Evar

BACKGROUND: Endovascular aortic repair (EVAR) is a less invasive method than the more physiologically stressful open surgical repair (OSR) for patients with anatomically appropriate abdominal aortic aneurysm (AAA). Early postoperative outcomes are associated with both patients' physiologic reserve and the physiologic stresses of the surgical intervention. Among frail patients with reduced physiologic reserve, the stress of an aortic rupture in combination with the stress of an operative repair are less well tolerated, raising the risk of complications and mortality...

INTRODUCTION: Endovascular aortic repair (EVAR) was originally designed as a treatment modality for patients with abdominal aortic aneurysms (AAAs) deemed unfit for open repair. However, the definition of "unfit for open repair" is largely subjective and heterogenous. The purpose of this study was to compare patients deemed unfit for open repair who underwent EVAR to a matched cohort who underwent open repair for infrarenal AAAs. METHODS: The Vascular Quality Initiative (VQI) of the Society for Vascular Surgery (SVS) was queried for patients who underwent EVAR and open infrarenal AAA repair from 2003-2022...

Background: The aim of this study was to assess the prognostic role of frailty and sarcopenia on the survival of patients with AAA undergoing elective endovascular repair (EVAR). Methods: A systematic review of the literature was conducted in accordance with Meta-analysis of Observational Studies in Epidemiology (MOOSE). The association of frailty or sarcopenia with 30-day mortality and late survival was expressed as odds ratios (ORs) or hazard ratios (HRs) with a 95% confidence interval (CI). Meta-analysis random effects models were applied...

BACKGROUND: It is estimated that 22-57% of vascular patients are lost to follow-up (LTF) which is of concern as the Society of Vascular Surgery recommends annual patient follow-up. The purpose of this report was to identify social determinants of health factors (SDoH) and their relationship to LTF in vascular patients. METHODS: The methods employed were a systematic literature review of 29 empirical articles and a retrospective quality improvement report with 27 endovascular aortic repair (EVAR) and thoracic endovascular aortic repair (TEVAR) patients at the University of Chicago...

BACKGROUND: The aim of this study is to investigate the relationship between HALP score and post-contrast acute kidney injury (PC-AKI) and average 6-year mortality in patients undergoing endovascular abdominal aortic aneurysm repair (EVAR). METHODS: 125 patients who underwent EVAR between January 2015 and December 2020 were included in our study. HALP score was calculated with the formula "hemoglobin × albumin × lymphocyte count/platelet count." In the first phase of the study, two groups were developed: those who developed PC-AKI and those who did not...

OBJECTIVES: EVAR is the preferred treatment modality for patients with an infrarenal abdominal aortic aneurysm with suitable anatomy. Each manufacturer of aortic stentgrafts has specific anatomic requirements. In some patients, it is not possible to adhere to the instructions for use, but alternative treatment is also not possible. In these patients, EVAR can be performed outside instructions for use. METHODS: In this study, all consecutive patients in whom an Endurant II or IIS stentgraft was used between 1 January and 31 December were reviewed...

BACKGROUND: Hospital volume is associated with mortality after open aortic aneurysm repair. Fenestrated and branched endovascular aortic repair (B-FEVAR) has been increasingly used for repair of complex thoracoabdominal and juxtarenal aneurysms but evidence of a center-volume relationship is limited. We aimed to measure the association of center volume with in-hospital mortality, post-operative outcomes and 1-year survival following B-FEVAR. METHODS: Patients undergoing elective endovascular thoracoabdominal and complex abdominal aneurysm repair with branch intervention (2014-2021) listed within the national Vascular Quality Initiative Thoracic Endovascular Aortic Repair (TEVAR)/complex EVAR database were analyzed...

BACKGROUND: A 2023 Cochrane review showed no difference in bleeding/wound infection complications, short-term mortality and aneurysm exclusion between the percutaneous and cut-down approach for femoral access in endovascular aortic aneurysm repair (EVAR). In contrast, single-center studies have shown bilateral cutdown resulting in higher readmission rates due to higher rates of groin wound infections. Whether 30-day readmission rates vary by type of access during EVAR procedures is unknown...

OBJECTIVES: Almost half of endovascular aortic aneurysm repair (EVAR) procedures are performed in hostile anatomy, increasing the risk of procedure related complications such as type IA endoleaks, which may be prevented with the chimney technique in EVAR (ChEVAR). Our aim is to describe the differential characteristics between EVAR in favorable anatomy and ChEVAR in hostile necks. MATERIALS AND METHODS: A cohort of patients with infrarenal abdominal aortic aneurysms (AAA) that were treated with EVAR or ChEVAR were included...

Hostile aortic neck anatomy challenges the outcomes of endovascular abdominal aortic aneurysm repair (EVAR). Besides reverting to open surgical repair (OSR), thoughtful endograft selection and a number of advanced endovascular techniques have been suggested as potential solutions for preventing proximal seal zone complications, improving EVAR durability, and preventing aneurysm-related death. Each technique is associated with advantages and limitations and there has not been a credible direct comparison amongst them in the form of a well-designed prospective trial...

INTRODUCTION: Dyslipidemia is common in patients with abdominal aortic aneurysm (AAA). However, there is insufficient research on the impact of dyslipidemia on the postoperative outcomes of patients with AAA after endovascular aortic aneurysm repair (EVAR). This study aimed to determine the impact of dyslipidemia on the prognosis of patients with AAA treated with EVAR. METHOD: We retrospectively reviewed patients with AAA who underwent EVAR at our hospital between 2010 and 2020...

BACKGROUND: Air embolism is a known risk during thoracic endovascular aortic repair (TEVAR) and is associated with an incomplete deairing of the delivery system despite the saline lavage recommended by the instructions for use (IFU). As the delivery systems are identical and residual air remains frequently in the abdominal aortic aneurysm sac, endovascular aortic repair (EVAR) can be used to examine the effectiveness of deairing maneuvers. We aimed to evaluate whether increasing the flush volume can result in a more complete deairing...

INTRODUCTION: The study aims to describe midterm outcomes following treatment of infrarenal abdominal aortic aneurysms (AAAs) with short necks by endosutured aneurysm repair (ESAR) using the Heli-FX EndoAnchor system. METHODS: This is a retrospective study of prospectively collected data from nine vascular surgery departments between June 2010 - December 2019, including treated AAAs with neck lengths ≤ 10mm. The decision for the use of EndoAnchors was made by the treating surgeon or multidisciplinary aortic committee according to each centre's practice...

RATIONALE: A hostile iliac access route is an important consideration when enforcing endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAA). Herein, we report a case of AAA with unilateral external iliac artery occlusion, for which bifurcated EVAR was successfully performed using a single femoral and brachial artery access. PATIENT CONCERNS: A 76-year-old man who had undergone surgery for lung cancer 4.5 years prior was diagnosed AAA by computed tomography (CT)...

INTRODUCTION: Ruptured abdominal aortic aneurysms (AAAs) pose an immediate threat for patient's life and endovascular repair (EVAR) is currently the preferred treatment modality in the presence of suitable anatomy. This is determined based on the requirements of each endograft as described in the instructions for use (IFU). The new ALTO system (Endologix, Irvin, CA, U.S.A.), can accommodate a great range of anatomies such as short necks and/or narrow access, but its unique design requires specific technical modifications during treatment of ruptured AAAs...

PURPOSE: To assess the feasibility and safety of intravascular lithotripsy (IVL) for enabling transfemoral abdominal (EVAR), thoracic (TEVAR), and thoracoabdominal (BEVAR) endovascular aneurysm repair in patients with narrow and calcified iliac arteries. MATERIALS AND METHODS: Consecutive patients treated with IVL for severe calcified and narrowed iliac access before EVAR, TEVAR, or BEVAR between November 2020 and June 2022 were retrospectively evaluated. All anatomical iliac characteristics were acquired by multi-planar reconstruction of preoperative computed tomography angiography (CTA)...

INTRODUCTION: Horseshoe kidney (HK) is an anatomical variant characterised by abnormalities in the position, rotation, and vascular supply of the kidney, with functioning renal masses on both sides of the vertebral column fused together at the isthmus. Due to the altered pattern of kidney vasculature, endovascular aortic repair for aortic abdominal aneurysm (AAA) in the presence of HK requires vascular anatomy specific planning. REPORT: A 68 year old male, with multiple comorbidities, presented with an asymptomatic AAA and HK...

As the use of endovascular aneurysm repair (EVAR) increases, anatomic constraints remain a challenge. In this case report, we describe the use of intravascular lithotripsy to facilitate EVAR in a patient with a severely calcified and stenotic aortic bifurcation. Future applications of intravascular lithotripsy could help expand the use of EVAR to patients with severely stenotic vasculature and optimize outcomes in the treatment of infrarenal abdominal aortic aneurysms.

OBJECTIVE: To evaluate the long-term outcomes of standard endovascular aneurysm repair (S-EVAR) of juxtarenal abdominal aortic aneurysms (JAAAs). METHODS: Data of patients with JAAAs who were unsuitable for fenestrated endovascular aneurysm repair (F-EVAR) and open repair (OR) and underwent treatment from January 2015 to December 2021 were retrospectively reviewed. Computed tomography angiography and ultrasonography of the aorta were performed before discharge, at 6 and 12 months postoperatively, and annually thereafter...
