【摘要】：目的通過回顧性采集顱內(nèi)動脈分叉部的血管形態(tài)幾何參數(shù),分析血管結(jié)構與動脈瘤發(fā)生的相關性,為后期前瞻性研究提供理論依據(jù)。方法通過回顧確診顱內(nèi)動脈瘤的病例資料,得到可以進行頸內(nèi)-后交通動脈分叉部分叉角、頸內(nèi)動脈和后交通動脈直徑測量的頸內(nèi)-后交通動脈分叉部動脈瘤共14例為研究組,非頸內(nèi)-后交通動脈分叉部動脈瘤共15例為對照組。分別測量兩組的頸內(nèi)-后交通動脈分叉部分叉角(Ap),后交通動脈直徑(Dp),頸內(nèi)動脈C6段(DC6)與C7段直徑(DC7),統(tǒng)計分析頸內(nèi)-后交通動脈分叉部血管形態(tài)幾何參數(shù)與動脈瘤發(fā)生的相關性。結(jié)果研究組頸內(nèi)-后交通動脈分叉部分叉角明顯小于對照組(P0.01)。根據(jù)分叉角進行分層,對分叉角在84°至120°的病例,進行頸內(nèi)-后交通動脈分叉部血管直徑的第二次統(tǒng)計分析,結(jié)果顯示研究組的后交通動脈直徑明顯小于對照組(P0.05);研究組后交通動脈與C6段直徑比值明顯小于對照組(P0.05)。結(jié)論頸內(nèi)-后交通動脈分叉部分叉角的大小與頸內(nèi)-后交通動脈分叉部動脈瘤的形成相關,分叉角越小越有可能形成動脈瘤;而在一定分叉角范圍內(nèi),后交通動脈與頸內(nèi)動脈直徑的比值與頸內(nèi)-后交通動脈分叉部動脈瘤的形成具有相關性,比值越小越有可能形成動脈瘤。
[Abstract]:Objective to analyze the correlation between angiostructures and aneurysms by collecting the morphological and geometric parameters of the bifurcation of intracranial arteries, and to provide a theoretical basis for the prospective study in the later stage. Methods by reviewing the data of patients with intracranial aneurysms, 14 cases of internal and posterior communicating artery bifurcation aneurysms were obtained in the study group. The internal and posterior communicating artery diameters of internal carotid artery and posterior communicating artery were measured. 15 cases of non-internal-posterior communicating artery bifurcation aneurysms were used as control group. The diameters of the internal and posterior communicating arteries of the internal carotid artery (C6 segment DC6) and the internal carotid artery (DC6 segment DC6) and the diameter of the C7 segment of the internal carotid artery (C7) were measured, respectively. The relationship between the morphological and geometric parameters of the bifurcation of the internal and posterior communicating artery and the occurrence of aneurysms was analyzed statistically. Results the forked angle of the internal-posterior communicating artery in the study group was significantly lower than that in the control group (P 0.01). According to the bifurcation angle, the second statistical analysis was made on the diameter of the bifurcation part of the internal posterior communicating artery in the patients with the bifurcation angle from 84 擄to 120 擄. The results showed that the diameter of the posterior communicating artery in the study group was significantly smaller than that in the control group (P 0.05), and the ratio of the diameter of the posterior communicating artery to the C6 segment in the study group was significantly smaller than that of the control group (P 0.05). Conclusion the size of the forked part of the internal and posterior communicating artery is related to the formation of the aneurysm in the bifurcation part of the internal and posterior communicating artery, and the smaller the angle of bifurcation is, the more likely it is to form the aneurysm, but within a certain range of bifurcation angles, The ratio of the diameter of the posterior communicating artery to the internal carotid artery is correlated with the formation of the bifurcation aneurysm of the internal and posterior communicating artery, and the smaller the ratio is, the more likely it is to form the aneurysm.
