Traumatic dissecting aneurysms.
Most dissecting aneurysms of the aorta are spontaneous, and have as their underlying pathology a degeneration of the media. Strain, physical and mental, has been suggested as a factor which precipitates their onset, but external trauma is usually exonerated. Shennan (1934) traced only six cases due to trauma, and he formed the opinion that there was rarely a clear relationship between these ane...
متن کاملChronic Dissecting Aneurysms.
In 1939 East was able to find records of only 27 instances in which the diagnosis of dissecting aneurysm had been made during life. Usually death from complete rupture of the aorta quickly follows the initial dissection; of the 300 cases collected by Shennan (1934) 210 died within a week and survival for more than a year was recorded in only 16 cases. We have, therefore, thought it desirable to...
متن کاملDissecting aneurysms of the aorta.
Up to 1934 only six of the 300 cases of dissecting aneurysm of the aorta described in the literature had been diagnosed ante mortem (Shennan, 1934). Many correctly diagnosed cases have since been reported (with decreasing pride) and the condition is now well enough recognized in general medical practice for cases to be reported only when they present some unusual or particularly instructive fea...
متن کاملExperimental model of dissecting aneurysms.
BACKGROUND AND PURPOSE The pathogenesis and optimal treatment for arterial dissection are still unclear. We devised an experimental model of arterial dissection and observed the morphologic changes with angiography. METHODS Sixty-four experimental dissections were created in the common carotid arteries of 34 mongrel dogs. After a small incision was made in the arterial adventitia, it was diss...
متن کاملIntracranial dissecting aneurysms in childhood.
Children presenting after trauma with headache, seizures, hemiplegia and coma may have an intracranial dissecting aneurysm. Specific angiographic findings provide confirmation of this diagnosis. The dissection occurs subintimally and differs clinically and pathologically from dissecting aneurysms of extracranial arteries. The course in children beyond infancy is catastrophic, justifying conside...
