Obesity increases the risk of cardiovascular diseases (CVD), however, whether adipose tissue relates to dyslipidemia, and consequently to cardiovascular events remains unknown. Thus, we investigated the association of adipose tissue with circulating lipoproteins and triglycerides (TG) in subjects without CVD. 384 participants from the KORA-MRI study (mean age 56.2 ± 9.2 years; 41.9% female) underwent whole-body 3T-MRI. Visceral (VAT) and subcutaneous adipose tissue (SAT) derived from T1-DIXON-sequence using a semi-automatic algorithm. Total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and TG were measured. Linear regression was applied to examine the relationships between adipose tissue, circulating lipoproteins, and TG, adjusting for risk factors. VAT was associated with total cholesterol (per SD increase) (ß = 0.39, p < 0.001). Total adipose tissue (TAT) and VAT were inversely associated with HDL (ß = −0.09, p = 0.009; ß = −0.14, p < 0.001), and positively associated with LDL (ß = 0.32, p < 0.001; ß = 0.37, p < 0.001). All adipose tissues were associated with TG (ß = 0.20, p < 0.001; ß = 0.27, p < 0.001; ß = 0.11, p = 0.004). Stratified analysis by sex and body mass index (BMI) was confirmatory in women and in individuals with BMI < 30. Our results suggest that adipose tissue plays an important role in increasing CVD risk independent of BMI, whereas gender imbalance may be explained by accurate characterization and quantification of adipose tissue.

Background: In magnetic resonance imaging (MRI), the comparability of gated and non-gated measurements of the left atrial (LA) area and function and their association with cardiovascular risk factors have not been firmly established. Methods: 3-Tesla MRIs were performed on 400 subjects enrolled in the KORA (Cooperative Health Research in the Augsburg Region) MRI study. The LA maximum and minimum sizes were segmented in gated CINE four-chamber sequences (LA_max and LA_min) and non-gated T1 VIBE-Dixon (NGLA). The area-based LA function was defined as LAaf = (LA_max − LA_min)/LA_max. Inter-and intra-reader reliability tests were performed (n = 31). Linear regression analyses were conducted to link LA size and function with cardiovascular risk factors. Results: Data from 378 subjects were included in the analysis (mean age: 56.3 years, 57.7 % male). The measurements were highly reproducible (all intraclass correlation coefficients ≥ 0.98). The average LA_max was 19.6 ± 4.5 cm², LA_min 11.9 ± 3.5 cm², NGLA 16.8 ± 4 cm² and LAaf 40 ± 9%. In regression analysis, hypertension was significantly associated with larger gated LA_max (β = 1.30), LA_min (β = 1.07), and non-gated NGLA (β = 0.94, all p ≤ 0.037). Increasing age was inversely associated with LAaf (β = −1.93, p < 0.001). Conclusion: LA enlargement, as measured in gated and non-gated CMR is associated with hypertension, while the area-based LA function decreases with age.

Portal vein arterialization is a rarely used, temporary surgical salvage solution to prevent biliary and hepatic ischemia and necrosis in acute liver de-arterialization. However, it can induce portal hypertension, causing increased morbidity and mortality. We report the case of a 5-year-old girl with portal hypertension and right ventricle volume overload following the creation of an iliacoportal shunt graft for portal vein arterialization due to vessel-adhering neuroblastoma. Partial shunt graft closure was accomplished by placing a stent graft in an hourglass configuration via the right femoral artery using two slender-sheaths in a line with the second more distal than the first. Subsequently, the patient’s symptoms of right ventricle volume overload and portal hypertension decreased. In conclusion, endovascular reduction of elevated portal blood flow after portal vein arterialization is feasible, even in pediatric patients. Graphical abstract

A 68-year-old male with liver cirrhosis presented with dizziness and dyspnea two days after endoscopic Histoacryl occlusion of gastric varicses. Imaging revealed a large endovascular embolization of Histoacryl glue, spanning from porto-caval collaterals via the inferior vena cava to the right atrium, partially occluding right atrial inflow. This case report describes the successful removal of this large net-like mass of Histoacryl glue using thrombectomy devices from the inferior vena cava and the right atrium. Postprocedure imaging showed near-complete clearance with residual fragments in the superior mesenteric vein and small emboli in the pulmonary arteries. The patient was discharged in stable condition. Histoacryl glue can cause severe complications if embolized. This case highlights the potential of advanced thrombectomy devices for managing embolic complications from endovascular treatments.

In multimorbid patients with end-stage kidney disease awaiting renal transplantation, thromboembolic events may significantly complicate and delay the transplantation process. In the period bridging the transplant, hemodialysis is often carried out using a hemodialysis catheter, which is susceptible to complications. We report a case of a 43-year-old woman with Anti-Neutrophil Cytoplasmic Antibodies negative vasculitis, awaiting an ABO-incompatible kidney transplant, and whose hemodialysis catheter required removal due to improper functioning. Computed tomography revealed the presence of a persistent dislodged fragment of the hemodialysis catheter, accompanied by thrombus formation in the superior vena cava and internal jugular vein. We successfully performed endovascular, minimally invasive thrombectomy via right basilic vein access, removing thrombus and dislodged catheter fragments from the superior vena cava. We then reimplanted a new tunneled hemodialysis catheter. This case underscores the feasibility and clinical benefits of targeted interventional techniques in managing complex complications in patients with end-stage kidney disease.
