Summary: This study compared the outcomes of bTEVAR and hTEVAR in landing zone 0 for the treatment of aortic arch diseases. The study found no significant differences in in-hospital mortality, aorta-related deaths, and aortic reintervention rates between the bTEVAR and hTEVAR groups. However, the bTEVAR group had significantly shorter operative time and length of hospital stay compared to the hTEVAR group.

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: This study reports the early and late outcomes of endovascular repair of complicated infrarenal abdominal penetrating aortic ulcer (PAU) using aortobi-iliac endograft and embolization. The results show that this approach is safe and effective, with excellent technical results and satisfactory midterm clinical outcomes.

Summary: Thoracic endovascular aortic repair (TEVAR) is a commonly performed operation for patients with type B aortic dissection (TBAD) to reduce the risk of aortic aneurysm and rupture. However, it can lead to complications and has controversial treatment methods. This study used computational fluid dynamics (CFD) to investigate the relationship between the length of the endograft used in TEVAR and hemodynamic variables, and found that a medium-length endograft may be optimal for achieving FL flow reversal and minimizing the extra load on the left ventricle.

Summary: Most male X-linked Alport syndrome patients with COL4A5 nonsense mutations develop end-stage kidney failure by the age of 30. High-flow arteriovenous fistula, defined by access blood flows greater than 2000 mL/min, may lead to high-output heart failure. This case report describes a 50-year-old Japanese man who had proteinuria at the age of 4, followed by lenticular lens and sensorineural hearing loss at 20, and eventually started hemodialysis treatment for end-stage kidney disease at 22.

Summary: TEVAR is the most effective treatment for aortic diseases, and this study evaluates the biomechanical implications of the implanted endograft after surgery. Using a novel computational framework, the study found that endograft implantation weakens the aorta's buffer function and reduces mean energy loss by 19.1%. The interaction between blood flow, endograft, and aortic wall is crucial for physiologically accurate hemodynamics post-TEVAR. The deformation of the aortic wall is responsible for the major energy loss in blood flow.

Summary: This study aimed to clarify the clinical features, postoperative outcomes, and prognostic factors in patients with endograft infection in the abdominal aorta and iliac artery. Surgical intervention for endograft infection in the abdominal aorta and iliac artery was associated with a high risk of postoperative morbidity and mortality, and partial removal or total preservation of the infected endograft can lead to a poor prognosis.

Summary: This study developed high-fidelity Finite Element simulations for modeling thoracic stent-grafts and proposed a new methodology for simulating device insertion and deployment. The reliability and applicability of the proposed method were verified and demonstrated through experimental validation and comparative analysis.

Summary: This study reports the closure of iliac arteriovenous fistulas associated with a post-thrombotic iliac vein occlusion by iliac venous stent recanalization. The findings suggest that primary venous stent recanalization should be considered when dealing with post-thrombotic venous obstructions with arteriovenous fistulas related to aforementioned venous lesions.

Summary: The study aimed to evaluate the clinical and technical results of using a novel physician-modified endograft (PMEG) with hydrogel-reinforced fenestrations for complex thoraco-abdominal aortic pathologies. Successful reconstruction of all branches was achieved using the hydrogel-reinforced fenestrations, with low postoperative complications and high survival rate.

Summary: Spinal dural arteriovenous fistula (SDAVF) is the most common vascular malformation of the spine, but can be difficult to diagnose due to subtle magnetic resonance imaging signs. In this case study, we present a patient with SDAVF and syringomyelia of the thoracic spinal cord, and hypothesize that the fistula may cause intramedullary fluid accumulation leading to syrinx formation.

Summary: The study demonstrated that utilizing a small-diameter prosthetic graft as a flow-limiting procedure for managing high-flow arteriovenous fistula can effectively relieve clinical symptoms, preserve the autologous behavior of the initial access, and offer a simple, effective, and durable treatment option.

Summary: Our study suggests that disturbed flow in dysfunctional arteriovenous fistulae (AVF) contributes to the development of neointimal hyperplasia (NH) through the induction of endothelial mesenchymal transition (EndMT) via the osteopontin/CD44 axis. We provided evidence from both animal and cell culture experiments to support this hypothesis. We also found that the osteopontin/CD44 axis is involved in AVF dysfunction in patients with uremia. These findings highlight the potential of targeting the osteopontin/CD44 axis as a therapeutic strategy for preventing AVF dysfunction.
