A study on the normal cerebral artery of Korean adults by carotid angiography

Shin, H S

Abstract

The cerebral angiography was done in 212 normal Korean adults; 148 males and 64 females. The roentgenologic techniques were essentially the same with those described in the textbooks. The arterial configulations, distributional pattern of the intracarinial vessels, caliber sizes of the arteries and the position of the major arterial trunks were studied and statistically analysed. Following were the results; 1. The caliber sizes of the internal carotid arteries in the region of the intrapetrosal and intracavernous portion were; 4.7+0.66 mm in males and 4.3+0.1 mm in females of the 21-50 age groups, 5.2+0.13 mm in males and 4.1+0.24 mm in females of the 51-60 age groups. Those in the region of the carotid siph on were; 3.1+0.06 mm in males and 3.1+0.08 mm in females of the 21-50 age groups. 2. The caliber sized of the anterior cerebral arteries were; 1.5+0.03 mm in males and 1.4+0.04 mm infemales of the 21-50 age groups, 1.6+0.05 mm in males and 1.6+0.12 mm in females of the 51-60 age groups. Those ofthe middle cerebral arteries were; 1.6+0.03 mm in male and 1.5+0.07 mm in females of the 21-50 age groups,1.4+0.08 mm in males and 1.5+0.12 mm in females of the 21-50 age groups, 1.4+0.08 mm in males and 1.5+0.12 mm infemales of the 51-60 age groups. Those of the posterior cerebral arteries were; 1.3+0.07 mm in males and 1.4+0.1 mm in females of the 21-50 age groups, 1.2+0 mm in males and 1.5+0.22 mm in females of the 51-60 age groups. 3. Thedistances from the ascending vertical portion of the anterior cerebral arteries to the inner table of the frontalbone were; 39.6+0.41 mm in males and 40.4+0.54 mm in females of the 21-50 age groups. 35.3+1.49 mm in males and 33.7+1.02 mm in females of the 51-60 age groups. Those from the upper portion of the pericallosal arteries to the inner table of the parietal bone were; 40.6+0.5 mm in males and 40.2+0.91 mm in females of the 21-50 age groups,41.0+1.4 mm in males and 38.0+1.46 mm in females of the 51-60 age groups. Those from the lower portion of the pericallosal arteries to the inner table of the parietal bone were; 47.4+0.54 mm in males and 46.4+1.16 mm in females of the 21-50 age groups, 49.4+1.88 mm in males and 47.1+2.21 mm in females of the 51-60 age groups. 4. The morphological variations of the internal corotid arteries in the region of the carotid siphon and the intracavernous portion were; simple S type in 60.4%, double S type in 10.4% and transitonal type in 29.2%. 5. Thedeviations of the anterior certebral arteries to the midline were less than; 2 mm in 47.2%, 4 mm in 48.0%, 6 mm in2.0%, 8 mm and 10 mm in 1.5% each. 6. The distances from the angiographic sylvian point to the inner table of the temporal bone were; 36.6+0.45 mm in males and 34.8+0.65 mm in females of the 21-50 age groups, 35.7+1.72 mm in males and 35.6+1.98 mm in females of the 51-60 age groups. Those from the inner most limits of the middle cerebral arteries roughly outining the island of Reil to the inner table of the temporal bone were; 24.2+0.38 mm in males and 22.6+0.59 mm in females of the 21-50 age groups, 21.8+1.55 mm in males and 21.4+1.39 m in females of the 51-60 age groups. Those from the lowest major branch of the middle cerebral arteries to the clinoparietal line were;5.7+0.26 mm in males and 6.1+0.4 mm in females of the 21-50 age groups, 5.4+0.69 mm in males and 5.7+0.52 mm in females of the 51-60 age groups. Thus the distance from the lowest major branch of the middle cerebral arteries to the clinoparietal line in adults is less than that in children. 7. The distances from the most lateral branch ofthe lenticulostriate arteries to the midline were; 32.3+0.56 mm in males and 23.6+0.55 mm in females of the 21-50 age groups, 32.6+1.77 mm in males and 32.0+0.79 mm in females of the 51-60 age groups. Those from the most medial branch of the lenticulostriate arteries to the midline were; 22.3+0.72 mm in males and 20.6+0.75 mm in females of the 21-50 age groups, 19.9+0.72 mm in males and 23.7+0.51 mm in females of the 51-60 age groups. 8. The contralateral fillings of the media in the unilateral carotid angiograms were encountered in 28.0%. 9. The findings of the posterior communicating, posterior cerebral, ophthalmic and anterior choroidal arteries were encounted in 57.0%, 24.0%,74.0% and 83.0% respectively.
