Patients with vena caval (VC) thrombosis have been reported with a variety of clinical presentations, which may create a diagnostic challenge for physicians.
The objective of the study was to evaluate the clinical characteristics of patients with VC thrombosis.
Files and all imaging methods of consecutive patients with superior or inferior VC thrombosis with or without pulmonary embolism (PE) between January 26, 2001, and May 12, 2006, were retrospectively studied in detail.
In our series, VC thromboses within the inferior and superior VC were detected in 28 patients, mostly by combined computed tomographic venography and spiral computed tomographic pulmonary angiography. Nine of these 28 patients (32.1%) had VC thromboses without PE (7 patients with isolated and 2 patients with nonisolated VC thrombosis). Key symptoms and findings in the 9 patients without PE were unexplained dyspnea and tachypnea, respectively.
Many patients with VC thrombosis do not have peripheral vein thrombosis. Moreover, nearly one third of patients with VC thrombosis have negative pulmonary angiograms but do have dyspnea and tachypnea.
已有多种临床表现的腔静脉（VC）血栓形成患者的报道，这可能给医生的诊断带来挑战。
本研究旨在评估 VC 血栓形成患者的临床特征。
详细回顾了 2001 年 1 月 26 日至 2006 年 5 月 12 日期间连续就诊的伴有或不伴有肺栓塞（PE）的上腔或下腔 VC 血栓形成患者的病历和所有影像学方法。
在我们的系列研究中，28 例患者中检测到下腔和上腔 VC 血栓形成，主要通过联合计算机断层静脉造影和螺旋计算机断层肺动脉造影进行检测。这 28 例患者中有 9 例（32.1%）无 PE 的 VC 血栓形成（7 例为孤立性 VC 血栓形成，2 例为非孤立性 VC 血栓形成）。9 例无 PE 的患者的主要症状和发现分别为不明原因的呼吸困难和呼吸急促。
许多 VC 血栓形成患者没有外周静脉血栓形成。此外，近三分之一的 VC 血栓形成患者肺动脉造影阴性，但有呼吸困难和呼吸急促。
