The existence of collateral circulation in patients with impaired intracranial circulation was studied. We analysed angiograms of 35 patients of the Neurology Clinic of Clinical Centre in Sarajevo with occlusion of internal carotid artery. In majority cases collateral circulation was not established. In patients with occlusion of internal carotid artery, extracranial-intracranial anastomoses were established in some cases, with results of surviving and patients recovery. Collateral circulation based on blood vessels which are formed in the early stages of fetal life. Some embryonal arteries undergo an involution process, while the other part of blood vessels stay unfunctional during life, until cerebrovascular disease appearence, when it comes to their activation. Establishing of the collateral circulation in post-occlusiv status depend on great number of factors: number of anastomoses, their calibre,velocity of occlusion and complete vascular status of patients.
对颅内循环受损患者的侧支循环存在情况进行了研究。我们分析了萨拉热窝临床中心神经科35例颈内动脉闭塞患者的血管造影。在大多数情况下,侧支循环未建立。在颈内动脉闭塞患者中,部分病例建立了颅外-颅内吻合,患者存活并康复。侧支循环基于胎儿生命早期形成的血管。一些胚胎动脉经历退化过程,而另一部分血管在生命过程中保持无功能状态,直到脑血管疾病出现时才被激活。闭塞后侧支循环的建立取决于大量因素:吻合支数量、口径、闭塞速度以及患者的完整血管状态。
