Clinical Assessment of Peripheral Arterial Disease in the Office: What Do the Guidelines Say?

Lower extremity peripheral arterial disease (PAD) is the manifestation of atherosclerotic disease within the lower extremities. The presentation of PAD is diverse ranging from asymptomatic disease to claudication or to debilitating rest pain, nonhealing ulcers, and gangrene. PAD is associated with significant morbidity, mortality, and healthcare costs. Proper diagnosis and management of PAD is important so as to maintain quality of life and reduce the risk of cardiovascular disease and adverse limb events such as amputation. This document provides a comprehensive outpatient approach to the clinical assessment of PAD that includes risk factors, diagnosis, treatment, and follow-up options

Infrapopliteal Artery Occlusive Disease: An Overview of Vessel Preparation and Treatment Options

Critical limb ischemia (CLI) is defined as chronic rest pain and/or the presence of tissue loss (ulcers or gangrene) in the lower extremities secondary to ischemia. CLI is a limb and potentially life-threatening disease associated with a poor prognosis with only 50% of patients being able to preserve both limbs within 12 months of diagnosis. CLI related to diabetes is often more extensive with multi-level long segmental arterial disease resulting in a 5–30-fold increased rate of amputation. As the incidence and prevalence of diabetes mellitus increases within our aging society, the rate of infrapopliteal artery occlusive disease (IPOD) and the need for intervention rises with it. The aim of this manuscript is to provide the reader with an overview of the various devices available for vessel preparation (VP) and treatment of IPOD in order to optimize patency rates, symptom resolution, healing of wounds, and minimize complications

Prostate Arterial Anatomy: A Primer for Interventional Radiologists

Identification of the prostatic arteries (PAs) is one of the most challenging aspects of prostate artery embolization for treatment of benign prostatic hyperplasia-associated lower urinary tract symptoms. Operators require a detailed understanding of the prostate arterial anatomy to ensure technical and clinical success with minimal complications. Due to substantial variability in internal iliac artery branch patterns and specifically the origin of the PA, we focus on 3 clinically relevant classification systems used to categorize the pelvic vasculature. These include classification systems to understand the internal iliac artery branching pattern, PA origin variation, and intraprostatic branching

Robotic en bloc first-rib resection for Paget-Schroetter disease, a form of thoracic outlet syndrome: technique and initial results

Objective First-rib resection is a key component of the treatment of Paget-Schroetter disease. There are many controversies regarding the management of this disease. We report a safe, effective, minimally invasive robotic transthoracic approach for resection of the first rib. Methods Over an 8-month period, five patients underwent robotic first-rib resection. Preoperative assessment included physical examination and bilateral venous angiography. On a thoracoscopic platform using three 2-cm incisions and one 1-cm incision, the robot was used to dissect the first rib and divide the scalene muscles. Success of the first-rib resection was assessed by postoperative venous angiography. Results There were four men and one woman. Mean age was 34.6 ± 10 years. Mean operative time was 195 ± 24.6 minutes. There were no complications and no mortality. All patients had a patent subclavian vein on the postoperative venogram and were anticoagulated with warfarin for 3 months. At a median follow-up of 12 months, all patients had an open subclavian vein for a patency rate of 100%. Conclusions Robotic thoracoscopic first-rib resection represents a feasible minimally invasive approach to en bloc resection of the first rib. This technique minimizes the risk of neurovascular complications that are associated with conventional techniques. </jats:sec

Three-Dimensional Printing for Procedure Rehearsal/Simulation/Planning in Interventional Radiology

With the advances in affordable three-dimensional (3D) printing technology, 3D reconstruction and patient-specific 3D printed models are establishing a crucial role in the field of medicine for both educational purposes and procedural planning. 3D printed models provide physicians with increased 3D perception and tactile feedback, and enable a team-based approach to operational planning. However, performing an effective 3D reconstruction requires an in-depth understanding of the software features to accurately segment and reconstruct the human anatomy of interest from preacquired image data from multiple modalities such as computer tomography, 3D angiography and magnetic resonance imaging, and the different 3D printers/materials available in the market today. Increased understanding of this technology may benefit radiologists by developing techniques and tricks specific to interventional radiology and establishing a criterion to determine when to use these. Thus, the purpose of this manuscript is to provide physicians with an update on currently available 3D reconstruction software as well as printers and materials. Our initial experience using this technology is introduced based on a specific case of developing a 3D printed aorta for a patient with severe stenosis of the abdominal aorta

The "Woundosome" Concept and Its Impact on Procedural Outcomes in Patients With Chronic Limb-Threatening Ischemia

This editorial assembles endovascular specialists from diverse clinical backgrounds and nationalities with a global call to address key challenges to enhance revascularization in chronic limb-threatening ischemia (CLTI) patients.- Dedicated below-the-ankle (BTA) angiography and revascularization is underutilized in ischemic foot treatment. Existing guidelines do not address comprehensive BTA vessel analysis. CLTI trials also often lack data on in-line arterial flow to the ischemic lesion and BTA vessel evaluation, hindering outcome assessment.- Dedicated multi-planar angiographic evaluation of the distal microcirculation is key: Direct arterial flow or good-quality collaterals are crucial in influencing wound healing and need to be assessed diligently to the level of the distal ischemic wound territory, termed “woundosome.”- An important primary emphasis of future trials should be on validating technologies and strategies for assessing tissue perfusion before, during, and after revascularization undertaken to heal tissue loss in CLTI patients. This will allow determination of a potentially significant delta in tissue perfusion prior to and following intervention at the “woundosome” level. Once changes in arterial perfusion have been identified as positively correlated to wound healing, these could serve as a much-needed novel primary technical outcome measure for patients with tissue loss undergoing surgical, hybrid, or endovascular revascularization
