Interventional radiology education: Patient experience with an educational website.

RATIONALE AND OBJECTIVES: The aim of this study was to examine the impact of an educational website on patient understanding of Interventional Radiology (IR). MATERIAL AND METHODS: An informational website with descriptions and images of 12 common IR procedures was developed with the aim of educating patients. One hundred patients referred to a large, academic institution were randomly selected to participate. Anonymous 11-question, 5-point Likert-scale assessments were administered before and after engaging with the educational website. The survey evaluated patients' understanding of IR procedures and satisfaction with the website as an educational tool. RESULTS: One hundred patients completed the pre-/post-implementation evaluations. Among matched questions, there was an increase in patient understanding of IR with mean score improvement from 2.10 to 4.57 (p < 0.001), their knowledge of common procedures from 1.74 to 4.66 (p < 0.001), and their consideration for their next procedure to be with IR from 2.24 to 4.62 (p < 0.001). Additionally, patients had an overall positive impression of the website (mean 4.80). Over 75% of patients found the descriptions and images "very helpful". CONCLUSION: This study demonstrated that website use for patient education has the potential to be effective in increasing overall patient understanding of IR and familiarity with common interventional procedures.

Long-Term Functional Outcome Following Neurosurgical Intervention for Suspected Abusive Head Trauma.

BACKGROUND: The purpose of this study was to evaluate the long-term functional and neurodevelopmental outcomes in pediatric patients who underwent neurosurgical intervention following suspected abusive head trauma (AHT). METHODS: We performed a single-center retrospective review (January 1, 2007, to December 31, 2019) of patients aged less than three years who had intracranial injury suspicious for AHT and received a neurosurgical procedure. Long-term functional outcome was measured using the Pediatric Cerebral Performance Category (PCPC), Pediatric Overall Performance Category (POPC), and the Mullen Scales of Early Learning (MSEL). RESULTS: Seventy-seven patients were identified; 53 survived to discharge and had at least one-year follow-up. To examine long-term functional outcome, PCPC at the last available visit was examined and found to be 1 or 2 (normal to mild disability) for 64% of patients and 3 or 4 (moderate to severe disability) for 36%. The last available MSEL composite score for neurodevelopmental assessment also demonstrated that 13% of patients scored in the "average" range, 17% in the "below average" range, and 70% in the "very low" range. There was no statistical difference in the last available PCPC or POPC score or the last available MSEL score for patients who received a craniotomy when compared with those who received an intracranial shunt. CONCLUSIONS: For patients with AHT who survived to discharge, functional improvements over time were noted in both patients who received craniotomy or who simply required shunt placement. These results suggest that, for patients who survive to discharge, operative management of AHT can lead to reasonable long-term functional outcomes.

Long-term Clinical Outcomes of Yttrium-90 Transarterial Radioembolization for Hepatocellular Carcinoma: A 5-Year Institutional Experience.

RATIONALE AND OBJECTIVES: To examine the clinical outcomes of yttrium-90 (Y90) transarterial radioembolization (TARE) for primary hepatocellular carcinoma (HCC) through the evaluation of a 5-year institutional experience. MATERIALS AND METHODS: This retrospective study evaluated 88 consecutive patients with primary HCC receiving Y90 TARE treatment at an academic medical center from 2017 to 2021. Disease distribution was bilobar in 60.2% of patients with an average lesion diameter of 5.0 ± 3.4 cm and Barcelona Clinic Liver Cancer stage B or C in 77% of the participants. Clinical outcomes were elucidated by examination of complications, liver function tests, biochemical response, and radiographic response. Objective response ratio (ORR) and progression-free survival (PFS) were also calculated. RESULTS: The mean administered Y90 radiation dose was 127.8 ± 20.2 Gy. No significant complications or LFT elevations occurred post-therapy. Of the 73.9% of patients with α-fetoprotein-producing tumors, 67.8% experienced a complete or partial biochemical response 1 month post-treatment. The ORR was 83.3% on 6-month imaging and PFS was 9.6 ± 8.5 months. Functional outcomes (Eastern Cooperative Oncology Group) were maintained or improved in 79.6% and 76.1% of patients by 6 months and 1 year post-treatment, respectively. The mean survival was 14.7 ± 12.1 months. At 6 months post-treatment, 77.3% of patients were downstaged to or maintained Milan criteria, which was sustained for 74.4% and 70.0% of patients 1 year and 2 years after treatment, respectively. CONCLUSION: Y90-TARE is a safe and effective therapy for primary HCC. Enduring outcomes further act as a realistic bridge to liver transplantation, with a majority of patients maintaining Milan criteria and preserving their functional status long term.

Incidence and Mortality of Pediatric Abdominal Compartment Syndrome.

INTRODUCTION: Abdominal compartment syndrome (ACS) is the presence of intra-abdominal hypertension with systemic, multiorgan effects and is associated with high mortality, yet the national incidence and mortality rates of pediatric ACS remain unknown. The aim of this study is to evaluate the incidence and mortality of pediatric ACS over a 13-year period across multiple children's hospitals and between individual children's hospitals in the United States. METHODS: We performed a retrospective cohort study on children (aged < 18 y) with ACS in the Pediatric Health Information Systems database from 2007 to 2019. We identified ACS patients by International Classification of Diseases codes in the ninth and 10th revision. The primary outcomes were incidence and mortality, which were analyzed by year, age, and hospital of admission. RESULTS: Across 49 children's hospitals, we identified 2887 children with ACS from 2007 to 2019 in the Pediatric Health Information Systems database. The overall incidence of ACS was 0.17% and the overall mortality was 48.87%. There was no significant difference in annual incidence (P = 0.12) or mortality (P = 0.39) over the study period. There was no difference in incidence across age group (P = 0.38); however, mortality in patients 0-30 d old (58.61%) was significantly higher than older age groups (P < 0.0001). The hospital-specific incidence (0.04%-0.46%) and mortality (28.57%-71.43%) varied widely. CONCLUSIONS: The annual incidence and mortality of pediatric ACS are unchanged from 2007 to 2019. ACS mortality remains high, especially in neonatal intensive care unit patients. No obvious correlation is seen between incidence rates and mortality. Differing hospital-specific incidence and mortality could suggest inconsistencies between institutions that affect pediatric ACS care, perhaps with respect to recognition and diagnosis.

Intraoperative Prediction of Long-Term Remission in Acromegaly.

BACKGROUND: The features of long-term remission in acromegaly adenomectomy are incompletely understood. An intraoperative predictor for long-term outcome would be valuable for assessing resection of growth hormone (GH)-secreting tumors in real-time. OBJECTIVE: To evaluate whether intraoperative GH measurement could predict long-term outcomes for acromegaly. METHODS: In 47 patients, peripheral blood GH levels were measured thrice intraoperatively: once before tumor dissection, once during tumor dissection, and once after tumor dissection. Long-term remission was defined by age-appropriate, normalized insulin-like growth factor-1 at most recent follow-up and a random GH less than 1.0 ng/mL. Patients were only considered to be in long-term remission without the use of postoperative medical therapy for acromegaly or radiation therapy. RESULTS: The median length of follow-up was 4.51 (range: 0.78-9.80) years. Long-term remission was achieved in 61.7% (29/47) of operations. Like previous studies, cavernous sinus invasion (odds ratio [OR]: 0.060; 95% CI: 0.014-0.260; P value < .01), suprasellar extension (OR: 0.191; 95% CI: 0.053-0.681; P value<.01), and tumor size greater than 1 cm (OR: 0.177; 95% CI: 0.003-0.917; P value = .03) were associated with not being in long-term remission. The minimum GH measured intraoperatively predicted long-term outcome (area under the curve: 0.7107; 95% CI: 0.537-0.884; P value < .01). The odds ratio of remission in patients with the lowest quartile minimum intraoperative GH compared with patients with the highest quartile minimum intraoperative GH was 27.0 (95% CI: 2.343-311.171; P value < .01). CONCLUSION: Minimum intraoperative GH may predict long-term outcome for acromegaly, which in principle could provide the pituitary neurosurgeon with real-time feedback and inform intraoperative decision making.

Noninvasive Approaches for Anxiety Reduction During Interventional Radiology Procedures.

Periprocedural anxiety is a major cause of morbidity, particularly for interventional radiology procedures that often depend on conscious sedation. Management of anxiety and pain during image-guided procedures has traditionally relied on pharmacologic agents such as benzodiazepines and opioids. Although generally safe, use of these medications risks adverse events, and newer noninvasive, nonpharmacologic techniques have evolved to address patient needs. In this review, we explore the roles of hypnosis, structured empathic attention, anodyne imagery, music, video glasses, and mobile applications in reducing procedural anxiety and pain with the goal of improving patient satisfaction, operational efficiency, and clinical outcomes.
