Improved technique for sheath supported contralateral limb gate cannulation in endovascular abdominal aortic aneurysm repair.

Improved technique for sheath supported contralateral limb gate cannulation in endovascular abdominal aortic aneurysm repair. Vasa. 2019 Sep 24;:1-4 Authors: Pakeliani D, Lachat M, Blohmé L, Kobayashi M, Chaykovska L, Pfammatter T, Puippe G, Veith FJ, Pecoraro F Abstract Background: To present a technique of sheath supported contralateral limb gate (CLG) cannulation of modular bifurcated stent-graft in endovascular abdominal aortic repair. Materials and methods: After totally percutaneous bilateral femoral access, the 9F introducer sheath is exchanged to a 30 cm 12 fr introducer sheath over a stiff wire contralateral to the intended main stent-graft insertion side and advanced into the aorta below the lowest renal artery. Parallel to the stiff wire within the sheath an additional standard J-tip guidewire with a 5 fr Pigtail angiographic catheter is advanced to the level of the renal arteries. After main body deployment, the 12 fr introducer sheath and J-tip wire with pigtail catheter are retracted until the CLG opening level, maintaining the stiff "buddy" wire in position to support the 12 fr sheath, maintaining its distal opening close to the contralateral gate opening to achieve easy cannulation. Results: Retrospective analysis of video archive from July 2016 to February 2018 evidenced 55 recorded EVAR cases. All CLG cannulations were obtained with Standard J-tip or Terumo Glidewire wires and with Pig-Tail or Berenstein catheters...

This report describes the rapid expansion of a previously excluded abdominal aortic aneurysm (AAA) following type A aortic dissection repair in a 74-year-old male. Following successful hemi-arch replacement, CT angiography (CTA) showed residual dissection throughout the thoracoabdominal aorta which had created a proximal endoleak at the prior endovascular stentgraft resulting in rapid growth of the residual AAA sac. Urgent thoracic endovascular aortic repair (TEVAR) did not fully obliterate false lumen flow allowing further unstable expansion of the AAA and abdominal pain.

Objectives The aim of this study was to compare image quality, conspicuity, and endoleak detection between single-energy low-kV images (SEIs) and dual-energy low-keV virtual monoenergetic images (VMIs+) in computed tomography angiography of the aorta after endovascular repair. Materials and Methods An abdominal aortic aneurysm phantom simulating 36 endoleaks (2 densities; diameters: 2, 4, and 6 mm) in a medium- and large-sized patient was used. Each size was scanned using single-energy at 80 kVp (A) and 100 kVp (B), and dual-energy at 80/Sn150kVp for the medium (C) and 90/Sn150kVp for the large size (D). VMIs+ at 40 k...

Introduction: This is a study designed to assess the effectiveness of the new Angio PLanewave UltraSensitive imaging (Angio PL.U.S.) method as a non-invasive alternative to Contrast-Enhanced Ultrasound (CEUS) and Computed Tomography Angiography (CTA) for endoleak detection and classification in patients followed up after endovascular abdominal aortic aneurysm repair (EVAR). The authors emphasize the potential role of Angio PL.U.S. in patients undergoing post-EVAR follow-up.

ConclusionCombined endovascular aneurysm repair and on-pump beating heart coronary artery bypass grafting in a one-stage operation is a promising strategy to improve therapeutic efficiency in octogenarians. More studies are needed to compare the efficacy and safety of one-stage and two-stage operations to treat concomitant coronary artery disease and aortovascular pathology in the high-risk octogenarian patients.

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.

This study describes detailed methodology and validation of endovascular aortic repair (EVAR) simulation using 3D printed AAA model connected to hemodynamic pump.MethodThe AAA model was printed with Objet500 Connex3 (Stratasys, Eden Prairie, MN) and connected to BDC PD-0500 fluid pump (BDC Laboratories, Wheat Ridge, CO). EVAR procedure metrics were benchmarked in two expert implanters and compared to 20 vascular surgical trainees with different levels of EVAR experience (

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]
