Simultaneous reconstruction of multiple stiff wires from a single X-ray projection for endovascular aortic repair
ConclusionThe accuracy and speed of the proposed method allow for use in an intraoperative setting of deformation correction for EVAR.
Presence of gas is a frequent finding on early postoperative computed tomography angiography (CTA) after endovascular aortic aneurysm repair (EVAR) with unclear clinical relevance. The aim of this study was to examine and compare the presence of gas within the aneurysm sac following EVAR on early postoperative CTA after the use of carbon-dioxide (CO2) flushing technique with saline flushing alone.

CONCLUSION: The present data underline that ELIB is a non-negligible occurrence during long term EVAR follow up and requires further interventions, most often by endovascular solutions. According to the ELIB risk factors identified in this study, an iliac leg diameter oversize>10% and extensive common iliac artery coverage (
Abstract Background and objectives: Abdominal aortic aneurysm (AAA) growth is unpredictable after the endovascular aneurysm repair (EVAR). Continuing aortic wall degradation and weakening due to hypoxia may have a role in post-EVAR aneurysm sac growth. We aimed to assess the association of aortic wall density on computed tomography angiography (CTA) with aneurysm growth following EVAR. Materials and Methods: A total of 78 patients were included in the study. The control group consisted of 39 randomly assigned patients without aortic pathology. Post-EVAR aneurysm sac volumes on CTA were measured twice during the fo...
ConclusionThis case highlights the potential complications of using UFH anticoagulation following reversal of factor Xa inhibitors with andexanet alfa and underscores the importance of peri ‐procedural anticoagulation planning. For patients who require intra‐operative anticoagulation, providers should consider anticoagulation reversal with prothrombin complex concentrate instead of andexanet alfa or administration of a parenteral direct thrombin inhibitor, such as argatroban or bi valirudin during the surgical procedure.This article is protected by copyright.

ConclusionsThis study identified the sources of fusion error after insertion of rigid material during EVAR. As the sharpest angulation between aneurysm neck and sac increases, the overall accuracy of the fusion might be affected.
CONCLUSIONS: Older patients, those with female gender, and those with larger left iliac sealing diameters seem to experience higher rates of late srEL. Independent confirmation of these must be addressed in larger studies. PMID: 31160189 [PubMed - as supplied by publisher]
CONCLUSIONS: Higher preprocedural fibrinogen, absence of persistent type II endoleak and higher age were predictive factors of aneurysm sac regression post-EVAR. PMID: 30874486 [PubMed - as supplied by publisher]
A 78-year-old man underwent endovascular abdominal aortic aneurysm repair (EVAR) for a true aortic aneurysm. He developed sudden abdominal pain four hours after EVAR. Angiography revealed a dissected aneurysm of the middle colic artery (MCA). Despite conservative treatment, follow-up computed tomography revealed an expanded aneurysm of the MCA. We therefore performed coil embolization of the dissected MCA to prevent a rupture of the aneurysm. There has never been a reported case of acute dissection of the MCA immediately after EVAR that was not caused by catheters.
ConclusionEvidences from this study suggest that contrast-enhanced ultrasound scan post-EVAR can be utilised as safe and effective method in screening for endoleaks during post-EVAR surveillance without exposing the patient for additional risk of radiation and contrast. CEUS conveys no inferiority to CTA in detecting endoleaks.
