Study of the Size of the Operating Fields Depending on the Morphology of the Patients

This is a prospective, single-centre, observational clinical study.

Patients who have not expressed their non-opposition, who are of age and who are undergoing open surgery on the abdominal aorta by laparotomy will be included.

The aim is to mathematically model the working volume for abdominal aortic surgery as a function of the preoperative CT scan, the length and orientation of the incision and the morphometric characteristics of the patient, and thus predict the surgical risk.

To meet this objective, the dimensions of the working volume of open abdominal aortic surgery will be measured using a camera to create an algorithm by associating them with the preoperative images and morphometric data of the patient.

Treatment and study plan

open surgery on the abdominal aorta by laparotomy

Procedure

Laparotomy aortic surgery for the management of an abdominal aortic aneurysm has several distinct stages which will not be altered by the performance of this study. The patient arrives in the operating room and is taken care of by the anesthetic team. The patient is then placed in the correct position for optimal surgical management and a skin cleansing procedure is carried out. A sterile drape is applied and the preoperative checklist in force in the establishment is completed. Initial dissection of the aneurysm and its proximal and distal control is left to the discretion of the principal surgeon. Once the aortic aneurysm has been controlled, the main surgeon places self-static retractors and then prepares to clamp the aorta. The surgeon initiates aortic clamping to create the aorto-biliac or bifemoral bypass. Once the bypass has been created, the operation is completed by closing the surgical approach and the skin incision. The bandage is then applied.

Primary outcomes

Mathematically model the working volume for abdominal aortic surgery as a function of the preoperative CT scan, the length and orientation of the incision and the morphometric characteristics of the patient, and thus predict surgical risk.
