[Experimental skull and cerebral trauma and the early changes in the microangiogram in rabbits (author's transl)]

The second part of this investigation describes seven changes which have been observed in the post-traumatic microangiogram: defects, narrowing, rarefaction, incomplete filling, variations in callibre, "amputation" and bleeding. Reduction in the lumen is due to contraction of vessels in the microcirculation; this can be recognised histologically. Various causative factors are discussed. Bleeding and traumatic aneurysms are interpreted as being the result of direct trauma to the vessels.
