LEA 31. Endovascular Repair of Femoropopliteal Aneurysms
In this study, we analyzed our experience with endovascular therapy in the treatment of symptomatic and asymptomatic femoropopliteal artery aneurysms.
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 a...
In this case, a 79-year-old male presented with new anteroseptal Q waves and T-wave inversions across the precordial leads following an otherwise uneventful endovascular repair of his thoracoabdominal aortic aneurysm. The patient had no history of cardiac disease and had undergone a dobutamine stress echocardiogram within the preceding 6 months that showed no evidence of inducible ischemia. Nevertheless, routine postoperative electrocardiogram (EKG) revealed new Q waves and T-wave inversions and transthoracic echocardiogram that demonstrated akinesis of the left ventricle (LV) apex with chronic-appearing apical thrombus. W...
Abstract OBJECTIVES: The aim was to report indications, technical aspects, and outcomes of a multicentre experience of late open conversions (LOCs) after endovascular abdominal aneurysm repair (EVAR), in order to identify risk factors which may influence early morbidity and mortality rates, and long term survival. METHODS: Ten vascular centres retrospectively reviewed all patients requiring LOC (≥30 days from initial EVAR, undergoing total or partial endograft explantation) from 1996 to 2017. Baseline characteristics, endograft data, indications, procedural details, post-operative outcomes, and follow up d...
Controversy exists surrounding thoracic endovascular aortic repair (TEVAR) of chronic type B aortic dissection (cTBAD) because of concerns about durability. Entry tear coverage to induce false lumen (FL) thrombosis is thought to be an important determinant of subsequent aneurysm regression; however, septum compliance and distal re-entry tear retrograde FL perfusion coalesce to promote a dynamic remodeling environment between the true lumen (TL) and FL. There is a paucity of literature describing the influence of early remodeling events on subsequent risk of reintervention and survival for cTBAD.
This study examined the correlation between preoperative intraluminal thrombus and the incidence of type II endoleak and late sac expansion by measuring the thrombus volume.
Introduction: Persistent Type II Endoleak (PE II) has necessitated prolonged surveillance and requirement of re-intervention following infra-renal endovascular aneurysm repair (EVAR). The aim of this study was to assess the association of the percentage of aneurysmal sac thrombus (ST) with the incidence of PE II&subsequent re-intervention.
Introduction - The failure of endovascular repair of chronic aortic dissections can be explained by the back flow in the false channel through distal re-entry tears. After implantation of a thoracic stent-graft, the false lumen thrombosis occurs in only about 50% of the cases. We evaluated the feasibility of embolization of the false channel in chronic aortic dissections.
Introduction: The anatomy of the aortic neck influences the outcome of endovascular abdominal aneurysm repair (EVAR) and is defined severe (SPN) when at least one of the following characteristics, length, diameter, angle, and thrombus/calcification hamper a proper proximal sealing.1Aim of this study was to evaluate the individual role ofeach one of these characteristics on early and late EVAR outcomes.
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.
Introduction: Large aneurysm diameter represents a well-known predictor for late complications after EVAR. However, it is not clear whether this higher complication risk is attributable to the actual total diameter or to the thrombus-free lumen inside the AAA sac. We hypothesized that greater luminal volume, rather than total diameter, represents a more relevant risk factor for late complications after standard EVAR.
