1/22. Severe pulmonary hypertensive vascular disease in two newborns with aneurysmal vein of galen.Arteriovenous malformation of the vein of Galen (AVG) is a rare entity in the newborn with a high morbidity and mortality. We present two cases of fatal AVG with persistent pulmonary hypertension of the newborn and significant pulmonary hypertension documented by autopsy histopathology. The pathophysiology is reviewed and a proposed mechanism of the association between AVG and pulmonary hypertension is discussed.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
2/22. Focally increased activity on scinticisternography: report of two cases.Two cases where focally increased activity was noted on scinticisternography are reported. One case involves a documented arteriovenous malformation, and the other, documented embolic vascular disease. After a review of the pertient literature, various other pathologic entities associated with similar scan findings are described. Possible causative mechanisms are discussed.- - - - - - - - - - ranking = 0.25keywords = vascular disease (Clic here for more details about this article) |
3/22. Hemodynamic analysis of an adult vein of Galen aneurysm malformation by use of 3D image-based computational fluid dynamics.We applied computational fluid dynamic (CFD) analysis on the numerical grid of a 3D rotational digital subtraction angiogram obtained in a 22-year-old male patient, with an accidentally discovered vein of Galen malformation associated with single feeder aneurysm, to understand the flow pattern through the two aneurysms and improve our general understanding of hemodynamic characteristics of this variety of fusiform aneurysm. This technical note provides a good example of the application of CFD to 3D digital subtraction angiography for studying the flow pattern in patients with cerebrovascular disease.- - - - - - - - - - ranking = 0.25keywords = vascular disease (Clic here for more details about this article) |

5/22. Chronic paroxysmal headache: two cases with cerebrovascular disease.Paroxysmal headaches often occur in benign headache disorders such as episodic cluster headache, chronic paroxysmal hemicrania (CPH) and episodic paroxysmal hemicrania. We report 2 patients with paroxysmal headaches occurring in association with cerebrovascular disease. The first patient had paroxysmal headaches from an arteriovenous malformation which resolved following embolization. In the second patient, headache followed a cerebral infarction and responded to treatment with indomethacin. We suggest that vascular disease may cause paroxysmal headaches resembling CPH. patients with an atypical presentation of CPH warrant a neuroimaging procedure.- - - - - - - - - - ranking = 1.5keywords = vascular disease (Clic here for more details about this article) |
6/22. Inadvertent foreign body embolization in diagnostic and therapeutic cerebral angiography.BACKGROUND AND PURPOSE: Inadvertent foreign body embolization is a rarely diagnosed and neglected complication of cerebral angiography that has not been studied systematically. methods: We undertook a comprehensive 5-year retrospective study of all available postmortem cases of postangiographic neurologic complications, as well as a comprehensive histologic examination of all surgically resected central nervous system arteriovenous malformations, at our institution. RESULTS: Among the autopsy series, we found 3 patients for whom cerebral infarction, sometimes catastrophic, is attributable to inadvertent cotton fiber, Gelfoam, or polyvinyl alcohol particulate emboli during cerebral angiography. All cases described had concurrent atherosclerotic vascular disease. Particulate embolization, which is usually cotton fiber, is present in as many as 25% of resected arteriovenous malformations: the risk of finding such emboli is in part dependent on a history of prior interventional (as opposed to diagnostic) angiographic procedures. It is not surprising that the amount of tissue examined also increases the risk of finding such emboli. CONCLUSIONS: Unintentional foreign body emboli remain common in modern angiographic practice and are probably underappreciated clinically. Although such emboli are usually asymptomatic, they can be clinically devastating, and a high index of suspicion is required for diagnosis. Foreign body emboli should be included in the differential diagnosis of postangiographic ischemia or infarction.- - - - - - - - - - ranking = 0.25keywords = vascular disease (Clic here for more details about this article) |
7/22. Multiple cerebral and pulmonary arteriovenous malformations in association with brain and subcutaneous abscesses: a possible variant of hereditary hemorrhagic telangiectasia--case report.The authors present a case in which multiple cerebral and pulmonary arteriovenous malformations (AVMs), a brain abscess, and a recurrent subcutaneous abscess were found concurrently in a 52-year-old male. He was admitted to our hospital for evaluation of a subcutaneous abscess in the right nuchal area and a right occipital AVM that had been detected at another hospital. Of his eight siblings, three had died of cerebrovascular disease (one in childhood and two as young adults), one had died of unknown causes in childhood, one had been hemiplegic since infancy, one had recently undergone removal of a pulmonary AVM, one was killed in world war ii at the age of 24 years, and the remaining sibling was healthy. He had had surgery for a right occipital brain abscess three years prior to this admission. A general examination revealed no abnormalities other than the painful right nuchal mass. Neurological evaluation disclosed left homonymous hemianopsia, which was probably a result of his previous surgery for the right occipital brain abscess. cerebral angiography showed AVMs in the right parietal (2 x 2 cm), right occipital (1.5 x 1.5 cm), and right cerebellar areas (1 x 1 cm). Digital subtraction angiography of the lung revealed multiple bilateral AVMs. The cerebral and pulmonary AVMs were removed in a two-stage operation. Although this case did not correspond precisely to the triad of hereditary hemorrhagic telangiectasia (HHT), the authors consider it to be related to HHT, since that syndrome is often complicated by multiple cerebral and pulmonary AVMs.- - - - - - - - - - ranking = 0.25keywords = vascular disease (Clic here for more details about this article) |
8/22. Focal headache during balloon inflation in the internal carotid and middle cerebral arteries.Although a number of reports are available on the occurrence of headache in patients with ischemic cerebrovascular disease, most studies have recorded the frequency but not the specific sites of the pain. We report 18 patients who underwent balloon inflation in the distal internal carotid artery and middle cerebral artery stem during embolization therapy for intracerebral arteriovenous malformations. Eleven patients had reproducible patterns of headache during balloon inflation. Inflation in the proximal middle cerebral artery stem produced pain primarily in the ipsilateral temple, that in the middle of the middle cerebral artery stem produced pain referred primarily retro-orbitally, and inflation in the distal middle cerebral artery stem produced pain referred primarily to the forehead. Experimental studies have demonstrated similar patterns of referred pain. The fact that these areas of referred pain are so reproducible is of potentially great clinical importance in the approach to management of patients with cerebrovascular disease.- - - - - - - - - - ranking = 0.5keywords = vascular disease (Clic here for more details about this article) |
9/22. An intracranial arteriovenous malformation and palatal myoclonus related to pseudoxanthoma elasticum.pseudoxanthoma elasticum is a rare hereditary disorder of elastic tissue with central nervous system manifestations due to occlusive vascular disease and aneurysm formation. Here we report the first recorded case of an intracranial arteriovenous malformation (AVM) in a patient with pseudoxanthoma elasticum. The AVM, which was located in the pons, also had an unusual manifestation, namely palatal myoclonus.- - - - - - - - - - ranking = 0.25keywords = vascular disease (Clic here for more details about this article) |
