AI Article Synopsis
- The study evaluated the clinical success and efficacy of the E-liac Stent Graft System after 12 months, defining success as aneurysm exclusion and proper blood flow in the iliac arteries.
- The research involved 45 patients across 11 European centers, with a significant majority being male and an average age of 72 years, focusing on both aorto-iliac and isolated iliac treatments.
- Results indicated a 90% overall clinical success rate, a 100% survival rate, and high primary patency rates of 98% for both the internal and external iliac arteries, highlighting the device's safety and effectiveness, with further long-term data pending.
Article Abstract
Objectives: At 12 months follow up of the PLIANT study, clinical success and efficacy of the E-liac Stent Graft System (JOTEC GmbH, Hechingen, Germany) were evaluated. Clinical success was defined as aneurysm exclusion (no type I, III, IV endoleak) with primary patency of the internal iliac artery (IIA) and external iliac artery (EIA) on the E-liac implantation side.
Methods: In this prospective multicentre European observational study, clinical and morphological data of 45 patients (93% male, mean age 72 y) were prospectively collected in 11 European centres between July 2014 and June 2016. Forty patients underwent an aorto-iliac (three patients bilaterally) treatment and five an isolated iliac treatment.
Results: At 12 months follow up, data were available for 42 patients. Overall clinical success at 12 months was 90%, with a survival rate of 100%. Four patients (10%) did not achieve clinical success, one with an internal iliac artery (IIA) occlusion on the E-liac implantation side, one with an infrarenal type Ia endoleak, and two with type Ib endoleaks in IIA. At 12 months the primary patency rate in the internal iliac artery on the iliac side branch implantation side was 98%. Two patients (5%) received E-liac related re-interventions: one caused by an edge stenosis at the distal end of the graft limb in the external iliac artery (EIA) and one caused by thrombo-embolism in the external iliac artery. Thus, for the EIA, primary and secondary patency rates were 98% and 100%, respectively.
Conclusions: The low device related re-intervention rate of 5%, the high survival rate of 100%, and the high primary patency rates of 98% for the IIA and EIA at 12 month follow up demonstrate the safety and efficacy of the E-liac Stent Graft System. Long term 36 month results are awaited to confirm the efficacy and durability.

This study aimed to evaluate the efficacy of the single-energy metal artifact reduction (SEMAR) algorithm in reducing metal artifacts and enhancing image quality in contrast-enhanced computed tomography (CT) for patients undergoing endovascular aneurysm repair (EVAR) with coil embolization. Thirty-eight patients (mean age 81.0 ± 6 years; 31 men, 7 women) who underwent contrast-enhanced CT following EVAR and internal iliac artery coil embolization between September 2022 and May 2023 were retrospectively analyzed.

Background: No appropriate studies have been conducted that compare the biomechanical properties of different fenestration positions in deep circumflex iliac artery (DCIA)-vascularized iliac bone grafts for femoral head necrosis (ONFH) treatment. In this study, we aimed to explore the fenestration locations of DCIA-vascularized iliac grafting in ONFH treatment using FEA and clinical retrospective analysis.
Methods: We simulated an iliac bone flap transplantation with a vascularized tip by finite element analysis (FEA).

Introduction: Compared to aortic dissection and isolated visceral artery dissection, multiple peripheral arterial dissections have not been formally reported to date. Currently, there is no well-established treatment for this condition, and large-scale studies with extensive sample data are lacking.
Case Presentation: A 56-year-old male, was provisionally diagnosed with " idiopathic multiple peripheral arterial dissections.

Introduction: Vascular injury during acetabular screw fixation is a life-threatening complication of total hip arthroplasty. This study uses three-dimensional computed tomography to (1) measure absolute distance from the external iliac artery (EIA) to the acetabulum, (2) determine available bone stock along the EIA path, and (3) create a novel acetabular vascular risk map.
Methods: A retrospective radiographic study was conducted using three-dimensional CT.
