Establishing a long-term vascular access in patients exhibiting vascular access exhaustion is challenging. In this study, we reported a case of a direct catheterization in the superior vena cava of a hemodialysis patient with vascular access exhaustion and original dysfunctional catheter inserted via the left internal jugular vein. The direct catheterization was performed with cuffed tunnel catheter (CUFF) and guided by digital subtraction angiography (DSA) and multidetector computed tomography venography (MDCTV). The DSA and MDCTV results revealed an occlusion in the right innominate vein and thromboses in the left innominate, right internal jugular, subclavian, and femoral veins. The distal end of the superior vena cava was localized clearly by the original CUFF under DSA. Directed at the distal end of the superior vena cava, a 0.5-cm secondary puncture was introduced below the lateral head of the sternocleidomastoid muscle via the right neck area. This study is one of the few reports regarding direct catheterization of CUFF via the superior vena cava of a patient with vascular access exhaustion and CUFF dysfunction on the left internal jugular vein. We believe that our study can provide a new alternative for inserting central venous catheter for such patient.

我们研发了一种新型的血管内光学相干成像术(IV-OCT),该技术能极其快速地实现冠状动脉成像,并通过消除心脏运动伪影和欠采样以实现图像的更高质量。它所依赖的成像探头包括一个直径为1.0 mm 且转速为5600 rev·s–1的同步微电机,使IV-OCT 的帧频达到5.6 kHz,并使用每秒产生280 万图像扫描线的波长扫描激光器。通过使用该设备,我们团队在设置速度为100 mm·s–1时实现了体外5600 fps 和体内4000 fps 的成像速度。由实验对象的心电图触发整个图像采集过程,当心脏在跳动过程中相对不强烈时扫描冠状动脉,因此该技术还有一个新名字,"心动光学相干成像术"(Heartbeat OCT)。

增强对流输注 (CED) 是一项颇具前景的技术,其借助压力驱动流来增强输注药物进入细胞间隙的穿透力。为进一步提升CED的药物分布容积,笔者发明了一种可产生局部亚致死热量的光纤微针装置。本文试图在琼脂糖组织模型中对该技术进行定量表征。在15 °C、20 °C、25 °C和30 °C的恒温条件下,染料的输注在质量分数为0.6%的琼脂糖组织模型中进行分析。输注指标通过自定义阴影成像技术和图像处理算法进行定量。利用所获数据构建一个分布容积的经验预测时序模型作为组织模型温度的函数。接下来通过一组概念验证实验来评估液体输注时新型光纤装置产生局部光加热的能力。恒温输注显示温度和分布容积呈正相关,在100 min时,在30 °C恒温条件下体积扩散是在15 °C恒温条件下的7倍。在光加热 (1064 nm,500 mW) 过程中,输注呈现相似的效果:与对照组 (0 mW) 相比,输注体积在4 h时增大了3.5倍。本文的分析和结果为体积扩散的热介导增强提供了特征描述及新思路。
