本文作者曾阐明痔是由于直肠颈部受到肛门直肠带(肛直带)的挤缩而造成的粘膜脱垂,并否定了痔静脉丛充血是痔形成的必要条件。以上发现促使作者重新认识痔静脉丛的解剖。本文对48具有正常直肠泌尿生殖道尸体进行研究,探讨痔静脉丛的解剖及其在痔形成中的作用。 48例尸体,男30,女18。20例为足月生产后夭折的新生儿,余28例年龄为8～58岁。分两组进行血管造影及血管塑形研究。血管造影组:25例,使用20%硫酸钡水溶液为造影剂。暴露7例新生儿肠系膜下静脉,在其与脾静脉汇合处结扎,插管并注射钡后在X线下进行研究。另3例新生儿由阴茎背深静
The authors have shown that hemorrhoids are caused by mucosal prolapse caused by the contraction of the anorectal band (anorectal band) in the neck of the rectum and deny the hemorrhoid venous plexus congestion is a necessary condition for the formation of hemorrhoids. The above findings prompted the author to re-recognize the anatomy of hemorrhoid plexus. In this paper, 48 with normal genitourinary tract of corpses to study hemorrhoid venous plexus anatomy and its role in the formation of hemorrhoids. 48 dead bodies, 30 males and 18.20 females died of term infants after birth, the remaining 28 cases were aged 8 to 58 years. Divided into two groups angiography and angioplasty. Angiography group: 25 cases, using 20% barium sulfate aqueous solution as contrast agent. Seven neonates with inferior mesenteric veins were exposed, ligated with splenic vein, catheterized, and barium infused after radiography. Another 3 newborns from the penis deep static
