[Neoplastic caval and intracardiac thrombosis secondary to reno-adrenal tumors. One-stage surgical treatment in deep hypothermia and cardiocirculatory arrest].

Due to the considerable progress made by instrumental total body diagnostics (ECO, CAT, RMN, angiography, etc.) in recent years heart surgery has increasingly often been used to treat pathologies which are not primarily cardiac but which see the involvement of the heart and large vessels in the advanced stages of cancer and non-cancer diseases of other organs or apparatus. This is the case of malignant renal or adrenal tumours which infiltrate along the caval lumen until they reach the right atrium. In these cases caval and atrial involvement must be seen as a prolapse of the tumour and not a long-distance metastasis: prognosis only appears to be linked to the hemodynamic impairment caused by the obstacle to systemic lower venous drainage. On the bases of this observation radical surgery may be justified at a renal, caval and cardiac level. The authors report their preliminary experience in 6 patients with renal cancer (4 renal carcinoma, 1 Wilm's tumour, 1 adrenal carcinoma) who underwent combined surgery, in a single stage, involving enlarged nephrectomny and caval and atrial thrombectomy, the latter performed in profound hypothermia and cardiocirculatory arrest. Two patients died later and 4 are living, in good condition and with perviousness of the lower caval venous drainage. Similar to other analogous experience reported in the literature, the authors suggest taking a combined approach performed in a single stage into consideration for these patients.
