Extracorporeal suture technique for suprahepatic caval anastomosis in liver transplantation

Successful Deceased Donor Liver Transplantation with Median Sternotomy for Budd-Chiari Syndrome: A Case Report and Review of the Literature

INTRODUCTION

When a thrombus extends to the suprahepatic inferior vena cava (IVC) in patients with Budd-Chiari syndrome (BCS) requiring liver transplantation (LT), there is a risk of thrombus migration during hepatectomy that can potentially lead to pulmonary embolism. Intraoperative pulmonary embolism can be life-threatening and may necessitate urgent thrombectomy. However, preventive strategies for pulmonary embolism during LT in BCS cases with IVC thrombosis have seldom been discussed in the literature. We report a case involving a 51-year-old woman with BCS complicated by thrombi extending into the suprahepatic IVC who underwent deceased donor LT (DDLT) for acute liver failure (ALF).

CASE PRESENTATION

A previously healthy 51-year-old woman with ALF secondary to BCS was admitted to our hospital. 19 days back, BCS was diagnosed at another hospital, where computed tomography revealed thrombi in the hepatic veins and IVC. She subsequently developed grade II hepatic encephalopathy and severe liver dysfunction. Conservative treatment was ineffective, and 4 days before the current admission, she experienced grade III hepatic encephalopathy and showed hepatofugal portal flow on ultrasonography. DDLT was performed on day 13 after admission. Median sternotomy was performed to clamp the suprahepatic IVC near the right atrium, mitigating the risk of thrombus migration during hepatectomy and allowing for urgent thrombectomy in case of pulmonary embolism. Additionally, because a large-for-size graft was being used, the median sternotomy enhanced visibility and provided adequate space, facilitating suprahepatic IVC anastomosis. Postoperatively, the patient experienced no complications related to the sternotomy and was discharged 58 days after surgery.

CONCLUSIONS

This case report highlights the potential utility of median sternotomy during LT for BCS, particularly for cases with concerns regarding thrombus migration from the suprahepatic IVC, the need for rapid thrombectomy in the event of pulmonary embolism, and anticipated challenges in suprahepatic IVC anastomosis due to large-for-size grafts.

[Significance and specificity of vascular anastomosis in liver transplantation -- our experience]

INTRODUCTION

Transplantation is the method of choice in the treatment of terminal liver diseases with acute and structural damage of liver tissue and congenital liver diseases.

OBJECTIVE

The aim of our study was to determine specificity and significance of vascular anastomosis in liver transplantation by postoperative evaluation of vascular anastomosis function.

METHOD

The study included 16 patients with 16 liver transplantations and one re-do liver transplantation. In all patients, preoperative angiography and postoperative duplex sonographic and angiographic evaluation of vascular anastomosis were performed.

RESULTS

Preoperative angiographic evaluation did not reveal anomalies in liver blood vessels of transplant candidates. In one patient, we identified and angiographically confirmed stenosis on anastomosis of the hepatic artery on the 7th postoperative day. In another patient, we had artificial thrombosis of the hepatic artery branch due to the liver biopsy.

CONCLUSION

The successful performance of vascular anastomosis in liver transplantation is significant for adequate liver graft perfusion, good postoperative graft function and overall outcome of the liver transplantation.
