Multiple Primary Synchronous Renal Cancer and Thyroid Gland Cancer at Patient with Doubling Inferior Vena Cava and Renal Veins on Both Sides (Clinical Case)

Renal cell carcinoma – the third on occurrence frequency tumor of urinogenital system and the most widespread renal tumor which makes about 2–3% of malignancies at adults. Doubling of inferior vena cava (IVC) is anomaly in case of which two inphrarenal segments of IVC are defined. Left IVC after lockin in it the left renal vein crosses an aorta in front, connects to the right renal vein and the right IVC. Combination of renal cell carcinoma and doubling IVC is rather seldom. The presented clinical case of a combination of renal cell carcinoma and doubling of IVC has the feature existence at the patient of metachronous multiple primary neoplasms that does necessary more careful inspection of the patient. Also a doubling of renal veins on both sides and a doubling of the left renal artery have been revealed. Possibilities of presurgical non-invasive diagnostics (ultrasonography and computer tomography) of retroperitoneal space vessels anomaly at the patient with transmural localization of kidney tumor allowing to plan and execute difficult surgery – an ex vivo resection of a left kidney in the conditions of pharmacological cold ischemia was shown. Performance of an ex vivo nephrectomy in the conditions of pharmacological cold ischemia allows to dilate indications to organ-preserving treatment of patients with the localized kidney cancer. However long cold ischemia and the subsequent vascular reconstruction demand dynamic observation over kidney’s functional conditions.
