A retrospective study of 34 consecutive patients with possible tumour involvement of the vena cava was performed to assess the usefulness of intracaval ultrasonography. Twenty-five of the 34 patients were operated and resection carried out in 23, including seven with combined resection of the vena cava. The sonographic criterion for vena cava invasion was obliteration of the echogenic ring of the vena cava wall or intracaval tumour mass. The sensitivity, specificity and overall accuracy of intracaval endovascular ultrasonography in the diagnosis of tumour involvement of the vena cava were 100, 96 and 97 per cent respectively. The respective values were 91, 61 and 71 per cent for computed tomography and 82, 67 and 72 per cent for cavography. Ultrasonography is a useful technique that can precisely evaluate the vena cava for possible tumour invasion, especially when the presence or extent of tumour involvement is not definitely established by conventional imaging techniques.
对34例连续的可能存在腔静脉肿瘤累及的患者进行了一项回顾性研究，以评估腔内超声检查的效用。34例患者中有25例接受了手术，其中23例进行了切除，包括7例腔静脉联合切除。腔静脉侵犯的超声标准是腔静脉壁回声环消失或腔内肿瘤块。腔内血管超声检查诊断腔静脉肿瘤累及的敏感性、特异性和总体准确性分别为100%、96%和97%。计算机断层扫描的相应值分别为91%、61%和71%，静脉造影的相应值分别为82%、67%和72%。超声检查是一种有用的技术，可精确评估腔静脉是否可能受肿瘤侵犯，尤其是当传统成像技术不能明确肿瘤累及的存在或范围时。
