The accuracy of ultrasonography (US) in delineating the portal vascular anatomy was assessed clinically by the clinician in 30 cases of portal hypertension due to noncirrhotic portal fibrosis and extra hepatic portal venous obstruction. Ultrasonography detected portal vein block in 19 and in 11 patients it was found to be patent. These ultrasonic diagnoses were confirmed by spleno-portovenography (SPV) in all, except in 2 cases due to technical failure. Ultrasononic assessment of the splenic vein was found to be accurate in 93.3% (28/30) of cases. SPV also had similar accuracy of splenic vein assessment when compared with the surgical findings. In one patient, intraperitoneal haemorrhage was encounted following SPV, necessitating emergency surgery. Thus, US was found to be as accurate as splenoportovenography in the assessment of portal vascular anatomy. The imaging technique is cheap, easy, safe, and can be repeated as often as necessary. It should be the procedure of choice in assessing the anatomy of portal vascular system.
临床医生对30例非肝硬化性门静脉纤维化和肝外门静脉阻塞所致门静脉高压患者，通过超声检查（US）评估其在描绘门静脉血管解剖结构方面的准确性。超声检查发现19例存在门静脉阻塞，11例门静脉通畅。除2例因技术失败外，所有这些超声诊断均经脾门静脉造影（SPV）证实。超声对脾静脉的评估在93.3%（28/30）的病例中是准确的。与手术结果相比，SPV对脾静脉的评估准确性也相似。1例患者在SPV后发生腹腔内出血，需紧急手术。因此，发现超声在评估门静脉血管解剖结构方面与脾门静脉造影一样准确。该成像技术价格便宜、操作简便、安全，且可根据需要多次重复。它应是评估门静脉血管系统解剖结构的首选检查方法。
