Abstract
Symptomatic dilation of a spontaneous splenic artery dissection is a very rare and potentially catastrophic nonatherosclerotic vascular disease. Splenic artery rupture has not been reported after acute diffuse dilation, but it has been reported with celiac artery dissections. We believe treatment is mandatory if pain persists despite blood pressure control. The presentation and endovascular treatment of a spontaneous celiac trunk dissection with continued expansion of the splenic artery branch are discussed.
