一、超声介入用于诊断方面主要为超声引导下穿刺活检及腔内超声的应用。 (一) 对出凝血功能障碍病人行超声引导下栓塞针路的肝穿刺活检:Zins等对53例有出血倾向的病人应用了该项技术。方法是首先在超声引导下行肝穿刺,然后通过拔针后留下的套管向针路内注入明胶海绵颗粒,以栓塞针路,结果有95％的病人获得成功。仅发生2例有较严重的并发症(一例腹腔内大量出血,一例肝内血肿)。本技术初步证实,栓塞针路肝活检,能有效的防止大量出血的发生,有较高的实用价值。 (二) 腔内超声:主要为腔内探头及超声内镜的应用。在妇产科方面的研究有经阴道超声及宫腔内探头的应用。Distantis等对37例绝经后妇女共70个卵巢 One, ultrasound intervention for diagnosis is mainly the application of ultrasound-guided needle biopsy and intracavity ultrasound. (i) Liver biopsy of ultrasound-guided embolization for patients with coagulopathy: Zins et al. applied this technique to 53 patients with bleeding tendencies. The method is to first conduct hepatic puncture under ultrasound guidance, and then inject gelatin sponge particles into the needle path through the cannula left after needle removal to embolize the needle path. As a result, 95% of the patients were successful. Only 2 cases had more serious complications (one case of massive intra-abdominal bleeding and one case of intrahepatic hematoma). This technique has initially confirmed that embolization needle liver biopsy can effectively prevent the occurrence of massive bleeding and has a high practical value. (B) Intracavity ultrasound: mainly for endoluminal probes and ultrasound endoscopic applications. Research in obstetrics and gynecology has been applied to transvaginal ultrasound and intrauterine probes. Distantis et al. on 70 ovaries in 37 postmenopausal women
