【摘要】： 目的:為深入了解脊髓節(jié)段性營(yíng)養(yǎng)動(dòng)脈在椎間孔及椎管內(nèi)的分支、分布及吻合情況,應(yīng)用乳膠脊髓節(jié)段性血管內(nèi)灌注法及單寧酸-氯化鐵媒染微血管的方法,對(duì)脊神經(jīng)節(jié)及脊髓節(jié)段性營(yíng)養(yǎng)血管的來(lái)源、分支、分布及其形態(tài)特點(diǎn)進(jìn)行了系列研究,為臨床上有關(guān)脊髓節(jié)段性血管損傷引發(fā)的多種脊髓及脊神經(jīng)病變的預(yù)防、脊柱外傷修復(fù)等提供可靠的應(yīng)用解剖學(xué)資料和參數(shù)。 方法 1選取15具成人軀干標(biāo)本,男女不限,使用紅色乳膠灌注液,經(jīng)T1～L5節(jié)段的脊髓節(jié)段性營(yíng)養(yǎng)動(dòng)脈進(jìn)行灌注。待乳膠液自然凝固后,逐個(gè)解剖節(jié)段動(dòng)脈,暴露其分支、分布情況,觀測(cè)節(jié)段動(dòng)脈在椎管外部的走行和吻合;從腹側(cè)去掉椎體,暴露椎管、椎間孔及其附近結(jié)構(gòu),觀察脊髓節(jié)段動(dòng)脈在椎管前部的走行及吻合情況,重點(diǎn)對(duì)穿入包繞脊神經(jīng)節(jié)硬脊膜鞘的脊支動(dòng)脈的來(lái)源、硬膜外的長(zhǎng)度進(jìn)行觀察和測(cè)量;切斷脊神經(jīng)根去除脊髓后觀察脊髓節(jié)段動(dòng)脈在椎管后部的走行及吻合情況。 2選取健康家兔20只,雌雄不限,體重1～1.5kg。耳緣靜脈麻醉后經(jīng)升主動(dòng)脈插管,溫生理鹽水(38℃)500～750ml快速灌流沖洗,然后灌注1000～1500ml含2%戊二醛、2%多聚甲醛、2%單寧酸的混合媒染固定液( 38℃),灌畢取出脊
[Abstract]:Objective: to investigate the branches, distribution and anastomosis of spinal segmental nutrient arteries in the intervertebral foramen and the spinal canal, we used the latex spinal cord segmental intravascular perfusion method and the method of microvascular staining with tannic acid-ferric chloride mordant. A series of studies on the origin, branches, distribution and morphological characteristics of spinal ganglion and spinal cord segmental nutrient vessels were carried out in order to prevent many kinds of spinal cord and spinal neuropathy caused by spinal cord segmental vascular injury. The repair of spinal trauma provides reliable applied anatomical data and parameters. Method 1Fifteen adult trunk specimens, male and female, were perfused with red latex perfusion solution through the spinal cord segmental nutrient artery of T _ 1 / L _ 5 segment. The segmental arteries were dissected one by one, their branches and distribution were exposed, and the passage and anastomosis of segmental arteries outside the spinal canal were observed. We removed the vertebral body from the ventral side, exposed the spinal canal, intervertebral foramen and its adjacent structure, observed the route and anastomosis of the spinal segmental artery in the anterior part of the spinal canal, and focused on the origin of the spinal branch artery penetrating the dural sheath around the spinal ganglia. The epidural length was observed and measured. After the spinal nerve root was cut off, the route and anastomosis of the spinal artery in the posterior part of the spinal canal were observed. 2Twenty healthy rabbits, male and female, were selected. The body weight was 1.5kg.After intravenous anaesthesia on the ear edge, the ascending aorta was intubated and the warm physiological saline was perfused quickly with 500-750ml at 38 鈩，
