Ultrasonic features of aneurysms of splanchnic arteries.

A review of nine patients with aneurysms of the splanchnic arteries was undertaken. The records and the sonographic findings were analysed. Seven of the nine aneurysms could be diagnosed ultrasonographically. The aneurysm appeared as a round hypoechogenic nodule connected to or in close relation with the feeding artery. In four patients the lesions were incidentally detected and two of them were operated upon because of a risk of spontaneous rupture.
