Abstract    Retroperitoneal tumors involve major blood vessels in abdominal and pelvic cavity and increase the risks of surgical resection. A scant resection of retroperitoneal tumor is easy to damage blood vessel and lead to severe hemorrhage, even death. The mastery of the techniques and principles of vascular reconstitution could help to improve the resection rate and life expectancy of complex retroperitoneal tumor.
