Exploration of Morphological Change of Coronary Venous in Hypertensive Patient by Multi-slice Spiral CT

Objective To explore the morphology changes of the coronary venous system in hypertensive patients by using multi-slice spiral CT(MSCT).Methods Randomly selected 100 cases who accept multirow CT coronary angiography,including hypertensive patients 50 cases(24 cases are femal),average age 62.3± 9.7(35-78 years old) and healthy adults 50 cases(22 cases are male),average age58.6±7.7(44-77 years old).We studied by contrast enhanced MSCT which retrospective ECG-reconstructions.The length,diameter and morphology of hypertensive patients'coronary sinus were measured from both 3-dimersional volume rendered images and 2-dimersional cured planar images,and compared with the results in healthy adults 50 cases who accept multi-row CT coronary angiography.The main purpose was to observe the morphology change of the coronary venous system.A probability value p0.05 was considered statistically significant,p0.01 was considered quite statistically significant.Results The diameter of coronary sinus in hypertension patients:The average diameter of the coronary sinus orifice was 10.5.±32(4.2-20.8)mm.The total length of the coronary sinus was 35.6±9.0(13-61)mm.The coronary sinus average diameter in the middle cardiac vein was 9.8±2.2(5.5-15.8)mm.The coronary sinus average diameter in the left atrial oblique vein was 8.6±1.9(5.2-14.4)mm.The diameter of coronary sinus and its branches in healthy adults:The average diameter of the coronary sinus orifice was 10.6±3.5(4.6-17.9)mm.The total length of the coronary sinus was 34.8±7.5(13-61)mm;The coronary sinus average diameter in the middle cardiac vein was 8.9±2.2(3.8-11.8)mm;The coronary sinus average diameter in the left atrial oblique vein was 7.9±1.4(5.2-10.4)mm.The difference in the hypertensive patients and healthy adults:There were significant differences in the coronary sinus average diameter in the middle cardiac vein and in the left atrial oblique vein.Conclusion Hypertension makes the coronary sinus average diameter enlarged at the site of middle cardiac vein and in the left atrial oblique vein.
