Core Tip
Core Tip: Percutaneous, image-guided medical liver biopsies are an invaluable tool in the diagnosis of a wide variety of hepatic diseases and conditions. Despite advances in tools and techniques, bleeding remains a frequent post-procedural complication, sometimes with significant sequelae. The SinglePass Kronos device was developed to provide hemostasis within the biopsy needle tract via electrocautery. This series of 5 case reports on Kronos use following percutaneous liver biopsy demonstrates Kronos integration into biopsy workflow with no post-procedural bleeding complications through 30 days. The Kronos device may be a valuable tool in preventing bleeding complications in percutaneous liver biopsies.
