Insights
Hepatic vein stenting offers a lasting solution for Budd-Chiari syndrome. A novel technique using balloon occlusion of the inferior vena cava successfully retrieved a migrated stent, avoiding cardiopulmonary bypass.
Area of Science:
- Interventional cardiology
- Vascular surgery
Background:
- Budd-Chiari syndrome can necessitate hepatic vein stenting.
- Stent migration to the right atrium is a rare but serious complication.
- Surgical retrieval of migrated stents often requires cardiopulmonary bypass (CPB).
Observation:
- A case of hepatic vein stent migration into the right atrium is presented.
- Conventional retrieval methods carry risks associated with CPB and circulatory arrest.
Findings:
- A hybrid technique employing vena caval inflow occlusion (VCIO) using a balloon catheter was utilized for stent retrieval.
- This method successfully occluded the inferior vena cava, facilitating stent retrieval.
- Cardiopulmonary bypass and total circulatory arrest were avoided during the procedure.
Implications:
- This hybrid VCIO technique offers a viable alternative for managing migrated hepatic vein stents.
- It potentially reduces the risks and complications associated with traditional CPB-dependent retrieval.
- This approach may improve patient outcomes in rare cases of stent migration.
Abstract:
Stenting of hepatic veins can be a long lasting solution for Budd-Chiari syndrome. These stents could very rarely migrate into the right atrium. During surgical retrieval, cardiopulmonary bypass (CPB) can be avoided if vena caval inflow occlusion (VCIO) is used. A hybrid alternative of VCIO by using a balloon to occlude the inferior vena cava was done to retrieve the stent thus avoiding CPB and total circulatory arrest.
