Computed tomography angiography-negative aortic dissection in a patient using Phencyclidine

Abstract

Although the average age of diagnosis for aortic dissection is 63, [1] this case demonstrates the need to consider AD in younger patients, particularly in the presence of risk factors or in the absence of another reasonable diagnosis. This case suggests PCP use as a precipitant for hypertension and sympathomimetic stress on the aorta. Despite high sensitivity, false negative CTA imaging for AD can occur. If pretest probability remains high, further imaging must be obtained. During resuscitation in the ED, focused point-of-care ultrasound can also assist with medical decision making. Funding: None.

Mini Aortic Valve Replacement Converted to Bentall Procedure Secondary to Chronic Type A Aortic Dissection

“…Although computed tomography angiography is the gold standard for diagnosing acute aortic dissection, sometimes there can be false negatives, although the rate of false negatives is extremely low. The sensitivity and specificity of computed tomography angiography to identify acute aortic dissection range from 94% to 100% and 77% to 100%, respectively [ 3 ].…”

Diagnostic value of dynamic computed tomographic angiography for aortic dissection and the perfusion of involved organs

“…Despite that CTA has 100% sensitivity and 98% speci city for AD [10,11], false-negatives can still occur [12,13]. Nevertheless, recent aortic vascular imaging dynamic scanning methods have been put into clinical use to generate dynamic vascular "cine series" to observe the hemodynamic changes in AD [14][15][16][17][18].…”

Are radiological modalities really necessary for the long-term follow-up of patients having blunt solid organ injuries? A single center study

“…[9] MDCT had become the standard choice of modality at the most institutions for the evaluation of abdominal injuries for its highly accurate diagnostic quality and short acquisition time. [10][11][12] On the contrary, the facts of contrast-induced nephropathy with radiation exposure start the discussions about its liberal usage limiting to certain cases.…”
