Percutaneous thrombectomy of fat embolism in-transit.

We report the case of a previously independent 82-year-old female who experienced acute hemodynamic and respiratory deterioration requiring inotropic support due to a fat embolism during revision hip arthroplasty. Computed tomography pulmonary angiography demonstrated fat embolism, and transesophageal echocardiogram showed evidence of right ventricle strain and fat embolism in-transit in the right heart, as well as a moderate patent foramen ovale. Under transesophageal echocardiogram and intravascular ultrasound guidance, the Inari FlowTriever thrombectomy device was used successfully to retrieve the fat embolism with immediate hemodynamic improvement, no complications, and uneventful recovery.

5-years patency results of Zilver PTX on the femoro-popliteal arterial segment: A Northern Sydney experience.

Background: The burden of peripheral arterial disease is increasing. Treatment of femoro-popliteal lesions remains challenging despite novel endovascular devices. Drug-eluting stents suppress post-treatment inflammation and reducing neo-intimal hyperplasia to reduce in-stent restenosis.

Is There a Role for Heli-FX Endoanchors in Treating Type 1B Common Iliac Artery Endoleaks?

Objectives: The management of type 1B endoleaks following endovascular aortic aneurysm repair (EVAR) can be challenging. The Heli-FX Endoanchor system effectively treats proximal type 1A endoleaks but has not been used for type 1B common iliac artery endoleaks. This study demonstrates that it is both safe and effective in being used in the common iliac artery (CIA) limb of an EVAR.

AFX unibody stent graft: Effective and safe for the treatment of severe aorto-iliac occlusive disease.

Objectives: The primary objective of this study was to determine the primary, assisted primary and secondary patency rates of the Endologix AFX stent-graft in patients considered high risk for open surgery with complex aorto-iliac occlusive disease. The secondary objective was to determine 30-day major adverse cardiovascular and cerebrovascular events.

Methods: A retrospective review was undertaken of clinical records of 38 patients who underwent AFX stent-graft placement for aorto-iliac occlusive disease from 2016 to 2019.

A pilot study of the use of artificial intelligence with high-fidelity simulations in assessing endovascular procedural competence independent of a human examiner.

Background: With increased need for vascular surgery trainees to gain endovascular surgery proficiency, current models of case-numbers and subjective visual assessment are inadequate in capturing the skills required in endovascular surgery. We explored the use of high-fidelity simulators in (1) assessing endovascular surgical competence; (2) clinical decision making; and (3) the reliability of an artificial intelligence (AI) assessor.

Methods: Registrars, fellows and consultants from vascular surgery, interventional radiology and general surgery performed identical procedures on a high-fidelity simulator.

Editor's Choice - Optimal Timing of Thoracic Endovascular Aortic Repair for Uncomplicated Type B Aortic Dissection: A Systematic Review and Meta-Analysis.

Objective: Type B aortic dissections (TBAD) have a high mortality rate and are challenging to both classify and manage. There is significant evidence supporting the use of early intervention in complicated TBAD with thoracic endovascular aortic repair (TEVAR). Currently, there is equipoise regarding the optimal timing for TEVAR in TBAD.

Comparison of porcine and human acellular dermal matrix outcomes in wound healing: a deep dive into the evidence.

Acellular dermal matrices (ADM) are a novel graft. The goal of this systematic review is to evaluate the evidence behind differences in human and porcine ADM, irrelevant of manufacturing method, and to determine if there is enough of an evidence base to change clinical practice. An extensive literature search was performed through MEDLINE and Embase with search terms defining a population, intervention and outcome.

Evaluation of tools to assess operative competence in endovascular procedures: a systematic review.

Background: With an increase in the use of endovascular interventions as an alternative to open surgery and the unique technical skills required, current methods for assessing the competence of vascular surgery trainees may not be optimal, suggesting a need for a shift in assessment modalities. We conducted this systematic review to explore current assessment methods used in vascular surgery training to assess competence specific to endovascular procedures.

Methods: A comprehensive literature search was performed with a structured search strategy using terms focusing on endovascular procedures and assessment.

A systematic review of the effect of surgeon and hospital volume on survival in aortic, thoracic and fenestrated endovascular aneurysm repair.

Background: Endovascular aneurysm repair (EVAR) is becoming a mainstay in vascular surgery, both in metropolitan and regional hospitals. This review aims to assess the impact of hospital and surgeon volume on perioperative mortality specific to this surgery type to support the use of this treatment modality extensively.

Methods: A literature search was performed on multiple dedicated medical databases using a detailed search strategy with terms focusing on hospital volume and EVARs.

Optimizing Protein Harvest From Nasal Brushings for Determining Local Allergy Responses.

Background Rhinitis is a highly prevalent yet often misdiagnosed condition. Patients who have local allergic rhinitis are regularly mislabeled as having a nonallergic etiology. Thus, a highly accurate, reproducible, and noninvasive assessment, which can be performed quickly and with minimal discomfort to the patient, is required.
