Hepatic Venous Outflow Obstruction after Adult Living Donor Liver Transplantation

Letter to the Editor: Blocked drain switch—hepatic venous outflow obstruction

“…Balloon angioplasty and/or stent placement have become the primary treatment for HVOO after liver transplantation. The recent study by Sambommatsu et al, [1] published in Liver Transplantation, analyzing the clinical data from 16/324 (4.9%) patients with HVOO, underscored the morphology of HVOO and corresponding treatment plan. They recommended repeat balloon angioplasty be considered for simple anastomotic stenosis, but stent placement was recommended for kinks or intrahepatic stenosis.…”

“…To the editor, We thank Dr. Guo and colleagues for their interest in our manuscript published in Liver Transplantation regarding hepatic venous outflow obstruction after adult living donor liver transplantation. [1] They discussed 2 different choices of venous access (femoral and internal jugular) and highlighted the differences in procedurerelated risks and successful rates of these 2 accesses. They suggested that we should provide more information about the selection of interventional radiology access to guide clinical practice.…”
