[Determining the relationship between coronary artery and coronary sinus and its tributaries using multislice computed tomography].
OBJECTIVE
To obtain the coronary artery and coronary sinus (CS) and its tributaries imaging with multislice computed tomography (MSCT), measure the distance between coronary artery and CS and its tributaries and analyze their spatial relationships.


METHODS
The MSCT scans of 117 patients (67 men, 50 women, age 56 +/- 10 years) were obtained, 3D image reconstructed and the vessels courses evaluated. The concomitant distances and spatial relationships of the vessels were determined.


RESULTS
Right coronary artery domination was found in 107 cases (91.4%), left coronary artery domination in 7 cases (6.0%), and co-domination in 3 cases (2.6%). Left circumflex artery (LCX) was concomitant with CS or the great cardiac vein (GCV) in 81 cases (69.2%), intersected with left posterior vein in 62 cases (53.0%) and with middle cardiac vein (MCV) in 5 cases (4.3%), respectively. The dominant coronary artery branched out into the posterior descending artery (PDA) and the left posterior artery (LPA) in 112 cases (95.7%). PDA was concomitant with MCV in 93 cases (79.5%) and intersected with MCV in 44 cases (37.6%). LPA was intersected with MCV in 106 cases (90.6%), and concomitant with CS in 50 cases (42.7%).


CONCLUSIONS
MSCT is a reliable tool to visualize the relationship between coronary artery and CS and its tributaries. Owing to the multiple possibilities inherent to this technique, MSCT has broad potential for more clinical use.
