It is an observational study on ruptured abdominal aortic aneurysm and abdominal compartment syndrome.

the aim of this study is to assess the qualities of a predictive score on the occurence of this syndrome after surgery of ruptured aortic aneurysm

Despite improved management techniques of ruptured abdominal aortic aneurysm, especially in vascular surgery, the mortality rate has not decreased these last years.

The abdominal compartment syndrome (ACS) has been clearly identified as one of the main etiologies of mortality after ruptured aortic aneurysm. The mortality grow up with ACS in this population.

So, the investigators want to screen abdominal compartment syndrome in the operative room.

It is an observational study on ruptured abdominal aortic aneurysm and abdominal compartment syndrome.

the aim of this study is to assess the qualities of a predictive score on the occurence of this syndrome after surgery of ruptured aortic aneurysm

Later the aim of a future study will be to screen ACS and manage patient as soon as possible to avoid it.

Inclusion Criteria:

• over 18
• to be hospitalized in participating hospitals
• ruptured aneurysm confirmed and operated

Exclusion Criteria:

• pregnancy
• patients with bladder tumor or bladder surgery or trauma bladder can distort bladder pressure measurement
• cystectomy
• patients died before arrival in the operating room
• patients died during surgery or within one hour of the initial surgical procedure
• patient whose abdominal closure at the end of the procedure is impossible

All patients with ruptured abdominal aortic aneurysm may be included in the study, whatever the surgical technique used.
