Official title: Prospective Feasibility Study of Point-of-care Ultrasound in Suspected Aortic Dissection

Status Not yet recruiting

Clinical Trial Summary

Aortic dissection is an uncommon and serious pathology. Its diagnosis is difficult because of the varied and silent clinical presentations. The development of ultrasound in emergency medicine is an asset in certain pathologies. The aim of this study is therefore to study the feasibility of a protocol integrating clinical ultrasound in the suspicion of acute aortic dissection in the hospital setting. This study is a single-center prospective interventional study. In which the investigators perform ultrasound in patients with suspected acute aortic dissection in the emergency department. If the protocol is feasible and if it allows a saving of time in the diagnosis or an increase in diagnoses, the investigators will be able to evoke a profitability to the systematic realization of this examination.

Clinical Trial Description

H0: patient selection and inclusion:

• Presentation of the study

• Delivery of the information note / no objection to the patient if he/she is in a state to consent

• Emergency procedure:

In accordance with article L-1122-1-3 of the public health code, patients may be included in the study at the initiative of the physician without seeking prior consent. This procedure will be associated with a prior call to the relatives to obtain an oral consent in principle (traced in the patient's medical file), while waiting for the delivery of the information note / no objection to the relatives and then to the patient as soon as his condition allows it.

H1: inclusion interview then :

Medical interrogation (retrospective collection if already done / but additional requests if missing data).

Clinical examination (complementary if missing data).

Ultrasound with 3 ultrasound sections to be performed: parasternal long axis, supra-sternal and abdominal, looking for the following signs:

Direct signs: presence of an intimal flap, intramural aortic hematoma > 5mm, penetrating aortic ulcer.

Indirect signs: pericardial effusion, aortic dilatation ≥ 4 cm, tamponade (1).

H4: retrospective collection of the results of complementary examinations if any, biological and radiological, and collection of the final diagnosis retained. ;
