Left Common Iliac Vein Stenting in a Case of Postural Orthostatic Tachycardia Syndrome/Pelvic Pain Overlap.

Postural orthostatic tachycardia syndrome (POTS) is mainly characterized by orthostatic intolerance and positional tachycardia although it frequently involves a myriad of non-specific symptoms that seem to overlap with existing medical conditions. Recent efforts have been made to further classify subtypes of POTS and associated conditions to better delineate underlying pathophysiology in an effort to guide diagnosis and tailor treatment. Here, we present a 22-year-old female with debilitating symptoms of POTS who reported pelvic pain on review of systems and underwent vascular ultrasound of the inferior vena cava, iliac veins, and bilateral lower extremities which revealed the characteristic left common iliac vein compression of May-Thurner syndrome prompting venous stenting which provided systemic symptomatic relief.

Managing Venous Thromboembolic Disease On-Call.

Managing venous thromboembolic disease on-call requires the interventional radiologist consider not only potential risk and benefit to the patient but also available resources in the IR suite as well as throughout the hospital, such as intensive care monitoring during treatment. We demonstrate how our practice manages these on-call cases ranging from deep venous thrombosis to acute pulmonary embolism and decide which patients need emergent treatment and which can undergo delayed intervention during working hours. In all cases, an adequate preprocedural clinical assessment is crucial.

Preoperative Computed Tomography-Guided Pulmonary Lesion Marking in Preparation for Fluoroscopic Wedge Resection-Rates of Success, Complications, and Pathology Outcomes.

Purpose: In this study, we describe our experience of lesion marking with fiducial markers (FM) and microcoils (MC) facilitating same-day surgical wedge resection, including success rates, pathology outcomes, and complications. We also explored patient/nodular characteristics associated with developing complications.

Materials And Methods: An IRB-approved single-institutional retrospective study of 136 patients who had 148 pulmonary nodules was conducted.

Percutaneous Image-Guided Cryoablation for the Treatment of Phantom Limb Pain in Amputees: A Pilot Study.

Purpose: To prospectively evaluate percutaneous image-guided nerve cryoablation for treatment of refractory phantom limb pain (PLP) in a pilot cohort for purposes of deriving parameters to design a larger, randomized, parallel-armed, controlled trial.

Materials And Methods: From January 2015 to January 2016, 21 patients with refractory PLP underwent image-guided percutaneous cryoneurolysis procedures. Visual analog scale scores were documented at baseline and 7, 45, and 180 days after the procedure.

Standardized Reporting in IR: A Prospective Multi-Institutional Pilot Study.

Purpose: To assess adoption and survey-based satisfaction rates following deployment of standardized interventional radiology (IR) procedure reports across multiple institutions.

Materials And Methods: Standardized reporting templates for 5 common interventional procedures (central venous access, inferior vena cava [IVC] filter insertion, IVC filter removal, uterine artery embolization, and vertebral augmentation) were distributed to 20 IR practices in a prospective quality-improvement study. Participating sites edited the reports according to institutional preferences and deployed them for a 1-year pilot study concluding in July 2015.

The Impact of Nonphysician Providers on Diagnostic and Interventional Radiology Practices: Operational and Educational Implications.

The numbers of nurse practitioners (NPs) and physician assistants (PAs) are increasing throughout the entire health care enterprise, and a similar expansion continues within radiology. The use of radiologist assistants is growing in some radiology practices as well. The increased volume of services rendered by this growing nonphysician provider subset of the health care workforce within and outside radiology departments warrants closer review, particularly with regard to their potential influence on radiology education and medical imaging resource utilization.

The impact of nonphysician providers on diagnostic and interventional radiology practices: regulatory, billing, and compliance perspectives.

The numbers of nurse practitioners and physician assistants are increasing throughout the entire health care enterprise, and a similar expansion continues within radiology. Some practices have instead embraced radiologist assistants. The increased volume of services rendered by this growing nonphysician provider subset of the health care workforce within and outside of radiology departments warrants closer review.

Characterizing cardiopulmonary arrest during interventional radiology procedures.

Purpose: Careful case selection and preparation can prevent most cardiopulmonary arrest (CPA) in the interventional radiology (IR) suite. A series of CPAs was analyzed to provide insight into risk factors for these events.

Materials And Methods: A single-institution CPA database was used to identify all code team activations from January 1, 2005, to May 30, 2011, in the IR department.

Incidence and management of inferior vena cava filter thrombus detected at time of filter retrieval.

Purpose: To evaluate inferior vena cava (IVC) venograms (ie, cavograms) before filter retrieval to determine the incidence and volume of filter thrombus relative to filter dwell time and evaluate subsequent changes in thrombus volume with additional anticoagulation.

Materials And Methods: IVC filter retrieval attempts between December 2002 and June 2010 were retrospectively reviewed to determine the incidence of filter thrombus and estimate thrombus volume on a preretrieval cavogram. Correlation between filter dwell times (assessed at 30-d intervals) and incidence and volume of thrombus was assessed.
