1/2. Migraine associated bilateral intracerebral haemorrhages.The authors report a case of bilateral basal ganglionic haemorrhages which occurred during an attack of classical migraine. The patient had a history of migraine associated with aura of neurological deficit for 10 years and a history of arterial hypertension for 20 years, which was treated with propranolol. Intracerebral haemorrhage during an attack of migraine is very rare and up to now the existence of true migraine-induced intracerebral haemorrhage has been controversial. Our case of bilateral occurrence of the haemorrhages supports the theory of the existence of migraine-induced damage of the wall of intraparenchymal vessels during vasoconstriction and focal ischaemia at the beginning of a migraine attack. Subsequent vessel rupture may occur during the following period of increased cerebral blood flow especially with coexisting arterial hypertension. The terminology of the syndrome of migraine associated with intracerebral haemorrhage is reviewed.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/2. Hypotensive hemorrhagic necrosis in basal ganglia and brainstem.Hypotensive hemorrhagic necrosis of the basal ganglia and brainstem has only occasionally been described. Three such cases are reported. Cardiac arrest had occurred in all cases, and it took at least 1 hour to restore adequate circulation. The patients remained comatose for 2 days to 2 weeks until death. Persistent hypotension causing ischemia in the distribution of deep perforating arteries is considered to have been the key underlying mechanism. hemorrhage is thought to have been caused by extravasation of red blood cells through damaged blood vessels.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
