Brief Summary
The investigators hypothesize that a primary embolization, 3-4 weeks before surgery, would allow development of vascular collaterality, in particular for the marginal artery which will ensure a better colonic perfusion.

Eligibility Criteria
You may qualify if:
- The patient must have given their free and informed consent and signed the consent form
- The patient must be a member or beneficiary of a health insurance plan
- The patient is at least 18 years old and less than 80 years old
- Patient has rectal cancer or sigmoid colon cancer requiring surgical treatment
You may not qualify if:
- The subject refuses to sign the consent
- It is impossible to give the subject informed information
- The patient is under safeguard of justice or state guardianship
- Patient has a history of abdominal surgery
- Patient suffers from a hemostasis disorder (hemophilia, von Willebrand disease, thrombocytopenia) and is on anticoagulant therapy.
- Patient whose general condition appears too precarious or is taking corticosteroids or immunosuppressants leading to an unacceptable surgical risk.
- Renal insufficiency with clearance \<45ml / min
- Known allergy to contrast media
- Patient who had treatment of the abdominal aorta or its branches Reported pregnancy (the existence of effective contraception will be verified for women of childbearing age).
- Anatomical variant at risk or absence of marginal artery highlighted at the time of arteriography.
- Abnormality of the superior mesenteric artery
