3D-Printed Abdominal Aortic Aneurysm (AAA) Model for Hemodynamic Evaluation: A Pilot Study
Treatment of abdominal aortic aneurysms (AAAs) depends on the maximum diameter of the aneurysm. However, the pathophysiology and hemodynamics of AAA development and growth are still poorly understood. We aimed to develop a prototype of a patient-specific, AAA hemodynamic simulation model to find out patient-specific hemodynamic characteristics. (Source: Journal of Vascular Surgery)

Parallel Grafts to Treat Aorto-iliac Aneurysms: How to Size the Common Iliac Stent Graft
Aortoiliac aneurysms (AIA) occur unilaterally or bilaterally. Up to 40% of abdominal aortic aneurysms (AAAs) are associated with iliac artery aneurysms.[1] One technique to preserve internal iliac artery (IIA) blood flow is the sandwich technique (ST),[2] using two covered stents – one to the IIA, and the second to the external iliac artery (EIA) – which are placed inside the common iliac stent graft (the main limb of endovascular aneurysm repair; Fig 1.) It is very important to choose the correct sizing of common iliac stent grafts to decrease risk of type 3 endoleak.[3 ] (Source: Journal of Vascular Surgery)

Correlation Between Calcium Scoring and Abdominal Aortic Aneurysm Endovascular Repair Outcomes
Endovascular aneurysm repair (EVAR), though minimally invasive, is associated with many reinterventions and complications. Several variables have been studied to predict the outcomes of EVAR, one of which is the calcium burden of the vasculature. This prompted us to explore the correlation between the calcium burden of different aortic segments measured by the standardized Agatston scoring system, and the outcomes of EVAR.

Secondary Interventions After Custom-Made Iliac Branched Devices in Severe Iliac Tortuosity
Secondary interventions after implantation of an iliac branched device (IBD) in aortoiliac aneurysms occur in approximately 7.6 –10.2% of all cases. A pelvic tortuosity index (PTI) of>1.4 is associated with an even higher overall complication rate (hazard ratio [HR] 2.3) and re-intervention rate (HR 3.0). (Source: Journal of Vascular Surgery)

Segmental Arterial Mediolysis (SAM) Post Endovascular Aortic Repair: A Case Study and Brief Literature Review
Segmental arterial mediolysis (SAM) is a rare, non-inflammatory, non-atherosclerotic pathology that occurs commonly in the mesenteric vessels. There are no known predisposing risk factors to the development of SAM. (Source: Journal of Vascular Surgery)

Hypoechoic Perigraft Collection at Follow-Up After Aortic Bypass Surgery
Presence of a hypoechoic perigraft collection with size increase in a patient following aorto-biiliac bypass is uncommon, and is usually related to a periprosthetic seroma. Reported cases that are generally benign, infectious etiologies that can compromise the graft and increase the morbimortality for a patient must be excluded. (Source: Journal of Vascular Surgery)

Access-Related Outcomes for EVAR
Endovascular aortic repair (EVAR) is the first-line treatment for abdominal aortic aneurysms (AAA) in fit patients. Percutaneous vascular access (pEVAR) allows to decrease the invasiveness of EVAR in comparison to surgical femoral cutdown (sEVAR). The aim of this study was to compare the two access techniques and their impact on operative time, hospitalization, short- and long-term complications, and mortality.

Twenty-three Years of Experience in Aortic Endograft Explantation
Late open conversion (LOC) after failed endovascular aneurysm repair (EVAR) still represents one of the major challenges in the endovascular era. We aim to evaluate rates and indications, and peri- and long- term out-patient mortality of aortic endograft explantation. (Source: Journal of Vascular Surgery)

Comprehensive Aortic Training Course Using Cadaveric Pulsatile Flow Models to Improve Open and Endovascular Skills Throughout the Entire Spectrum of RAAA Management
The nationwide decline in the incidence of ruptured abdominal aortic aneurysm (RAAA) and open aortic aneurysm repair threatens with decreasing trainee experience across the US, which needs to be addressed. Due to the emergency nature of RAAAs, teaching is less emphasized during these cases. Consequently, it is imperative to provide a dedicated environment to educate trainees in a safe and stress-free manner. To improve the skillset and experience of vascular trainees in the management of RAAA we created a comprehensive RAAA training course which provides an opportunity to practice the entire spectrum of RAAA management in ...

AAA in Women: A Fast-track Protocol to Enhance Open Aortic Repair
Women experience higher mortality and complication rates than men after elective treatment of abdominal aortic aneurysms (AAAs). Moreover, the results disfavor the endovascular approach (EVAR) as compared to open surgical repair (OSR): women less often meet anatomic criteria for EVAR, making OSR a more appropriate, albeit burdensome option. We adopted a fast-track (FT) protocol, comprising 19 evidence-based recovery enhancing interventions, which allowed for a reduction of complication rates, shortened hospital stay, sped up the return of bowel function and mobilization, and improved pain control.

Aortic\Height Index as a Predictor of Symptomatic Status in Patients With AAA in a Southern Brazilian Population
The aim of this study was to compare the effectiveness of using the aortic/height index (AHI) compared to abdominal aortic aneurysm (AAA) diameter alone in risk-stratifying patients and predicting the likelihood of presentation with a symptomatic or ruptured aneurysm in a Southern Brazilian population. Additionally, we evaluated the AHI as a predictor of in-hospital mortality. (Source: Journal of Vascular Surgery)
