[Radiological features of non-gangrenous ischaemic colitis (author's transl)].

The authors have performed barium enema in 22 cases of non gangrenous ischaemic colitis. The diagnosis was established on the clinical, endoscopic and radiological data. The barium enema's radiological features and their evolution are described in particular thumbprinting, ulcerations, stenosis and sacculations. All these radiological signs were confirmed by endoscopic investigation or pathological examination. Abdominal angiography are carried out in 10 cases. The preferential site of the lesions is the descending colon. The differential diagnosis with other colitis are discussed and the diagnosis is easier when the barium enema is performed soon.
