The literature has been reviewed, and 58 autopsied cases of dissecting aneurysm of the aorta observed at the Los Angeles County Hospital over a ten year period have been carefully studied. Clinical-pathologic correlation has been attempted whenever possible, with emphasis on diagnostic features. The increasing incidence of accurate diagnosis of dissecting aneurysm has been noted, and it is hope...

Subarachnoid hemorrhage from dissecting vertebral artery aneurysms is a well-known phenomenon. With the advent of navigable intracranial stents, these aneurysms are now amenable to endovascular stent placement. However, immediate aneurysm obliteration is often not accomplished, and current covered stents have poor short-term patency rates. We report a series of three patients with intradural di...

Dissecting aneurysm is the cause of about ona in a hundred of sudden deaths and about one in four hundred of all hospital deaths. Men are affected much more commonly than women in a proportion of between two and three to one, except in extreme old age when the sex difference is less, partly because there are more old women than old men. Dissecting aneurysm can occur at any age. The heaviest inc...

A 64-year-old male presented with subarachnoid hemorrhage. Angiography showed a dissecting aneurysm of the right vertebral artery (VA), and severe stenosis of the right internal carotid artery (ICA). He was treated conservatively in the early stage. Repeat angiography showed enlargement of the dissecting aneurysm of the VA and partial resolution of the stenosis of the right ICA. Intraaneurysmal...

Among 119 cases of fatal dissecting aneurysm of the aorta, exclusive of those iatrogenically caused or associated with arachnodactyly or aortic stenosis, there were observed 11 cases of congenital bicuspid aortic valve (9%). The ages ranged from 17 to 69 years, five of the patients being 29 years old or younger. Among the latter, three had coarctation of the aorta and one had Turner's syndrome ...

Dissecting aneurysms of the vertebrobasilar system are infrequent. Most of the commonly reported cases describe iatrogenic or traumatic aneurysms of the extracranial vertebral artery. Spontaneous dissecting aneurysms of the extracranial vertebral artery are frequently associated with carotid artery lesions; however, such association is poorly documented in the literature. We describe a case of ...

Intramyocardial dissecting haematoma is a rare form of cardiac rupture that can occur as a complication following acute myocardial infarction or during the remodelling process. It is usually caused by a haemorrhagic dissection among the spiral myocardial fibres and needs urgent surgical treatment. Here we report the case of a 67-year-old man with indications of a previous infarction, in whom a ...

AORTOGRAPHY by translumbar, retroIAJL grade femoral injection, and retrograde catheterization, are all now considered moderately safe and efficacious diagnostic procedures. It is our objective to describe a potential hazard in retrograde arterial catheterization for the diagnosis of dissecting aneurysm, that to our knowledge, has not previously been described. Two cases are presented in which t...

Intramyocardial dissecting hematoma is a rare but potentially fatal complication of myocardial infarction. The decision to adopt a surgical or conservative strategy may depend on the clinical and hemodynamic stability of patients. Regardless, the precise and temporal assessment of the structure of hematoma is imperative. We herein report the first case of a patient with early spontaneous remiss...

A patient with a dissecting thoracic aortic aneurysm presented with acute low output cardiac failure due to right atrial obstruction. Five years earlier she had had her aortic valve replaced because of aortic regurgitation. Obstruction of the superior vena cava and pulmonary artery has been reported elsewhere as a complication of compression by thoracic aortic dissecting aneurysm. This case was...
