BACKGROUND
To investigate the role of upper extremity radionuclide venography as a potential diagnostic modality in the assessment of venous thrombosis associated with a Port-A catheter.
METHODS
Fourteen symptomatic patients who had received Port-A catheter implantation were enrolled. A dynamic nuclear medicine flow study was performed with intravenous administration of Technetium-99m macroaggregated albumin to both upper extremities. Imaging patterns of the venous system were categorized as patency, partial obstruction, and total occlusion.
RESULTS
The findings of the dynamic images clearly demonstrated clinical problems. Three patients were free of a definite venous flow change. Three patients had partial obstruction of venous return. A significant cut-off of venous return was demonstrated in 8 patients, and total occlusions were hence diagnosed. All patients underwent this procedure smoothly without any complication.
CONCLUSION
These results suggest that upper extremity radionuclide venography is an easily performed and effective method for diagnosing Port-A catheter thrombosis in clinical practice.
背景
探讨上肢放射性核素静脉造影作为一种潜在诊断方法在评估与输液港导管相关的静脉血栓形成中的作用。
方法
纳入14例接受输液港导管植入术且出现症状的患者。通过静脉注射锝-99m标记的大颗粒白蛋白对双上肢进行动态核医学血流研究。静脉系统的成像模式分为通畅、部分阻塞和完全阻塞。
结果
动态图像的结果清楚地显示了临床问题。3例患者未出现明确的静脉血流变化。3例患者存在静脉回流部分阻塞。8例患者出现明显的静脉回流中断，因此诊断为完全阻塞。所有患者均顺利完成该检查，无任何并发症。
结论
这些结果表明，上肢放射性核素静脉造影在临床实践中是一种易于实施且有效的诊断输液港导管血栓形成的方法。
