JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY. Percutaneous Discal Cyst Rupture in a Professional Football Player Using Sublaminar Epidural Injection for Thecal Sac Displacement

Michael V. Friedman, MD, Andrew Park, MD , David Bumpass, MD , Jack W. Jennings, MD, PhD , Matthew J. Matava, MD

A case of percutaneous discal cyst rupture in a 25-year-old professional American football player is reported. The patient presented with a 3-day history of severe left-sided back pain. Magnetic resonance imaging examination demonstrated a discal cyst effacing the left L4-L5 lateral recess, with interposed thecal sac. A sublaminar epidural injection was performed displacing the thecal sac, exposing the discal cyst, and allowing for percutaneous perforation. The patient had complete resolution of symptoms after discal cyst rupture and was able to compete in a professional football game 3 days later. Computed tomography–guided percutaneous rupture is a therapeutic modality that may be considered for treatment of a symptomatic discal cyst.

JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY. Bard Denali Inferior Vena Cava Filter Fracture and Embolization Resulting in Cardiac Tamponade: A Device Failure Analysis

William T. Kuo, MD, Scott W. Robertson, PhD

A 46-year-old woman underwent inferior vena cava filter placement before bariatric surgery and returned within 6 months for routine removal. She complained of a 1-week history of severe chest pain, and during retrieval, two fractured filter components were identified including one arm in the right ventricle. The filter body and one fragment were successfully retrieved, but the fragment in the right ventricle was refractory to percutaneous retrieval. During open-heart surgery, the fragment was found traversing through the ventricular wall resulting in cardiac tamponade. Electron microscopic fragment analysis revealed high-cycle metal fatigue indicating the filter design failed to withstand this patient’s natural inferior vena cava biomechanical motions.

JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY. The Hangman Technique: A Modified Loop Snare Technique for the Retrieval of Inferior Vena Cava Filters with Embedded Hooks

Ramsey Al-Hakim, MD , Justin P. McWilliams, MD , William Derry, MD , Stephen T. Kee, MD

The loop snare technique is a method for inferior vena cava (IVC) filter retrieval that creates a wire loop between the filter legs; this technique may fail in cases with an embedded hook. This report describes the hangman technique, a modified loop snare technique for filter retrieval that creates a wire loop between the filter neck and IVC wall for release of embedded filter hooks. The hangman technique was attempted in 11 cases complicated by tilt (mean tilt, 13.3 degrees ± 3.9) and an embedded hook (mean dwell time, 194.5 d) with a retrieval success rate of 81.8% (9 of 11 cases) and no associated complications.

RADIOLOGY. Irreversible Electroporation: Treatment Effect Is Susceptible to Local Environment and Tissue Properties

Eliel Ben-David, MD, Muneeb Ahmed, MD, Mohammad Faroja, MD, Marwan Moussa, MD, Ayelet Wandel, MD, Jacob Sosna, MD, Liat Appelbaum, MD, Isaac Nissenbaum, BSc, S. Nahum Goldberg, MD

Irreversible electroporation (IRE) is an image-guided ablation modality that uses an electrical field without thermal energy to induce cell damage, and ultimately, cell death (1,2). Interest in IRE clinical application is increasing, especially for use in locations where thermal damage is a substantial concern, such as the pancreas (3,4) or near vital structures such as the bile ducts in the liver (2). Given that it is less sensitive to inherent tissue characteristics such as vascular heat-sink effects that limit the efficacy of thermal ablation modalities that use radiofrequency, microwave, or cryotherapy (5–7), IRE holds promise for effective treatment of tumors adjacent to blood vessels (8).

RADIOLOGY. Quantitative Elastography of Liver Fibrosis and Spleen Stiffness in Chronic Hepatitis B Carriers: Comparison of Shear-Wave Elastography and Transient Elastography with Liver Biopsy Correlation

Vivian Yee-fong Leung, PhD, Jiayun Shen, MSc, Vincent Wai-sun Wong, MD, Jill Abrigo, FRCR, Grace Lai-hung Wong, MD, Angel Mei-ling Chim, MSc, Shirley Ho-ting Chu, MSc, Anthony Wing-hung Chan, MD, Paul Cheung-lung Choi, MD, Anil T. Ahuja, MD, Henry Lik-yuen Chan, MD, Winnie Chiu-wing Chu, MD

Patients with chronic hepatitis B are at increased risk of cirrhosis. Assessment of fibrosis has important prognostic implications that guide clinical therapy (1,2). Though liver biopsy is still the reference standard for diagnosis and grading of fibrosis, it is invasive and carries risk of complications.
