The Third and Fourth Dimensions of EVAR
In an intuitive retrospective study of 404 endovascular aneurysm repair (EVAR) patients, Oliveira-Pinto et al.1 investigated the relationship between pre-operative abdominal aortic aneurysm (AAA) sac luminal volume (i.e. sac volume minus thrombus volume) and aneurysm related morbidity, secondary interventions, and mortality. The authors found that patients in the highest luminal volume quartile had sig nificantly wider, shorter, and more angulated proximal necks. Additionally, these high luminal volume AAAs demonstrated a significantly increased five year risk of AAA related complications which remained robust even after adjusting for endograft instructions for use compliance.
The present study evaluates aneurysmal sac remodeling and the loss of intercostal arteries after the first step of staged treatment of thoraco-abdominal aortic aneurysms (TAAA). The purpose of this approach is to keep the aneurysmal sac temporarily perfused in order to induce progressive thrombosis of the aneurysm while simultaneously allowing the spinal cord to establish adequate perfusion thereby promoting the development of collateral circulation.
Large aneurysm diameter represents a well known predictor of late complications after endovascular aneurysm repair (EVAR). However, the role of the thrombus free lumen inside the abdominal aortic aneurysm (AAA) sac is not clear. It was hypothesised that greater luminal volume represents a relevant risk factor for late complications after EVAR.
es FB Abstract OBJECTIVE: Large aneurysm diameter represents a well known predictor of late complications after endovascular aneurysm repair (EVAR). However, the role of the thrombus free lumen inside the abdominal aortic aneurysm (AAA) sac is not clear. It was hypothesised that greater luminal volume represents a relevant risk factor for late complications after EVAR. METHODS: A retrospective cohort analysis was performed including all patients undergoing EVAR from 2005 to 2016 at a tertiary referral institution. Pre-operative AAA lumen volume was measured in centre lumen line reconstructions and patien...
The goal of this study was to verify whether the amount of intraluminal thrombus (ILT) within the aneurysm sac is associated with the outcomes of abdominal aortic aneurysm (AAA) after endovascular aneurysm repair (EVAR).
AbstractGuidelines advice against dual antiplatelet therapy (DAPT) discontinuation less than 12 months after percutaneous coronary intervention with drug-eluting stents (DES-PCI). However, any delay of necessary surgery in patients with descending thoracic (DTA) or abdominal aortic aneurysm (AAA), treated by DES-PCI, increases the risk of aneurysm rupture/dissection. We evaluated the safety of 8-week waiting time between DES-PCI and endovascular aortic repair (EVAR). 1152 consecutive patients with coronary artery disease (CAD) needing elective DTA or AAA repair were enrolled and divided into two groups. Group A inclu...
ConclusionSWS has the potential to detect endoleaks in AAA after EVAR with comparable sensitivity to CTA and superior sensitivity to CDUS.Key Points• Dynamic elastography with shear wave sonoelastography (SWS) detected 100% of endoleaks in abdominal aortic aneurysm (AAA) follow-up that were identified by a combination of CT angiography (CTA) and color Doppler ultrasound (CDUS).• Based on elasticity maps, SWS differentiated endoleaks from thrombi within the aneurysm sac (p
Introduction - Shaggy aorta is related to early adverse events following endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm, specially peripheral and visceral embolization from the aorta.
Thrombosis of an endovascular aortic repair (EVAR) is a devastating complication of a common surgical procedure that can lead to serious morbidity and mortality if not promptly recognized. This is the first case report of an EVAR graft thrombosis in the emergency medicine literature.
Postimplantation syndrome (PIS) is a systemic inflammatory response occurring in an early phase after abdominal aortic aneurysm (AAA) endovascular repair (EVAR). The pathophysiology underlying PIS is not yet well understood. It is speculated that the type of the stent graft or the mural thrombus within the AAA may play a role in determing this inflammatory response. At present, there is no consensus about the influence of PIS on clinical outcomes during follow-up. The endovascular aneurysm sealing (EVAS) with the Nellix sac-anchoring endoprosthesis (Nellix Endovascular, Palo Alto, Calif) is a novel modality for AAA repair ...
ConclusionThe endovascular neck stabilization is a useful treatment option that facilitates standard EVAR for AAA in chronic aortic dissection.
