概括

管道栓塞装置植入后,血管重塑,而不仅仅是内皮细胞过度生长,是关键. 动脉向外重塑可以抵消新极的过度生长,保持血管通透性.

科学领域:

内血管外科手术是什么意思
脑血管疾病是脑血管疾病.
医疗器械技术医疗器械技术

背景情况:

内皮细胞过度生长被认为是成功的流量转移器后内皮膜重建的关键.
血管改造,血管对流量调节器植入的动态反应,不那么强调,但很重要.
血管造影方法可以对这些植入后变化进行有用的观察.

研究的目的:

在部署管道栓塞装置后,对目标血管的可观察到的植入后变化进行定量评估.
评估血管改造与内皮质化不同的作用.

主要方法:

这项研究涉及100名患有动脉瘤的成年人,他们接受了带有盾牌技术的管道栓塞装置的治疗.
随访常规血管造影 (2D DSA) 用于分析目标血管大小,装置直径和内皮厚度.
人口,抗血小板和设备相关的参数被记录和分析.

主要成果:

新极端过度生长的厚度 (平均0.3毫米) 与年龄相反相关,并且独立于其他分析参数.
外向动脉重塑抵消了从新极端的过度生长中减少的光圈直径.
外部改造与植入装置的相对直径之间发现了直接关系,改造直径减少了15%.

结论:

流量调节器植入后的血管愈合包括对外重塑和新极端过度生长.
设备的司法超大尺寸可以被认为是为了抵消光量减少,平衡金属覆盖率下降.
对其他设备进行进一步分析是必不可少的.

Mechanism of Angiogenesis

Mechanism of Angiogenesis

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

Regulation of Angiogenesis and Blood Supply

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...
