Endovascular Treatment of Venous Outflow and Portal Venous Complications After Liver Transplantation.

Liver transplantation continues to rapidly evolve, and in 2020, 8906 orthotopic liver transplants were performed in the United States. As a technically complex surgery with multiple vascular anastomoses, stenosis and thrombosis of the venous anastomoses are among the recognized vascular complications. While rare, venous complications may be challenging to manage and can threaten the graft and the patient.

Cholecystostomy as an Exclusive Access to Remove Cystic, Common Hepatic, and Common Bile Duct Stones.

The purpose of this article was to evaluate the feasibility and efficacy of percutaneous fluoroscopic-guided stone retrieval from the cystic duct and antegrade common bile duct (CBD) stone advancement into the duodenum exclusively through a cholecystostomy tube. Twenty-one patients with acute cholecystitis and choledocholithiasis or an impacted cystic duct stone who underwent percutaneous cholecystostomy tube placement were retrospectively enrolled in this study. The patients had a contra-indication for cholecystectomy (17 patients because of comorbidities and one who declined surgery) or had failed endoscopic retrograde stone removal attempts (three patients).

Hepatic venous pressure gradient correlates with advanced hepatic fibrosis: a retrospective review.

Purpose: To determine if hepatic venous pressure gradient (HVPG) correlates with advanced hepatic fibrosis, as a complement to transjugular (transvenous) core needle liver biopsy.

Materials And Methods: After institutional review board approval, a retrospective review was conducted on 340 patients who underwent transjugular (transvenous) core needle liver biopsy with concurrent pressure measurements between 6/1/2007 and 6/1/2013. Spearman correlation and linear regression were performed.

A multidisciplinary quality improvement program increases the inferior vena cava filter retrieval rate.

Published reports indicate low retrieval rates for retrievable inferior vena cava (IVC) filters. We performed a historic-controlled study of a 5-year intervention (March 2007 to February 2012) to improve IVC filter retrieval rates at a university medical center serving a rural area. All adults with a retrievable filter placed were included, except those with a life expectancy <6 months.

Angiographic embolization is safe and effective therapy for blunt abdominal solid organ injury in children.

Background: : Angiographic embolization (AE) is used to control hemorrhage in adult blunt liver, spleen, and kidney (ASO) injuries. Pediatric experience with AE for blunt ASO injuries is limited. We reviewed our use of AE to control bleeding pediatric blunt ASO injuries for efficacy and safety.

Current trends in vena caval filtration with the introduction of a retrievable filter at a level I trauma center.

Objective: The purpose of this study was to document the initial experience, indications, technical success, and complications with an optional vena caval filter at a Level I trauma center.

Methods: The trauma registry and interventional radiology database were reviewed for all venal caval filters placed during a 15-month period. Records were reviewed for age of patient, indication, type of filter, and duration between placement and removal of the filter.

Radiofrequency ablation of renal transitional cell carcinoma with protective cold saline infusion.

Radiofrequency (RF) ablation is a feasible option for treatment of renal tumors when definitive tumor resection is not performed. Renal hilar and ureteral masses are generally more difficult than peripheral renal tumors to approach with RF ablation because of the higher associated risks of injury to the hilar vessels and the collecting system. This report presents a case of RF ablation of transitional cell carcinoma of the ureteropelvic junction, performed successfully for intractable hematuria.
