The device was not returned as it was implanted in the patient.The purpose of this article was to report the outcome of patients with cerebral aneurysms that incorporated an end vessel at the aneurysm neck or dome, which were treated by flow diversion using the pipeline embolization device.All patients either had post treatment dynact showing good wall apposition or had pta, and therefore it is unlikely that a persistent flow between the device and parent vessel was a contributing factor to the patency of the artery.There was also consistent antiplatelet regimen on the patients including clopidogrel for 6 months and aspirin dose reduction to 81 mg at 6 months.As a result, persistent patency was not likely to be related to dual antiplatelet therapy.The authors conclude that the use of flow diversion for treatment of aneurysms incorporating an end vessel is not recommended as it appears ineffective for complete aneurysm occlusion.In this case, the patient did require retreatment via surgical clipping.Based on the information discussed in the article, the reported events are not related to a malfunction of the pipeline device, but rather related to the patient conditions and subset of cerebral aneurysm that was treated.Citation: akil patel,timothy r miller, ravi shivashankar, gaurav jindal, dheeraj gandhi.Early angiographic signs of acute thrombus formation following cerebral aneurysm treatment with the pipeline embolization device.J neurointervent surg 2016.Mdrs from this literature review: 2029214-2017-00206 and 2029214-2017-00207.A good faith effort will be made to obtain the applicable information relevant to the report.If information is provided in the future, a supplemental report will be issued.
