The clinical diagnosis of a ruptured aortic aneurysm is unreliable, and in haemodynamically stable patients both ultrasound and CT are used to improve diagnostic accuracy. In any patient with a suspected ruptured aneurysm, ultrasound is done upon arrival of the patient in the hospital to confirm or exclude the presence of an aortic aneurysm. If facilities for endovascular reconstruction are available at the hospital, an immediate CT scan with intravenous contrast follows, to find out if and how endovascular treatment should be performed. If endovascular reconstruction is not available, a CT scan without using contrast is carried out. If the CT scan shows a ruptured aneurysm, the patient is transported to the Operating Department without further delay. If the CT scan does not show any signs of rupture, there is time for further investigation. If no alternative condition to explain the patient's symptoms is found, further diagnostic tests such as repeat ultrasound, CT with contrast material and laboratory tests can be performed. If no other serious condition emerges, the aortic aneurysm should be considered symptomatic. In this case, the patient should undergo a rapid, but thorough pre-operative work-up, and go for operation as soon as possible by a rested and experienced operating team as part of the regular day programme.
