Internal capsule avoidance and angiography in hypertensive intracerebral hemorrhage

Abstract

According to the cerebrovascular images, it is deduced that the cerebral hemorrhage is limited to the putamen and does not affect the internal capsule and its hind limbs. The author calls it the internal capsule avoidance phenomenon of cerebral hemorrhage. With regard to the mechanism of internal capsule avoidance, it is generally believed that the lenticulostriate artery, especially the bifurcation of its lateral branches, is necrotic or the true small aneurysm ruptures. As for how bleeding develops into a large hematoma, there are currently different opinions. Through the observation of ultra-soft X-rays, the author believes that the rupture of the lateral branch of the lenticulostriate artery causes bleeding and leads to
