Color Doppler evaluation of aortic dissection.

Abstract

748-755, 1987. PROGNOSIS of patients with aortic dissection is determined by several factors: duration of dissection at the time of diagnosis, location of intimal tear, site and extent of the dissection, presence or absence of blood flow in the false lumen, presence of pericardial effusion and tamponade, and presence and severity of aortic regurgitation.' Therefore, since the survival rate and consequent therapeutic approach of patients with aortic dissection is influenced by both anatomic and flow conditions, an easy, repeatable technique capable of assessing this lesion noninvasively would be of great clinical usefulness.An accurate morphologic evaluation of the dissecting process is obtainable with different cardiac imaging techniques such as cineangiography,68 computed tomography, 91 magnetic resonance imaging, and two-dimensional echocardiography. 12-15 Among these imaging techniques, cineangiography is the only one that also provides data on blood flow conditions in both true and false lumina; however, because of its invasive nature and the need to inject a certain amount of contrast material during fluoroscopy, it is not suitable for serial evaluation of patients with dissection. Two-dimensional Doppler color flow mapping (color Doppler)`2 is a recently developed ultrasound techFrom the Cardiology Divisions, University of Bari, Italy, and the

Ambulatory follow-up of aortic dissection: comparison between computed tomography and biplane transesophageal echocardiography

“…Our data confirm and extent previous evidences suggesting that TEE is an excellent option not only for the detection of aortic dissection [17][18][19][20] but also for follow-up of treated patients, with an accuracy at least comparable to that of CT [ 11 ].…”

Doppler color flow imaging of common carotid artery dissection

“…In 14 of a group of 16 patients with aortic dissection color Doppler provided a display of oppositely directed blood flow in the true and false lumina of the aorta, and the site of communication between the two lumina could be identified [13]. To our knowledge the results of DCFI in a CCA dissection have not yet been reported, but our findings correspond with those from color Doppler examination of aortic dissection.…”

Dissecting aneurysm of the superior mesenteric artery: flow dynamics by color Doppler sonography.

“…Reversal of flow in the false lumen has been identified on color Doppler sonography in dissecting aneurysms of the aorta 8 and carotid artery. [9][10][11] Kotval, in an analysis of the flow dynamics in a carotid artery dissection, attributed reversal of flow in an SMA aneurysm, such as we described in our case, to a to-and-fro excursion of the intimal flap, resulting in a reciprocally varying resistance to flow in the two lumina.…”
