A Case of Persistent Sciatic Artery Developing Spontaneous Occlusion without Ischemic Complications

抄録

We report a case of persistent sciatic artery which occluded spontaneously without lower limb ischemia. A 74–year–old woman presented with painless pulsation in her right buttock. She underwent computed tomographic angiography (CTA), which showed complete persistent sciatic artery. We decided on conservative management with 3–monthly CTA. After 12 months CTA showed that the persistent sciatic artery had developed spontaneous occlusion with thrombi. In conclusion, when there is little ischemia and risk of rupture, conservative treatment can be appropriate. CTA is a very useful imaging modality in the follow–up of persistent sciatic artery.
