Introduction: The Pipeline embolization device (PED) is a relatively new device used to treat complex aneurysms. The optimal method of radiographic follow up for patients treated with the PED has not been established. The rate of in-stent stenosis is unknown.
We evaluate the use of trans cranial doppler ultrasound (TCD) for detecting in-stent stenosis.
Methods: We analyzed 28 patients treated with the PED over the course of 42 months from January 2009 to June 2012. A standard conventional cerebral angiogram was preformed in all patients. TCD studies were available in 22 patients.
Results: Angiographic and US results were compared and found to be highly correlative (P<0.001)
Conclusions: TCD is a potentially useful adjunct for evaluating in-stent stenosis of the PED.
Patient Care: By decreasing the need for repeat cerebral angiography in patients with the pipeline embolization device.
Learning Objectives: The learner will be able to describe the potential role of doppler ultrasound as it applies to long term follow up of the the Pipeline Embolization Device.
