Article Abstract
Traumatic intracranial pseudoaneurysm (PSA) is a rare yet dangerous subtype of cerebral aneurysm. The pipeline flex embolization device (PED Flex) has recently been applied to treat intracranial PSA. Herein, the authors report a middle-aged patient with intracranial subarachnoid hemorrhage and intracerebral hematoma after blunt cephalic trauma. The trauma led to PSA in the A2 segment of the left anterior cerebral artery (ACA). The patient was treated with simple coil embolization to prevent rebleeding in the acute phase. After 20 days, angiography revealed recurrence of the aneurysm. Thus, PED Flex was implanted in the second phase. A 6-month postoperative follow-up revealed the complete disappearance of posttraumatic PSA, and the ACA remained unobstructed. This study shows good technical results in applying PED Flex in cases of posttraumatic ACA PSA with clinical improvement.

Background: The Pipeline Flex embolization device with Shield technology (PED Shield, Medtronic, Irvine, CA, USA) is a flow diverter designed to reduce thrombogenicity through phosphorylcholine surface modification. Although in vitro and in vivo studies have demonstrated the thrombogenicity reducing effects of this technology, its effectiveness in real-world clinical practice remains unclear. This study aims to compare the number of post-procedure diffusion-weighted imaging (DWI)-positive lesions between PED Flex(Medtronic, Irvine, CA, USA) and PED Shield to assess the impact of surface modification.

Background And Objective: Flow diverters (FDs) are widely used in the treatment of intracranial aneurysms (IAs). The Lattice flow diverter (LFD) is a novel FD developed in China, specifically designed for large or giant IAs. Currently, few studies have compared various FDs in the treatment of these conditions.

Background And Purpose: Unruptured intracranial aneurysms (IA) are pathologic bulging of the arterial walls that could rupture and cause SAH. Recently, stents with modified surfaces have been used as treatment for IA. Thus, comparing efficacy and security of the Pipeline Flex Embolization Device with Shield Technology (PED-Shield) and the Pipeline Vantage Embolization Device with Shield Technology (PEDV) contributes to the scientific literature.

Article Synopsis
- The study examines the stability of the Pipeline Embolization Device (PED) in treating brain aneurysms, focusing on early generations and potential braid deformations.
- Data was gathered from the PREMIER trial, reviewing 133 out of 141 aneurysms for issues like braid bumping and foreshortening, assessing both safety and effectiveness.
- The results show that while a small percentage experienced braid deformations, they didn't significantly impact the device's safety or effectiveness over the follow-up period.
