Lower Extremity Revascularization Using Optical Coherence Tomography-Guided Directional Atherectomy: Final Results of the EValuatIon of the PantheriS OptIcal COherence Tomography ImagiNg Atherectomy System for Use in the Peripheral Vasculature (VISION) Study.

Purpose: To evaluate the safety and efficacy of a novel optical coherence tomography (OCT)-guided atherectomy catheter in treating patients with symptomatic femoropopliteal disease.

Methods: The VISION trial ( ClinicalTrials.gov identifier NCT01937351) was a single-arm, multicenter, global investigational device exemption study enrolling 158 subjects (mean age 67.

Clinical outcome of an extended proximal seal zone with the AFX endovascular aortic aneurysm system.

Objective: Despite improvements in endograft technology, operator skill, and patient selection, endovascular aneurysm repair continues to be associated with device-related complications. A retrospective, observational study was undertaken to evaluate the clinical outcome and imaging findings of a unique device having externally-mounted, conformable graft material.

Methods: Infrarenal abdominal aortic aneurysms were treated with the Endologix, Inc AFX endovascular aortic aneurysm system (Irvine, Calif) endograft in 108 consecutive patients over a 25-month period at two U.

Final results of the Chronic Total Occlusion Crossing With the Ocelot System II (CONNECT II) study.

Purpose: To evaluate the safety and effectiveness of the optical coherence tomography-guided Ocelot catheter to cross femoropopliteal chronic total occlusions (CTOs).

Methods: The CONNECT II study was a prospective, multicenter, non-randomized single-arm study of the safety and effectiveness of the Ocelot catheter in CTO crossing. Key inclusion criteria were a 99% to 100% stenosed femoropopliteal segment, lesion length between 1 and 30 cm, and resistance to guidewire crossing.

Crossing chronic total occlusions with the Ocelot system: the initial European experience.

Aims: The aim of the study was to determine the safety, efficacy and feasibility of a new chronic total occlusion (CTO) device using optical coherence tomography (OCT) technology, the Ocelot catheter (Avinger, Inc., Redwood City, CA, USA), for crossing of SFA CTOs following guidewire failure.

Methods And Results: Prospective, multicentre, market preference testing.

Endovascular repair of a chronic aortocaval fistula using a thoracic aortic endoprosthesis.

Penetrating abdominal trauma with injury to the aorta and vena cava usually requires emergent intervention and is frequently lethal. Formation of a chronic aortocaval fistula (ACF) is an uncommon late complication of these injuries. We report a case of an ACF presenting 17 years after a gunshot wound to the abdomen, with progressive congestive heart failure as the presenting symptom.

Recurrence of chronic venous ulcers on the basis of clinical, etiologic, anatomic, and pathophysiologic criteria and air plethysmography.

Introduction: Leg ulcers associated with chronic venous insufficiency (CVI) frequently recur after healing. The risk of recurrence has not been well defined for patients in different anatomic and hemodynamic groups. We reviewed the risk of ulcer recurrence on the basis of clinical, etiologic, anatomic, and pathophysiologic criteria and hemodynamic characteristics of the affected limb as assessed with air plethysmography (APG).
