Clinical value of CEUS guided biopsy in diagnosis of lymphoma in anterior mediastinum / 中国介入影像与治疗学

ABSTRACT

Objective To explore the clinical value of CEUS guided biopsy of lymphoma in anterior mediastinum.Methods The data of 36 patients with lymphoma of anterior mediastinum underwent biopsy guided by CEUS and 36 patients by conventional ultrasound retrospectively.The successful rate of biopsy and rate of complication occurence were compared between the CEUS group and conventional ultrasound group.Results The successful rate of biopsy in CEUS group was 100％ (36/36),including 26 non-Hodgkin's lymphoma (NHL),10 Hodgkin's lymphoma (HL).The total times of puncture were 60 in 36 patients.The rate of complication occurrence was 11.11 ％ (4/36).The successful rate in conventional ultrasound group was 88.89％ (32/36),including 22 NHL,14 HL.The times of puncture were 91 in 36 patients.The rate of complication occurrence was 41.67％ (15/36).There were significant differences in successful rate and the rate of complication occurrence between two groups (x2 =4.235,8.651,P=0.040,0.003).Conclusion CEUS can reflect the microcirculation of lymphomas in anterior mediastinum,and can guide targeted biopsy.It can improve the successful rate of biopsy and reduce the complications.
