神經(jīng)介入經(jīng)常需要用到血管直徑作為參考，查閱文獻摘錄如下：1.頸內(nèi)動脈的直徑：男性5.11±0.87 mm，女性4.66±0.78 mm。2.頸總動脈的直徑：男性6.52±0.98mm，女性6.10±0.80 mm。Measurements were obtained in 500 consecutive patients (age 52±15 years; 61% women). Mean diameters of ICA (4.66±0.78 mm) and CCA (6.10±0.80 mm) in women were significantly smaller than in men: 5.11±0.87 mm and 6.52±0.98 mm, respectively. Sex significantly influenced the diameters after controlling for body size, neck size, age, and blood pressure.來源于http://stroke.ahajournals.org/content/37/4/1103.full與這篇文章的數(shù)據(jù)有些差異：http://snamid.org/allegati/Effect%20of%20overweight%20on%20luminal%20diameter....pdfTable 1.

The diameter ranged from0.3 to 0.5 cm.來源于http://www.anatomyatlases.org/AnatomicVariants/Cardiovascular/Text/Arteries/CerebralMiddle.shtml5.大腦后動脈的直徑：右側(cè)2.1-2.75mm,左側(cè)1-2.5mm。A study of 89 formalin-fixed brain specimen of either sex and of Indian origin has showed that the mean lengthand diameter of the posterior cerebral artery was 6.75 ± 1.482 mm and 1.7 ± 0.7 mm respectively.Studies on the length of the posterior cerebral arteryby various authors have shown it to vary between6.8–7.5 mm. Diameter of the vessel was seen to bebetween 2.1–2.75 mm on right side and 1–2.5 mm onthe left side.來源于http://www.rjme.ro/RJME/resources/files/490108043045.pdf6.椎動脈的直徑：左側(cè)3.4mm,右側(cè)2.9mm。7.基底動脈的直徑：3-7mm(平均4.3mm)。長度24-35mm(平均24.9mm)。The mean diameter of the vertebral artery was 3.4 mm on the left and 2.9 mm on the right. The diameter of the basilar artery varied from 3-7 mm (mean of 4.3 mm). The length varied from 24-35 mm (mean of 24.9 mm).來源于http://www.bioline.org.br/abstract?ni07011
