thrombus extraction. A descriptive study of the serie is performed as well as a Kaplan Meyer survival study. Results: Surgical complications were present within 10 patients (35%), with a surgical mortality of two patients (7%): one intra-operatively because a massive embolism of the lungs and the other because of a lung embolism on the 4^th post-operative day. Global actuarial survival was 29.1±10% at three years and 17,5±8% at five years. Analyzing only who do not have metastatic lesions, nor lymph nodes at diagnosis their three year survival was 50,9±16,3% and 32,2±16% at five years. Mean while those who have any metastatic lesion at diagnosis their three and five years survival was 20,8±12% and 10,4±9% respectively. Conclusions: The employ of surgical techniques with ECC-H-CCA with in oncological pathology associated with vena cava thrombus is justified and its employment does not worsen the survival; it is indicated because its results, allowing a complete tumoral resection in a safe and reproducible fashion.
