Duckworth, e.A.Et al.(2015).Separating the wheat from the chaff: region of interest combined with metal artifact reduction for completion angiography following cerebral aneurysm treatment.Journal of neurointerventional surgery, 8(11), 1163-1167.(b)(4).The pipeline devices will not be returned for evaluation as they remain implanted in the patients.Based on the information provided in the article, there did not appear to have been any defect of the device during use.The reason for retreatment could not be determined from the information provided in the article.

Medtronic literature review found a report of retreatment after pipeline implantation.The purpose of the article was to investigate the investigate different methods of two- and three-dimensional angiography to evaluate the correct positioning of implantable devices while limiting radiation dose to the patient.The authors reviewed 9 patients who underwent 10 procedures; 5 of the patients underwent pipeline implantation to treat cerebral aneurysms.Of the 9 patients, 1 patient had a ruptured aneurysm, 8 aneurysms were in the anterior circulation.Average aneurysm size was 11mm.The article states that two patients treated with the pipeline device were retreated with a second device.
