Acute iatrogenic Budd-Chiari syndrome following hepatectomy for hepatolithiasis: a report of two cases.

Budd-Chiari syndrome (BCS) is defined as hepatic venous outflow obstruction at any level from the small hepatic veins to the junction of the inferior vena cava (IVC) and the right atrium, regardless of the cause of obstruction. We present two cases of acute iatrogenic BCS and our clinical management of these cases. The first case was a 43-year-old woman who developed acute BCS following the implantation of an IVC stent for the correction of stenosis in the IVC after hepatectomy for hepatolithiasis. The second case was a 61-year-old woman with complete obstruction of the outflow of hepatic veins during bilateral hepatectomy for hepatolithiasis. Acute iatrogenic BCS should be considered a rare complication following hepatectomy for hepatolithiasis. Awareness of potential hepatic outflow obstructions and timely management are critical to avoid poor outcomes when performing hepatectomy for hepatolithiasis.
