As part of oncologic visceral surgical operations the surgeon is confronted with anatomical barriers. In particular abdominal sarcomas and carcinomas sometimes require a vascular surgical procedure in order to achieve a radical and curative treatment. By using vascular surgical techniques there is the possibility for oncology patients to expand the boundaries of operability and to allow a long tumor-free survival. For each affected arterial and venous structure there are special reconstruction methods which require an optimal vascular graft. The aim of vascular resection and reconstruction should focus not only on the radicality of the operation but should also take the optimal circulation recovery of blood in the tumor resected area into account.
