Inadvertent embolization of a persistent sciatic artery in pelvis trauma.
We describe a case of unilateral persistent sciatic artery (PSA), a rare vascular anomaly, in a 43-year-old woman with severe multiple trauma. A small amount of diluted embolization particles went into this vessel during emergent endovascular therapy under fluoroscopic monitoring. The procedure was immediately stopped when the true nature of the anatomic variant was recognized. Fortunately, an ischemic event of the lower leg did not occur. The imaging findings of computed tomography and digital subtraction angiography are presented and the relevant literature is reviewed.
