胚胎学发育 子左上腔静脉(LSVC) ,也称永存左上腔静脉,在正常胚胎发育中,左前主静脉逐渐闭塞,而右侧前主静脉与Cuvier管发育形成上腔静脉。如两侧前主静脉交通支发育障碍, Cuvier管发育,则形成永存左上腔静脉,是最常见的体循环静脉畸形,占心血管病的2%-4%。多引流入冠狀静脉窦,可合并其他先天畸形。 正常胎儿期静...
First described in the literature by Edwards and DuShane in 1950, the persistent left superior vena cava (PLSVC) is the most common venous anomaly of the thorax affecting 0.5% to 2% of the general population and up to 10% of patients with congenital abnormalities of the heart.1 Persistence ...

Left Superior Vena Cava (LSVCendocavitary catheterThe variations on the venous system's conformation are closely related with the embryological development, due to atrophy or persistency of embryological connections that this system establishes for its final formation. During a routine dissection of a ...
