The pelvis and groin contain a complex web of blood vessels. Given the magnitude of resection often needed when treating pelvic malignancies, it is not uncommon to be faced with the need to address major vascular issues. These fall into three general categories: inadvertent injuries requiring repair; planned resection as part of tumor excision, requiring reconstruction; and caval interruption to prevent pulmonary embolism.

It should be remembered that preservation of life through control of hemorrhage takes priority over preservation of blood flow to the limbs.
