Interventional Radiology operated percutaneous cholecystoscopy with ultrasonic lithotripsy and stone basket retrieval a treatment for symptomatic cholelithiasis in non operative candidates
Journal of Medical Imaging and Radiation Oncology, 2019Co-Authors: Dustin G Roberts, Adam N Plotnik, Jeffrey Fb Chick, Ravi N SrinivasaAbstract:Interventional Radiology-operated percutaneous endoscopy has seen a recent resurgence with potential to return to the scope of Interventional Radiology practice. Endoscopy adds a new dimension to the Interventional Radiology armamentarium by offering a unique opportunity to diagnose and treat conditions under direct visualization with improved maneuverability. Cholecystoscopy (gallbladder endoscopy), as a method for percutaneous removal of gallstones, is an effective treatment option in patients with symptomatic cholelithiasis who are poor candidates for surgical cholecystectomy. This article presents a case of Interventional Radiology-operated cholecystoscopy using ultrasonic lithotripsy and stone basket retrieval with an emphasis on the equipment, technique, and peri-procedural management essential to the procedure, as well as a review of the literature.

Interventional Radiology operated endoscopy using the lithovue disposable endoscope approach technical success clinical outcomes and complications
Indian Journal of Radiology and Imaging, 2018Co-Authors: Nishant Patel, Jeffrey Forris Beecham Chick, Joseph J Gemmete, Rudra Pampati, Evan Johnson, Ravi N SrinivasaAbstract:Purpose: To report the approach, technical success, clinical outcomes, and complications of Interventional Radiology-operated endoscopy using the LithoVue disposable endoscope. Materials and Methods: 12 patients, 6 (50%) males and 6 (50%) females, underwent Interventional Radiology-operated endoscopy using the LithoVue disposable endoscope between April 2016 and August 2017. Presenting complaint, reason for endoscopic evaluation, technical success, clinical success, procedure time, fluoroscopy time, hospital length of stay, and complications were recorded. Results: Interventional Radiology-operated endoscopy using the LithoVue disposable endoscope was used in 8 (67%) biliary, 2 (16.5%) urologic, and 2 (16.5%) gastrointestinal procedures. Five (42%) patients required endoscopy to locate an ostium that could not be cannulated under fluoroscopy. Five (42%) patients had a biliary-enteric anastomosis with postoperative anatomy of the bowel which precluded endoscopic retrograde cholangiopancreatography and underwent endoscopy for removal of calculi. One (8%) patient underwent treatment of a stricture and one (8%) underwent biopsy. Technical success was 92% (11/12). Clinical success was 83% (10/12). Two complications, a perinephric hematoma and sepsis, occurred. Conclusion: Disposable endoscopes, including the LithoVue, may be used in a variety of procedures to improve patient care and limit fluoroscopy.

Interventional Radiology-Operated Endoscopy as an Adjunct to Image-Guided Interventions
Current problems in diagnostic radiology, 2018Co-Authors: Rajiv N. Srinivasa, Jeffrey Forris Beecham Chick, Kyle J. Cooper, Ravi N SrinivasaAbstract:ABSTRACT Purpose Interventional Radiology-operated endoscopy is an underused technique, which may have a significant impact on the ability to treat patients with a variety of conditions. The purpose of this article is to discuss the setup, equipment, and potential clinical uses of Interventional Radiology-operated endoscopy. Methods A number of new and innovative interventions may be performed in the biliary, genitourinary, and gastrointestinal systems through percutaneous access that Interventional radiologists already create. When used in combination, endoscopy adds an entirely new dimension to the fluoroscopic-guided procedures of which Interventional radiologists are accustomed. Results Interventional radiologists are in a unique position to implement endoscopy into routine practice given the manual dexterity and hand-eye coordination already required to perform other image-guided interventions. Conclusion Although other specialists traditionally have performed endoscopic interventions and local politics often dictate referral patterns, a collaborative relationship among these specialists and Interventional Radiology will allow for improved patient care. A concerted effort is needed by Interventional radiologists to learn the techniques and equipment required to successfully incorporate endoscopy into practice.

American Journal of Roentgenology, 2013Co-Authors: Koichi Chida, Yuji Kaga, Yoshihiro Haga, Nozomi Kataoka, Eriko Kumasaka, Taiichiro Meguro, Masayuki ZuguchiAbstract:OBJECTIVE. Interventional Radiology tends to involve long procedures (i.e., long fluoroscopic times). Therefore, radiation protection for Interventional Radiology staff is an important issue. This study describes the occupational radiation dose for Interventional Radiology staff, especially nurses, to clarify the present annual dose level for Interventional Radiology nurses. MATERIALS AND METHODS. We compared the annual occupational dose (effective dose and dose equivalent) among Interventional Radiology staff in a hospital where 6606 catheterization procedures are performed annually. The annual occupational doses of 18 physicians, seven nurses, and eight radiologic technologists were recorded using two monitoring badges, one worn over and one under their lead aprons. RESULTS. The annual mean ± SD effective dose (range) to the physicians, nurses, and radiologic technologists using two badges was 3.00 ± 1.50 (0.84–6.17), 1.34 ± 0.55 (0.70–2.20), and 0.60 ± 0.48 (0.02–1.43) mSv/y, respectively. Similarly, t...

radiation dose of Interventional Radiology system using a flat panel detector
American Journal of Roentgenology, 2009Co-Authors: Koichi Chida, Yohei Inaba, Haruo Saito, Tadashi Ishibashi, Shoki Takahashi, Masahiro Kohzuki, Masayuki ZuguchiAbstract:OBJECTIVE. Currently, cardiac Interventional Radiology equipment has tended toward using flat-panel detectors (FPDs) instead of image intensifiers (IIs) because FPDs offer better imaging performance. However, the radiation dose from an FPD in cardiac Interventional Radiology is not clear. The purpose of our study was to measure the radiation doses during cineangiography and fluoroscopy of many cardiac Radiology systems that use FPDs or IIs, in clinical settings.MATERIALS AND METHODS. This study examined 20 Radiology systems in 15 cardiac catheterization laboratories (11 used FPD and nine used II). The entrance surface doses with digital cineangiography and fluoroscopy were compared for the 20 systems using acrylic plates (20-cm thick) and a skin dose monitor.RESULTS. For fluoroscopy, the average entrance surface doses of the 20-cm-thick acrylic plates were identical for FPD (average ± SD, 16.63 ± 7.89 mGy/min; range, 5.7–26.4 mGy/min; maximum/minimum, 4.63) and II (17.81 ± 12.52 mGy/min; range, 6.5–42.2 m...

requirements for training in Interventional Radiology
Journal of Vascular and Interventional Radiology, 2013Co-Authors: Daniel Siragusa, John A. Kaufman, John F Cardella, Robert A Hieb, Hyun Soo Kim, Boris Nikolic, Sanjay Misra, Scott A Resnick, Wael E Saad, Geogy VatakencherryAbstract:PREAMBLE In recent years, the Society of Interventional Radiology (SIR) has become aware of a growing heterogeneity in the learning experiences of Radiology trainees (residents and fellows) as it pertains to the subject of Interventional Radiology (IR). Unfortunately, the Accreditation Council for Graduate Medical Education (ACGME) program requirements are somewhat vague as to what constitutes adequate training in this field. Therefore, a task force was created to create guidelines for training in the field of IR. Task force members included physicians who practice in academic and private-practice settings. Also, the task force contained a cross-section of thought leaders in the various clinical realms of IR (peripheral arterial disease, Interventional oncology, venous disease, Interventional neuroRadiology, and renal insufficiency). Many members are current or past program directors of diagnostic Radiology (DR) residencies or IR fellowships. The guidelines put forth in this document are intended for the training of Radiology residents and IR fellows in the knowledge base and technical skills related to minimally invasive Interventional procedures. As part of this education, trainees must gain an appropriate depth of understanding of the disease states being treated and their clinical management to allow for optimal clinical outcomes. It is intended that program directors in DR residencies and program directors in vascular and IR (VIR) fellowships will use this document as a basis for the creation of program-specific curricula and goals and objectives documents for trainees. In addition, this document is intended for reference by Radiology chairs, designated institutional officials, and deans so they may allocate appropriate resources to training programs to meet these training requirements. Finally, although training paradigms differ around the world, it is hoped that these guidelines will also be helpful in the creation of educational curricula for international IR programs as well. SIR recognizes that the multiple levels of trainees covered by this document will require differing experiences to meet their differing needs. For example, the DR trainee who is pursuing a career in a general Radiology or in a diagnostic imaging subspecialty will not require the same training as a resident planning to enter into a VIR fellowship. Therefore, four separate sets of training requirements will be set forth in this document:

The Interventional Radiology business plan.
Journal of vascular and interventional radiology : JVIR, 2012Co-Authors: Michael V Beheshti, Mary E. Meek, John A. KaufmanAbstract:Strategic planning and business planning are processes commonly employed by organizations that exist in competitive environments. Although it is difficult to prove a causal relationship between formal strategic/business planning and positive organizational performance, there is broad agreement that formal strategic and business plans are components of successful organizations. The various elements of strategic plans and business plans are not common in the vernacular of practicing physicians. As health care becomes more competitive, familiarity with these tools may grow in importance. Herein we provide an overview of formal strategic and business planning, and offer a roadmap for an Interventional Radiology-specific plan that may be useful for organizations confronting competitive and financial threats.

patterns of anesthesia and nursing care for Interventional Radiology procedures a national survey of physician practices and preferences
Radiology, 1997Co-Authors: Peter R Mueller, Keith H Wittenberg, John A. KaufmanAbstract:PURPOSE: Through a survey of Interventional radiologists, to document patterns of conscious sedation, nursing assistance, and care before and after the intervention and to compare demographics and different Interventional Radiology practices. MATERIALS AND METHODS: The survey was sent to the 1,713 members of the Society of Cardiovascular and Interventional Radiology. The levels of sedation were categorized according to the following grading scale commonly employed by anesthesiologists: awake/alert, drowsy/arousable, asleep/arousable, deep sedation, and general anesthesia. The drugs used for sedation were recorded. The procedures were categorized as diagnostic vascular or visceral or therapeutic vascular or visceral. Data were available for most standard vascular and visceral procedures. RESULTS: Six hundred thirty-four (37%) Interventional radiologists responded, and 500,000 procedures were analyzed. Most (90%) therapeutic procedures employed the drowsy/arousable level of sedation. Eighty-seven percent of...
