Stroke. Coloured angiogram of the brain of a 48 year old patient after a massive cerebrovascular accident (CVA),or stroke. There are fewer blood vessels visible compared to normal (see image M136/0347). This is due to a blocked middle cerebral artery causing areas of ischaemia (lack of blood flow) to parts of the brain. The blockage may be due to a thrombus (blood clot) or embolism (air bubble or loose blood clot). Strokes can be instantly fatal,or may pass unnoticed. Symptoms can include muscle weakness,behavioural changes or paralysis. Angiograms use a contrast dye to highlight blood vessels | |
