Purpose: To evaluate the feasibility, safety, and outcome of transcatheter embolization using ethylene vinyl alcohol copolymer (EVOH) of type I endoleaks associated with endovascular abdominal aortic aneurysm repair. Patient Population and Methods: Retrospective chart review was performed to identify 8 consecutive patients who had undergone EVOH embolization for type I endoleaks between 2012 and 2015. The primary approach used to access the endoleak was the perigraft technique, where the endoleak itself is catheterized at the anastomotic site. Results: Six type Ia and 2 type Ib endoleaks were treated. In 2 patients, a direct transabdominal approach was used to access the endoleak because it was inaccessible via the perigraft approach. Coils were used in addition to EVOH in 5 cases. Residual endoleak was noted in 1 case, whereas 2 patients developed a recurrent type I endoleak during follow-up. No EVOH complications were observed. The 5 remaining patients demonstrated freedom from endoleak and reintervention at a mean follow-up of 6.9 months. Conclusion: Type I endoleaks can be safely and effectively treated by embolotherapy with EVOH. Larger endoleaks resulting from grossly undersized endografts appear to be unsuitable for EVOH embolization.

Abstract. Background: Biomarkers reflecting diverse pathophysiological pathways may play an important role in the pathogenesis of abdominal aortic aneurysm (aortic diameter ≥30 mm, AAA), levels of many biomarkers are elevated and correlated to aortic diameter among 65-year-old men undergoing ultrasound (US) screening for AAA. Probands and methods: To evaluate potential relationships between biomarkers and aortic dilatation after long-term follow-up, levels of C-reactive protein (CRP), proneurotensin (PNT), copeptin (CPT), lipoprotein-associated phospholipase 2 (Lp-PLA2), cystatin C (Cyst C), midregional proatrial natriuretic peptide (MR-proANP), and midregional proadrenomedullin (MR-proADM) were measured in 117 subjects (114 [97 %] men) aged 47–49 in a prospective population-based cohort study, and related to aortic diameter at US examination of the aorta after 14–19 years of follow-up. Results: Biomarker levels at baseline did not correlate with aortic diameter after 14–19 years of follow up (CRP [r = 0.153], PNT [r = 0.070], CPT [r = –.156], Lp-PLA2 [r = .024], Cyst C [r = –.015], MR-proANP [r = 0.014], MR-proADM [r = –.117]). Adjusting for age and smoking at baseline in a linear regression model did not reveal any significant correlations. Conclusions: Tested biomarker levels at age 47–49 were not associated with aortic diameter at ultrasound examination after 14–19 years of follow-up. If there are relationships between these biomarkers and aortic dilatation, they are not relevant until closer to AAA diagnosis.

We present a case of a 72-year-old male with an abdominal aortic aneurysm status post-endovascular aneurysm repair (EVAR). Follow-up imaging demonstrated an enlarging type II endoleak and attempts at transarterial coil embolization of the inferior mesenteric artery were unsuccessful. The patient underwent image-guided percutaneous translumbar type II endoleak repair using XperGuide (Philips, Andover, MA USA).

Purpose: The aim of the present study was to investigate a potential difference on the arterial stiffness among aneurysm patients and non-aneurysm controls, as well as to explore potential changes between patients treated either with endovascular or open repair. Materials and Methods: A 110 patients with an infrarenal AAA were prospectively enrolled in this study. Fifty-six patients received an EVAR, whereas 54 patients received an open surgical repair. Moreover, 103 gender and age-matched subjects without AAA served as controls. The cardio-ankle vascular index (CAVI) was applied for measurement of the arterial stiffness. Results: CAVI values were statistically higher in the AAA patients when compared with control subjects. Although at 48 hours postoperatively the CAVI values were increased in both groups when compared to baseline values, the difference in CAVI had a tendency to be higher in the open group compared to the endovascular group. At 6 months of follow up the CAVI values returned to the baseline for the patients of the open repair group. However, in the endovascular group CAVI values remained higher when compared with the baseline values. Conclusion: Patients with AAAs demonstrated a higher value of CAVI compared to healthy controls. A significant increase of arterial stiffness in both groups during the immediate postoperative period was documented. The increase in arterial stiffness remained significant at 6 months in EVAR patients. Further studies are needed to elucidate the impact of a decreased aortic compliance after stentgraft implantation on the cardiac function of patients with AAA.

Abstract Funding Acknowledgements Type of funding sources: None. Background Upper gastrointestinal bleeding (UGIB) is the most common hemorrhagic complication in stable CAD patients receiving antithrombotic therapy. It seems that atherosclerotic burden may increase the overall bleeding frequency. However, this factor has never been taken into account with UGIB risk assessment. We aimed to assess the predictive value of atherosclerotic burden (peripheral atherosclerosis – PAD and abdominal aortic aneurysm - AAA) for UGIB in patients with stable CAD receiving long-term antithrombotic therapy. Patients and Methods. A single center prospective Registry of Long-term AnTithrombotic TherApy (REGATTA-1 NCT04347200) included 934 pts with stable CAD (78.6% males, median age 61 [IQR 53-68] yrs). 77,3 %  of patients received dual antiplatelet therapy due to recent PCI with a switch to aspirin monotherapy after 6 months. 17,6% of patients received aspirin only, 5,1 % of patients received oral anticoagulants because of concomitant atrial fibrillation. Risk assessment of UGIB was performed according to the 2015 European Society of Cardiology guidelines (we were not able to identify only Helicobacter pylori infection). Additional ultrasound screening for PAD (lower limbs and cerebrovascular beds) and AAA was applied. The primary outcome was any overt UGIB (BARC ≥2). Results  The frequency of PAD was 18,8%, AAA – 2,4%, PAD and/or AAA -  20,5%. In a total 2335 person-years of follow-up (median follow-up - 2,5 yrs, IQR 1,1 – 5.1), UGIB occurred in 51 patients (incidence at 1 year 1,9 per 100 patients).  The median time to first occurrence of UGIB was 72 [IQR 13-214] days. Comparing the Kaplan-Meyer curves, the UGIB developed three times more often in patients with coexisted PAD and/or AAA vs isolated CAD (19.8% vs 6.5%, Log-Rank p = 0.00006). The difference remains consisted in regression model taking in account 2015 ESC panel of UGIB risk factors (OR 3.4; CI 1.7–6.9, p = 0,0005). Conclusions Atherosclerotic burden (concomitant PAD and/or AAA) is an independent predictor of UGIB in patients with stable CAD receiving long-term antithrombotic therapy.

Objectives We represent two cases of late proximal type I endoleak following EVAR with aneurysm expansion that were treated with a custom-made graft with inner branches. Methods Two patients of 87 and 82 years old were operated by EVAR 6 and 8 years ago for abdominal aortic aneurysm. Both had proximal type I endoleak with aneurysm sac expansion. Open surgery had a high risk, and a proximal aortic extension with a simple aortic cuff was not possible neither because previous EVAR grafts were already at the level of the renal arteries. A custom-made endograft with inner branches was planned as a fenestrated graft was not technically possible. Results We successfully treated both patients using a custom-made graft with four inner branches from Jotec (Cryolife, Kennesaw, GA). Three months’ follow-up CT scan did not show any endoleaks. All target vessels were patent with good conformability of the bridging stents. Conclusion The treatment of proximal type I endoleak using inner branches’ endografts is feasible. This novel technology might broaden the indications for complex aortic repair in a group of patients where fenestrated endografts are not possible.
