Abstract:
The morphometric study of arteries are the radial, ulnar, internal mammary (IMA), right gastroepiploic (RGEA), peroneal, posterior tibial and mid left anterior descending (mid LAD) in 37 Thai adult cadavers whose ages ranged from 45 to 91 years on the Department of Anatomy, Faculty of Medicine, Chulalongkorn University. The external diameter and length of arteries were measured by means of the Vernier caliper precision 0.02 mm and the Tape line, respectively. The mean external diameters of the radial artery, ulnar artery, IMA, RGEA, peroneal artery, posterior tibial artery and mid LAD were 2.67+-0.4, 2.22+-0.17, 2.39+-0.24, 2.65+-0.12, 2.58+-0.8, 4.57+-0.61 and 3.08+-0.62 mm, respectively. The mean lengths of the radial artery, ulnar artery, IMA, RGEA, peroneal artery and posterior tibial artery were 20.17+-1.68, 21.98+-1.68, 16.71+-1.02, 16.28+-1.71, 23.01+-1.43 and 23.27+-1.67 cm, respectively. The result of this study indicates that all of the study arteries are larger than 1.5 mm in diameter. Therefore, these arteries are suitable for a new choice of arterial conduits in coronary artery bypass graft (CABG). Especially the posterior tibial artery, it is suitable for CABG due to the largest in external diameter and the longest in length. In addition, this thesis has studied on the association between the external arterial diameter, arterial length and height and also body part representing by bony length. The result shows that the external arterial diameters were not correlated with both height and body part representing by bony length (p>0.05), but the arterial lengths were correlated with both height and body part representing by bony length (p<0.001).
