查询词典 posterior

Inferior petrosal sinus extends from the posterior part of the cavernous sinus and courses along the clivus laterally, in IPS sulcus. It usually leaves cranial cavity through the jugular foramen and eventually joins the jugular bulb or the internal jugular vein.

岩下窦起自海绵窦后端，走行在斜坡两侧的IPS沟内，通常经颈静脉孔出颅，最终汇入颈静脉球或颈内静脉，沿途接收多条静脉的注入，与颅神经Ⅵ、Ⅸ、Ⅹ、Ⅺ关系密切。

The available operation range in clivus and anterior cranial base by transsphenoidal opproach was also observed during the operation under the help of neuronavigational pointer. Forty-one patients underwent sublabial, transseptal, transsphenoidal approach to the pituitary region guided by Surgical Microscope Navigation was studied. The piriform aperture was 27. 2mm±3. 1 , the origin of inferior nasal concha 30mm±4. 1, the origin of middle nasal concha 27. 9mm±4. 3. These data are important for transsphenoidal approach, because the piriform aperture and the origin of both inferior and middle nasal conchas restricted the opening width of the Hardy specula. If any distance of these bony structures was much less than the mean one, may cause inadequate opening of the specula blade and resulting dissatisfied operative field. Microadenomas or cystic tumors perhaps can be operated even in a narrow exposure, but large or giant solid adenomas may need a proper evaluation including changing the operative approach or performing a bilateral submucous inferior conchotomy or posterior ethmoidectomy firstly.

手术中还利用CT导航系统观察棒研究了经口—鼻蝶窦入路在斜坡区和前颅底能够达到的实际有效操作范围，为扩大经蝶窦入路手术在斜坡区和前颅底的应用奠定基础，在国内外尚未见同类报道。41例垂体瘤患者梨状孔平均宽度27.2mm±3.1，下鼻甲根部附着处间距30mm±4.1，中鼻甲根部附着处间距27.9mm±4.3，这是经口—鼻蝶窦入路手术中，对Hardy双瓣鼻窥器张开限制的主要骨性结构，若患者这些径线值明显小于平均值，则可能因为鼻窥器打开不充分而影响手术暴露，当然对于垂体微腺瘤和以囊变为主的垂体瘤可能影响不大，但对于大和巨大垂体瘤必须要有充分的准备，包括评估是否改用其他入路，或先行鼻甲切除再行经蝶手术。

METHODS: 10 mL bone marrow was extracted from dog posterior superior iliac spine, heparin anticoagulation, diluted using Hanks juice, treated with 1.077 g/mL Ficoll solution 3 mL, and centrifuged at 2 000 r/min for 20 minutes. Karyocytes were absorbed to form white cloudlike layering interface, and then centrifuged twice using DMEM supplemented with fetal bovine serum, incubated at 12×104/cm2 at 37 ℃ in a 5% CO2 incubator.
