Society of Interventional Radiology, March 22-27

The Society of Interventional Radiology's 39th Annual Meeting

The annual meeting of the Society of Interventional Radiology was held from March 22 to 27 in San Diego and attracted more than 5,000 participants from around the world, including scientists, allied health professionals, and others interested in interventional radiology. The conference highlighted recent advances in disease management and minimally invasive, image-guided therapeutic interventions, with nearly 400 scientific presentations and posters covering the latest trends in interventional radiology research.

In one study, David Waldman, M.D., Ph.D., of the University of Rochester Medical Center in New York, and colleagues found that individuals who underwent an interventional procedure had lower anxiety following the procedure when they were distracted by wearing video goggles and viewing calming content.

"We can reduce a patient's anxiety level during an interventional radiology procedure by having them view calming video content. Furthermore, the video goggles did not interfere with the procedure or the physician's concentration," said Waldman. "We plan on rolling this out across all of our interventional radiology sites. We will collect data using a multi-center patient population. We will more critically assess if we might be able to lower the moderate sedation needs of our patients."

In another study, João Martins Pisco, M.D., Ph.D., of Saint Louis Hospital in Lisbon, Portugal, and colleagues found that minimally invasive prostate artery embolization (PAE) was effective in reducing frequent urination and other symptoms associated with an enlarged prostate. In addition, as compared to surgery, PAE was associated with similar outcomes and enabled patients to leave the hospital three to six hours after treatment with immediate symptom relief. PAE was not associated with an increased risk of urinary incontinence or sexual dysfunction and not associated with any major complications.

"It is a simple procedure with good results. It will be the future standard treatment," said Pisco.

One author disclosed a financial relationship with Cook Medical.

Abstract No. 108

Robert Lewandowski, M.D., of the Northwestern University Feinberg School of Medicine in Chicago, and colleagues evaluated the efficacy and safety of radioembolization in 75 patients with metastatic breast cancer that had spread to the liver and with significant disease burden that progressed despite many different chemotherapy regimens. The investigators found that radioembolization was safe (performed on an outpatient basis) and provided disease stabilization in 98.5 percent of patients treated. Those patients who had normal liver functions and less than 25 percent of their liver burdened by cancer had the best prognosis.

"Radioembolization is a minimally invasive interventional radiology procedure that is safe, maintains quality of life, and provides anti-tumor control in patients with metastatic breast cancer to the liver. This is an emerging therapy in patients with literally no other treatment options," said Lewandowski. "Future studies will be designed to evaluate the effectiveness of this therapy earlier in the course of these patients' disease. Further, there is much interest in combining currently administered systemic chemotherapy agents (e.g., capecitabine) with radioembolization, with the radiosensitizing ability of the chemotherapy potentially having a synergistic impact on the local radiation."

Abstract No. 193

Sandeep Bagla, M.D., of Inova Alexandria Hospital in Virginia, and colleagues found that a minimally invasive treatment option, percutaneous microwave ablation, is a safe and reasonably effective method for treating lung tumors.

"This research confirms what earlier investigations on microwave ablation have shown. Interventional radiologists may offer a unique minimally invasive therapy to treat the many patients who have limited options for surgery or spread of tumors to the lung," said Bagla. "Future studies may be performed to prospectively evaluate microwave ablation versus other therapies such as radiation or surgery."

SIR: Kiva System Noninferior to Balloon Kyphoplasty

TUESDAY, March 25, 2014 (HealthDay News) -- The Kiva system, a novel implant for vertebral body augmentation, is non-inferior to balloon kyphoplasty for the treatment of vertebral compression fractures (VCFs), according to a study presented at the annual meeting of the Society of Interventional Radiology, held from March 22 to 27 in San Diego.
