Summary: In this study comparing aortoduodenal fistulas (ADFs) after endovascular abdominal aortic aneurysm repair (EVAR) vs after open aortic repair (OAR), it was found that patients in the OAR group had significantly higher postoperative complication rates compared to the EVAR group. The most common bacteria identified in blood cultures were Escherichia coli, with Candida spp. being the predominant pathogen found on intra-abdominal smears.

Summary: This study compared the results of two commercially available devices for branched thoracic endovascular aortic repair and fenestrated thoracic endovascular aortic repair. The results showed that both methods had excellent technical success and acceptable complication rates, but branched repair tended to have higher stroke rates. Meanwhile, fenestrated repair had a wider range of applicability.

Summary: Common iliac artery aneurysm complicated by ilio-iliac arteriovenous fistulas is a rare but fatal condition that requires prompt treatment. Endovascular therapy is appropriate for reducing morbidity and mortality in such cases. Successful repair of the fistula can be achieved by stenting the common iliac vein with an aortic extension cuff.

Summary: Aorto-duodenal fistula (ADF) is a rare cause of upper gastrointestinal bleeding, usually occurring in patients with prior aortic surgery or aortic graft placement. Due to difficulties in diagnosis, the surgical correction of ADF has a poor outcome.

Summary: This study aimed to assess the practicability and safety of a novel endovascular robotic system for endovascular aortic repair in humans. A prospective observational study was conducted in 2021 with 6 months of follow-up. The results showed that the robotic system achieved technical success in all patients without any device- or procedure-related complications or major adverse events. The operation time, blood loss, and radiation exposure of the operator were comparable to manual procedures.

Summary: This article presents a deeply implanted stent antenna system for endovascular aneurysm repair (EVAR) with better antenna characteristics. The proposed stent antenna exhibits wide-band characteristics and high gain, with perfect impedance matching. Simulations and measurements validate the attributes of the stent antenna, and a link budget analysis is performed.

Summary: Early endovascular intervention improves the maturation rate and interval of native arteriovenous fistula (AVF). Ongoing endovascular reinterventions after maturation result in a low reintervention rate and long-term patency, providing reliable long-term renal vascular access.

Summary: This study reviewed the clinical experience of using an EVAR-only strategy for the management of ruptured abdominal aortic aneurysms (RAAAs) and discussed its feasibility. The results showed that the EVAR-only strategy allowed rEVAR to be used in almost all RAAAs with similar mortality compared to the EVAR-selected strategy. The EVAR-only strategy was associated with a simplified algorithm, less impact on hemodynamics, and shorter operation and recovery time.

Summary: This study evaluates the technical outcome of fenestrated endovascular aortic repair (FEVAR) after prior EVAR and identifies factors that may influence complication rates. The results show that the technical failure rate significantly decreases in FEVAR after EVAR patients, and the occurrence of primary unconnected fenestrations is similar to primary FEVAR. However, the operating time is longer. FEVAR can be a feasible and safe treatment option for patients with progression of aortic disease or type Ia endoleak after EVAR.

Summary: Through analyzing the reports related to thoracic endovascular aortic repair (TEVAR) in the FDA's Manufacturer and User Facility Device Experience (MAUDE) database, it was found that there is an association between the Medtronic Valiant device and type IIIb endoleaks, and this association can be traced back to 2013. The study also discovered that all type IIIb endoleaks occurred in patients who received TEVAR with devices containing sutured on woven fabric.

Summary: The study used pressure gradient measurements to evaluate renal artery flow hemodynamics after chimney endovascular aortic repair (chEVAR). The results showed that the technique is safe and allows direct measurement of renal artery flow dynamics, with no significant changes in pressure values post-procedure. Additionally, the use of covered balloon expandable stents ensured proper blood flow in the renal arteries during the chEVAR technique.

Summary: Abdominal aortic aneurysm (AAA) is a condition where the abdominal aorta dilates and grows until it ruptures. EVAR is a minimally invasive procedure using stent grafts to treat this condition. Recent advancements have introduced polymer-based technology as a safe and effective alternative to seal AAA.

Summary: This study aims to evaluate the mid-term outcomes of fenestrated endovascular aneurysm repair (FEVAR) for proximal aortic pathology after previous open surgical repair (OSR). The study found that FEVAR is a safe and effective alternative for the endovascular treatment of para-anastomotic aneurysms/pseudoaneurysms after OSR, with high technical success, low mortality and morbidity, and good mid-term outcomes.
