[Sensitivity of preoperative diagnosis in mesenteric vascular occlusion].

In a consecutive series the sensitivity of the preoperative diagnostic in acute mesenteric vascular occlusion was investigated prosprectively in 62 patients. 22 patients had an arterial thrombosis, 20 patients a venous thrombosis, 13 patients had an embolism, six patients a non-occlusive disease and one patient suffered from a dissection of the aorta. All but three patients (95.2%) had a leukocytosis with an average of 18,700/nl. The serum lactate was increased in 88.7% of the patients. The percutaneous ultrasonography was without any pathological findings in 45% of the patients. The x-ray of the abdomen shows signs of an ileus in more than half of the patients. The angiography had a sensitivity of 74%.
