概括

大脑血管形 (VMs) 很少会在遗传性出血端膜病 (HHT) 患者中重新形成. 这一发现表明,对于HHT患者来说,可能需要定期进行大脑VM重新选.

科学领域:

神经学神经学
遗传学是一个遗传学.
血管医学血管医学

背景情况:

遗传性出血端膜切除症 (HHT) 影响大约10%的脑血管形患者.
有限的数据存在于HHT患者的de novo大脑VM形成.
目前的HHT指南建议在儿童中进行初步的大脑VM查,但缺乏对重新查的指导.

研究的目的:

为了调查在被诊断为遗传性出血端膜病 (HHT) 的患者中出现新的脑血管形 (VMs) 的情况.

主要方法:

一项纵向研究涉及17个中心的1909名患者,自2010年以来就读.
分析 de novo VMs,定义为后续神经成像上的新形成或独特的新位置.
中央神经成像审查,以确认新的VM病例.

主要成果:

在1909名患者中,有409人 (21%) 患有脑虚拟机. 最初记录了7名患者使用de novoVMs,其中3人得到证实 (0.7%的VMs患者).
确认的de novoVM包括两个毛细血管形和一个大脑动脉静脉形,在初始成像后的6,9年和13年检测到.
在三名患有de novoVM的患者中,有两名是未成年人. 一个孩子显示了现有的大脑动脉静脉形的生长,而不是新的.

结论:

脑血管形 (VMs) 可以在遗传性出血端膜病 (HHT) 患者中发展,尽管很少发生.
与大脑VMs相关的潜在出血风险强调了考虑HHT患者定期重新查协议的重要性.

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...
