= reduced blood flow through a Organ District, as a result of reduced blood supply.
causes
| local causes | General causes |
| narrowing or complete blockage of an artery
| hypovolemia |
consequences: depend on:
(a) duration [3 - 5 min. ischemia has no harmful effect min> 5. are to follow recorded according to fabric]
(b) primary sensitivity of the tissue [specialized cells or organ tissues holds 1 - from 1.5 hours ischemia, skin tissue for several hours]
(c) vascular architecture [is possible, a collateral circulation ?; dual blood supply is available;? are functional end arteries exist]
infarction localized necrosis of a body part ...? verurscht ligated by blood flow.
-
ischemic infarction -
blaser infarction -
by arterial occlusion (coagulation necrosis) -
hemorrhagic infarction -
red infarct -
