EE-103 - Intra-operative contrast enhanced sonographic assessment of liver metastatic disease
Abstract
Objectives
The purpose of this presentation is to discuss the use of intraoperative contrast-enhanced ultrasound (CEUS) in evaluation of metastatic disease of the liver.
Background
Intraoperative ultrasound with contrast agent is a dedicated method of investigating metastatic liver disease in patients that perform surgical excision of primary cancer and metastatic deposits at the same time. This is common practice in patients with colorectal carcinoma and metastatic disease. The use of sonographic contrast agent has been reported as more efficient in detecting occult liver metastases, especially in colorectal cancer post chemotherapy and after radiofrequency ablation (RF).
Imaging findings OR Procedure findings
Intraoperative ultrasound is performed initially in order to identify anatomic landmarks of the liver and patency of major vessels. Subsequently, administration of contrast agent with standard technique is performed for mapping of known metastatic deposits and identification of potential occult lesions. The use of contrast agent can be performed post RF and may assess the effectiveness of ablation intraoperatively.
Conclusion
Intraoperative ultrasound with contrast agent is an imaging method that may contribute to successful surgical and therapeutic management of metastatic liver disease, with emphasis on colorectal carcinoma.
