通过动脉栓塞和灌注、X 线摄片、透明、组织学切片等方法,观测了10例足月胎儿和新生儿头皮动脉的分布和吻合,并比较了不同大小的栓塞颗粒行颈外动脉栓塞后对头皮血供的影响.结果表明,脑膜廇术前行颈外动脉栓塞,产生头皮局部缺血性坏死与其栓塞范围、皮瓣切口及栓塞颗粒大小有关.提出合理设计开颅皮瓣的切口和选用适当栓塞颗粒的预防措施.
The distribution and anastomosis of 10 cases of full-term fetal and neonatal scalp arteries were observed by arterial embolization and perfusion, radiography, radiography and histological sections, and the embolization particles of different sizes were compared after embolization of the external carotid artery On the blood supply to the scalp.The results showed that the preoperative external carotid artery occlusion of the meningeal loop caused the scalp ischemic necrosis and its embolization range, flap incision and embolization particle size.The reasonable design of the craniotomy flap incision and Select the appropriate embolic particles preventive measures.
