Five cases of cerebro-vascular diseases with carotid-basilar anastomosis were evaluated. Case 1: a 73-year-old female was diagnosed as having subarachnoid hemorrhage due to a ruptured aneurysm of the right internal carotid artery-posterior communicating artery bifurcation and demonstrated that a left proatlantal intersegmental artery. Case 2: a 38-year-old female showed intraventricle hemorrhage due to arteriovenous malformation and showed left primitive hypoglossal artery. Case 3: 73-year-old female was diagnosed as having subarachnoid hemorrhage due to a ruptured basilar top aneurysm and demonstrated that a right primitive hypoglossal artery. Case 4: a 29-year-old male with unruptured aneurysm of the left internal carotid artery-posterior communicating artery bifurcation, and right trigeminal artery was detected incidentally by magnetic resonance angiography (MRA). Furthermore, right proatlantal intersegmental artery was detected by conventional angiography. Case 5: a 76-year-old male was diagnosed as having subarachnoid hemorrhage due to a ruptured aneurysm of the anterior communicating artery. MRA showed the aneurysm and a primitive trigeminal artery. No clinical symptom related with carotid-basilar anastomosis was detected. Magnetic resonance angiography (MRA) was useful for diagnosis of asymptomatic carotid-basilar anastomosis. Especially, axial view of MRA by time of flight method detected two cases of a primitive trigeminal artery. And coronal view of MRA by phase contrast method is useful for diagnosis of primitive proatlantal intersegmental artery. More asymptomatic persistent carotid-basilar anastomosis may be detected by MRA.
对5例伴有颈基底吻合的脑血管疾病患者进行了评估。病例1：一名73岁女性被诊断为右侧颈内动脉-后交通动脉分叉处动脉瘤破裂导致蛛网膜下腔出血，并显示有左侧寰椎前节间动脉。病例2：一名38岁女性因动静脉畸形出现脑室内出血，并显示有左侧原始舌下动脉。病例3：一名73岁女性被诊断为基底动脉顶端动脉瘤破裂导致蛛网膜下腔出血，并显示有右侧原始舌下动脉。病例4：一名29岁男性，左侧颈内动脉-后交通动脉分叉处有未破裂动脉瘤，磁共振血管造影（MRA）偶然发现右侧三叉动脉。此外，通过传统血管造影检测到右侧寰椎前节间动脉。病例5：一名76岁男性被诊断为前交通动脉动脉瘤破裂导致蛛网膜下腔出血。MRA显示了动脉瘤和一条原始三叉动脉。未检测到与颈基底吻合相关的临床症状。磁共振血管造影（MRA）对无症状颈基底吻合的诊断有用。特别是，飞行时间法的MRA轴位视图检测到2例原始三叉动脉。而相位对比法的MRA冠状位视图对原始寰椎前节间动脉的诊断有用。通过MRA可能会检测到更多无症状的持续性颈基底吻合。
