  • Creation of an iOS and Android Mobile Application for Inferior Vena Cava (IVC) Filters: A Powerful Tool to Optimize Care of Patients with IVC Filters SEMINARS IN INTERVENTIONAL RADIOLOGY Deso, S. E., Idakoji, I. A., Muelly, M. C., Kuo, W. T. 2016; 33 (2): 137-143

    Abstract

    Owing to a myriad of inferior vena cava (IVC) filter types and their potential complications, rapid and correct identification may be challenging when encountered on routine imaging. The authors aimed to develop an interactive mobile application that allows recognition of all IVC filters and related complications, to optimize the care of patients with indwelling IVC filters. The FDA Premarket Notification Database was queried from 1980 to 2014 to identify all IVC filter types in the United States. An electronic search was then performed on MEDLINE and the FDA MAUDE database to identify all reported complications associated with each device. High-resolution photos were taken of each filter type and corresponding computed tomographic and fluoroscopic images were obtained from an institutional review board-approved IVC filter registry. A wireframe and storyboard were created, and software was developed using HTML5/CSS compliant code. The software was deployed using PhoneGap (Adobe, San Jose, CA), and the prototype was tested and refined. Twenty-three IVC filter types were identified for inclusion. Safety data from FDA MAUDE and 72 relevant peer-reviewed studies were acquired, and complication rates for each filter type were highlighted in the application. Digital photos, fluoroscopic images, and CT DICOM files were seamlessly incorporated. All data were succinctly organized electronically, and the software was successfully deployed into Android (Google, Mountain View, CA) and iOS (Apple, Cupertino, CA) platforms. A powerful electronic mobile application was successfully created to allow rapid identification of all IVC filter types and related complications. This application may be used to optimize the care of patients with IVC filters.

  • Evidence-Based Evaluation of Inferior Vena Cava Filter Complications Based on Filter Type SEMINARS IN INTERVENTIONAL RADIOLOGY Deso, S. E., Idakoji, I. A., Kuo, W. T. 2016; 33 (2): 93-100

    Abstract

    Many inferior vena cava (IVC) filter types, along with their specific risks and complications, are not recognized. The purpose of this study was to evaluate the various FDA-approved IVC filter types to determine device-specific risks, as a way to help identify patients who may benefit from ongoing follow-up versus prompt filter retrieval. An evidence-based electronic search (FDA Premarket Notification, MEDLINE, FDA MAUDE) was performed to identify all IVC filter types and device-specific complications from 1980 to 2014. Twenty-three IVC filter types (14 retrievable, 9 permanent) were identified. The devices were categorized as follows: conical (n = 14), conical with umbrella (n = 1), conical with cylindrical element (n = 2), biconical with cylindrical element (n = 2), helical (n = 1), spiral (n = 1), and complex (n = 1). Purely conical filters were associated with the highest reported risks of penetration (90-100%). Filters with cylindrical or umbrella elements were associated with the highest reported risk of IVC thrombosis (30-50%). Conical Bard filters were associated with the highest reported risks of fracture (40%). The various FDA-approved IVC filter types were evaluated for device-specific complications based on best current evidence. This information can be used to guide and optimize clinical management in patients with indwelling IVC filters.

  • Incidental Detection of Gastrointestinal Stromal Tumor by Tc-99m MDP Bone Scan CLINICAL NUCLEAR MEDICINE Shepherd, T. M., Idakoji, I. A., Pampaloni, M. H. 2012; 37 (2): 198-199

    Abstract

    This case demonstrates extraosseous 99m-technetium methylene diphosphonate (Tc-99m MDP) accumulation from a gastrointestinal stromal tumor. A 75-year-old woman underwent a temporal bone CT for conductive hearing loss that showed sclerosis in the right occipital condyle. Follow-up Tc-99m MDP bone scan for osseous metastases instead showed a mass-like extraosseous accumulation of Tc-99m MDP in the anterior left upper quadrant. Differential diagnoses included gastric cancer, lymphoma, metastatic melanoma, systemic hypercalcemia, or heterotopic mesenteric ossification. Contrast CT showed a well-circumscribed mass arising from the stomach, and subsequent pathology confirmed gastrointestinal stromal tumor. These tumors rarely can contain osteoclast-like giant cells and should be considered for extraosseous Tc-99m MDP accumulation.

  • Improving Inferior Vena Cava Filter Retrieval Rates: Impact of a Dedicated Inferior Vena Cava Filter Clinic JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY Minocha, J., Idakoji, I., Riaz, A., Karp, J., Gupta, R., Chrisman, H. B., Salem, R., Ryu, R. K., Lewandowski, R. J. 2010; 21 (12): 1847-1851

    Abstract

    To test the hypothesis that an inferior vena cava (IVC) filter clinic increases the retrieval rate of optional IVC filters.Patients who had optional IVC filters placed at the authors' institution between January 2000 and December 2008 were identified and retrospectively studied. A dedicated IVC filter clinic was established at this institution in January 2009, and there is a comprehensive database of prospectively acquired data for patients seen in the IVC filter clinic. Patients were chronologically classified into preclinic and postclinic groups. The number of optional filters retrieved and failed retrieval attempts were recorded.In the preclinic and postclinic periods, 369 and 100 optional IVC filters were placed. Median (interquartile range) number of optional filters placed per month for preclinic and postclinic periods was 3 (range 2-5) and 10 (range 6.5-10.5) (P < .001). Retrieval rates in preclinic and postclinic periods were 108 of 369 (29%) and 60 of 100 (60%) (P < .001). The median time to filter retrieval in the postclinic group was 1.5 months (95% confidence interval 1.2-1.8). The number of failed retrieval attempts in preclinic and postclinic periods was 23 of 369 (6%) and 5 of 100 (5%) (P = .823).The retrieval rate of optional IVC filters at this institution was significantly increased by the establishment of a dedicated IVC filter clinic. This retrieval increase is not related to a decrease in technical failures but more likely relates to more meticulous patient management and clinical follow-up.
