Multiple Pipeline Twists Encountered During Treatment Of A Symptomatic Fusiform Ica Aneurysm
BMJ CASE REPORTS(2019)
摘要
Pipeline embolisation device (PED) 'twisting' is an intra-operative complication that manifests with the appearance of a 'figure-8' in perpendicular planes on digital subtraction angiography. A twisted PED causes narrowing and/or complete occlusion of the vessel lumen and poses significant risks for thrombus formation and downstream ischaemia. Here, we present a case in which three unique PED implants become twisted during pipeline embolisation of a large fusiform internal carotid artery aneurysm. The twists were remediated by balloon angioplasty and a combination of techniques that allowed the PED to rotate and restore its original axis. Six-month and twelve-month follow-up angiography demonstrated complete aneurysm occlusion with preservation of the parent vessel, proving that proper remediation of PED twisting can still result in successful long-term outcomes.
