RESUMO
Intracardiac tumor extension from nephroblastoma is a rare event. We report on two cases with this peculiar condition who presented with a different set of signs and symptoms. Both were diagnosed in life but only one could be properly managed on time. Emphasis is made upon the most reliable methodology for early detection and the surgical approach as the only plausible way to solve this particular complication.

In order to investigate the possible unwanted late effects of vessel cicatrization during growth, especially after the section and terminal-terminal arterial anastomosis, a study was carried out in 28 piglets using three different surgical anastomosis techniques as well as three different types of sutures. Results show that the smaller the diameter of the vessel and when for its surgical correction suture techniques using separate and combined stitches are used, in addition to non absorbent material, a greater amount of suppression is seen at the site of anastomosis during arterial growth. Less suture material is recommended (of lesser thickness) as well as continuous suture techniques as the diameter of the vessels to be sutured decrease.
