Beskrivelse
Inclusion Criteria:
- patient whose age is ≥ 18 years old
- any patient seen more than 6 months and less than 5 years after a dissection involving the descending aorta at Bichat Hospital, whether it is a dissection of the descending aorta alone or a dissection of the ascending aorta extended to the descending aorta
- dissection of the uncomplicated descending thoracic aorta: not requiring surgery or stent implantation within the first 6 months after acute dissection
- effective contraception for women of childbearing age
Exclusion Criteria:
- scheduled procedure for dissection of the descending aorta
- contraindication to aortic CT with injection of contrast media: renal failure with creatinine clearance <30 ml/min or creatinine >200 µmol/l; allergy to contrast media
- history of surgery or stent implantation in the descending thoracic aorta
- pregnant or breastfeeding women
- patient under guardianship or trusteeship
- non affiliation to social security or CMU (beneficiary or assignee)
- patient refusal to participate in the study

Correlation between the rate of expansion of the aortic diameter and the intensity of attachment of the annexin by the aortic wall descending
Tidsramme: 30 months
|
Pearson correlation coefficient between the rate of expansion of the aortic diameter measured by CT (at 6 months, 18 months and 30 months) in mm/year (at the site of maximum expansion) and the intensity of attachment of the annexin by the aortic wall descending in scintigraphy.
