small bowel ischaemia

Dünndarmischämie
bei innerer Hernierung: Im linken Hemiabdomen zeigen sich aufgespannte, deutlich hypodense (minder- bis nicht mehr perfundierte) Dünndarmschlingen. Vergleiche normale Schlingen im rechten Hemiabdomen. Intraperativ zeigt sich partiell schon nekrotischer Dünndarm bei Einklemmung in einer inneren Hernie.

with abdominal pain. Coronal (above left) CT with contrast of the abdomen shows in the center just above the bladder a C-shaped dilated small bowel loop with a thickened wall that is not enhancing. On the sagittal image (above right) the dilated, thickened and nonenhancing small bowel loop is seen anteriorly in the abdomen and superior to the bladder. On the axial image (below) the small bowel loop is in the center of the pelvis.The diagnosis was Meckel diverticulum causing small bowel volvulus and a closed loop obstruction resulting in small bowel ischemia.

with abdominal pain who just had a cardiac arrest. AXR AP (above left) shows multiple dilated loops of small bowel and a decomopressed colon. Coronal CT with contrast of the abdomen (above right) shows normal caliber and normal enhancement of the proximal jejunum loops in the left upper quadrant. The distal ileum loops in the right lower quadrant are dilated and do not enhance. There is pneumatosis intestinalis in the walls of the most lateral loop of ileum. Axial CT (below) again shows the pneumatosis in the walls of the most lateral loop of ileum on the right and again shows the difference in bowel wall enhancement between the normal jejunum on the left and the abnormal ileum on the right.The diagnosis was Meckel diverticulum causing distal small obstruction due to small bowel volvulus around the Meckel diverticulum resulting in a closed loop obstruction and small bowel ischemia of the ileum and pneumatosis intestinalis from necrosis in the ileum.

Small bowel ischemia may be a life-threatening condition, arising from any one of numerous causes of disturbance of the normal blood flow through the small bowel wall.

Pathology

It can be divided into acute and chronic forms, with the main underlying etiologies (each discussed separately) being:
