The etiology and the pathogenesis of the chronic @entity29 known as @entity30 and @entity31 have not been defined. Therefore, in this study the main emphasis was placed on description of the pathologic anatomy. Disturbed blood supply and @entity455 have been discussed as etiopathogenetic factors. The results in the literature are frequently contradictory. For this reason, the vascular system of the colon in @entity30 and @entity31 was systematically examined by means of various morphological methods in this study. Microvascular corrosion casting and translucent specimens were taken from operative specimens taken from 12 @entity1 with @entity30 and 8 with @entity31 . For comparison, @entity5 -free parts of 6 @entity694 specimens were examined. The evaluation was done by scanning electron- and/or stereoscopic microscopy. In the presence of chronic @entity29 , caliber differences in the tunica muscularis and rarefaction of the penetrating blood vessels were found. In summary, an @entity73 in the tunica muscularis can be postulated. For the first time, the resulting @entity2979 has been described, in contrast to the previously described disturbed arterial blood supply.
