Background: and Purpose Vertebrobasilar fusiform aneurysms (VBFAs) carry substantial morbidity and mortality, but optimal management for unruptured VBFAs remains unclear. We compared the safety and efficacy of conservative management (CM), stent-assisted coiling (SAC), and flow diverters (FDs) in patients with unruptured VBFAs, focusing on long-term prognosis. Methods: This study included data from a nationwide Chinese cohort of patients with vertebrobasilar dissecting aneurysms. Inverse probability of treatment weighting (IPTW) balanced confounders across groups. The primary outcome was poor prognosis (modified Rankin Scale score >2). Secondary outcomes included aneurysm rupture, ischemic stroke, compression symptoms, and VBFA-related deaths. Logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup and sensitivity analyses were performed. Results: Among 1,115 patients with unruptured VBFAs, 838 (median age, 54 years; 655 men) were included. After IPTW, baseline characteristics were balanced. Median follow-up was 54 months. FD was associated with a lower risk of poor prognosis than CM (OR, 0.48 [95% CI, 0.30 to 0.77]; p=0.002), with no difference between CM and SAC. FD also reduced aneurysm rupture (OR, 0.20 [95% CI, 0.07 to 0.60]; p=0.004) and compression symptoms (OR, 0.30 [95% CI, 0.13 to 0.68]; p=0.004) versus CM. Time-to-event analyses further revealed significant differences in vertebral artery lesions and Type I–II VBFAs, whereas no significant differences were observed in basilar or vertebrobasilar junction lesions or in Type III–IV VBFAs. Conclusions Compared with CM, FD was associated with improved long-term outcomes in unruptured VBFAs, particularly in vertebral artery lesions and Type I–II VBFAs, although residual confounding cannot be excluded.

Objective To investigate the effect of medicinal charcoal tablets combined with blood purification therapy on on renal function, inflammatory mediators, oxygenation index and intestinal barrier function in patients postoperative severe abdominal infection.Methods 65 cases with severe abdominal infection from the hospital were selected and randomly divided into control group (32 cases) and experiment group (33 cases) by random digital table method.The control group were treated by clinical routine therapy and experiment group were treated on the basis of control group with medicinal charcoal tablets combined with blood purification therapy.The renal function, inflammatory mediators, oxygenation index, intestinal barrier function and efficacy were tested.ResuIts Compared with control group after treatment, the renal function of serum creatinine (Scr), blood urea nitrogen (BUM), uric acid (UA) levels were lower (P<0.05), the inflammatory mediators of tumor necrosis factor α(TNF-α), interleukin-6 (IL-6) and interleukin-8 (IL-8) levels were lower (P<0.05), the oxygenation index (OI) was higher(P<0.05), the intestinal barrier function indicators of plasma diamine oxidase (DAO) and endotoxin of lipopolysaccharide (LPS) were lower (P<0.05), the total efficiency were higher (χ2 =3.91, P<0.05) in experimental group.ConcIusion The medicinal charcoal tablets combined with blood purification could effectively improve renal function, reduce inflammatory mediators levels, improve intestinal barrier function, and increase oxygenation index in patients with severe abdominal infection, which has a good clinical curative effect for postoperative severe abdominal infection .
