Intraoperative and postoperative impact of pretransplantation transjugular intrahepatic portosystemic shunts in orthotopic liver transplantations: A systematic review and meta-analysis.

Objectives: Orthotopic liver transplantation (OLT) remains the definitive treatment for patients afflicted with end-stage liver disease (ESLD). Transjugular intrahepatic portosystemic shunts (TIPS) have been adapted as a bridge to transplantation, allowing partial normalization of portal pressure and associated symptom improvement. Conflicting evidence exists on TIPS' impact on operative procedures.

Randomized Controlled Trials in Pediatric Cardiology: A Power Struggle?

Sample size and statistical power are often limited in pediatric cardiology studies due to the relative infrequency of specific congenital malformations of the heart and specific circulatory physiologies. The primary aim of this study was to determine what proportion of pediatric cardiology randomized controlled trials achieve an 80% statistical power. Secondary aims included characterizing reporting habits in these studies.

Operative safety of orthotopic liver transplant in patients with prior transjugular intrahepatic portosystemic shunts: A 20-year experience.

Introduction And Aims: Orthotopic liver transplant (OLT) is the definitive treatment of most types of liver failure. Transjugular intrahepatic portosystemic shunt (TIPS) and portocaval shunt placement procedures reduce the systemic vascular complications of portal hypertension. TIPS placement remains a "bridge" therapy that enables treatment of refractory symptoms until transplantation becomes available.

Endovascular Treatment of Transplant Renal Artery Stenosis: A Systematic Review and Meta-analysis.

Objective: Endovascular treatment through either percutaneous transluminal angioplasty (PTA) alone or stenting has been previously used as a treatment for transplant renal artery stenosis (TRAS). This review aimed to investigate the results of endovascular treatment for renal artery stenosis in transplanted kidneys as compared with the outcomes of interventions, medical management, and graft survival in non-TRAS patients.

Methods: A systematic review of PubMed, Google Scholar, Cochrane, and Scopus was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines in which studies that reported outcomes of the treatment of TRAS via the endoluminal approach were identified, and their results were meta-analyzed.
