Summary
Ultrasound (US) guidance for inferior vena cava (IVC) stent placement is effective for Budd-Chiari syndrome, offering a safe, non-radiating alternative. This method achieved a 95% success rate, improving patient symptoms and hepatic outflow.
Area of Science:
- Interventional Radiology
- Vascular Surgery
- Medical Imaging
Background:
- Inferior vena cava (IVC) stent placement traditionally relies on fluoroscopic guidance.
- Budd-Chiari syndrome management often involves addressing IVC obstruction.
Purpose of the Study:
- To evaluate ultrasound (US) as a guidance modality for IVC stent placement.
- To assess the efficacy of US-guided IVC stenting in managing Budd-Chiari syndrome.
Main Methods:
- Eighty-three patients with various IVC obstructions underwent US-guided recanalization, balloon dilation, and stent placement.
- Patients presented with membranous stenosis/occlusion or segmental stenosis/occlusion of the IVC.
Main Results:
- Successful IVC stent placement was achieved in 95% (79/83) of patients.
- Symptoms of IVC obstruction resolved or improved significantly in all patients; hepatic outflow obstruction was alleviated in 67 patients.
- Complications were rare, including one instance each of pericardial effusion, atrioventricular block, and stent migration. Restenosis occurred in one patient during follow-up.
Conclusions:
- Ultrasound (US) is a suitable and often preferred guidance method for IVC stent placement.
- US offers advantages such as the absence of ionizing radiation and iodinated contrast material.
- The low cost and safety profile make US an attractive option for IVC interventions.
