哺乳动物包括人,供给腺垂体的大部分血液是来自下丘脑—正中隆起区,经由长门脉血管。但动物实验研究显示,其血供也从下丘脑远部,经由短门脉血管逆行运输,并在垂体形成环状迂回的血流。 作者对10例因患垂体脉瘤而施行穿蝶微型手术的病人,在其收集垂体柄血液以研究下丘脑儿茶酚胺分泌时,同时进行PRL分泌的研究。简言之,即在手术当天、术前3天和术后3天,同步收集下丘脑— Mammals, including humans, supply most of the blood of the pituitary gland from the hypothalamus-middle uplift region via long portal veins. However, animal experimental studies have shown that the blood supply is also retrogradely transported from the hypothalamus, via the short portal vein, and forms a torroidal blood flow in the pituitary. The authors performed studies on the secretion of PRL in 10 cases of patients undergoing microsurgery for pituitary tumors when they collected blood from the pituitary stalk to study hypothalamic catecholamine secretion. In short, on the day of surgery, 3 days before surgery, and 3 days after surgery, the hypothalamus was collected synchronously—
