Abstract

Introduction: Hourglass-shaped abdominal aortic aneurysms (AAAs) represent a complex variant of aneurysms, characterized by a distinctive constriction within the aorta, which are characteristically located in the abdominal or thoracic regions. Their unique morphology poses significant diagnostic and therapeutic challenges, particularly when considering the feasibility of endovascular repair versus open surgical intervention, demanding a specific approach to management. Case presentation: We present the case of a 68-year-old female patient admitted with abdominal pain complaints. Despite stable vital signs, her medical history, including diabetes mellitus and reduced ejection fraction (EF) of 40 %, indicated a heightened cardiovascular risk. Subsequent imaging studies, including Doppler ultrasonography and CT angiography, showed the presence of two adjacent abdominal aortic aneurysms forming an hourglass-shaped configuration. Due to the inadequacy of the proximal landing zone for an endovascular procedure, an open surgical intervention was considered necessary to address the aneurysms. Discussion: Managing the hourglass-shaped AAAs requires careful consideration due to their complex morphology, which can complicate the option between endovascular and open surgical repair. While Endovascular Aneurysm Repair (EVAR) is often a preferred method for high-risk patients due to its minimally invasive nature, in this case, insufficient proximal landing zones made the EVAR unsuitable. Open surgery, although more aggressive, was required to prevent complications such as ensuring a safe repair and rupture. Perspective imaging and patient-specific factors played an important role in guiding the treatment plan, highlighting the importance of individual approaches in managing complex vascular discrepancies. Conclusion: The present article reports the management of a patient with an hourglass-shaped AAA, emphasizing its relevant diagnostic challenges, the rationale behind treatment decisions, and the outcomes we achieved. Our findings highlight the need for personalized approaches in managing complex aneurysmal presentations. © 2025
