术中、术前B超和X线造影在Budd—Chiari综合征诊断中的对比分析

A Comparative Study on Use of Intraoperative Ultrasonography and Preoperative Ultrasonography and Inferior Vena Cavography for Diagnosing the Budd-Chiari Syndrome

对13例梗阻型B-CS患者进行了术中B超和术前B超及X线造影检查,结果表明:术前B超和X线造影检查在B-CS诊断中起定性分析和粗略定量分析的作用。但存在不足之处:①术前B超因肠腔气体干扰,部分病例的病灶显示欠佳。②X线造影剂不易逆行入肝静脉,故肝静脉梗阻难以显示,影响了术式选择。术中B超则弥补了上述不足。经手术证实,病灶显示完全,对术式选择具有指导意义,且术中即可评判手术效果。因而在B-CS诊断中,术中B超具有不容忽视的重要作用。

Thirteen cases of Budd-Chiari syndrome were studied by intraoperativeultrasonography (IOUS), preoperative ultrasonography (POUS) and inferior vena cavography. The result showed that the POUS and inferior vena cavography played a role of qualitative analysis and roughly quantitative analysis in diagnosis of the Budd-Chiari syndrome. The shortages were: (1) the diseased part of some cases could not been seen very clear because of the interruption of the gas in the intestine; (2) under x-ray, for the contrast agent was not easy to enter the hepatic vein, so the obstruction of the hepatic veins was diffcult to be seen. It disturbed the selection of appropriate surgical procedure. IOUS made up for the deficiency.mentioned above. The diseased part in vena was showed completely and confirmed by the surgery. Intraoperative ultrasonography was used to guide the selection of surgical procedure and was able to evaluate the effect during operation. On diagnosing the Budd-Chiari syndrome, IOUS takes an important role.
