Abstract

Abstract: Introduction: Among various reported techniques for inferior vena cava (IVC) reconstruction, the superiority of one technique over another has not been clearly established. This study aimed at reporting the technical aspects of caval reconstruction using peritoneal patch during extended liver resections. Methods: All consecutive patients who underwent extended liver resection associated with anterolateral caval reconstruction using a peritoneal patch from 2016 to 2019 were included in this study. Technical insights, intra-operative details, short and long-term results were reported. Results: Overall six patients underwent caval reconstruction using peritoneal patch under total vascular exclusion. Half of them required veno-venous bypass. Caval involvement ranged from 30 to 50% of the circumference and from 5 to 7 cm of the length of the IVC. Caval reconstructions was performed using a peritoneal patch harvested from the falciform ligament in four cases and from the right pre-renal peritoneum and right part of the diaphragm in one Case each. Three cases underwent associated reimplantation the remnant hepatic vein. Median intra-operative blood loss and TVE duration were 500 ml and 41 min, respectively. One case experienced a severe complication (liver failure leading to death). R0 resection was achieved in all patients. All patients had patent IVC and remnant hepatic vein at last follow-up and none was on long-term therapeutic anticoagulation. Conclusion: Caval reconstruction using a peritoneal patch in patients undergoing extended liver resection is feasible and cost-effective and associated with excellent long-term results. Highlights: The peritoneal patch is a safe and cost-effective graft for caval reconstruction. Its plasticity makes it suitable for hepato-caval confluent reconstructions. Falciform ligament should be harvested in Case of anticipated caval involvement.
