[Specular bilateral lenticular hematomas].

A 49-year-old right-handed hypertensive female developed two consecutive putaminal hemorrhages in the left and right hemispheres within one month. Recurrent specular hypertensive hematomas are rare, even though the underlying pathological changes in the arterial wall occur bilaterally. This may be explained by the spontaneous decrease in blood pressure occurring in patients after an acute stroke. In this patient, a new abrupt increase in blood pressure may account for the second hemorrhage. While lowering the blood pressure during an acute stroke may be in principle unadvisable, it seems reasonable to prevent a new increase in blood pressure with adequate therapy.

Impedance rheography: a new method for recording spontaneous arterial section variation.

The aim of this work is to define, on the basis of impedance rheography, a method to record arterial section variations without either inertia or the production of wall-strain. High frequency current (2 MHz) is employed to measure the impedance variations of the deforming artery. The modulating envelope is representative of arterial section variations. This method permits the recording of arterial section variations by a peri-arterial method or an external method on superficial arteries (without denudation). A comparison between arterial section variations and arterial pressure variations at the same point shows that the arterial wall behaves as a non-linear pressure gauge: Rheogram-pressure curves are similar to volume-arterial pressure curves. The great precision with which this method describes the chronology of arterial deformations is of great interest in defining viscous properties of the arterial wall and following their evolution during pathologic alterations such as atherosclerosis.
