Reliability of Hospital-Level Mortality in Abdominal Aortic Aneurysm Repair
The relationship between volume and surgical outcome has been shown for a variety of surgical procedures. The effect in abdominal aortic aneurysm repair continues to be debated. Reliability adjustment has been used as a method to remove statistical noise from hospital level outcomes but its impact on aortic aneurysm repair is not well understood.
The introduction of endovascular abdominal aortic aneurysm repair (EVAR) led to a reduction in open repair (OAR) cases, raising concerns regarding patient safety and future training of vascular surgeons. Our objective is to analyze trends in OAR and EVAR cases and their implications on vascular surgery training.
Surveillance imaging receipt post-abdominal aortic aneurysm (AAA) repair is generally poor and declines over time. Here we evaluate rates of guideline-complaint imaging following AAA repairs in the Veterans Administration (VA) system which may have fewer barriers to accessing care.
Despite improvements in screening, diagnostics, as well as repair methods for abdominal aortic aneurysms (AAA), disparities continue to prevail in non-white vs white patients. We aim to describe differences in surgical outcomes between ethnic groups undergoing repair for non-ruptured AAA.
The effect of body mass index (BMI) on vascular surgery has been studied, but relative risks in repair of abdominal aortic aneurysms (AAA) is underreported. We studied the “obesity paradox” in patients undergoing open vs. endovascular AAA repair to determine risk associated with BMI in this high-risk cohort.
This study aims to assess the content and quality of current videos of endovascular aneurysm repair (EVAR) of abdominal aortic aneurysm (AAA) on YouTube.
While efforts such as the Screening Abdominal Aortic Aneurysms Very Efficiently (SAAAVE) Act have improved access to abdominal aortic aneurysm (AAA) screening, certain high-risk populations are currently excluded from the guidelines yet may benefit from screening. We therefore examined all patients who underwent repair of ruptured AAA (rAAA) to characterize those who are ineligible for screening under current guidelines and evaluate the potential impact of these restrictions on their disease.
CONCLUSIONS: This study suggests that EVAR cannot improve survival outcomes compared with OSR if applied solely because a patient is aged ≥80 years. Not only age but also other risk factors and quality of life after surgery need to be further studied.PMID:34670876 | DOI:10.1253/circj.CJ-21-0574
: thoraco-abdominal endovascular aortic repair (TA-EVAR) can be associated with platelet depletion (PD); the present study aims to evaluate PD incidence after TA-EVAR and to investigate its possible predictors and its influence on hemorrhagic complications and mortality.
CONCLUSIONS: Combined AAA repair and aorto-femoral bypass has a significantly higher 30-day mortality and postoperative complication rate than isolated AAA repair. Patients with concomitant AAA and AIOD thus represent a high-risk population, which should be considered when deciding on the indication for AAA treatment.PMID:34668688 | DOI:10.4414/smw.2021.w30050

Online ahead of print.ABSTRACTAbdominal aortic aneurysm is a process involving the disruption and reconstruction of the extracellular matrix and the apoptosis of smooth muscle cells under the strong influence of the immune system. Thrombospondins are proteins that influence a wide range of cell-matrix interactions. While THBS1 and THBS2 are widely studied, the effects of THBS3 on extracellular matrix and vascular cells are poorly understood. Additionally, it is not known whether expression of these genes' changes along the aneurysm tissue. Here we analyzed the exp...
