名词:可视栓塞微粒 radiopaque beads为什么需要可视栓塞微粒(背景)?1. DEBs是透光的(radiolucent) 2. 应用时在体外与造影剂混合 3. 药物洗脱微球的真实位置是不知道的
可视性栓塞微粒
Suk Oh J et al. JVIR 2013;24:483-9
可视微球 从可视到可释放 Visibility ↔ deliverability
early designs: difficult handling + administration due to rapid sedimentation
早期设计:由于快速沉降,处理+实施困难
可视微球的合成 Radiopaque Beads SynthesisDuran R et al. Theranostics 2016;6:28-39 可视微球 从试验到临床
1. 这是关于ROBs第一次临床经验的技术说明 Technical note on first clinical experience with ROBs
2. LC Bead LUMI 粒径 70-150 μm
3. 患者肝癌,类癌和神经内分泌肿瘤 patients (HCC, carcinoid & NET)
4. 在透视、DSA和CBCT监视下经动脉栓塞 Intra-proc. monitoring: fluroscopy, DSA & CBCT
5. 术后48小时CT Post-proc MDCT @48h
回肠内分泌肿瘤患者,61岁男性,肝脏IV段5.5cm病变

可视微球的药物荷载Ashrafi K et al. J Control Release. 2017 Mar 28;250:36-47 可视微球的可视性
可视性药物洗脱微球的展望明显的优势(Clear advantages)
- 非靶和靶向区域的识别(Identification of non/targeted area)
- 识别未得到治疗的区域(Identification of regions at risk of being untreated)
- 标记血管以便后续治疗(Marking vessels for subsequent treatment)
待定(To be determined)- 有助于实时调整操作??? (Helpful to modify the procedure in real time???)
- 决定栓塞终点???(Embolization endpoint determination ???)
- 药物剂量与肿瘤反应相关???(Drug-dose painting ↔ tumor response ???)
- 可视微球带来的新信息可以解释更好的结果吗???(Is the added info going to translated in better outcomes ???)
