Article Abstract
All current endovascular aneurysm repair (EVAR) devices have defined limitations that prevent the endovascular therapist from using them to treat all forms of aortoiliac aneurysm disease. Short, angulated infrarenal aortic neck pathology, occlusive disease in iliac access arteries, need for preservation of important branch vessel arterial flow, endograft migration, and endoleak all represent major impediments for successful EVAR. Need for secondary intervention after EVAR in a significant number of patients has detracted from universal acceptance for this therapy. New devices in manufacturers' pipelines may provide solutions for many of the current EVAR device deficiencies. As these new devices become more complex, meticulous patient follow-up to verify anticipated outcomes and new training paradigms for the future endovascular therapist will be required.

Tips and Tricks to Facilitate Late Open Surgical Conversion after Endovascular Aortic Aneurysms Repair.

Endovascular repair has significantly improved the treatment of aortic aneurysms, particularly in older and high-risk patients. However, many studies have not found significant differences in long-term outcomes when comparing open and endovascular repair methods. Additionally, endovascular repair is associated with a higher rate of aortic-related reinterventions compared to open repair (OR), sometimes necessitating late open surgical conversion (LOSC).

Objectives: Trauma poses a significant health burden in Saudi Arabia, with high rates of morbidity and mortality rates. We evaluated the trends among trauma team (TT) physicians in Saudi Arabia regarding their awareness and referral practices for percutaneous endovascular arterial embolization (EAE) in bleeding patients.
Methods: A 13-question survey developed by consultants from various specialties assessed the knowledge of TT physicians regarding decision-making and appropriate approaches for managing traumatic bleeding.
Iliac branch endoprosthesis for endovascular treatment of complex aorto-iliac aneurysms - from device design to practical experience: how to translate physiology considerations into clinical applications.

Article Synopsis
- - This article reviews current literature and expert opinions on using iliac branch endoprosthesis (IBE) for treating complex abdominal aortic aneurysms (AAA) that also involve the iliac arteries.
- - Around 25% of AAA patients have aneurysms that extend into ilac vessels, complicating standard endovascular aortic repair (EVAR) procedures and requiring careful assessment to ensure proper treatment.
- - The IBE is shown to be an effective and durable treatment option for complex aorto-iliac aneurysms, offering results comparable to open surgery but with lower risks, while also preserving pelvic circulation to avoid potential complications.
Transatlantic Delphi Consensus on the Common Iliac Artery Sealing Zone in Endovascular Aorto-Iliac Aneurysm Repair (the DECIDE Study).

Division of Vascular Surgery, Department of Surgery, University Medical Center Groningen, Groningen, The Netherlands.
Objective: Knowledge of hostile factors and their influence on long-term seal in the iliac landing zone is limited. Currently endorsed clinical practice guidelines lack structural evidence on how the iliac landing zone should be assessed in the pre-, intra-, and postoperative phases. The goal of this study was to obtain an international, expert-based consensus on the definition of a hostile iliac landing zone, on how to size and plan stent-grafts to optimize sustainable distal seal, and on the postprocedural follow-up protocol.

Abdominal Aortic Aneurysm (AAA) represents a signif i cant global health issue with a high risk of rupture, resulting in substantial mortality rates. Endovascular Aneurysm Repair (EVAR) has emerged as the preferred treatment method due to its minimally invasive nature. However, the procedure carries a risk of acute kidney injury (AKI), particularly post-contrast acute kidney injury (PC-AKI), which can adversely af f ect patient outcomes.
