Ultrasonography in traumatic splenic rupture.

Ultrasound (US) findings and their significance for the clinical outcome were studied in a series of 56 patients hospitalized with a diagnosis of splenic trauma. US was abnormal in 50 cases (89.3%) on admission, revealing intraperitoneal fluid in 41 (73.2%) and a splenic parenchymal injury and/or subcapsular haematoma in 35 (62.5%). US was abnormal in 24/25 patients undergoing urgent surgery, 23/26 undergoing successful non-surgical treatment and 2/5 patients undergoing delayed surgery within 1 to 3 days of a repeat US (abnormal in all five). The presence of intraperitoneal haemorrhage preoperatively was shown accurately by US in 29 cases (96.7%), and the splenic origin of the haemorrhage in 19 (63.3%). Repeat US was of most value for confirming the diagnosis by demonstrating splenic lesions not visible initially. The need for laparotomy could not be predicted on the basis of the US findings alone, however.
