Two cases of the posterior fossa dissecting aneurysm associated with a double origin of the posterior inferior cerebellar artery (DOPICA) causing subarachnoid hemorrhage are presented. After observing a relationship between the aneurysm and DOPICA on a three dimensional rotational angiogram (3DRA), the dissecting aneurysms were successfully obliterated by surgical trapping and endovascular inte...

Conclusion These 2 case reports emphasize the difficulties of the neuro-radiological diagnosis and of the decision-making for the management of hemorrhagic dissection of the ACA. The second patient was surgically treated but, unfortunately, the wrapping of the dissected arterial wall could not prevent the recurrence of the hemorrhage. On the other hand, the follow-up showed that the dissection ...

Sections of the ascending aorta of 27 cases of dissecting aneurysm were compared histologically with the ascending aortae of 27 age- and sex-matched normotensive controls and 27 age- and sex-matched hypertensive controls. Elastic fragmentation and loss was seen to a similar degree in each series. Strip-like areas of muscle necrosis appeared to be associated as much with hypertension as with dis...

Internal carotid artery (ICA) trapping can be used for the treatment of giant intracranial aneurysms, blood blister-like aneurysms, and fusiform dissecting aneurysms. Fusiform dissecting aneurysms are challenging to treat surgically and endovascularly because of no definite neck and critical perforators. Surgical or endovascular trapping of the ICA with or without an extracranial-intracranial b...

Dissecting aneurysm of the internal carotid artery, without preceding trauma, is a rare event. We have been unable to find a previous case report. One case of dissecting aneurysm of the internal carotid artery following head injury has been reported (Dratz and Woodhall, 1947), and two cases after carotid puncture for arteriography (Sirois, Lapointe, and Cote, 1954; de Grood, 1954) where the com...

Spontaneous dissecting aneurysm of the aorta in man is most commonly a sequel of hypertension but sometimes occurs in association with degenerative liquefaction of the media of the aorta. New light has been thrown upon dissecting aneurysm by its production in growing rats by a diet high in sweet peas. The offending agent has been isolated and a number of simpler related compounds have been synt...

An analysis based upon necropsy figures has been made of the frequency of deaths with dissecting aneurysms and ruptured fusiform or saccular aortic aneurysms. More deaths from these conditions were found at necropsies conducted on people dying suddenly in the community than in those dying in hospital. Dissecting aneurysms were nearly all found to involve the thoracic segment of the aorta and we...
