RESUMO
OBJECTIVES: A current and ongoing challenge is to reduce patient mortality after endovascular abdominal aortic repair (EVAR). This study aimed to assess the predictors of all-cause mortality after EVAR. METHODS: Data regarding the demographic characteristics, comorbidities, laboratory values, selected anatomical factors, post-EVAR treatment, surveillance and complications of patients who underwent elective EVAR for non-ruptured abdominal aortic aneurysm (AAA) between January 2010 and January 2021 were evaluated. Mortality was assessed until 10 October 2023. Multivariate analyses were performed after adjusting for age, hypertension, diabetes mellitus, dyslipidaemia, sex, smoking, number of lumbar arteries, patency of inferior mesenteric artery (IMA), IMA diameter and reinterventions. RESULTS: This study included 196 patients (183 men and 13 women) with a mean age of 72.4 ± 7.67 years. The overall mortality rate during a mean follow-up period of 5.75 ± 3.1 years was 50.0% (N = 98). The 2-, 5- and 10-year mortality rates were 9.7%, 32.0% and 66.6%, respectively. The mortality rates decreased by 59% in patients with reinterventions (hazard ratio [HR]: 0.41; 95% confidence interval [CI]: 0.23-0.73; p = .002) and by 59% in patients treated with angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs) (HR: 0.41; 95% CI: 0.26-0.66; p < .001). Chronic anticoagulation was associated with 2.09-fold higher mortality (HR: 2.09; 95% CI: 1.19-3.67; p = .010), and coronary artery disease (CAD) was associated with 1.74-fold higher mortality (HR: 1.74; 95% CI: 1.09-2.78; p = .021). Pre-EVAR AAA diameter and 1-year post-EVAR sac diameter were positively associated with mortality (HR: 1.05; 95% CI: 1.03-1.08; p < .001, and HR: 1.05; 95% CI: 1.03-1.07; p < .001, respectively), that is, an increase of pre-EVAR and/or 1-year post-EVAR AAA diameter by 1 mm was associated with a 5% higher risk of all-cause mortality. CONCLUSIONS: Reinterventions and treatment with ACE inhibitors or ARBs may be associated with decreased post-EVAR mortality. A greater pre-EVAR, a post-EVAR AAA diameter, CAD and chronic anticoagulation were associated with higher all-cause mortality post-EVAR.
RESUMO
The inferior vena cava (IVC) filter is an approved and effective device for prevention of pulmonary embolism. Despite declared effectiveness in prevention of pulmonary embolism, certain IVC filter-related complications have been described. This case report deals with successful endovascular retrieval of an IVC filter penetrating into the aorta. Learning objective: The use of inferior vena cava (IVC) filters has been associated with controversy in recent years, largely owing to concerns about the overuse. The perforation of IVC wall and further penetration of IVC filter struts into surrounding tissues belong to the most severe complication. The purpose of this report is to highlight potential severe complications associated with the use of IVC filter and to present the reader how the IVC filter-related complications can be successfully managed by endovascular treatment.
RESUMO
The internal mammary artery has become the primary conduit for the surgical revascularisation of the left anterior descending artery. Large side branches of internal mammary artery are typically ligated during cardiac surgery to avoid a potential coronary steal phenomenon. However, ligation of side branches can be unsuccessful due to the technically difficult surgical exploration of internal mammary artery branches. In this article, we present a case of a man who suffered from exertion angina pectoris despite successful surgical revascularisation of occluded left anterior descending artery by the internal mammary artery bypass. The coronary steal syndrome caused by the mighty side branch of internal mammary artery, that is, lateral costal artery was concluded as the reason of exertional angina. The endovascular procedure was performed and the lateral costal artery was successfully occluded using vascular plug. The occlusion of lateral costal artery has led to a complete disappearance of the exertional angina.
