- W2374402008 abstract "Objective To evaluate the value of gray-scale contrast-enhanced ultrasound (CEUS) in the therapy of microwave tissue coagulation (MTC) for hepatic trauma. Methods Thirty-two hepatic trauma of grade II with active hemorrhage were created in 7 porcine livers. The power of MTC was 70W and 80W respectively. Conventional ultrasound and CEUS were performed before and after MTC. Results Conventional ultrasound was not able to detect the specific location of the active hemorrhage in any of the livers evaluated before MTC. After injecting contrast agent, all bleeding sites could be detected by CEUS which could be used to guide the inserting of microwave electrode successfully. After MTC, CEUS showed that the sizes of 70 W and 80 W groups were ([4.61±0.39] cm, [4.71±0.57] cm) (t=-0.48, P0.05) in length and ([3.03±0.60] cm, [2.77±0.41] cm) (t=1.14, P0.05) in width, respectively. The centre area of the therapeutic region was not enhaned in both groups which was the results of necrotic hepatic vessels and liver cells proved by pathology. A few enhanced regions could be seen in the periphery area in 56.2% of 70 W and in 37.5% of 80 W therapeutic regions. Conclusion CEUS is useful in guiding the inserting of microwave electrode and could be used to assess the curative effect of MTC for hepatic trauma." @default.
