To estimate the pooled sub-distribution hazard ratio (sHR) of overt hepatic encephalopathy (OHE) and shunt dysfunction in patients with decompensated cirrhosis undergoing transjugular intrahepatic portosystemic shunt (TIPS) using dedicated stent‑grafts (DSG) versus generic stent‑grafts (GSG), and to compare their estimated 1-year event risk, relative risk (RR), and risk difference (RD). Following PRISMA guidelines, major biomedical databases were searched for retrospective studies including adults with decompensated cirrhosis undergoing TIPS with DSG or GSG. Pooled estimates for sHR, one‑year cumulative incidence, RR, and RD for OHE and shunt dysfunction were calculated. The pooled estimated 1-year event risk of OHE was 14.3
To evaluate whether splenic capsule involvement is associated with delayed re-intervention after splenic artery embolization for blunt splenic injury. This retrospective single-center study included 329 consecutive patients undergoing splenic artery embolization for blunt splenic injury (2017–2025). Capsule involvement was defined as a laceration reaching the splenic surface with capsular disruption or communication with the perisplenic space on contrast-enhanced computed tomography. The primary outcome was delayed re-intervention. Cox and Firth regression were performed, with interobserver agreement assessed by Cohen’s kappa. Delayed re-intervention occurred in 26 patients (7.9
To describe the embolization technique and clinical outcomes of uterine artery embolization (UAE) for refractory postpartum hemorrhage (PPH), and to identify variables associated with clinical failure. This retrospective cohort study included 150 consecutive patients who underwent UAE for PPH at a single tertiary center (2021–2025). Clinical failure was defined as hysterectomy or repeat embolization (≥ 2 sessions). Variables associated with clinical failure were identified by univariable logistic regression and Fisher's exact test; pre-UAE transfusion was analyzed separately to assess reverse causality. Clinical success was achieved in 140/150 patients (93.3
