NCT03628248

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

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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:

  • 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.
