CT导引下腹部细针穿刺抽吸活检的临床应用

CT Guided Percutaneous Abdominal Fine-needle Biopsy

目的:探讨CT导引下腹部细针穿刺抽吸活检技术方法并评价其临床应用。材料与方法:男20例,女7例,年龄7～88岁。穿刺部位包括肝内肿物10例,胰头肿物3例,脾脏肿物、肾脏病灶各1例,腹、盆腔内肿物9例,腹膜后肿物3例。使用岛津SCT3000TC全身CT扫描机作导引,选用18-22G(150mm)Chiba活检针,选择最佳层面、进针路径及取材点穿刺抽吸。结果:腹部细针穿刺抽吸活检阳性率88.9％,2例首次活检为阴性结果,再次活检得到阳性结果,首次活检阳性率82.8％。无任何并发症。结论:CT导引下腹部细针穿刺抽吸活检正确率高、安全,活检方法简便、实用,可为临床制定治疗方案提供可靠依据。

Purpose: To explore the technical methods and evaluate the clinical applications of CT guided percutaneous abdominal fine-needle biopsy. Materials and methods: 27 cases of abdominal masses located on the liver 10 cases, the head of pancreas 3 cases, the spleen and the kidney 1 case respectively, the peritoneal cavity 9 cases and the retroperi-toneum 3 cases, were performed percutaneous fine-needle biopsy with 18 - 22 Guage aspiration needles under CT guidance. The appropriate crosssection, the puncture route and the point of the aspiration biopsy were selected in each case. Results: The total positive rate of the abdominal biopsy and the positive rate of the first biopsy were 88.9% and 82. 8% respectively. No complications were occoured. Conclusion: CT guided percutaneous abdominal fine-needle biopsy is a safe and effective method for the diagnosis and differential diagnosis with less complication and high accurate rates.
