Observations concerning intracerebral vascular occlusions

Anatomy and Functionality of Leptomeningeal Anastomoses

“…Zatz et al 95 (1965) was convinced that as a result of LMA, there is a possibility of major cerebral artery occlusion without consequent neurological deficit.…”

Transient embolic occlusion of the middle cerebral and internal carotid arteries in cerebral apoplexy.

“…In Riishede's (1957) cases the death rate in patients with MCA occlusion was seven out of 10, while in our case this was 10 out of 25. shown in the acute phase may recanalize in a later stage of the illness. In fact, previous publications report some cases where the angiographic or necropsy check-up effected a few weeks later shows the disappearance of the occlusion of a MCA observed in the acute phase (Ecker, 1945, one case;Lehrer, 1958, one case;Jacobsen and Skinh0j, 1959, two cases;Gannon and Chait, 1962, one case;Meyer, Gilroy, Barnhart, and Johnson, 1963, two cases;Dalal, Shah, and Aiyar, 1965, eight cases;Zatz, lannone, Eckman, and Hecker, 1965, four cases). We are now adding seven cases in which a MCA occlusion diagnosed in the first or second day after the stroke had disappeared at the time of a later examination.…”

Cerebral Emboli Complicating Cerebral Angiography

“…Small arterial occlusions are difficult to identify at post mortem examination even when accompanied by infarction. Spontaneous lysis, which may occur within hours to days of an occlusion, may partially explain this difficulty (20).…”
