Background: Osteoid osteoma (OO) is a benign osteogenic tumor that causes severe pain despite its small size. Minimally invasive image-guided thermal ablation has replaced surgery as the treatment of choice. While radiofrequency ablation (RFA) is considered the gold standard, microwave ablation (MWA) offers faster and more homogeneous heating, though comparative evidence remains limited. Methods: We retrospectively analyzed 53 patients with OO treated with RFA (n = 27) or MWA (n = 26) between 2014 and 2023. All procedures were CT-guided. Technical success, clinical success, recurrence, complications, and prognostic factors—including the nidus diameter and eccentricity index—were evaluated over a minimum 24-month follow-up period. Results: Technical success was achieved in all cases. Overall clinical success was 94.3% (96.2% MWA vs. 92.6% RFA, p = 1.000). Two recurrences (4%) occurred, unrelated to device type. One major complication (1.9%, third-degree skin burn after MWA) was noted. Median nidus diameter was 7 mm; lesions ≥10 mm were significantly linked to failure (p = 0.009). Logistic regression identified nidus size as the strongest outcome predictor, with the eccentricity index showing a borderline effect. Conclusions: Both RFA and MWA are safe and effective for OO, with comparable outcomes and low recurrence rates. Treatment selection should prioritize lesion-specific factors—particularly nidus size ≥ 10 mm and geometry—rather than device type. Lesion size (≥10 mm) and geometry—not ablation modality—were the principal determinants of treatment success. Individualized modality selection based on these features may optimize outcomes.

Purpose: This study aimed to evaluate the efficacy and safety of the Angio-Seal™ VIP vascular closure device (VCD) in achieving hemostasis following percutaneous transhepatic portal venous interventions. Methods: This retrospective study evaluated 20 patients (mean age: 52.85 ± 16.18 years; 80% male) who underwent percutaneous transhepatic portal vein interventions followed by tract closure with the Angio-Seal™ device between January 2016 and September 2024. Procedural data, pre- and post-procedural hemoglobin and hematocrit levels, and complications were analyzed. Technical success was defined as the successful deployment of the device with immediate hemostasis and no evidence of bleeding on post-procedural imaging. Results: Technical success, as defined in this study, was achieved in all 20 procedures (100%). The mean hemoglobin level declined from 11.91 ± 2.01 g/dL to 11.09 ± 2.19 g/dL (p < 0.001), and the mean hematocrit level decreased from 36.18 ± 6.03% to 32.98 ± 5.80% (p = 0.001). A hemoglobin drop ≥2 g/dL occurred in two patients (10%) and a hematocrit drop ≥4% in six patients (30%); none were associated with imaging or clinical evidence of hemorrhage. No major complications were observed. Minor complications, including localized pain managed with analgesics, occurred in five patients (25%). Follow-up imaging confirmed the absence of hemoperitoneum or device-related failure. Conclusions: Angio-Seal™ is a technically feasible, safe, and effective option for tract closure following percutaneous transhepatic portal vein access. This single-device approach may offer a cost-effective alternative to traditional embolization techniques. However, more extensive prospective studies are required to validate these findings.

Background/Objectives: High-risk coronary plaques (HRP), identified through coronary CT angiography (CCTA), are closely linked to cardiovascular events. Nutritional status and systemic inflammation may play a critical role in the development of HRP. The Naples Prognostic Score (NPS), which integrates markers of nutritional status and systemic inflammation, has emerged as a potential predictor of outcomes in various cardiovascular conditions. This study aimed to investigate the association between NPS and HRP as assessed by CCTA. Methods: A retrospective analysis was performed on 753 patients with chronic coronary syndrome (CCS) who underwent CCTA. The patients were categorized into two groups: those with high-risk plaques (HRP present), and those without (HRP absent). Additionally, they were further stratified based on their NPS. Univariable and multivariable logistic regression analyses were conducted to identify the most relevant clinical factors and the role of NPS in relation to HRP and the need for revascularization. Results: The study population had a mean age of 56.9 ± 10.7 years, with 40% being female. The NPS was significantly higher in the HRP-present group compared to the HRP-absent group (p = 0.001). Stratification by NPS groups revealed that higher NPS groups were associated with increased coronary artery calcification scores (CAC) and revascularization rates (p < 0.001 and p = 0.003, respectively). Multivariable regression analysis demonstrated a significant association between NPS and HRP (OR = 1.228, 95% CI: 1.013–1.489, p = 0.036). Conclusions: The NPS is independently associated with the presence of high-risk coronary plaques in patients with chronic coronary syndrome. NPS may serve as a complementary risk stratification tool by reflecting systemic inflammation and nutritional status. Further prospective studies are needed to validate its prognostic value.

Background: Thoracic kyphosis has been increasingly associated with altered intra-abdominal and diaphragmatic dynamics, potentially contributing to gastroesophageal reflux disease (GERD) and hiatal hernia (HH). While previous studies have shown a relationship between spinal deformities and GERD symptoms, these findings have been largely observational, with few morphometric analyses. No prior study has directly quantified the relationship between thoracic curvature and hiatal surface area (HSA) using standardized computed tomography (CT)-based methods. Furthermore, existing studies have typically focused on patients with visible hernias, limiting understanding of early, subclinical anatomical changes. This study addresses this gap by evaluating whether thoracic kyphosis is associated with measurable hiatal enlargement, even in the absence of overt HH. Methods: In this retrospective, single-center study, 100 adult patients (50 with thoracic kyphosis, defined as a Cobb angle of ≥50° and 50 age- and sex-matched controls) underwent multidetector CT (MDCT). Hiatal surface area (HSA) was measured on a standardized oblique axial plane aligned with the diaphragmatic crura. Correlation and multivariable regression analyses were performed to assess relationships between Cobb angle and HSA. Results: The kyphosis group showed significantly larger HSA than controls (5.14 ± 1.31 cm² vs. 3.59 ± 0.74 cm²; p < 0.001). A moderate positive correlation was found between Cobb angle and HSA (r = 0.336, p = 0.017). Multivariable analysis identified the Cobb angle as an independent predictor of HSA (β = 0.028; p = 0.017), while age and sex were not significant predictors. No overt herniation was present in any subject. Conclusions: This is the first CT-based morphometric study to demonstrate that thoracic kyphosis is associated with hiatal enlargement, even in the absence of overt herniation. These findings support the hypothesis that postural spinal deformities may predispose individuals to GERD by structurally remodeling the diaphragmatic hiatus.

Background/objectives: Silent cerebral infarction (SCI) is a common but underrecognized condition characterized by asymptomatic cerebral lesions detected via magnetic resonance imaging (MRI). While traditional vascular risk factors contribute to its pathogenesis, novel biomarkers may enhance risk stratification. The serum albumin to creatinine ratio (sACR) reflects nutritional status and renal function—two factors closely linked to vascular health. This study aimed to investigate the association between sACR and the presence of SCI, as well as its potential prognostic value for long-term outcomes.Methods: We retrospectively analyzed 272 consecutive patients who visited the neurology outpatient clinic and underwent brain MRI for any reason, provided they met the study’s inclusion criteria. Patients with a history of cerebrovascular disease or other exclusion criteria were not included. Baseline demographic and laboratory data, including sACR, were collected. SCI was identified using standardized imaging criteria. Adverse outcomes, including cerebrovascular events and atrial fibrillation/flutter, were assessed over a median follow-up period of 37 months.Results: Patients with SCI had significantly 24 lower sACR levels compared to those without SCI. In multivariable logistic regression analysis, each 1-point decrease in sACR was independently associated with a 1.790-fold increase in the odds of SCI (95% CI: 1.384–2.315, p < 0.001). ROC curve analysis yielded a modest discriminatory ability for sACR in predicting SCI (AUC = 0.674; cut-off: 5.13). Kaplan–Meier survival analysis showed a trend toward higher long-term outcome in the low sACR group, but this did not reach statistical significance (log-rank p = 0.088).Conclusion: Lower sACR levels are independently associated with the presence of SCI. While the association between sACR and long-term outcomes requires further investigation, sACR may serve as a cost-effective biomarker for assessing subclinical cerebrovascular risk. Future prospective studies are needed to validate these findings and clarify the clinical utility of sACR-guided risk stratification.
