“…Thrombus Formation Combining the information obtained by transesophageal two-dimensional echocardiography and color-coded Doppler, patients (patients 1, 4, 11, 15) with remaining large communications had laminar flow within the false lumen and no or only localized thrombus formation. However, in patients where the leading intimal tear had been closed during surgery (patients 2, 3, 5) or in those with only small communications (patients 11,12,16,17,18) in the descending aorta, slowly circulating flow within the false lumen and extensive and progressive thrombus formation was observed. Thrombus formation in the false lumen was not detected by conventional echocardiography.…”

Ambulatory follow-up of aortic dissection by transesophageal two-dimensional and color-coded Doppler echocardiography.

Follow-up of 18 patients with aortic dissection (five with type I, one with type II, 11 with type III dissection according to DeBakey) by transesophageal, two-dimensional and color-coded Doppler echocardiography showed a persistence of the false lumen in five of seven patients (71%) after surgery and in nine of 11 patients (82%) after medical therapy. In two patients treated with surgery, the dissected part of the aorta had been resected, whereas in two patients treated medically, a progressive and complete obliteration of the false lumen was observed. In the false lumen, thrombus formation was absent in four, localized in four, and progressive in six patients. Flow within the false lumen could be registered in 14 patients, and two distinct flow patterns were differentiated (laminar biphasic flow or slowly circulating flow). Persisting intimal tears were visualized by two-dimensional echocardiography in four patients, whereas colorcoded Doppler showed an additional one to three intimal tears in the descending aorta in 10 patients. Flow across these intimal tears was biphasic in 75% of patients; that is, systolic flow was directed from the true to the false lumen with diastolic flow reversal. Unidirectional flow was detected in 25% of the communications, directed in 20%o from the true to the false lumen, serving as an entry only and in one (5%) as reentry only. Additional information concerning complications like extension of the dissection (one of 18 patients), localized dilatation of the aorta (two of 18 patients), mediastinal hematoma (one of 18 patients), or aortic regurgitation (three of 18 patients) were detected by this method. Concerning the morphologic findings and the detection of flow characteristics, the transesophageal approach was superior to conventional echocardiography especially in the descending thoracic aorta. Thus, transesophageal twodimensional and color-coded Doppler echocardiography seems to be an ideal method not only for the easy detection of aortic dissection but also for follow-up. (Circulation 1989;80:24-33 Transesophageal echocardiography overcomes these methodologic limitations and is of great diagnostic value because of high-quality cross-sectional images of the ascending and descending thoracic aorta even in patients in shock or on mechanical ventilation.23-30 Surgery without further diagnostic investigation has been performed successfully in emergency cases.30 In combination with color-coded Doppler flow imaging, which superimposes flow information

“…[10][11][12][13][14][15][16][17][18][19][20] Echocardiography is the method of choice for diagnosis of aortic dissection because it is less invasive and less expensive than other methods. Transthoracic echocardiography is less reliable in patients with obesity, pulmonary emphysema, or thorax deformation.…”

“…Endovascular treatments are continuously providing a third option to open surgical or percutaneous approaches. From the establishment of the Seldinger technique (Seldinger 1953) and the first use of digital subtraction angiography (DSA) (Meaney et al 1980) to the modern interventional lab with 3D road maps (Soderman et al 2005) and CT like capacities of the C-arm (Soderman et al 2008) the path has been long but rapidly progressing. The driving force up until today, that has made the leap ward style of improvements possible, is both rapid developments in computational power and material sciences.…”

“…Digital subtraction angiography was initially used primarily in the diagnosis of peripheral vascular disorders (Baert et al, 198 1;Crummy et al, 1981;Meaney et al, 1980;Pond et al, 1982;Weinstein et al, 1981). However, there are few reports in the literature to date on the use of this technique for evaluation…”

Summary:We studied 46 patients with a history of transmural myocardial infarction or angiographic evidence of coronary artery stenosis with both conventional contrast ventriculography and digital subtraction ventriculography from May to September 1982. Urografin 76@, 30 ml, was administered at a flow rate of 18 ml/s, by means of a catheter in the superior vena cava during digital subtraction ventriculography (DSV). Results of the latter were compared with conventional contrast ventriculograms. The correlation coefficient was r = 0.938 (p
