Abstract Background Endovascular treatment of vascular pathologies through the transradial approach has been increasingly used and has demonstrated a low rate of complications. Objective To report our initial experience in the endovascular treatment of cerebrovascular diseases with the transradial approach and to determine its safety and feasibility. Methods Consecutive patients who underwent the transradial approach for endovascular treatment of aneurysms and vascular malformations were reviewed at a single institution. Technical success, fluoroscopy time, and access-related complications were analyzed. Results Eight patients underwent endovascular treatment with the transradial approach. One arteriovenous fistula, one superficial temporal artery aneurysm, three arteriovenous malformations, and four aneurysms were treated successfully. The radial artery was successfully approached and a 6-F sheath was used in all the cases. Navigation of guiding catheters (5 and 6 F) was done without complications. The most commonly approached artery was the right internal carotid artery, followed by the right vertebral artery. Postoperative vasospasm was identified in three patients. Mean fluoroscopy time was 34.7 minutes. Conversion to transfemoral approach was not required. No postoperative complications were reported. Conclusions In our initial experience, the transradial approach is a safe and feasible alternative for the endovascular treatment of cerebrovascular pathologies.

Abstract Background: The severity of the cardiac complications resulting from Kawasaki disease (KD) appears to be directly correlated to the magnitude of the coronary artery aneurysm (CAA). However, there remains some unclear about the risk factors for medium-large CAA identified after acute KD.Methods: We analyzed 90 patients diagnosed with CAA in KD hospitalized from January 2013 through August 2021. Patients were stratified based on the coronary artery z-score adjusted for body surface area as the medium-large CAA group and small-sized CAA group. The association of baseline characteristics was investigated within the groups. Multivariable logistic regression analyses were performed to evaluate potential risk factors associated with medium-large CAA development.Results: In total, 353 pediatric cases with KD were investigated during the study period, of whom 90 (25.5%) presented with CAA, including medium-large CAA in 20 patients (5.7%) after acute KD. The medium-large CAA group showed significantly higher Harada risk scores, the incidence of thrombosis, serum globulin concentration values, proportions of C-reactive protein > 40 mg/L, proportions of albumin < 35 g/L, and lower values of albumin-to-globulin ratio (A/G ratio) than those in the small-sized CAA group (P < 0.05). Medium-large CAA was significantly associated with the A/G ratio (odds ratio, 3.503; 95% confidence interval [CI]: 1.068–11.492). The area under the receiver operating characteristic curve was 0.684 (95% CI: 0.558–0.810), and the cutoff point of 1.35 showed a sensitivity and specificity for predicting medium-large CAA of 80% and 59%, respectively.Conclusions: A lower A/G ratio independently predicts medium-large CAA in patients with KD. Medium-large CAA is associated with greater odds of developing thrombosis. Thus, close monitoring with routine echocardiography is recommended.

Abstract Background Cases of giant coronary artery aneurysms associated with coronary fistula are rarely reported, and they present with various symptoms, including coronary steal syndrome. We report an uncommon case of an asymptomatic giant coronary fistula aneurysm presenting as a progressing left-sided mediastinal mass that has been tracked for years. Case summary A 67-year-old healthy asymptomatic woman was referred to our hospital because of an abnormal shadow on her chest radiography revealing a left-sided mediastinal mass that had progressed in size over the past 4 years. Computed tomography revealed mass progression from 4 cm to 5 cm in diameter within 2 years. Coronary computed tomography and coronary angiography identified a giant coronary artery aneurysm in a coronary fistula originating in the left anterior descending artery and draining into the main pulmonary artery. Transthoracic Doppler echocardiography revealed a unique systolic-dominant flow. She underwent coronary artery aneurysmectomy and fistula ligation. The patient has been in good health without any events for 10 months since her discharge. Discussion A giant coronary artery aneurysm in a coronary fistula can present as an asymptomatic left-sided mediastinal mass that has progressed in size for years in older adults. Echocardiography can provide clues of the steal phenomenon in coronary artery fistula. A close investigation of mediastinal abnormalities can facilitate the detection of coronary aneurysms.

Abstract Objective The aims of this study were to characterize the evolution of routine blood values within the first 10 days of illness and coronary artery outcome in infants < 8 months with Kawasaki disease (KD) and to identify risk factors for coronary artery aneurysm (CAA). Methods Laboratory data, clinical features and coronary artery outcomes from 78 infants < 8 months old and 86 patients between 8 months and 7 years old were retrospectively analyzed. Logistic regression analysis was conducted to evaluate the potential risk factors for CAA. Results Infants < 8 months old were more likely to present with incomplete KD (37.2% vs 4.7%, P < 0.001), erythema and induration at the BCG inoculation site (24.4% vs 3.5%, P < 0.001) and CAA (47.4% vs 15.1%, P < 0.001) even with timely diagnosis and treatment with intravenous immunoglobulin (IVIG) compared with patients ≥8 months old. Clinical feature related to diagnostic criteria for KD including bilateral conjunctival injection, oral changes, unilateral cervical lymphadenopathy and extremity changes were less common in the younger group. During the acute phase, the percentage neutrophils and neutrophil to lymphocyte ratio [NLR] peaked on median illness day 3, followed by white blood cell (WBC) and CRP on median illness day 4, hemoglobin on median illness day 7 and platelet count on median illness day 9. CAA occurred on median illness day 6 and regressed on median illness day 28. Multivariate logistic regression analysis revealed that the peak percentage neutrophils (odds ratio [OR] per 0.1: 1.597, 95% confidence interval [CI]: 1.041–2.452, P = 0.032) and the peak platelet count (OR per 10 × 109/L: 1.029, 95% CI: 1.004–1.055, P = 0.024) were independent risk factors for CAA. Hemoglobin on the 5th day was associated with persistent CAA at 1 year after KD onset. Conclusion Factors associated with CAA include a high peak percentage neutrophils, increased peak platelet count, and reduced hemoglobin within 4–6 days during the acute phase of KD. Therefore, this population should receive primary therapy with IVIG and adjunctive anti-inflammatory medications.
