概括

形状记忆聚合物 (SMP) 栓塞塞在腹腔大动脉动脉瘤 (AAA) 中治疗II型内泄 (T2ELs) 方面显示出前景. 然而,这一案例系列在六个月内只发现了43%的AAA增长,这表明挑战仍然存在.

科学领域:

血管外科血管外科
干预性放射学干预性放射学
生物材料科学生物材料科学

背景情况:

与腹腔大动脉动脉瘤 (AAA) 囊扩张的II型内孔 (T2ELs) 需要治疗,但持久的内血管选择有限.
形状记忆聚合物 (SMP) 栓塞插头为内血管修复提供快速填充空间和血栓支持.

研究的目的:

为了评估超端移植激光结合SMP栓塞治疗具有挑战性的T2ELs的疗效.
在1个月和6个月的随访中,评估持续的腹腔大动脉动脉瘤囊生长率.

主要方法:

七名患者的回顾性审查,这些患者接受了T2ELs的跨内移植激光化和SMP栓塞.
激光化针对内脏漏洞,随后是SMP插头部署和内脏移植重新调整.
主要结局:在1个月和6个月的随访期间,持续的动脉瘤囊生长.

主要成果:

该队列包括了先前有各种动脉瘤修复和干预的患者.
中位数AAA直径为75.0毫米,之前有显著的增长.
三名患者在术后经历了持续的AAA增长,需要重新干预;整体6个月的AAA增长率为42.9%.

结论:

在大约43%的患者中,通过传输移植激光化和SMP栓塞实现了6个月的AAA增长自由.
复杂动脉瘤疾病中的耐火T2ELs存在挑战.
SMP栓塞具有作为T2EL的最小侵入性治疗的潜力,未来的程序改进.

Ligand-Gated Ion Channel Receptor: Gating Mechanism

Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...
